Title: Delivery plan presenting system, delivery plan presenting device, control method, program, and computer readable recording medium

Description:
TECHNICAL FIELD 
     The present invention relates to a delivery plan presenting system, a delivery plan presenting device, a control method, a program, and a computer-readable recording medium. Particularly, the present invention relates to: a delivery plan presenting system that presents a delivery plan suitable to a manufacturing capability of electrolysis water required by a client, as a delivery plan of a manufacturing machine of the electrolysis water to be presented to the client; a delivery plan presenting device; a control method of controlling the delivery plan presenting device; a program for the delivery plan presenting device; and a computer-readable recording medium storing therein the program for the delivery plan presenting device. 
     Priority is claimed on Japanese Patent Application No. 2010-239972, filed Oct. 26, 2010, the content of which is incorporated herein by reference. 
     BACKGROUND ART 
     A primal factor for bacterial and viral food poisoning is microorganism. Harmful bacteria and viruses contained in foods enter the body, thus causing acute gastroenteritis. Outbreaks of Bacterial and viral food poisoning used to occur in summer. However, many outbreaks thereof have recently occurred throughout the year. 
     For this reason, in order to sterilize microorganisms that cause bacterial and viral food poisoning, ingredients and the like are cleansed with electrolysis sterilized water in food factories and the like. The electrolysis sterilized water is manufactured by electrolyzing hydrochloric acid solution in a non-diaphragm electrolytic cell, and then diluting the hydrochloric acid solution with water by proper concentration. In other words, the manufacturing capability of electrolysis sterilized water is subject to the restriction of the productive capacity of electrolysis of the electrolytic cell. 
     The amount and the concentration of electrolysis sterilized water required in food factories or the like differ depending on the use thereof. For this reason, when a manufacturing machine of electrolysis sterilized water is introduced in a food factory or the like, it is necessary to introduce a manufacturing machine suitable for that use. However, the manufacturing capability of actual manufacturing machines of electrolysis sterilized water on sale, such as the amount and the concentration of the electrolysis sterilized water, is predefined for each type. For this reason, it is difficult to select a type with the manufacturing capability of electrolysis sterilized water suitable for the actual use. 
     Additionally, application of electrolysis sterilized water is expected in fields other than the food industry, such as a field of ships processing ballast water. Further, there are needs to design various types of machines, such as automatic milking machines and apparatus washing machines, so as to previously integrated an electrolytic cell therein (see, for example, Patent Documents 1 and 2). Selection of a type of electrolytic cell is important in such a case. 
     With respect to the above problems, it is required to provide a type of manufacturing machine of electrolysis water such as electrolysis sterilized water, which has specifications suitable to the needs of a client. As specific marketing methods, a marketing method of marketing various types with subdivided specifications, as products, and a custom-made method can be considered. However, in the former marketing method, all the types are not necessarily suitable to the needs of clients, thereby making it likely to create an excess in inventory. For this reason, it is not always possible to provide a proper type with specifications suitable for actual use. In the latter marketing method, there is no possibility of creating an excess in inventory, and therefore it is possible to provide a proper type with specifications suitable for actual use. Needless to say, however, the price increases in the latter marketing method. 
     As another marketing method achieving a good balance with the sales price, a pattern order marketing method can be considered. In this method, many patterns are prepared for part of the components of a manufacturing machine of electrolysis sterilized water, and those components are combined, thereby manufacturing and marketing a type suitable to the needs of clients. 
     As a marketing system using the pattern order method, a pattern order system is known. In this system, multiple standard dimension patterns for manufacturing products in different dimensions are previously prepared, a standard dimension pattern close to the body shape of a client is specified, and that standard dimension pattern is modified, thus supporting manufacture of a product for that client (see, for example, Patent Document 3). In this system, multiple combinations of predetermined dimension items among dimension items of the standard dimension patterns are stored in a storage device while being correlated to standard dimension pattern information including other items. Then, in this system, selection information relating to a design, a material, and the like, and measuring information obtained by a three-dimensional physical measurement device are received. Then, in this system, the storage device is searched based on the dimension of a predetermined item among the received measuring information, thus identifying the standard dimension pattern associated with that dimension. Then, the specified standard dimension pattern information is modified based on the dimension information concerning other items, which is included in the received measuring information, thereby obtaining client dimension pattern information. Then, in this system, a product for that client is manufactured based on the selection information and the client dimension pattern information.

     BEST MODE FOR CARRYING OUT THE INVENTION 
     Hereinafter, embodiments of the present invention are explained. However, the present invention is not limited to the following embodiments, and all combinations of the features explained in the embodiments are not always essential to solving means of the present invention. 
       FIG. 1  illustrates an example of a use environment of a delivery plan presenting system  100  according to an embodiment. The delivery plan presenting system  100  is a system for presenting a delivery plan of a manufacturing machine of slightly acidic hypochlorous acid water to be delivered to a client. Here, slightly acidic hypochlorous acid water may be an example of “electrolysis water” of the present invention. 
     The delivery plan presenting system  100  includes: a web server  110 ; multiple clients  140   a ,  140   b ,  140   c , . . . (hereinafter, collectively referred to as “client  140 ”); and a communication line  150 . Here, the web server  110  may be an example of the “delivery plan presenting device” of the present invention. 
     The communication line  150  includes a computer network such as the Internet, a core network for telecommunications carriers, and various local networks. The client  140  includes a mobile information terminal such as a mobile telephone and a PDA (personal digital assistants), and a personal computer. 
     The web server  110  is a computer that transmits to the client  140  via the communication line  150 , a delivery plan of a manufacturing machine of slightly acidic hypochlorous acid water. The web server  110  is operated by a provider that provides the delivery plan presenting system  100 . The client  140  is a computer that receives from the web server  110  via the communication line  150 , the delivery plan of a manufacturing machine of slightly acidic hypochlorous acid water. The client  140  is used by a client who is going to buy a manufacturing machine of slightly acidic hypochlorous acid water, or a salesman who tries to sell a manufacturing machine of slightly acidic hypochlorous acid water to a client. 
     In the delivery plan presenting system  100 , when a client buys a manufacturing machine of slightly acidic hypochlorous acid water, the client transmits data indicating required conditions to the web server  110  using the client  140 . Specifically, the conditions required by the client include; the concentration of chlorine in slightly acidic hypochlorous acid water; the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per day; the maximum value of an operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water; and conditions emphasized in buying a manufacturing machine of slightly acidic hypochlorous acid water. Upon receiving from the client  140 , the data indicating the conditions required by the client, the web server  110  calculates the estimated amount of chlorine to be required per day, based on the concentration of chlorine in slightly acidic hypochlorous acid water which is required by the client and the maximum amount of slightly acidic hypochlorous acid water manufactured per day which is required by the client. Then, based on the area, the current efficiency, and the optimal current density of an electrode plate selectable as an electrode of the electrolytic cell included in the manufacturing machine of slightly acidic hypochlorous acid water, the maximum value of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client, and the electrochemical equivalent of chlorine, the web server  110  calculates, for each electrode plate of multiple types, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates. Then, based on the estimated amount of chlorine to be required per day, which is calculated in the above manner, and the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates, which is calculated in the above manner for each electrode plate, the web server  110  calculates, for each electrode plate, the number of electrode plates required to generate the estimated amount of chlorine to be required per day which is calculated in the above manner. Then, based on the conditions for the manufacturing machine of slightly acidic hypochlorous acid water which are emphasized by the client, the web server  110  selects at least one specification of an electrolytic cell from among specifications of the respective electrolytic cells constituted by each electrode plate. Then, the web server  110  generates a delivery plan that presents the selected specification of the electrolytic cell including information concerning the number of electrode plates in the electrolytic cell with the specification selected in the above manner, or the specification of the manufacturing machine of slightly acidic hypochlorous acid water including that electrolytic cell. Then, the web server  110  transmits to the client  140 , a web page showing the delivery plan generated in this manner. 
     Thus, when a client buys a manufacturing machine of slightly acidic hypochlorous acid water, the client transmits data indicating required conditions, to the web server  110  using the client  140 . Thus, the client can obtain a delivery plan indicating the specification of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cell having a configuration suitable to those conditions. 
     Here, chlorine may be an example of an “active substance” of the present invention. Additionally, the period of “per day” may be an example of a “unit duration” of the present invention. Further, the area, the current efficiency, and the optimal current density of an electrode plate may be an example of a “specification of an electrode plate” of the present invention. Moreover, the web page showing the delivery plan may be an example of “data indicating a delivery plan” of the present invention. 
     Additionally, in the delivery plan presenting system  100 , when a client buys a manufacturing machine of slightly acidic hypochlorous acid water, if the client further requires the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per hour, the client transmits data indicating that additional requirement, to the web server  110  using the client  140 . Upon receiving from the client  140 , data that further requires the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per hour, the web server  110 , when calculating the estimated amount of chlorine to be required per day, the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per day, based on the maximum value of the manufacturing amount per hour which is required by the client and the maximum value of an operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client. Then, the web server  110  calculates the estimated amount of chlorine to be required per day, based on the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per day, which is calculated in this manner, and the concentration of chlorine in slightly acidic hypochlorous acid water which is required by the client. Then, the web server  110  generates a delivery plan of the manufacturing machine of slightly acidic hypochlorous acid water in the above manner, and transmits to the client  140 , a web page showing the delivery plan. 
     Thus, when a client buys the manufacturing machine of slightly acidic hypochlorous acid water, if the client further requires the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per hour, the client transmits data indicating that additional requirement, to the web server  110  using the client  140 . Thereby, the client can obtain a delivery plan showing the specification of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cell having the configuration suitable to those conditions. 
     Here, the period of “per day” may be an example of the “unit duration” of the present invention. 
     Additionally, in the delivery plan presenting system  100 , when a client buys a manufacturing machine of slightly acidic hypochlorous acid water including multiple electrolytic cells, the client transmits data indicating the desired number of electrolytic cells, to the web server  110  using the client  140 . Upon receiving from the client  140 , the data indicating the desired number of electrolytic cells, the web server  110  calculates the estimated amount of chlorine to be required per day, by regarding the value obtained by dividing the maximum value of the amount of electrolysis water manufactured per day which is required by the client, by the number of electrolytic cells required by the client, as the maximum number of the amount of electrolysis water manufactured per day which is required by the client. Then, the web server  110  generates a delivery plan of the manufacturing machine of slightly acidic hypochlorous acid water in the above manner, and transmits to the client  140 , a web page showing that delivery plan. 
     Thus, when a client buys the manufacturing machine of slightly acidic hypochlorous acid water including multiple electrolytic cells, the client transmits data indicating the desired number of electrolytic cells to the web server  110  using the client  140 . Thereby, the client can obtain a delivery plan showing the specification of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cells having the configurations suitable to the additional conditions. 
     Additionally, in the delivery plan presenting system  100 , when a client buys a manufacturing machine of slightly acidic hypochlorous acid water, if the client wants to receive periodical maintenance service for the manufacturing machine of slightly acidic hypochlorous acid water, the client transmits to the web server  110  using the client  140 , data indicating the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed. Upon receiving from the client  140 , the data indicating the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed, the web server  110  specifies an estimated frequency at which a maintenance agency visits the address and maintains the manufacturing machine of slightly acidic hypochlorous acid water, based on the information concerning the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed. Then, based on the estimated frequency of maintaining the manufacturing machine of slightly acidic hypochlorous acid water which is specified in this manner, and the maximum value of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client, the web server  110  calculates the total operating time estimated as an operating time of the manufacturing machine of slightly acidic hypochlorous acid water, in a period from the time when the maintenance is conducted by the maintenance agency to the time when the next maintenance is conducted. Then, the web server  110  determines, for each electrode plate, whether or not the lifetime of the electrode plate is longer than the total operating time calculated in this manner. Then, when the web server  110  calculates, for each electrode plate of multiple types, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates, the web server  110  calculates, only for the electrode plate whose lifetime is determined to be longer than the total operating time, the estimated amount of chlorine based further on the lifetime of that electrode plate and the calculated total operating time. Then, the web server  110  generates a delivery plan of the manufacturing machine of slightly acidic hypochlorous acid water in the above manner, and transmits to the client  140 , a web page showing that delivery plan. 
     Thus, when a client buys a manufacturing machine of slightly acidic hypochlorous acid water, if the client wants to receive periodical maintenance service for the manufacturing machine of slightly acidic hypochlorous acid water, the client transmits to the web server  110  using the client  140 , data indicating the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed. Thereby, the client can obtain a delivery plan showing the specification of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cell having the configuration suitable to receiving the periodical maintenance service. 
     Here, the address may be an example of an “address” of the present invention. 
     Additionally, in the delivery plan presenting system  100 , based on the number of electrode plates calculated in the above manner for each electrode plate and the price of each electrode plate, the web server  100  calculates the price of each electrolytic cell to be constituted by that electrode plate. Then, if the condition for the manufacturing machine of slightly acidic hypochlorous acid water which is emphasized by the client is that the price of the manufacturing machine of slightly acidic hypochlorous acid water be cheaper, the web server  110  selects at least one specification of an electrolytic cell that is cheaper in price, based on the price of each electrolytic cell calculated in this manner. Then, the web server  110  generates a delivery plan of the manufacturing machine of slightly acidic hypochlorous acid water in the above manner, and transmits to the client  140 , a web page showing that delivery plan. 
     Thus, when a client buys a manufacturing machine of slightly acidic hypochlorous acid water, if the client further requires that the price of the manufacturing machine of slightly acidic hypochlorous acid water be cheaper, the client transmits to the web server  110  using the client  140 , data indicating that requirement.

The area is a value indicating the area of a plate surface of the electrode plate identified by the electrode plate ID. The current efficiency is a value indicating the rate of current to be used for the intended electrode reaction, that current being one of currents passing the electrode plate identified by the electrode ID. The optimal current density is a value indicating the amount of current per unit area of the electrode, which is optimal to invoke the intended electrode reaction. The lifetime is a value indicating the lifetime of the electrode plate identified by the electrode ID when the current of the value indicated by the optimal current density flows. The price is the price of the electrode plate identified by the electrode plate ID. Here, the price of an electrode plate with an electrode bar may differ from the price of an electrode plate disposed between two electrode plates with electrode bars.

The list box  185  is a strip input region for selecting one of options of addresses as the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed. The radio button  186  is input means for selecting only one of options of the price, the dimensions, and the lifetime of the manufacturing machine of slightly acidic hypochlorous acid water, which are conditions empathized by the client when the client buys the manufacturing machine of slightly acidic hypochlorous acid water. The list box  187  is a strip input region for selecting one of options of the numbers of electrolytic cells, which is desired by the client. The list box  188  is a strip input region for selecting one of options of the numbers of delivery plans of the manufacturing machine of slightly acidic hypochlorous acid water, which is desired by the client.

       FIG. 6  illustrates an example of a web page  190  generated by the delivery plan generating unit  123  of the web server  110 . The web page  190  presents the number of electrode plates to be used in the electrolytic cell, the dimension of the manufacturing machine of slightly acidic hypochlorous acid water, the price of the manufacturing machine of slightly acidic hypochlorous acid water, and the maintenance frequency. 
       FIG. 7  illustrates an example of an operational sequence for the web server  110  and the client  140 . Explanations of the operational sequence are given here with reference to  FIGS. 1 to 6 . 
     When a client or salesman wants to obtain a delivery plan using the delivery plan presenting system  100 , the client or salesman accesses, using the client  140 , the web site provided by the web server  110 . At this time, for example, the web page  180  as shown in  FIG. 5  is shown on a display of the client  140 . The client inputs required conditions in the text boxes  181  to  184 , the list boxes  185 ,  187 , and  188 , and the radio button  186 , which are provided on the web page  180 . It is assumed in this example that “20 (ppm(mg/L))” is input in the text box  181 , “6000 (L)” is input to the text box  182 , “700 (L/h)” is input to the text box  183 , and “10 (h)” is input to the text box  184 . It is further assumed in this example that “Tokyo-to” is selected from the options of the list box  185 . It is further assumed in this example that “Price” is selected from the options of the radio button  186 . It is further assumed in this example that “1” is selected from the options of the radio button  187 . It is further assumed in this example that “1” is selected from the options of the list box  188 . Then, the client operates a pointing device to give an instruction while placing a cursor on the button  189 . Thus, the client  140  receives an input of data indicating the conditions required by the client. 
     Then, the client transmits to the web server  110 , the data received in the above manner (S 101 ). Upon receiving from the client  140 , the data indicating the conditions required by the client, the required condition data entry unit  113  of the web server  110  receives an input of that data. The required condition data entry unit  113  outputs to the delivery plan data output unit  124 , data indicating an IP (Internet Protocol) address of the client  140  having transmitted the received data. Additionally, the required condition data entry unit  113  outputs to the generated amount calculating unit  118 , data indicating the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client. In this example, the conditions indicated by the received data include the maximum value “700 (L/h)” of the amount of slightly acidic hypochlorous acid water manufactured per hour which is required by the client. Accordingly, the required condition data entry unit  113  outputs to the required amount calculating unit  114 , the concentration “20 (ppm(mg/L))” of chlorine in slightly acidic hypochlorous acid water which is required by the client, the maximum value “700 (L/h)” of the amount of slightly acidic hypochlorous acid water manufactured per hour which is required by the client, and the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client. Additionally, in this example, the conditions indicated by the received data include the information “Tokyo-to” that is the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed. Accordingly, the required condition data entry unit  113  outputs to the maintenance frequency specifying unit  115 , data indicating the information “Tokyo-to” that is the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed, and output to the total operating time calculating unit  116 , data indicating the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client. Further, in this example, the conditions indicated by the received data include the number of required electrolytic cells “1”. Accordingly, the required condition data entry unit  113  outputs to the required amount calculating unit  114 , data indicating the number of required electrolytic cells “1”. Moreover, in this example, the conditions indicated by the received data include the “price” as the condition for the manufacturing machine of slightly acidic hypochlorous acid water which is emphasized by the client. Accordingly, the required condition data entry unit  113  outputs to the specification selecting unit  122 , data indicating the condition “price” as the condition for the manufacturing machine of slightly acidic hypochlorous acid water which is emphasized by the client, and the number of delivery plans of the manufacturing machine of slightly acidic hypochlorous acid water “1” which is required by the client. 
     Upon receiving from the required condition data entry unit  113 , data indicating: the concentration “20 (ppm(mg/L))” of chlorine in slightly acidic hypochlorous acid water which is required by the client; the maximum value “700 (L/h)” of the amount of slightly acidic hypochlorous acid water manufactured per hour which is required by the client; and the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client; and the number of required electrolytic cells “1”, the required amount calculating unit  114  calculates the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per day, based on the maximum value “700 (L/h)” of the amount of slightly acidic hypochlorous acid water manufactured per hour which is required by the client, and the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client. For example, the required amount calculating unit  114  calculates the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per day, as in the following Formula (1). 
       [Formula 1] 
       Maximum value of manufacturing amount per day (L)=Maximum value of manufacturing amount per hour (L/h)×Maximum value of operating time per day (h)  (1)
 
     In this example, the maximum value of the amount of slightly acidic hypochlorous acid water manufactured per day is 700 (L/h)×10 (h)=7000 (L). Then, the required amount calculating unit  114  calculates the estimated amount of chlorine to be required per day, based on the maximum value “7000 (L)” of the amount of slightly acidic hypochlorous acid water manufactured per day which is calculated in this manner, the concentration “20 (ppm(mg/L))” of chlorine in slightly acidic hypochlorous acid water which is required by the client, and the number of required electrolytic cell “1 (cell)” (S  102 ). For example, the required amount calculating unit  114  calculates the estimated amount of chlorine to be required per day, as in the following Formula (2). 
       [Formula 2] 
       Estimated amount of available chlorine to be required per day (g)=Concentration of available chlorine (ppm(mg/L))×Maximum value of manufacturing amount per day (L)/Number of electrolytic cells (cell)/1000  (2)
 
     In this example, the estimated amount of chlorine to be required per day is 20 (ppm(mg/L))×7000 (L)/1 (cell)/1000=140 (g). Then, the required amount calculating unit  114  outputs to the calculating unit of the number of electrode plates  119 , data indicating the estimated amount “140 (g)” of chlorine to be required per day. 
     On the other hand, upon receiving from the required condition data entry unit  113 , data indicating information “Tokyo-to” that is the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed, the maintenance frequency specifying unit  115  specifies the estimated frequency at which the maintenance agency visits “Tokyo-to” and maintains the manufacturing machine of slightly acidic hypochlorous acid water, based on the information “Tokyo-to” that is the address at which the manufacturing machine of slightly acidic hypochlorous acid water is to be installed, and the information stored by the maintenance contractors information data storage unit  112  (step S 103 ). For example, in a case where the maintenance contractors information data storage unit  112  stores the information as shown in  FIG. 4 , the maintenance frequency specifying unit  115  specifies a record stored in association with the “Tokyo-to” as service area information. In this example, “Tokyo-to” is stored as service area information in the record of the contractor ID “m001”. Accordingly, the maintenance frequency specifying unit  115  specifies “365 (day/time)” as maintenance frequency information in the record of the contractor ID “m001”. Then, the maintenance frequency specifying unit  115  outputs to the total operating time calculating unit  116  and the delivery plan generating unit  123 , data indicating the estimated frequency “365 (day/time)” of maintaining the manufacturing machine of slightly acidic hypochlorous acid water, which is specified in this manner. 
     Then, upon receiving from the required condition data entry unit  113 , data indicating the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client, and receiving from the maintenance frequency specifying unit  115 , data indicating the estimated frequency “365 (day/time)” of maintaining the manufacturing machine of slightly acidic hypochlorous acid water, the total operating time calculating unit  116  calculates the total operating time that can be estimated as a time for which the manufacturing machine of slightly acidic hypochlorous acid water is operated, in a period from the time when the manufacturing machine of slightly acidic hypochlorous acid water is maintained by the maintenance agency to the time when the manufacturing machine of slightly acidic hypochlorous acid water is maintained the next time (S  104 ). For example, the total operating time calculating unit  116  calculates the total operating time as in the following Formula (3). 
       [Formula 3] 
       Total operating time (h)=Maximum value of operating time per day (h)×Estimated frequency of maintenance (day/time)  (3)
 
     In this example, the total operating time is 10 (h)×365 (day/time)=3650 (h). Then, the total operating time calculating unit  116  outputs to the lifetime evaluation unit  117 , data indicating the total operating time “3650 (h)” calculated in this manner. 
     Upon receiving from the total operating time calculating unit  116 , data indicating the total operating time “3650 (h)”, the lifetime evaluation unit  117  determines, based on the information stored by the electrode plate information data storage unit  111 , whether or not the lifetime of the electrode plate is longer than the total operating time “3650 (h)”, for each electrode plate of multiple types selectable as electrodes of the manufacturing machine of slightly acidic hypochlorous acid water (S 105 ). For example, in a case where the electrode plate information data storage unit  111  stores the information as shown in  FIG. 3 , the lifetime evaluation unit  117  determines whether or not a value of the lifetime stored in each record is longer than the total operating time “3650 (h)”. In this example, the values of lifetime in the records of the electrode plate IDs “a101”, “a102”, “a103”, “a201”, “a202”, “a203”, “c101”, “c102”, and “c103” are longer than the total operating time “3650 (h)”. Accordingly, the lifetime evaluation unit  117  determines that the lifetimes of the electrode plates identified by those electrode plate IDs are longer than the total operating time “3650 (h)”. Then, the lifetime evaluation unit  117  outputs to the generated amount calculating unit  118 , data indicating the electrode IDs “a101”, “a102”, “a103”, “a201”, “a202”, “a203”, “c101”, “c102”, and “c103”. 
     Then, upon receiving from the required condition data entry unit  113 , data indicating the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client, receiving from the total operating time calculating unit  116 , data indicating the total operating time “3650 (h), and receiving from the lifetime evaluation unit  117 , data indicating the electrode IDs “a101”, “a102”, “a103”, “a201”, “a202”, “a203”, “c101”, “c102”, and “c103”, the generated amount calculating unit  118  calculates the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates, only for the electrode plates identified by the electrode IDs “a101”, “a102”, “a103”, “a201”, “a202”, “a203”, “c101”, “c102”, and “c103”, based on the maximum value “10 (h)” of the operating time per day of the manufacturing machine of slightly acidic hypochlorous acid water which is required by the client, the electrochemical equivalent of chlorine “35.5”, the total operating time “3650 (h), and the information stored by the electrode plate information data storage unit  111  (S 106 ). For example, the generated amount calculating unit  118  calculates the estimated amount of chlorine to be generated per day, as in the following Formula (4). 
       [Formula 4] 
       Estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates (g)=Optimal current density (A/dm 2 )×Area (dm 2 )×(Current efficiency (%)/100)×Maximum value of operating time per day (h)×60 (min)×60 (s)×(36.5 (electrochemical equivalent of available chlorine)/96500 (Faraday constant))×(Lifetime (h)/Total operating time (h))  (4)
 
     In this example, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “a101” is 4 (A/dm 2 )×0.25 (dm 2 )×(90/100)×10×60×60×(35.5/96500)×(4000 (h))/3650 (h))≈13 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “a102” is 52 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “a103” is 208 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “a201” is 16 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “a202” is 65 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “a203” is 261 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “c101” is 24 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “c102” is 98 (g). Similarly, the estimated amount of chlorine to be generated per day in one electrolytic cell using two electrode plates identified by the electrode plate ID “c103” is 394 (g). Then, the generated amount calculating unit  118  outputs to the calculating unit of the number of electrode plates  119 , data indicating the amounts of chlorine calculated for the respective electrode plates “a101: 13 (g)”, “a102: 52 (g)”, “a103: 208 (g)”, “a201: 16 (g)”, “a202: 65 (g)”, “a203: 261 (g)”, “c101: 24 (g)”, “c102: 98 (g)”, and “c103: 394 (g)”. 
     Then, upon receiving from the required amount calculating unit  114 , data indicating the estimated amount “140 (g)” of chlorine to be required per day, and receiving from the generated amount calculating unit  118 , data indicating the amounts of chlorine calculated for the respective electrode plates “a101: 13 (g)”, “a102: 52 (g)”, “a103: 208 (g)”, “a201: 16 (g)”, “a202: 65 (g)”, “a203: 261 (g)”, “c101: 24 (g)”, “c102: 98 (g)”, and “c103: 394 (g)”, the calculating unit of the number of electrode plates  119  calculates the number of electrode plates required to generate per day the estimated amount of chlorine to be required per day “140 (g)”, for each of the electrode plates identified by the electrode IDs “a101”, “a102”, “a103”, “a201”, “a202”, “a203”, “c101”, “c102”, and “c103”, based on the estimated amount of chlorine to be required per day “140 (g)” and the amounts of chlorine calculated for the respective electrode plates “a101: 13 (g)”, “a102: 52 (g)”, “a103: 208 (g)”, “a201: 16 (g)”, “a202: 65 (g)”, “a203: 261 (g)”, “c101: 24 (g)”, “c102: 98 (g)”, and “c103: 394 (g)” (S 107 ). For example, the calculating unit of the number of electrode plates  119  calculates the number of required electrode plates as in the following Formula (5). 
       [Formula 5] 
       Number of required cells (cell)=(Estimated amount of available chlorine to be required per day (g)/Estimated amount of available chlorine to be generated per day (g)) where a quotient is rounded up.  (5)
 
     Number of required electrode plates (plate)=Number of required cells+1 
     In this example, the number of cells required in the case of using the electrode plate identified by the electrode ID “a101” is (140 (g)/13 (g))=10.7, which is rounded up to 11 (cell). Accordingly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a101” is 11+1=12 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a102” is 4 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a103” is 2 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a201” is 10 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a202” is 4 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a203” is 2 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “c101” is 7 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “a102” is 3 (plate). Similarly, the number of electrode plates required in the case of using the electrode plate identified by the electrode ID “c103” is 2 (plate). Then, the calculating unit of the number of electrode plates  119  outputs to the price calculating unit  120 , the dimensions calculating unit  121 , and the delivery plan generating unit  123 , data indicating the numbers of electrode plates calculated for the respective electrode plates, which are “a101: 12 (plate)”, “a102: 4 (plate)”, “a103: 2 (plate)”, “a201: 10 (plate)”, “a202: 4 (plate)”, “a203: 2 (plate)”, “c101: 7 (plate)”, “c102: 3 (plate)”, and “c103: 2 (plate)”. 
     Then, upon receiving from the calculating unit of the number of electrode plates  119 , the data indicating the numbers of electrode plates calculated for the respective electrode plates, which are “a101: 12 (plate)”, “a102: 4 (plate)”, “a103: 2 (plate)”, “a201: 10 (plate)”, “a202: 4 (plate)”, “a203: 2 (plate)”, “c101: 7 (plate)”, “c102: 3 (plate)”, and “c103: 2 (plate)”, the price calculating unit  120  calculates the price of each electrolytic cell to be constituted by the electrode plate, based on the numbers of electrode plates calculated for the respective electrode plates, which are “a101: 12 (plate)”, “a102: 4 (plate)”, “a103: 2 (plate)”, “a201: 10 (plate)”, “a202: 4 (plate)”, “a203: 2 (plate)”, “c101: 7 (plate)”, “c102: 3 (plate)”, and “c103: 2 (plate)”, and the information stored by the electrode plate information data storage unit  111  (S  108 ). For example, the price calculating unit  120  calculates the price of the electrolytic cell as in the following Formula (6). 
       [Formula 6] 
       Price of electrolytic cell (yen)=Unit price of electrode plate with electrode bar (yen)×2 (plate)+Unit price of intermediate electrode plate (yen)×(Number of required electrode plates (plate)−2 (plate))  (6)
 
     In this example, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a101” is 30000 (yen)×2 (plate)+17500 (yen)×10 (plate)=235000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a102” is 480000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a103” is 1700000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a201” is 330000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a202” is 790000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a203” is 2300000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “c101” is 375000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “c102” is 1030000 (yen). Similarly, the price of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “c103” is 3200000 (yen). Then, the price calculating unit  120  outputs to the specification selecting unit  122  and the delivery plan generating unit  123 , data indicating the prices of the respective electrolytic cells constituted in this manner, which are “a101: 235000 (yen)”, “a102: 480000 (yen)”, “a103: 1700000 (yen)”, “a201: 330000 (yen)”, “a202: 790000 (yen)”, “a203: 2300000 (yen)”, “c101: 3200000 (yen)”, “c102: 1030000 (yen)”, and “c103: 3200000 (yen)”. 
     On the other hand, upon receiving from the calculating unit of the number of electrode plates  119 , data indicating the numbers of electrode plates calculated for the respective electrode plates, which are “a101: 12 (plate)”, “a102: 4 (plate)”, “a103: 2 (plate)”, “a201: 10 (plate)”, “a202: 4 (plate)”, “a203: 2 (plate)”, “c101: 7 (plate)”, “c102: 3 (plate)”, and “c103: 2 (plate)”, the dimensions calculating unit  121  calculates the dimensions of each electrolytic cell to be constituted by the electrode plate, based on the numbers of electrode plates calculated for the respective electrode plates, which are “a101: 12 (plate)”, “a102: 4 (plate)”, “a103: 2 (plate)”, “a201: 10 (plate)”, “a202: 4 (plate)”, “a203: 2 (plate)”, “c101: 7 (plate)”, “c102: 3 (plate)”, and “c103: 2 (plate)”, and the information stored by the electrode plate information data storage unit  111  (S  109 ). For example, the dimensions calculating unit  121  calculates the dimension of the electrolytic cell as in the following Formula (7). 
       [Formula 7] 
       Dimension of electrolytic cell (height (mm)×depth (mm)×width (mm))
 
       Height, Depth=√{square root over (Area)}×100
 
       Width=2 (number of electrode plates with electrode bars)×1 (width of electrode plates with electrode bars)+(Number of electrode plates−2)(number of intermediate electrode plates)×0.5 (width of intermediate electrode plate)+(Number of electrode plates−1)(number of cells)×3 (width of cell)  (7)
 
     In this example, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a101” are the height=0.5×100=50 (mm), the depth=50 (mm), and the width=2×1+(12−2)×0.5+(12−1)×3=40 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a102” are the height=100 (mm), the depth=100), and the width=12 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a103” are the height=200 (mm), the depth=200 (mm), and the width=5 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a201” are the height=50 (mm), the depth=50 (mm), and the width=33 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a202” are the height=100 (mm), the depth=100 (mm), and the width=12 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “a203” are the height=200 (mm), the depth=200 (mm), and the width=5 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “c101” are the height=50 (mm), the depth=50 (mm), and the width=22.5 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “c102” are the height=100 (mm), the depth=100 (mm), and the width=8.5 (mm). Similarly, the dimensions of the electrolytic cell constituted by the electrode plate identified by the electrode plate ID “c103” are the height=200 (mm), the depth=200 (mm), and the width=5 (mm). Then, the price calculating unit  120  outputs to the specification selecting unit  122  and the delivery plan generating unit  123 , data indicating the dimensions of the respective electrolytic cells constituted in this manner, which are “a101: 50 (mm)×50 (mm)×40 (mm)”, “a102: 100 (mm)×100 (mm)×12 (mm)”, “a103: 200 (mm)×200 (mm)×5 (mm)”, “a201: 50 (mm)×50 (mm)×33 (mm)”, “a202: 100 (mm)×100 (mm)×12 (mm)”, “a203: 200 (mm)×200 (mm)×5 (mm)”, “c101: 50 (mm)×50 (mm)×22.5 (mm)”, “c102: 100 (mm)×100 (mm)×8.5 (mm)”, and “c103: 200 (mm)×200 (mm)×5 (mm)”. 
     Then, in this example, the specification selecting unit  122  receives from the required condition data entry unit  113 , data indicating the condition of “price” as the condition for the manufacturing machine of slightly acidic hypochlorous acid water which is emphasized by the client, and the number of delivery plans “1” of the manufacturing machine of slightly acidic hypochlorous acid water which is desired by the client. Accordingly, upon receiving from the price calculating unit  120 , data indicating the prices of the respective electrolytic cells, which are “a101: 235000 (yen)”, “a102: 480000 (yen)”, “a103: 1700000 (yen)”, “a201: 330000 (yen)”, “a202: 790000 (yen)”, “a203: 2300000 (yen)”, “c101: 3200000 (yen)”, “c102: 1030000 (yen)”, and “c103: 3200000 (yen)”, the specification selecting unit  122  selects one specification of an electrolytic cell which is cheaper in price, based on the prices of the respective electrolytic cells, which are “a101: 235000 (yen)”, “a102: 480000 (yen)”, “a103: 1700000 (yen)”, “a201: 330000 (yen)”, “a202: 790000 (yen)”, “a203: 2300000 (yen)”, “c101: 3200000 (yen)”, “c102: 1030000 (yen)”, and “c103: 3200000 (yen)” (S 110 ). In this example, the specification selecting unit  122  selects the specification of the electrolytic cell using the electrode plate identified by the electrode plate ED “a101”, as the specification of the cheapest electrolytic cell. Then, the specification selecting unit  122  outputs to the delivery plan generating unit  123 , data indicating that the specification of the electrolytic cell using the electrode plate identified by the electrode plate ID “a101” is selected. 
     Thus, the delivery plan generating unit  123  receives from the maintenance frequency specifying unit  115 , the data indicating the estimated frequency “365 (day/time)” of maintaining the manufacturing machine of slightly acidic hypochlorous acid water. Additionally, the delivery plan generating unit  123  receives from the calculating unit of the number of electrode plates  119 , the data indicating the numbers of electrode plates calculated for the respective electrode plates, which are “a101: 12 (plate)”, “a102: 4 (plate)”, “a103: 2 (plate)”, “a201: 10 (plate)”, “a202: 4 (plate)”, “a203: 2 (plate)”, “c101: 7 (plate)”, “c102: 3 (plate)”, and “c103: 2 (plate)”. Further, the delivery plan generating unit  123  receives from the price calculating unit  120 , the data indicating the prices of the respective configurable electrolytic cells, which are “a101: 235000 (yen)”, “a102: 480000 (yen)”, “a103: 1700000 (yen)”, “a201: 330000 (yen)”, “a202: 790000 (yen)”, “a203: 2300000 (yen)”, “c101: 3200000 (yen)”, “c102: 1030000 (yen)”, and “c103: 3200000 (yen)”. Moreover, the delivery plan generating unit  123  receives from the dimensions calculating unit  121 , the data indicating the dimensions of the respective electrolytic cells constituted in this manner, which are “a101: 50 (mm)×50 (mm)×40 (mm)”, “a102: 100 (mm)×100 (mm)×12 (mm)”, “a103: 200 (mm)×200 (mm)×5 (mm)”, “a201: 50 (mm)×50 (mm)×33 (mm)”, “a202: 100 (mm)×100 (mm)×12 (mm)”, “a203: 200 (mm)×200 (mm)×5 (mm)”, “c101: 50 (mm)×50 (mm)×22.5 (mm)”, “c102: 100 (mm)×100 (mm)×8.5 (m)”, and “c103: 200 (mm)×200 (mm)×5 (mm)”. Additionally, the delivery plan generating unit  123  receives from the specification selecting unit  122 , the data indicating that the specification of the electrode plate identified by the electrode plate ID “a101” is selected. Accordingly, the delivery plan generating unit  123  generates a web page as shown in  FIG. 6  that shows a delivery plan that presents to the client: the information “150 (mm)×150 (mm)×120 (mm)” that is the dimensions (height×depth×width) of the manufacturing machine of slightly acidic hypochlorous acid water determined by an arbitrary formula based on the information “12 (plate)” that is the number of electrode plates of the electrolytic cell with the specification using the electrode plate identified by the electrode plate ID “a101”, and the dimensions (height×depth×width) “50 (mm)×50 (mm)×40 (mm)” of the electrolytic cell with the specification using the electrode plate identified by the electrode plate ID “a101”; the information “800000 (yen)” that indicates the price of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cell, which is determined by an arbitrary formula based on the price “235000 (yen)” of the electrolytic cell with the specification using the electrode plate identified by the electrode plate ID “a101”; and the information “365 (day/time)” that is the estimated frequency of maintaining the manufacturing machine of slightly acidic hypochlorous acid water (S 111 ). Then, the delivery plan generating unit  123  outputs to the delivery plan data output unit  124 , the web page showing the delivery plan generated in this manner. 
     Then, upon receiving from the required condition data entry unit  113 , data indicating the IP address of the client  140 , and receiving from the delivery plan generating unit  123 , the web page showing the delivery plan, the delivery plan data output unit  124  outputs to the IP address of the client  140 , the web page showing the delivery plan.

Thus, the client can obtain the delivery plan presenting the specification of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cell having the configuration suitable to that condition. 
     Additionally, according to the delivery plan presenting system  100 , when the client buys the manufacturing machine of slightly acidic hypochlorous acid water, if the client further requires that the dimensions of the manufacturing machine of slightly acidic hypochlorous acid water be smaller, the client transmits to the web server  110  using the client  140 , data indicating that requirement. Thus, the client can obtain the delivery plan presenting the specification of the manufacturing machine of slightly acidic hypochlorous acid water including the electrolytic cell having the configuration suitable to that condition. 
     Further, according to the delivery plan presenting system  100 , when the client buys the manufacturing machine of slightly acidic hypochlorous acid water, if the client further requires that the lifetime of the manufacturing machine of slightly acidic hypochlorous acid water be longer, the client transmits to the web server  110  using the client  140 , data indicating that requirement.

     The delivery plan presenting system  100  can be effectively utilized in various business fields. For example, regarding ships, there are various classes, such as large and small ships, and various processing amounts of ballast water. Regarding newly built ships, it is possible to provide, from a design process, a large manufacturing machine of slightly acidic hypochlorous acid water, as a manufacturing machine of slightly acidic hypochlorous acid water for sterilizing ballast water. Regarding existing ships, however, it is difficult to provide a large manufacturing machine of slightly acidic hypochlorous acid water. For this reason, in such as case, the delivery plan presenting system  100 , which can design a manufacturing machine of slightly acidic hypochlorous acid water suitable to an installation space, is effective means. 
     Additionally, it is provided by the Water Supply Act in Japan that chlorine be used to sterilize clean water. Recently, there is a case where some municipality emphasizes the number of bacteria in sewage water. To sterilize clean water and sewage water, it is desirable to introduce a manufacturing machine of slightly acidic hypochlorous acid water, but there are various processing capabilities required by each municipality. For this reason, in such a case, the delivery plan presenting system  100 , which can design a manufacturing machine of slightly acidic hypochlorous acid water suitable to a required capability, is effective means. 
     Further, in plant factories, the amount of slightly acidic hypochlorous acid water to be used varies depending on crops to be cultivated. For this reason, in such a case, the delivery plan presenting system  100 , which can design, for each crop to be cultivated, a manufacturing machine of slightly acidic hypochlorous acid water suitable to a required capability, is effective means. 
       FIG. 8  illustrates an example of a hardware configuration in a case where the web server  110  is constituted by an electronic information processing device, such as a computer. The web server  110  includes: a CPU (central processing unit) peripheral unit; an input output unit; and a legacy input output unit. The CPU peripheral unit includes: a CPU  902 ; a RAM (random access memory)  903 ; a graphic controller  904 ; and a display device  905 , which are mutually connected by a host controller  901 . The input output unit includes: a communication interface  907 ; a hard disk drive  908 ; and a CD-ROM (compact disc read only memory) drive  909 , which are connected to the host controller  901  via an input output controller  906 . The legacy input output unit includes: a ROM (read only memory)  910 ; a flexible disk drive  911 ; and an input output chip  912 , which are connected to the input output controller  906 . 
     The host controller  901  connects the RAM  903 , the CPU  902  that accesses the RAM  903  at a high transfer rate, and the graphic controller  904 . The CPU  902  operates based on programs stored in the ROM  910  and the RAM  903 , and controls each unit. The graphic controller  904  obtains image data that the CPU  902  or the like generates in a frame buffer included in the RAM  903 , and displays the obtained image data on the display device  905 . Alternatively, the graphic controller  904  may include a frame buffer that stores image data generated by the CPU  902  or the like. 
     The input output controller  906  connects the host controller  901 , the hard disk drive  908  that is a relatively high-speed input output device, the communication interface  907 , and the CD-ROM drive  909 . The hard disk drive  908  stores programs and data to be used by the CPU  902 . The communication interface  907  accesses a network communication device  991  and transmits and receives a program or data. The CD-ROM drive  909  reads a program or data from the CD-ROM  992 , and outputs the program or data to the hard disk drive  908  and the communication interface  907  via the RAM  903 . 
     Relatively low-speed input output devices, such as the ROM  910 , the flexible disk drive  911 , and the input output chip  912  are connected to the input output controller  906 .

The flexible disk drive  911  reads the program or data from the flexible disk  993 , and outputs the program or data to the hard disk drive  908  and the communication interface  907  via the RAM  903 . The input output chip  912  connects various input output devices via the flexible disk drive  911 , a parallel port, a serial port, a keyboard port, a mouse port, or the like. 
     The program to be executed by the CPU  902  is stored in a recording medium, such as the flexible disk  993 , the CD-ROM  992 , or an IC (integrated circuit) card, and is provided by a user. The program stored in the recording medium may be compressed or uncompressed. The program is installed from the recording medium to the hard disk drive  908 , is read by the RAM  903 , and is executed by the CPU  902 . The program to be executed by the CPU  902  causes the web server  110  to function as: the electrode plate information data storage unit  111 ; the maintenance contractors information data storage unit  112 ; the required condition data entry unit  113 ; the required amount calculating unit  114 ; the maintenance frequency specifying unit  115 ; the total operating time calculating unit  116 ; the lifetime evaluation unit  117 ; the generated amount calculating unit  118 ; the calculating unit of the number of electrode plates  119 ; the price calculating unit  120 ; the dimensions calculating unit  121 ; the specification selecting unit  122 ; the delivery plan generating unit  123 ; and the delivery plan data output unit  124 , which have been explained with reference to  FIGS. 1 to 7 . 
     The above program may be stored in an external recording medium. Other than the flexible disk  993  and the CD-ROM  992 , an optical recording medium such as a DVD (digital versatile disc) or a PD (phase disk), a magnet-optical recording medium such as MD (mini disc), a semiconductor memory such as a tape medium or an IC card, may be used as the recording medium. Additionally, a recording medium, such as a hard disk or a RAM provided in a server system connected to a dedicated communication network or the Internet, may be used as the recording medium, thereby providing the delivery plan presenting system  100  as a program via the network.
