Description:
FIELD OF THE INVENTION 
   The present invention relates to methods of controlling costs, and more particularly, to a method of controlling costs applied to a circuitry designing stage for making electronic products. 
   BACKGROUND OF THE INVENTION 
   Typically, an entire production process of general electronic products involves several different stages starting from circuitry designing, configuration, error-elimination, testing, and test-production to mass production. During the process of developing each stage, the cost control greatly influences the profit and value of the fabricated products. In a highly competitive market nowadays, besides providing high-quality and multi-functional products to meet the consumers&#39; demands, how to effectively increase the gross profit is also imperative. Since circuitry designing is the primary and the most significant stage in a production process, the cost control of each electronic element chosen and used in a circuitry becomes crucial. Generally, the process of a latter stage in circuitry designing is depicted with reference to the accompanying drawings. 
   Illustrated in  FIGS. 1(A) and 1(B)  are a complete circuitry and the corresponding form thereof. As shown in  FIG. 1(A) , an engineer uses a drawing software to draw and complete the circuitry, the drawing software further provides a selecting function for the engineer to select a number of elements for composing the circuitry via a material-selection form (linked to an element database through the drawing software) displayed on a screen as shown in  FIG. 1(B) . Thereafter, the engineer chooses necessary and appropriate elements for completing circuitry designing from the given columns on the material-selection form that includes element packaging, properties, factory materials, and specifications, thereby conducting subsequent processes of production accordingly. Then, an internal accounting department calculates the total cost of the elements used for the circuitry based on the unit price of each electronic element chosen by the engineer. 
   As seen from the above, there is no cost control mechanism used in the foregoing circuitry designing stage. The entire process is simply conducted by an engineer selecting the electronic elements as required according to the information given on the columns of a material selection form, and an accounting department calculating the total cost according to the pricing data of each of the elements chosen by the engineer. In the process, an engineer only chooses the specifications for required elements and is unable to assist in controlling the costs, resulting low product profit and weak competition in the market as a result. 
   Therefore, how to effectively control the cost of each of the elements used in a circuitry designing stage of a production process to thereby increase product profits and market competition, is a critical issue to solve. 
   SUMMARY OF THE INVENTION 
   A primary objective of the present invention is to provide a method for controlling an optimal cost, which can be applied to a circuitry designing process for making electronic products, thereby saving the cost and increasing the profit as a result. 
   Another objective of the present invention is to provide a method of controlling an optimal cost, which can be applied to a circuitry designing process for making electronic products, thereby enhancing the market competition ability. 
   According to the above and other objectives, the present invention proposes a cost-optimization method, the method comprising the steps of: integrating data of elements of identical specification but with different unit prices to form an element database; and, choosing each of the required elements for drawing a circuitry according to the data stored in the element database. 
   Compared to the circuitry designing used in the prior art, the cost-optimization method of the present invention is beneficial to implement in that the method provides an element database capable of storing and displaying electronic elements of identical specification but with different unit prices, allowing the users to select appropriate elements as required, so that a primary objective of effectively controlling an optimal cost can be achieved.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     FIG. 2  illustrates the major steps involved in proceeding the cost-optimization method of the invention. It is to be noted that, the schematic drawings are simplified to depict only the basic steps involved in proceeding the method of the invention, therefore the drawings only depict words that are related to the invention for brevity. 
   As shown in the drawing, the cost optimization method of the invention is applied to a circuitry designing stage for making electronic products, allowing a user in drawing a circuitry to choose elements of identical specification but with different unit prices, thereby achieving the objective of an optimal cost. 
   First, a step S 10  is implemented to integrate data of each of the electronic elements of identical specification but different unit prices to form an element database. This is implemented by first categorizing each of the electronic elements to sort out elements of identical specification with different unit prices so as to form an element database for proceeding the subsequent steps. Thereafter, a step S 11  is proceeded. 
   In step S 11 , each of the required elements is chosen for composing a circuitry according to the element database, wherein a user chooses a most suitable element according to the data displayed from the database for completing the circuitry designing process, as shown in.  FIG. 3(A) , which exemplifies an element chosen for a circuitry, wherein a user chooses the required elements for drawing a circuitry by using a drawing software that is prompted to link to the foregoing database and is shown by a form for the user&#39;s selection; illustrated in  FIG. 3(B)  is an exemplar of the aforementioned form, wherein after a user selects an element, a material-selection form is displayed on a screen having columns including name of element, mode of packaging, property of element, material serial number of factory, specification of element, source of incoming materials, and unit price of element (the columns displayed can be set according to the user&#39;s requirements), wherein the column of unit price of element is provided so that the user can choose the most suited ones based on budget factors. Thereafter, a step S 12  is implemented. 
   In step S 12 , a total cost for the finished circuitry is calculated. This step is implemented using the aforementioned drawing software so that the user can evaluate and control the cost accordingly.  FIG. 4(A)  illustrates an exemplary circuitry in that after a user completes selection of all required elements, information relating to the circuitry is displayed on a screen and presented by means of a form via the drawing software;  FIG. 4(B)  illustrates an exemplary form, wherein the displayed information including columns of material serial number of factory, mode of packaging, quantity of element, unit price of element, cost of element, total quantity of element and total cost of element (the columns displayed can be set according to the user&#39;s requirements), wherein the column of unit price of element is provided for users&#39; consideration based on budget factors. If the user considers the total cost of the chosen elements for a circuitry is too high, the user may reselect each composing element of lower unit prices, thereby achieving the objective of controlling an optimal cost in a circuitry designing process. 
     FIG. 5  illustrates the major steps for proceeding another embodiment of the cost optimization method of the invention. Similarly, the steps in proceeding the cost optimization method of the invention is applied to a circuitry designing process for making electronic products, allowing a user in drawing a circuitry to choose elements of identical specification but different unit prices, thereby achieving the objective of the optimal cost. 
   First, a step S 20  is implemented to integrate data of each electronic element of identical specification but different unit prices to form an element database. Similar to the step S 10  shown in  FIG. 2 , this step is to first categorize each electronic element to sort out elements of identical specification but different unit prices so as to form an element database for proceeding the subsequent steps. Thereafter, step S 21  is proceeded. 
   In step S 21 , the circuitry sets a budget cost value which is inputted into the drawing software by manual setting to serve as a cost control mechanism according to the budget considerations in circuitry designing for making electronic products. Thereafter, step S 22  is proceeded. 
   In step S 22 , each of the required elements is chosen for drawing a circuitry according to the element database. This step is implemented in a way similar to the step S 11  in  FIG. 2 , wherein a user chooses a most suitable element according to the data displayed from the database for completing the circuitry designing process. Thereafter, step S 23  is proceeded. 
   In step S 23 , a total cost for making the circuitry is calculated based on the unit price of each of the elements chosen for the circuitry via the circuitry drawing software. Thereafter, step S 24  is proceeded. 
   In step S 24 , the total cost of the circuitry is compared to the budget cost value, wherein the aforementioned drawing software compares the total cost with the aforementioned budget value to see if the total sum of each unit price of the chosen elements added up together is larger than the inputted budget value, and, if yes, step S 25  is entered; or else, step S 26  is proceeded. 
   In step S 25 , each of the elements of identical specification but different prices is chosen for drawing the circuitry according to the element database, wherein the total cost is deemed cost-ineffective to implement if the sum is larger than the inputted budget cost value, in such an instance, the drawing software displays a message on a screen to remind the user so that a new circuitry can be depicted by the user using elements of identical specification but at lower cost according to the information displayed from the element database, thereby completing the circuitry designing process. Thereafter, step S 23  is returned to recalculate the total cost and make comparisons. 
   In step S 26 , the finished circuitry is stored if the total cost of the circuitry is smaller or equivalent to the inputted budget cost value, which means it is cost-effective to implement, the drawing software proceeds to store all data of chosen elements for the circuitry so as to proceed with subsequent production process and achieve the objective of an optimal cost accordingly. 
     FIG. 6  illustrates the major steps for proceeding another preferred embodiment of the cost optimization method of the invention. Similarly, the steps in proceeding the cost optimization method of the invention is applied to a circuitry designing process for making electronic products, allowing a user in drawing a circuitry to choose elements of identical specification but different unit prices, thereby achieving the objective of an optimal cost. 
   First, a step S 30  is implemented to integrate data of each electronic element of identical specification at different unit prices to form an element database. Similar to the step S 10  shown in  FIG. 2  and the step S 20  in  FIG. 5 , this step is first to categorize the electronic elements to sort out elements of identical specification but different unit prices so as to form an element database for proceeding the subsequent steps. 
   In step S 31 , each of the required elements is chosen for drawing the circuitry according to the element database. This step is implemented in a way similar to the step S 11  in  FIG. 2  and the step S 22  of  FIG. 5 , wherein a user chooses a most suitable element according to the data displayed by the element database for completing the circuitry designing process. Thereafter, step S 32  is proceeded. 
   In step S 32 , each electronic element of identical specification but different unit prices is chosen for drawing at least one referral circuitry. This step is implemented using the drawing software to choose elements of identical specification but different unit prices according to the element database and the circuitry drawn by the user. The specification of the elements used in the referral circuitry is the same as the foregoing circuitry but with different, i.e. lower unit prices. Therefore, since there is a plurality of elements with different unit prices, a plurality of referral circuitry is formed with different unit prices. Thereafter, step S 33  is proceeded. 
   In step S 33 , a total cost for the circuitry is calculated based on the unit price of each of the elements chosen in the foregoing circuitry via the circuitry drawing software. Thereafter, step S 34  is proceeded. 
   In step S 34 , a total cost for the referral circuitry is calculated based on the unit price of each of the elements chosen for the circuitry via the circuitry drawing software. If there is a plurality of referral circuitry, a plurality of the total cost for each of the referral circuitry will be generated. Thereafter, step S 35  is proceeded. 
   In step S 35 , the total cost is compared to the total referral cost, wherein the aforementioned drawing software compares the total cost with the aforementioned referral total cost to see if the total sum of each unit price of the chosen elements added up together is larger than the foregoing referral total cost, and, if yes, step S 36  is entered; or else, step S 37  is proceeded. 
   In step S 36 , the referral circuitry is stored if the total cost is smaller or equivalent to the total referral value which is calculated using the drawing software according to the element database and the circuitry drawn by the user, which means it is cost-effective to implement, the drawing software then proceeds to store all data of chosen elements for the referral circuitry so as to proceed with subsequent production process, thereby achieving the objective of an optimal cost accordingly. In other words, the method is implemented using elements of identical specification with different prices, i.e. at lower cost, so as to complete circuitry designing and achieve an optimal cost.
