     DESCRIPTION OF EMBODIMENTS 
     Embodiments 
     Hereinafter, a guidance information presentation system according to an embodiment of the present invention will be described with reference to  FIGS. 1 to 11 . 
       FIG. 1  is a schematic block diagram showing a configuration example of a guidance information presentation system in the embodiment of the present invention. The guidance information presentation system  1  is a system for providing various guidance information to staff of an operation organization that manages a plant according to a state of the plant to be operated, a department to which the staff of the operation organization belongs, or the like. The guidance information is, for example, technical information such as predictive detection of occurrence of trouble and a method of coping with the trouble that occurs, management information such as a daily profit and a cost reduction method, information about maintenance such as a wearing condition of components and a maintenance plan therefor, and the like. In addition to the above guidance information, the guidance information presentation system  1  of the present embodiment also presents guidance information related to persons such as guidance about educational services suitable for each staff member and advice about reconsideration of a personnel composition of the operation organization. The guidance information presentation system  1  of the present embodiment supports the operation of the plant functioning as a social infrastructure for several decades by providing guidance information for supporting the operation of the plant from various aspects throughout the plant&#39;s life cycle. 
     The guidance information presentation system  1  is configured to include a plant  100 , a guidance information presentation device  10 , a maintenance department terminal device  20 , an operation department terminal device  21 , a technical department terminal device  22 , and a management department terminal device  23 . The guidance information presentation device  10  is connected to each of a plant device  100 A, a plant device  100 B, the maintenance department terminal device  20 , the operation department terminal device  21 , the technical department terminal device  22 , and the management department terminal device  23  so that the guidance information presentation device  10  can communicate therewith. A plant to be operated other than the plant  100  may be present. 
     The plant  100  is, for example, a power generation plant with a gas turbine combined cycle. Plant devices  100 A,  100 B, and the like are installed in the plant  100 . The plant devices  100 A and  100 B are, for example, gas turbines. The plant  100  transmits operation data such as output values and rotational speeds of the plant devices  100 A and  100 B to the guidance information presentation device  10 . 
     The guidance information presentation device  10  outputs guidance information to the department terminal devices  20  to  23 . The plant device installed in the power generation plant has a life cycle and its role and usage change while the plant device is used for many years. Staff of a management organization needs to apply appropriate maintenance and improvement according to the change. The guidance information presentation device  10  generates the guidance information according to an operation situation of the plant device  100 A, a role of each department related to the operation of the plant  100 , and the like on the basis of the operation data acquired from the plant device  100 A. 
     The maintenance department terminal device  20  is an information processing device such as a personal computer (PC) provided in the maintenance department. The staff of the maintenance department performs periodic inspection or maintenance work on the plant device. 
     The operation department terminal device  21  is an information processing device such as a PC provided in the operation department. The staff in the operation department conducts business related to a plant operation such as monitoring of a plant state, starting/stopping of a plant device, and a change in a target output value. 
     The technical department terminal device  22  is an information processing device such as a PC provided in the technical department. The staff of the technical department has expert knowledge and skills, makes various determinations from technical points of view, and solves problems that cannot be solved by the operation department or the maintenance department. 
     The management department terminal device  23  is an information processing device such as a PC provided in the management department. Staff in the management department will consider economic efficiency and profitability, personnel planning and power generation planning, cost reduction planning, and the like. 
     When the guidance information presentation device  10  generates the guidance information used by the staff of the maintenance department, the guidance information presentation device  10  transmits the guidance information to the maintenance department terminal device  20 . The same applies to other departments. 
       FIG. 2  is a schematic block diagram showing a configuration example of the guidance information presentation device in the embodiment of the present invention. 
     As shown in  FIG. 2 , the guidance information presentation device  10  includes an operation data collection unit  101 , an operation time calculation unit  102 , a number-of-starts calculation unit  103 , an operation mode determination unit  104 , an operation state determination unit  105 , an operation organization information acquisition unit  106 , a calculation unit  107 , a lecture attendance information acquisition unit  108 , a trouble information acquisition unit  109 , an organization information comparison unit  110 , a guidance information presentation unit  111 , and a storage unit  112 . The guidance information presentation device  10  includes computers such as one or more server terminal devices. 
     The operation data collection unit  101  acquires operation data transmitted by the plant  100  and records the operation data in the storage unit  112 . 
     The operation time calculation unit  102  calculates an operation time of the plant device  100 A on the basis of the operation data. 
     The number-of-starts calculation unit  103  calculates the number of starts of the plant device  100 A on the basis of the operation data. 
     The operation mode determination unit  104  identifies a life stage of the plant device  100 A or the like (a gas turbine or the like) provided in the plant  100  on the basis of the operation data. In the life stage, for example, “Base Load”, “Intermediate”, and “Peaker” are present in accordance with a maturity level. “Base Load” refers to a period during which the plant device operates as a central power generation device that covers power demand from the start of an operation of the plant device. In the life stage of “Base Load”, the plant device  100 A is in operation all the time. Hereinafter, the life stage “Base Load” is referred to as a golden stage. “Intermediate” refers to a period of a transition stage for a new model in which the plant device passing through the golden stage is operated weekly or daily. Hereinafter, the life stage “Intermediate” is referred to as the transition stage. “Peaker” refers to a period until disposal is reached after switching to a new model. During this period, the plant device  100 A is solely operated in a case in which power is insufficient or the like. Hereinafter, the life stage “Peaker” is referred to as a decline stage. The operation mode determination unit  104  determines the life stage of the plant device  100 A on the basis of an operation time of the plant or an operation time and the number of starts of the plant device  100 A. 
     The operation state determination unit  105  determines the operation state of the plant device  100 A on the basis of the operation data. The determination of the operation state is a determination of whether or not the plant device  100 A is in operation or whether the plant device  100 A is in a state before start, a state in operation, or a state after an operation. 
     The operation organization information acquisition unit  106  acquires information about the department or staff of a destination to which the guidance information is presented. The information about the staff includes, for example, information such as a name, the number of years of experience in the department, and qualifications held. 
     The calculation unit  107  performs various calculation, analysis, and analysis processes related to the provision of the guidance information. For example, the calculation unit  107  performs simulation of profit planning for the management department. Alternatively, the calculation unit  107  creates a predictive detection model by machine learning for the operation department. Alternatively, the calculation unit  107  performs risk analysis on the plant state for the maintenance department. In addition, although various calculations, analyses, and the like are required for generating the guidance information and the calculation unit  107  is implemented as a program module for each process, the calculation unit  107  has all functions thereof in the present embodiment. 
     The lecture attendance information acquisition unit  108  acquires lecture attendance history information about the educational service related to the operation of the plant  100  for which staff of each of the maintenance department, the operation department, the technical department, and the management department has attended a lecture. 
     The trouble information acquisition unit  109  acquires trouble information generated in the plant  100 . 
     The organization information comparison unit  110  acquires information about an operation organization of another plant and compares the acquired information with information about an operation organization of a current plant. The current plant is a plant (the plant  100  in the present embodiment) that is a target from which the guidance information presentation device  10  acquires operation data. 
     The guidance information presentation unit  111  generates guidance information according to the life stage, the operation state, and member information of the plant  100  and outputs the generated guidance information to a terminal device (the maintenance department terminal device  20  or the like) of each department. 
     The storage unit  112  stores various information. 
       FIG. 3  is a flowchart showing an example of a process of the guidance information presentation device in the embodiment of the present invention. 
     A process of presenting the guidance information related to the plant device  100 A will be described with reference to  FIG. 3 . First, the operation data collection unit  101  collects operation data of the plant device  100 A from the plant  100  and records the collected operation data in the storage unit  112  (step S 11 ). Next, the operation mode determination unit  104  determines a life stage of the plant device  100 A (step S 12 ). Specifically, the operation mode determination unit  104  determines whether the plant device  100 A is in a golden stage, a transition stage, or a decline stage. Details of a life stage determination method will be described below with reference to  FIGS. 4 and 5 . The operation mode determination unit  104  outputs information about the determined life stage to the guidance information presentation unit  111 . Next, the operation state determination unit  105  determines a current operation state of the plant device  100 A (step S 13 ). For example, the operation state determination unit  105  reads operation data such as a latest output value and a rotational speed of the plant device  100 A recorded in the storage unit  112  and determines that the plant device  100 A is in operation if these values are greater than or equal to a predetermined value (for example, 0). If a value such as the read output value is less than or equal to the predetermined value, the operation state determination unit  105  determines that the operation of the plant device  100 A is stopped. Further, when it is determined that the operation is stopped, for example, the operation state determination unit  105  refers to operation plan information pre-recorded in the storage unit  112 , determines that the plant device  100 A is in a state after an operation if a current clock time is within a predetermined time from the stopping of the operation, and determines that the plant device  100 A is in a state before the operation if the current clock time is within the predetermined time retroactively from a scheduled start time defined in the operation plan information. The operation state determination unit  105  outputs information about the determined operation state to the guidance information presentation unit  111 . 
     Next, the operation organization information acquisition unit  106  acquires information about the department for which the guidance information is presented (step S 14 ). For example, title information indicating types and details of information to be output to the department terminal devices  20  to  23  according to each life stage and each operation state of the plant device  100 A is pre-recorded in the storage unit  112 , and the operation organization information acquisition unit  106  reads and acquires information about a department to which guidance information is output and types and details of guidance information to be output to the department on the basis of the information. The operation organization information acquisition unit  106  outputs information in which a presentation destination (department) and the guidance information to be presented are associated with each other to the guidance information presentation unit  111 . Next, the guidance information presentation unit  111  presents guidance information corresponding to a life stage, an operation state, and a presentation destination department of the plant device  100 A (step S 15 ). An example of the guidance information is described below. 
     &lt;When Operation State is State Before Operation&gt; 
     1. Example of Guidance Information for Maintenance Department 
     For example, in the storage unit  112 , information indicating “additional tightening of bolts of a part XX” is pre-recorded as guidance information to be presented to the plant device  100 A in all the life stages. On the basis of this record, the guidance information presentation unit  111  outputs guidance information such as “Please tighten up bolts of a part XX again” to the maintenance department terminal device  20 . 
     For example, ideal setting values for performing an efficient operation for setting items according to, for example, each life stage and each operation environment (an outside air temperature or the like) are recorded in the storage unit  112 . The guidance information presentation unit  111  reads the setting values according to the life stage determined in step S 12  and the operation data (the outside air temperature or the like) collected from the plant  100  and outputs guidance information for prompting the staff to set ideal setting values in the setting items to the maintenance department terminal device  20 . 
     For example, when a presentation destination department and a type of guidance information to be presented acquired from the operation organization information acquisition unit  106  are a “maintenance department” and “advanced risk analysis”, the guidance information presentation unit  111  instructs the calculation unit  107  to perform the advanced risk analysis. Then, for example, a program having the function of the advanced risk analysis included in the calculation unit  107  performs risk analysis according to the life stage using a well-known risk analysis technique using operation data during a previous operation stored in the storage unit  112 , information about an inspection result of inspection work performed by the maintenance department after the operation, or the like. The guidance information presentation unit  111  outputs a result of risk analysis by the calculation unit  107  to the maintenance department terminal device  20 . Likewise, on the basis of an instruction of the guidance information presentation unit  111 , the calculation unit  107  may predict a lifespan of a part of the plant device  100 A and analyze a part to be replaced and the guidance information presentation unit  111  may output prediction and analysis results to the maintenance department terminal device  20 . Staff of the maintenance department can view the guidance information and perform maintenance work before the operation. 
     2. Example of Guidance Information for Operation Department 
     For example, when a presentation destination department and a type of guidance information to be presented acquired from the operation organization information acquisition unit  106  are an “operation department” and an “optimum start sequence”, the guidance information presentation unit  111  instructs the calculation unit  107  to automatically create the optimum start sequence. Then, a program having a function of automatically creating the optimum start sequence included in the calculation unit  107  creates a start sequence with highest efficiency in, for example, a load band according to the life stage (for example, a rated load in the golden stage, a load lower than that during the other periods, or the like). The guidance information presentation unit  111  outputs optimum start sequence information to the operation department terminal device  21 . The staff of the operation department can view the guidance information and start the plant device  100 A in the optimum sequence. 
     The guidance information presentation unit  111  may output the guidance information to be output to the maintenance department terminal device  20  and the operation department terminal device  21  also to the technical department terminal device  22 . The staff of the technical department can check the guidance information and check whether or not the guidance information is appropriate from a technical point of view. 
     3. Example of Guidance Information for Management Department 
     On the basis of an instruction of the guidance information presentation unit  111 , the calculation unit  107  performs simulation such as a cost reduction measure (for example, a procurement method of suppressing a fuel cost or the like), staff planning of the operation department (a staff arrangement capable of performing an operation with as few people as possible in accordance with a power generation plan), or profit planning (for example, prediction of a bid price of power, calculation of a profit, and the like) in a calculation method according to the life stage. The guidance information presentation unit  111  outputs a simulation result to the management department terminal device  23 . Staff of the management department can view the guidance information and perform cost reduction, an appropriate staff arrangement, profit prediction, and the like. 
     &lt;When Operation State is State in Operation&gt; 
     1. Example of Guidance Information for Maintenance Department 
     The calculation unit  107  determines important inspection items to be inspected at the next regular inspection on the basis of operation data collected by the operation data collection unit  101  according to an instruction of the guidance information presentation unit  111 . At this time, the calculation unit  107  may set different items in accordance with the life stage as inspection items. For example, the calculation unit  107  determines that there is an inspection item in relation to an item in which a value close to an abnormal value is output from among operation data items. The guidance information presentation unit  111  outputs information about the important inspection items to the maintenance department terminal device  20 . 
     2. Example of Guidance Information for Operation Department 
     The calculation unit  107  performs predictive detection of trouble according to an instruction from the guidance information presentation unit  111 . Specifically, in a predictive detection function provided in the calculation unit  107 , a probability of occurrence of trouble indicated by latest operation data collected by the operation data collection unit  101  is calculated on the basis of a predictive detection model generated by machine learning and it is determined that there is a possibility of occurrence of trouble when a probability of occurrence is greater than or equal to a threshold value. At this time, the calculation unit  107  may switch the predictive detection model in accordance with the life stage. The guidance information presentation unit  111  outputs guidance information such as a high possibility of occurrence of trouble, details of the trouble, a prevention method and the like to the operation department terminal device  21 . When trouble actually occurs, the guidance information presentation unit  111  outputs guidance information, such as a method of coping with the trouble that has occurred, to the operation department terminal device  21 . 
     A cause of trouble and a method of coping with the trouble for each life stage are recorded in the storage unit  112  and the guidance information presentation unit  111  may output the method of coping with the trouble for each life stage at the time of occurrence of trouble. For example, when the stopping of the plant device  100 A is detected, there is a possibility that an excessive thermal load due to frequent repetition of starting/stopping may be one cause if the life stage is the transition stage. In this case, the guidance information presentation unit  111  outputs information (a cause) and a countermeasure method for a portion of a high possibility of destruction or failure due to a thermal load to the operation department terminal device  21 . Alternatively, if the life stage is the decline stage, there is a possibility of stopping because it is not possible to perform a normal operation due to rust according to stopping for a long period. In this case, the guidance information presentation unit  111  outputs information (a cause) or a countermeasure method for a portion where rusting is likely to occur to the operation department terminal device  21 . 
     The cause of the trouble and the guidance information about the method of coping with the trouble may also be output to the maintenance department terminal device  20  and the technical department terminal device  22 . The staff of the maintenance department and the technical department can cooperate and cope with the trouble. 
     &lt;When Operation State is State after Operation&gt; 
     1. Example of Guidance Information for Maintenance Department 
     For example, the calculation unit  107  performs damage evaluation on parts of the plant device  100 A based on the operation data collected by the operation data collection unit  101  according to an instruction from the guidance information presentation unit  111 . The guidance information presentation unit  111  outputs guidance information indicating what part is consumed to what extent, necessity of exchange/maintenance work, and the like to the maintenance department terminal device  20 . 
     For example, information about an upgraded product that exerts an effect for each life stage is recorded in the storage unit  112 . For example, if the life stage is the transition stage, the number of starts/stops increases as compared to the golden stage. An operation at a load less than the rated load may be required during the transition stage. In the storage unit  112 , information about upgraded products for shortening a start time and information about upgraded products capable of being operated efficiently even with a small load are recorded in association with the life stage “transition stage”. In the storage unit  112 , information about upgraded products contributing to stable operation (for improving reliability) is recorded in association with the life stage “golden stage”. The guidance information presentation unit  111  outputs information about upgraded products according to the life stage determined in step S 12  or guidance information including a merit in the case of upgrading to the maintenance department terminal device  20 . Staff of the maintenance department will consider application planning of upgraded products with reference to the guidance information. 
     2. Example of Guidance Information for Operation Department 
     For example, a result (an actual value) of the optimum start sequence created before the operation is recorded in the storage unit  112 . The guidance information presentation unit  111  outputs the actual value to the operation department terminal device  21  as guidance information for prompting the staff to perform a process retrospective on a current operation. 
     In the exemplary example of a maintenance department, the guidance information presentation unit  111  outputs information about upgraded products and the like according to the life stage as guidance information to the operation department terminal device  21 . The staff of the operation department will consider the introduction of upgraded products with reference to the guidance information. 
     3. Examples of Guidance Information for Technical Department 
     For example, information about upgraded products according to the life stage and information indicating technical requirements for introducing the upgraded products are recorded in the storage unit  112 . The guidance information presentation unit  111  outputs information about upgraded products according to the life stage determined in step S 12  and guidance information including technical requirements necessary for the introduction to the technical department terminal device  22 . The staff of the technical department views the guidance information and considers whether or not the introduction into a plant of a current company is possible. 
     4. Example of Guidance Information for Management Department 
     For the above-described upgraded products, the guidance information presentation unit  111  reads information indicating an upgraded product, an introduction cost, and an economic benefit after introduction (information indicating that a cost can be reduced by X yen at the time of unplanned stopping because a more stable operation can be performed and the like) according to the life stage determined in step S 12  from the storage unit  112  and outputs the read information as guidance information to the management department terminal device  23 . The staff of the management department views the guidance information and considers the introduction of upgraded products into the plant of the current company. 
     The calculation unit  107  analyzes bid competitiveness and electric power demand from information about a power sales record in the current operation and the guidance information presentation unit  111  outputs analysis results as guidance information to the management department terminal device  23 . Also, in this case, the calculation unit  107  may switch an analysis method in accordance with the life stage. The staff of the management department views the guidance information and considers the next power generation plan. 
     According to the guidance information presentation system of the present embodiment, it is possible to provide the guidance information as described above suitable for the life stage and the operation state of the plant device  100 A by combining real-time operation data of the plant  100  and departments of the operation organization. Because the guidance information about details suitable for business is presented for each department, it is possible to provide guidance information according to needs of the staff of each department. By creating information about know-how and the like relying on experience so far to perform an operation and automatically presenting the created information, for example, the staff of the operation department with less experience can safely operate the plant. By presenting guidance information suitable for a situation of the plant, it is possible to efficiently operate the plant. 
     Next, the life stage determination method in step S 12  of the flowchart of  FIG. 3  will be described. 
       FIG. 4  is a diagram showing a life stage determination process in an embodiment of the present invention. 
     In  FIG. 4 , a vertical axis represents the number of starts (the number of times/year), and a horizontal axis represents an operation time (an operation time/year). A graph of  FIG. 4  shows a relationship of the life stage, the number of starts, and the operation time of the plant device  100 A. For example, the operation time is shortened in the decline stage (“Peaker” in the drawing) and the number of starts is small and the operation time is long in the golden stage (“Base Load” in the drawing). In the transition stage (“DSS” and “WSS” in the drawing), the operation time is longer than that in the decline stage and the number of starts is larger than that in the decline stage. DSS is an operation mode in which starting/stopping is performed on a daily basis, and WSS is an operation mode in which starting/stopping is performed on a weekly basis (stop on the weekends). Using the above-described properties of each life stage, the operation mode determination unit  104  determines the life stage of the plant device  100 A. 
       FIG. 5  is a first flowchart showing an example of a life stage determination process in the embodiment of the present invention. 
     A first method of the life stage determination process will be described with reference to  FIG. 5 . 
     First, the operation time calculation unit  102  calculates a total of operation times during a corresponding period from information such as a starting time and a stopping time included in operation data of the plant device  100 A during a predetermined period (for example, 1 year, 1 month, 6 months, or the like) recorded in the storage unit  112  (step S 21 ). The operation time calculation unit  102  outputs the total operation time to the operation mode determination unit  104 . Next, the operation mode determination unit  104  determines the life stage on the basis of the length of the operation time (step S 22 ). For example, the length of the operation time (a threshold value A) for distinguishing the transition stage and the decline stage with respect to the length of the above-described predetermined period and the length of the operation time (a threshold value B) for distinguishing the transition stage and the golden stage are predetermined (threshold value B&gt;threshold value A), and the operation mode determination unit  104  determines the life stage by comparing the total of the operation times calculated by the operation time calculation unit  102  with the threshold values (the threshold value A and the threshold value B). Specifically, when the total of the operation times is less than or equal to the threshold value A, the operation mode determination unit  104  determines that the life stage of the plant device  100 A is the decline stage. When the total of the operation times is greater than the threshold value A and less than the threshold value B, the operation mode determination unit  104  determines that the life stage of the plant device  100 A is the transition stage. When the total of the operation times is greater than or equal to the threshold value B, the operation mode determination unit  104  determines that the life stage of the plant device  100 A is the golden stage. 
     Next, another method of the life stage determination process will be described with reference to  FIG. 6 . 
       FIG. 6  is a second flowchart showing an example of a life stage determination process in the embodiment of the present invention. 
     First, the operation time calculation unit  102  calculates a total of operation times of the plant device  100 A during a predetermined period as in step S 21  (step S 31 ). The operation time calculation unit  102  outputs the total operation time to the operation mode determination unit  104 . Next, the operation mode determination unit  104  separates the decline stage from the other life stages on the basis of the length of the operation time. Specifically, the operation mode determination unit  104  determines whether or not the length of the operation time is less than or equal to the threshold value A (step S 32 ). Here, the threshold value A is the length of the operation time for distinguishing the decline stage and the transition stage as described with reference to  FIG. 5 . When the total of the operation times is less than or equal to the threshold value A (step S 32 ; Yes), the operation mode determination unit  104  determines that the life stage of the plant device  100 A is the decline stage (step S 33 ). 
     When the total of the operation times is greater than the threshold value A (step S 32 ; No), the number-of-starts calculation unit  103  calculates the number of starts of the plant device  100 A during a predetermined period (step S 34 ). For example, the number-of-starts calculation unit  103  calculates the number of starts during the period by aggregating information such as a start clock time included in the operation data of the plant device  100 A during the predetermined period recorded in the storage unit  112 . The number-of-starts calculation unit  103  outputs the calculated number of starts to the operation mode determination unit  104 . Next, the operation mode determination unit  104  calculates the number of starts per unit period (step S 35 ). Specifically, the operation mode determination unit  104  obtains the number of starts per unit period by dividing the number of starts calculated in step S 34  by the operation time calculated in step S 31 . Next, the operation mode determination unit  104  compares the calculated number of starts per unit period with the threshold value C (step S 36 ). As shown in  FIG. 4 , the life stage can be determined to be the transition stage when the number of starts per unit period is large and can be determined to be the golden stage when the number of starts per unit period is small. The threshold value C is a threshold value of the number of starts per unit period for distinguishing the transition stage and the golden stage. 
     When the number of starts per unit period is less than or equal to the threshold value C (step S 36 ; Yes), the operation mode determination unit  104  determines that the life stage of the plant device  100 A is the golden stage (step S 37 ). When the number of starts per unit period is greater than the threshold value C (step S 36 ; No), the operation mode determination unit  104  determines that the life stage of the plant device  100 A is the transition stage (step S 38 ). 
     The operation mode determination unit  104  determines the life stage of the plant device  100 A by the method described with reference to  FIGS. 4 to 6 . According to the present embodiment, it is possible to determine the life stage of the plant device  100 A or the like on the basis of operation data collected by the operation data collection unit  101 . Thereby, the guidance information presentation unit  111  can output guidance information according to the life stage to the department terminal devices  20  to  23 . The staff of each department can carry out business with reference to knowledge suitable for the life stage. 
     A case in which the guidance information presentation system  1  of the present embodiment presents guidance information according to a situation of the plant  100  or a department has been described above. However, there is a possibility that it is not possible to sufficiently prevent unplanned stopping or the like from occurring due to a mistake of an operation monitoring person with low proficiency by merely presenting the guidance information. Although human resource development is important to avoid trouble caused by proficiency levels of members, active engagement in human resource education is not carried out in many cases in the conventional plant operation organization. To solve such a problem, the guidance information presentation system  1  of the present embodiment presents guidance information for prompting the staff to attend a lecture of an educational service. More specifically, the guidance information presentation system  1  presents an appropriate educational service in conjunction with a role and an operation method of the plant device  100 A that changes in accordance with the life stage. 
       FIG. 7  is a diagram showing an example of a relationship between a generational change of staff in the plant and the life stage of the plant. 
     In  FIG. 7 , a horizontal axis represents a flow of time from an operation start to the disposal of the plant  100 , and a vertical axis represents a need level of necessity for an on-site educational service at that time. In  FIG. 7 , first to third generations show examples of generational changes according to replacement of a group of staff who work in the business of the operation department and the maintenance department during the same period at a typical cycle. First, the staff of the first generation is a staff involved in the operation from the start of an operation of the plant. Educational needs are high for some time from the start of the operation of the plant because there is no accumulation of knowledge in the operation organization and there is much that the staff does not know. For the majority of the period during which the first generation is involved, the life stage of the plant device  100 A is the golden stage. In the golden stage, the plant device  100 A is in operation all the time and a stable operation is required with little change in the operation state. In the case of the golden stage, when certain knowledge is accumulated for some time from the start of the operation of the plant, educational needs will decline because the stable operation becomes possible. When ten years have elapsed from the start of the operation, the second generation is newly added. Education needs will rise for the second generation who have just arrived because there is no knowledge of the plant  100 . After some time from the acquisition of knowledge on an operation in the golden stage by the second generation staff, the life stage of the plant device  100 A transitions to the transition stage. When the life stage transitions to the transition stage, it is necessary to master new knowledge or skills because the number of starts/stops of the plant device  100 A increases, a flexible operation is required when an operation load also takes various values, and the operation mode changes. Accordingly, even after the rise in the initial educational needs in the second generation stops, the educational needs will continue to be maintained at a certain level. When ten years have elapsed since the second generation joined, the third generation is newly added. In the third generation, educational needs will rise because there is no knowledge of the plant  100 . However, when the third generation arrives, the life stage of the plant device  100 A transitions to the transition stage and the role of the plant device  100 A is relatively lowered. Also, there is accumulation of know-how and the like accumulated in the operation of the past twenty years. Therefore, the educational needs when the third generation is added will not be higher than those at the beginning of the two generations in the past. After some time, the life stage of the plant device  100 A transitions to the decline stage. Education needs will also decline when the life stage transitions to the decline stage. 
     In this manner, the educational needs change dramatically due to an influence of the plant&#39;s life stage and the replacement of staff. As will be described below with reference to  FIG. 8 , the guidance information presentation system  1  presents guidance information for prompting the staff to attend a lecture of an appropriate educational service at a timing when education is considered to be required according to the life stage of the plant, the number of years of experience of the staff, or the like. 
     Meanwhile, even if the staff of the first to third generations exemplified above are engaged in the same plant device  100 A, a grounded ability required according to a business environment at that time is different. For example, considering the business environment during a period for some time from the start of the operation of the plant, basic knowledge and a grounded ability such as an ability to solve problems are required for the first generation because the experience of the entire operation organization is inadequate and knowledge is insufficient during the period. In the second generation after a series of know-how is accumulated and a technically stable operation becomes possible, creativity is required in addition to the grounded ability required for the first generation to strengthen the profit structure. In the business environment during a period in which the third generation is engaged, it is necessary to refrain from capital investment as much as possible and competently increase a profit while controlling risks. On the other hand, knowledge related to an operation of the plant is sufficiently accumulated. In such an environment, in the third generation, a grounded ability such as creativity and applied skills utilizing accumulated knowledge is required. The guidance information presentation system  1  presents guidance information for guiding the educational service which extends the required grounded ability for the staff of each generation. 
       FIG. 8  is a flowchart showing an example of a process of outputting guidance information for prompting the staff to attend a lecture of an educational service in an embodiment of the present invention. 
     First, the operation data collection unit  101  collects operation data of the plant device  100 A and records the collected operation data in the storage unit  112  (step S 41 ). Next, the operation mode determination unit  104  determines a life stage of the plant device  100 A (step S 42 ). A specific determination method is as described in the flowcharts of  FIGS. 5 and 6 . The operation mode determination unit  104  outputs information about the determined life stage to the guidance information presentation unit  111 . Next, the operation organization information acquisition unit  106  acquires information about staff to whom the guidance information is required to be presented (step S 43 ). For example, in the storage unit  112 , information such as the number of years of experience of the staff and qualifications held are recorded in association with account information about the staff. In the storage unit  112 , lecture attendance history information indicating a type of educational service of lecture attendance of the staff in association with the account information about the staff is recorded. On the other hand, for example, when the maintenance staff of the maintenance department uses the maintenance department terminal device  20 , his/her account information is input, and the account information is transmitted to the guidance information presentation device  10 . Using the transmitted account information, the operation organization information acquisition unit  106  reads and acquires information about the staff (the number of years of experience of the staff or the like) from the storage unit  112 . The operation organization information acquisition unit  106  outputs the acquired information about the staff to the guidance information presentation unit  111 . The lecture attendance information acquisition unit  108  reads and acquires the lecture attendance history information of the storage unit  112  using the transmitted account information (step S 44 ). The lecture attendance information acquisition unit  108  outputs the acquired attendance history information to the guidance information presentation unit  111 . 
     The guidance information presentation unit  111  outputs guidance information for prompting the staff to attend a lecture of the educational service according to a life stage, the information about the staff, and the lecture attendance history information (step S 45 ). An example of the guidance information is described below. 
     For example, if the number of years of experience of the staff included in the information about the staff is 0 and there is no lecture attendance history of an educational service, the guidance information presentation unit  111  presents guidance information for prompting the staff to attend a lecture of a basic educational service common to all the life stages and common to departments and a departmental-specific basic educational service. The basic education service common to the departments is, for example, a lecture that provide basic knowledge of gas turbines and peripheral devices, a lecture that provides knowledge on safety and risk management, or the like. 
     For example, the guidance information presentation unit  111  presents guidance information for prompting the staff to attend a lecture of the following educational service on the basis of the life stage determined in step S 42 , the department to which the staff belongs acquired in step S 43 , and the information about the lecture attendance history acquired in step S 44 . 
     &lt;When Operation is being Performed in Golden Stage&gt; 
     An educational service for “basic knowledge of a plant operation”, a “method of performing an operation without unplanned stopping”, a “method of solving common trouble”, and the like is presented for the staff of the operation department, an educational service for a “daily inspection method”, a “periodic inspection method”, and the like is presented for the staff of the maintenance department, an educational service for a “technical viewpoint of a periodic inspection”, “design philosophy”, and the like is presented for the staff of the technical department, guidance information for prompting the staff to attend a lecture of an educational service for a “periodic inspection management viewpoint”, a “capital investment/recovery optimization operation”, a “cost caused by trouble”, and the like for the management department is presented to staff who have not attended a lecture thereof. 
     &lt;When Operation is being Performed in Transition Stage&gt; 
     An educational service for “safe execution of frequent starting/stopping”, a “method of shortening a starting/stopping time”, and the like is presented to the staff of the operation department, an educational service for a “maintenance method for a high-temperature part that deteriorates due to continuation of heating/cooling”, a “method of applying an upgraded part”, and the like is presented to the staff of the maintenance department, and guidance information for prompting the staff to attend a lecture of an educational service for an “efficient operation with a new model” and the like for the management department is presented to staff who have not attended a lecture thereof. 
     &lt;When Operation is being Performed in Decline Stage&gt; 
     An “operation method of maintaining an asset value (extending a lifespan)” is presented to the staff of the operation department, a “maintenance method at the time of non-operation” is presented to the staff of the maintenance department, and guidance information for prompting the staff to attend a lecture of an educational service for a “method of making an operation plan in consideration of an external environment” and the like for the management department is presented to staff who have not attended a lecture thereof. 
     When an upgraded product is applied and a new device or function is added, the guidance information presentation unit  111  presents guidance information for prompting the staff to attend a lecture of an educational service that provides knowledge about the newly added function or device. 
     The guidance information presentation unit  111  may present guidance information for prompting the staff to attend a lecture of an educational service related to trouble, for example, when the same device as the plant device  100 A is used in another plant and trouble occurs in the device. 
     For example, the guidance information presentation unit  111  may present a number of basic education services for the first generation and present a basic educational service of more practical details accumulated in the past operation for the second generation and the third generation, in accordance with the generation of the staff. In addition, an educational service of details suitable for nurturing the grounded ability required for each generation such as introducing of case examples of a method of improving operation efficiency established during a daily operation may be presented. 
     Next, an example in which guidance information about human resource education for the entire organization instead of individual staff is presented will be described. 
       FIG. 9  is a flowchart showing an example of a process of outputting guidance information for prompting the staff to receive education in the embodiment of the present invention. 
     First, the operation data collection unit  101  collects operation data of the plant device  100 A and records the collected operation data in the storage unit  112  (step S 51 ). Next, the operation mode determination unit  104  determines a life stage of the plant device  100 A (step S 52 ). The specific determination method is as described in the flowcharts of  FIGS. 5 and 6 . The operation mode determination unit  104  outputs information about the determined life stage to the guidance information presentation unit  111 . 
     Next, the lecture attendance information acquisition unit  108  acquires and aggregates lecture attendance history information about all staff of all departments (step S 53 ). For example, in the storage unit  112 , information such as lecture attendance histories of educational services is recorded for all the staff in all the departments. The lecture attendance information acquisition unit  108  reads the lecture attendance information and aggregates the read information according to each department. Thereby, how many staff members are attending the lecture in what educational service in what department or the total number of staff members attending the lecture according to each department and according to each educational service is aggregated. The lecture attendance information acquisition unit  108  outputs the aggregated information to the guidance information presentation unit  111 . 
     Next, the trouble information acquisition unit  109  acquires aggregated information about trouble occurred in the plant  100  (step S 54 ). For example, in the storage unit  112 , various types of trouble occurring during a predetermined period or events leading to trouble are recorded, and the trouble information acquisition unit  109  reads the information and aggregates the information according to each trouble or event. The trouble information acquisition unit  109  outputs the aggregated information to the guidance information presentation unit  111 . 
     Next, the guidance information presentation unit  111  presents guidance information for prompting the staff to receive education in accordance with a lecture attendance history and the number of times of occurrence of trouble (step S 55 ). Specifically, the guidance information presentation unit  111  generates guidance information for prompting the staff to attend the lecture of an educational service for which a lecture attendance rate for a certain department is low when there is a low lecture attendance rate for the certain department in lecture attendance history information aggregated according to each department and each educational service acquired from the lecture attendance information acquisition unit  108  and outputs the generated guidance information to the management department terminal device  23 . For example, in the operation department, a lecture attendance rate of a “lecture for an operation monitoring department” is assumed to be 10%. The guidance information presentation unit  111  compares the lecture attendance rate with a lower limit (for example, 60%) of the lecture attendance rate of the educational service within a department, determines that the lecture attendance rate in the operation department is low, and outputs guidance information indicating that the “lecture attendance rate of the lecture for the operation monitoring department of the operation department is 10%. Please attend the lecture for the operation monitoring department” or the like to the management department terminal device  23 . The management department views the guidance information, determines that there is a possibility that a proficiency level of the operation department&#39;s skill is low, and prompts the staff to attend the lecture of the educational service for the operation department. 
     If the number of times of occurrence of certain trouble is greater than or equal to a predetermined threshold value in trouble-specific aggregated information acquired from the trouble information acquisition unit  109 , the guidance information presentation unit  111  generates guidance information for prompting the staff to attend a lecture of an educational service for providing knowledge required to prevent the trouble and outputs the generated guidance information to the management department terminal device  23 . The management department views the guidance information, determines that it is necessary to prevent trouble from reoccurring, and prompts the staff for each related department to attend a lecture of an educational service related to the trouble. 
     A process of outputting the guidance information for prompting the staff to receive the education may be executed periodically, for example, once a month, or may be executed at any timing according to an instruction of the staff of the management department. Thereby, it is possible to improve a level of knowledge of the entire organization, secure a certain level or more, steadily operate the plant, and strengthen a profit structure by entrusting the lecture attendance of the educational service to the department without entrusting the lecture attendance of the educational service to the individual. 
     Next, an example in which guidance information for outputting a consulting result related to the operation organization is presented will be described. 
       FIG. 10  is a flowchart showing an example of a process of outputting guidance information for a plant operation organization in the embodiment of the present invention. 
     First, the operation data collection unit  101  collects operation data of the plant device  100 A and records the collected operation data in the storage unit  112  (step S 61 ). Next, the operation mode determination unit  104  determines a life stage of the plant device  100 A (step S 62 ). A specific determination method is as described in the flowcharts of  FIGS. 5 and 6 . The operation mode determination unit  104  outputs information about the determined life stage to the guidance information presentation unit  111 . 
     Next, the operation organization information acquisition unit  106  acquires information about all staff for each department (step S 63 ). Next, the organization information comparison unit  110  compares a personnel composition of the operation organization of the plant  100  with a personnel composition of another plant (step S 64 ). For example, information about the personnel composition (the number of staff members for each department) for each life stage in another plant having the same type of plant device is recorded in the storage unit  112 . The organization information comparison unit  110  calculates the number of staff members for each department by totaling the number of staff members acquired by the operation organization information acquisition unit  106 . The operation organization information acquisition unit  106  compares the calculated number of staff members for each department with the number of staff members for each department in another plant for each life stage. The organization information comparison unit  110  outputs a comparison result to the guidance information presentation unit  111 . Next, the guidance information presentation unit  111  presents guidance information about the appropriate number of persons according to the life stage and the department (step S 65 ). For example, it is assumed that the number of staff members of the operation department of the other plant of the golden stage is 10 and the number of staff members of the operation department of the current plant (the plant  100 ) of the golden stage is 20. Then, the guidance information presentation unit  111  outputs guidance information indicating that the “number of staff members in the operation department is large” to the management department terminal device  23 . 
     Staff of the management department can use such guidance information as a trigger for reconsidering the personnel composition of the organization. By reconsidering the organization and redistributing human resources, it is possible to optimize the operation organization. 
       FIG. 11  is a schematic block diagram showing a configuration of a computer according to at least one embodiment.
