Description

[Technical field]

[0001] The present invention relates to an organization design support device, an organization design support method, and an organization design support program. [Background technology]

[0002] In recent years, the business environment has changed rapidly, and various industries are required to review and improve their business design (business plans) in response to the business environment. For example, in the maintenance of infrastructure, railways, industrial equipment, medical equipment, etc., it is necessary to continuously carry out maintenance such as inspection, repair, and replacement to ensure the safe and stable operation of assets (power equipment, etc.). In particular, in the power industry, there is a strong demand for a safe and stable supply of electricity with high operation rates, as the diversification of assets progresses, such as the construction and renewal of facilities due to an increase in aging and obsolete facilities, and the increase in renewable energy. In order to respond to the diversification of assets and achieve stable facility operation with high availability, it is important to perform maintenance work by appropriately prioritizing according to the operating status and operating characteristics of assets and prevent breakdowns from occurring.

[0003] A method for supporting the execution of such maintenance work is described in Patent Document 1. Patent Document 1 discloses the following with respect to the maintenance of water treatment devices. an equipment evaluation database storing, as equipment evaluation data, priority of a plurality of stations equipped with water treatment equipment for carrying out maintenance work; an equipment evaluation database storing, as equipment evaluation data, data on the importance and healthiness of water treatment equipment installed at each station; an equipment evaluation database storing, as equipment evaluation data, data on the importance and healthiness of equipment installed in each water treatment equipment; an equipment priority calculation unit calculating, based on the station evaluation data stored in the station evaluation database and the equipment evaluation data stored in the equipment evaluation database, a water treatment equipment selection unit selecting water treatment equipment for which maintenance work is to be performed in accordance with the priority calculated by the equipment priority calculation unit; a equipment selection unit reading, from the equipment evaluation database, equipment evaluation data of equipment installed in the water treatment equipment selected by the equipment selection unit, and selecting equipment for which maintenance work is to be performed based on the equipment evaluation data read out; and a determination unit determining and outputting a priority order for carrying out maintenance work for the equipment selected by the equipment selection unit.

[0004] [Patent Document 1] JP 2012-208930 A Summary of the Invention [Problem to be solved by the invention]

[0005] When designing (planning) maintenance work and other tasks, it is also important to consider organizational design, i.e., how to structure the organizations in each area to which the maintenance workers who will carry out the work belong. Maintenance workers from the organization in charge of an area are assigned to the maintenance task of inspecting assets that belong to that area. Therefore, we are considering using computers to assist in organizational design, which designs organizations in advance in proportion to the workload of maintenance work in each area. In other words, organizational design means deciding in advance how many personnel should be prepared in each base (area).

[0006] First, as the business environment, including society, the environment, customers, and technology, changes rapidly, the key to the sustainable development of a company is to accurately grasp the daily changes in the situation and continue to flexibly transform its business. In particular, in the power sector, the diversification of assets is progressing, with an increase in aging facilities and the expansion of the introduction of renewable energy facilities. In addition, with the development of sensors, communication technologies, and data analysis technologies, the introduction of new IoT technologies such as predictive diagnosis is also progressing. With these changes in assets and technologies, the methods of maintenance tasks must also be transformed, and maintenance tasks are becoming more diverse.

[0007] On the other hand, there is a growing shortage of maintenance personnel to carry out maintenance tasks, and it has become necessary to carry out a variety of maintenance tasks with limited personnel. If a shortage of personnel makes it impossible to carry out necessary maintenance tasks, unexpected breakdowns will occur, causing equipment to be shut down for long periods of time, and equipment operating companies will incur large loss costs. In addition, since the tasks that maintenance personnel can handle vary depending on their skills and scope of responsibility, if an organization that can supply maintenance personnel capable of handling the maintenance tasks that arise is not established in advance, problems such as maintenance work not being able to be carried out at the appropriate time and work being concentrated on certain maintenance personnel will occur.

[0008] However, Patent Document 1 only describes that the number of personnel by job type available for repair or restoration is extracted from a maintenance company database, and is silent on the specific organizational design, such as from which area and from which organization the "available maintenance personnel" will be procured. If there are too few maintenance staff and maintenance tasks, the number of breakdowns will increase, downtime will increase, and the availability rate will decrease. On the other hand, if there are too many maintenance staff and maintenance tasks, the downtime for maintenance will be longer and the availability rate will decrease.

[0009] Therefore, a main object of the present invention is to support the design of a well-balanced and appropriate organizational structure that matches the workload of each piece of equipment. [Means for solving the problem]

[0010] In order to solve the above problems, the tissue design assistance device of the present invention has the following features. The present invention relates to an input unit that receives, as various input information, equipment information indicating equipment that is a target of work, task information indicating the work content to be performed on the equipment, and organization information indicating the organization to which the person who will perform the work content belongs; a workload calculation unit that calculates a workload for each task based on the various input information received by the input unit; a counting unit that counts the amount of work calculated by the work amount calculation unit for each organization in the organizational information; The system further comprises a display unit that displays the amount of work, which is the result of the calculation by the calculation unit. Other means will be described later. Effect of the Invention

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, a first embodiment and a second embodiment of the present invention will be described with reference to the drawings. EXAMPLES

[0014] Example 1 will now be described. FIG. 1 is a configuration diagram of a organization design assistance device 100 according to the first embodiment. The organization design support device 100 has an input unit 14, a workload calculation unit 15, a classification unit 16 (a task type classification unit 16a described in FIG. 10 and a maintenance organization classification unit 16b described in FIG. 11), an evaluation unit 17, and a display unit 18. The input unit 14 receives, as various input information, facility information 11 indicating the facility to be worked on, maintenance task information 12 indicating the work to be done on the facility, and maintenance organization information 13 indicating the organization to which the person who will perform the work belongs. In the following, an example will be described in which the input unit 14 receives various input information related to the design of a maintenance work. Note that the maintenance work may include indirect work such as meetings, records, sales, and clerical work in addition to work directly related to facility maintenance such as inspection, repair, maintenance, replacement, installation, and disposal. Also, the assets that are the subject of the maintenance work include various items such as facilities, equipment, machines, and products.

[0015] The workload calculation unit 15 calculates the workload for each task based on various input information received by the input unit 14. The classification unit 16 classifies the workload calculated by the workload calculation unit 15 for each organization in the maintenance organization information 13 (further, for each organization and for each task type of the task). The evaluation unit 17 counts the classification results of the classification unit 16 for each organization in the maintenance organization information 13 (further, for each organization and for each task type of the work content). The display unit 18 displays the workload, which is the counted result.

[0016] Figure 2 is a table showing the main categories of input information for maintenance work and the main design contents for each category. The input information for maintenance work includes the following: The maintenance task information 12 includes a maintenance task list to be executed for each piece of equipment, and a maintenance task design for designing the execution frequency and execution trigger for each task. Maintenance organization information 13 includes maintenance organization design, which designs the allocation of maintenance personnel, team composition, scope of responsibility, skill plan, outsourcing plan, etc. Equipment information 11 includes spare parts design, which designs the number of spare parts to be held for each part of the target equipment and the layout of the storage warehouse.

[0017] FIG. 3 is a diagram showing the hardware configuration of the organization design assistance device 100. As shown in FIG. The organization design assistance device 100 is configured as a computer 900 having a CPU 901 , a RAM 902 , a ROM 903 , a HDD 904 , a communication I / F 905 , an input / output I / F 906 , and a media I / F 907 . The communication I / F 905 is connected to an external communication device 915. The input / output I / F 906 is connected to an input / output device 916. The media I / F 907 reads and writes data from a recording medium 917. Furthermore, the CPU 901 executes a program (also called an application or its abbreviation, an app) loaded into the RAM 902, thereby improving and controlling each processing unit. This program can also be distributed via a communication line, or recorded on a recording medium 917 such as a CD-ROM and distributed.

[0018] 4 is a table showing an example of the facility information 11. In the facility information 11, the following information is associated with each asset (electric power facility) ID. -ID indicating the location where the asset is installed (site ID and installation area ID). The ID of the asset that is connected to the asset (connected asset). The ID of the asset that functions in cooperation with the asset (functional cooperation asset). Note that a connected asset is an asset that is directly connected physically, and a functional cooperation asset is an asset that functions in cooperation with a set of multiple assets (for example, a simultaneous power outage). The asset type. - The number of years that have passed since the asset began to be used. Health index, which is an index of the equipment health of the asset. In Figure 4, a health index of "0" is the healthiest (no breakdowns or deterioration), and a health index of "100" is the least healthy (broken down). The importance of the asset. For example, the more important an asset is, the more important it is because it supplies power to or controls a large number of assets.

[0019] Moreover, the facility information 11 is embodied in the table of FIG. The power network configuration of facility information 11 is embodied in the site ID, asset ID, connection asset, and functional collaboration asset in Figure 4. The equipment configuration of facility information 11 is specified by the asset ID and model in Figure 4. Although not shown in this example, information on the components of each model is also included in the equipment configuration. The operation information of the equipment information 11 is embodied in the number of years elapsed and the Health index in Figure 4. The reliability information of equipment information 11 is embodied in the model, health index, and importance in Figure 4. In general, the failure rate and other information are calculated from this information. The inspection power outage area (power outage area during maintenance) in the equipment information 11 is specified by the area ID in Fig. 4. The power outage here is not an accidental power outage caused by a disaster, but an artificial planned power outage to allow maintenance personnel to perform maintenance work such as inspection. The input unit 14 receives the equipment information 11, which includes information on which equipment belongs to which area as information on areas where power will be cut off all at once during inspection work on the equipment that is the target of the work.

[0020] FIG. 5 is a diagram showing the equipment configuration of a substation, illustrating the facility information 11 of FIG. In Fig. 5, individual assets are illustrated for each asset ID (PS1, etc.) in Fig. 4, and the connection lines between each asset by power supply lines reflect the connection relationships by the connection assets in Fig. 4. In the substation, power is supplied from two sources (PS1, PS2) and sent to three loads (L1 to L3) through several transforming equipment such as circuit breakers (CB1 to CB4), transformers (PT1, PT2), switches (SW1, SW2), and bus bars (BB1, BB2).

[0021] In addition, in the case of a substation, when a specific asset stops due to a breakdown or maintenance, maintenance personnel perform a unique operation called "switching" to open nearby circuit breakers or switches in coordination to isolate the asset under maintenance. Information on assets that are to be functionally linked when each asset stops is specified in the functionally linked assets item in Figure 4. For example, if asset PT1 stops, maintenance personnel will operate CB1, CB3, and CB4 in coordination to the open state. By performing such "switching" operations, substations are operated to minimize the scope of impact of stopped assets and reduce the power supply to the load as much as possible.

[0022] In the example of Figure 5, the area is divided into areas A through C, reflecting the area IDs in Figure 4. Maintenance personnel stop assets for a set period of time in each area to perform maintenance work. When an asset in an area is stopped for maintenance, maintenance personnel may also take the opportunity to inspect other assets in the same area. The importance items in Figure 4 are defined, for example, by the extent of the impact when an asset is stopped.

[0023] 6 is a table showing an example of the maintenance task information 12. In the maintenance task information 12, the following information is associated with each model of the asset to be maintained (target model). Here, transformers (Task-1 to Task-4) and circuit breakers (Task-5 to Task-8) are shown as examples. Maintenance task details (task ID, task type) -Information on resources required to perform maintenance tasks (skills required, number of maintenance personnel required, standard work hours) -Information on when performing maintenance tasks (whether there was a power outage during work, work execution trigger, work cost)

[0024] 7 is a table showing an example of the maintenance organization information 13. The maintenance organization information 13 holds the following information for each individual maintenance worker identified by a maintenance worker ID. ·Skills possessed by maintenance staff - Information about the organization to which the maintenance worker belongs (the ID of the location where the maintenance worker is present) - Specific work information for maintenance personnel (area of ​​responsibility, start time, end time, scheduled holidays, labor costs)

[0025] 8 is a table showing an example of the task allocation information 15b. The task allocation information 15b shows the correspondence between the maintenance tasks on the vertical axis and the maintenance workers on the horizontal axis. For example, a circle is marked in the cell where Task-1 and Worker-1 intersect, which indicates that Worker-1 can handle Task-1. Note that if there are few maintenance personnel who can handle a certain task, there is a higher risk that the task cannot be performed in a timely manner due to a lack of personnel. The input unit 14 (manual input) or the workload calculation unit 15 (automatic calculation) refers to the maintenance task information 12 shown in FIG. 6 and the maintenance organization information 13 shown in FIG. 7, and creates task assignment information 15b including availability information shown by circles in FIG. 8, taking into consideration multiple elements such as the skills of maintenance personnel, the base station where they are present, and the scope of their responsibilities.

[0026] The task allocation information 15b may be input by the user each time, but may also be input in conjunction with information held by another system, as exemplified below. - Enterprise Asset Management (EAM) ·Asset Performance Management (APM) ·Condition Monitoring System (CMS) If the organization design support device 100 is linked to another system, it can reduce the effort of inputting information by the user and can operate assets while updating the latest information on facilities each time. Furthermore, the task allocation information 15b may be stored as a database inside the organization design support device 100.

[0027] 9 is a Gantt chart showing the calculation results of the workload calculation unit 15. In this Gantt chart, the vertical direction is divided by maintenance worker ID (maintenance worker), and the horizontal direction shows a work schedule in which time passes as one moves to the right. Each element in the Gantt chart is described as a task type: A: inspection, B: periodic maintenance, C: preventive maintenance, and D: corrective maintenance. For example, the work schedule of maintenance worker Worker-1 is set up so that short-term A: inspection → break → B: regular maintenance → break → medium-term A: inspection, in that order. On the other hand, the work schedule of maintenance worker Worker-2 is set up so that short-term A: inspection → break → long-term B: regular maintenance → break → short-term C: preventive maintenance, in that order.

[0028] The workload calculation unit 15 calculates the amount of maintenance workload to be generated based on the task allocation information 15b and various information received by the input unit . The calculation of the workload can be realized, for example, by a maintenance work simulation using an agent simulation, in which each character in the real world is represented by a model called an agent. For example, in the case of agent simulation of maintenance work, asset data corresponding to each individual asset in the simulation world is generated for each management unit such as real-world assets or asset parts, and the behavior of real-world assets is reproduced by having these assets autonomously operate and break down. The data generated at this time is called an agent, and in the case of assets, it is called an asset agent.

[0029] Asset agents can be created using facility information 11. Similarly, maintenance workers are also generated as agents in the simulation world, one by one, and are called maintenance agent. Maintenance agents can be created using maintenance organization information 13. Maintenance agents perform maintenance tasks defined in maintenance task information 12. In addition to maintenance tasks, the behavior of maintenance workers in actual maintenance work, such as waiting, moving, and resting, is also reproduced. As a result, when a task such as periodic maintenance or responding to a failure occurs for an asset agent, the workload calculation unit 15 extracts a maintenance agent who can handle the task based on task allocation information 15b and assigns the task to the asset agent. In this way, by simulating on a computer the behavior of asset operation, the occurrence of failures, and the behavior of maintenance personnel performing maintenance tasks, and recording the time when each event occurred, it is possible to calculate the amount of maintenance work (work time) for each maintenance personnel, as shown in Figure 9.

[0030] The classification unit 16 classifies the workload calculated by the workload calculation unit 15 according to any one of the items included in the facility information 11, the maintenance task information 12, and the maintenance organization information 13. In the example of Fig. 9, the maintenance organization classification unit 16b of the classification unit 16 classifies the amount of work (work time) for each of the three organizations defined in the maintenance organization information 13. In the following, in this specification, an example in which an organization is formed for each area will be described. In other words, one organization is designed for one area. · Work load for area A: 201 · Work load for area B: 202 Work load for area C: 203

[0031] Furthermore, the task type classification unit 16 a of the classification unit 16 may classify the workload 201 for the area A according to the task types defined in the maintenance task information 12 . Of the work volume 201 for area A, A is the volume of work per inspection. Of the work volume 201 for area A, B is the volume of work for regular maintenance. Of the work volume 201 for area A, C is the volume of work for preventive maintenance. Of the work volume 201 for area A, D is the volume of work for corrective maintenance. Similarly to the above, the workload 202 for area B and the workload 203 for area C can also be subdivided by task type.

[0032] The evaluation unit 17 evaluates the workload by tallying up the workload for each classification result of the classification unit 16. The evaluation result by the evaluation unit 17 is displayed on the display unit 18 and presented to the user via a display or the like. Furthermore, the evaluation unit 17 may perform the following evaluation in order to display the tally up results of the workload in an easily understandable manner. (Evaluation 1) Simply compare the amount of work per category (Figure 10). (Evaluation 2) Setting a target value for the amount of work in advance and calculating and detecting deviations from the target value (Figure 11). (Evaluation 3) Rank according to the amount of work (Figure 13 shows the rankings in three areas: low / medium / high risk).

[0033] As described above, the workload calculation unit 15 calculates as simulation results who performed what type of task, when, for which asset, and how long the task took. These simulation results are tagged with facility information (which asset), maintenance task information (what type of task), and maintenance organization information (who) for each task time (workload). The classification unit 16 classifies each operation time according to items (eg, area, task type, base, etc.) included in the various information. The evaluation unit 17 tallies (total, average, etc.) each task time for each classification result of the classification unit 16, and outputs the tallied results on the screen of the display unit 18 as comparable evaluation values ​​for each classification.

[0034] Hereinafter, examples of displaying the evaluation results by the evaluation unit 17 in the first embodiment will be described with reference to Figs. Fig. 10 is a screen display diagram showing the results of the task type classification unit 16a classifying the work time by task type, dividing it by area, and comparing it with a bar graph. In this screen display diagram, the work time corresponds to downtime (power outage time during inspection). By performing such an evaluation, the manager can compare the work volume balance by area, and optimize the task design. For example, a manager can consider whether it is possible to reduce downtime by switching from corrective maintenance to preventive maintenance, since the proportion of corrective maintenance is higher in Area B than in other areas. Managers can also compare the work balance between areas and optimize task and resource allocation. For example, a manager can consider whether it is possible to shorten the work hours in Area C by transferring some of the personnel in charge of Area B to Area C, since the amount of work in Area C is greater than that in Area B.

[0035] FIG. 11 is a screen display diagram showing the results of the maintenance organization classification unit 16b comparing the work hours of each maintenance worker and each base in a bar graph. When display unit 18 displays the workload that is the result of the compilation by classification unit 16, it also displays a preset target value for the workload. By performing such an evaluation, the manager can compare the workload balance of each maintenance worker and optimize the allocation of maintenance workers and their scope of responsibility. For example, at base C, Worker-9 has a small workload, while the other workers have relatively large workloads, so the manager can consider whether they can review the scope of responsibility to equalize the workload.

[0036] 12 is a screen display diagram showing the result of the task type classification unit 16a displaying the workload for each task type in a time series graph going into the future. In this screen display diagram, an assumed scenario of switching the task method from periodic maintenance to preventive maintenance is input. By conducting such an evaluation, the manager can predict future risks and consider design changes to maintenance work in advance. For example, the manager predicts that the amount of corrective maintenance required to respond to breakdowns will increase dramatically in the next few years due to the progression of equipment aging. Therefore, the manager can consider future task design, such as whether it is possible to prevent breakdowns before they occur by introducing more preventive maintenance than currently expected.

[0037] Fig. 13 is a screen display diagram of the results plotted by the maintenance organization classification unit 16b for each base, with the vertical axis representing the amount of work generated and the horizontal axis representing available work capacity. In this way, the display unit 18 displays the results plotted by the maintenance organization classification unit 16b on a matrix with two axes. This allows the manager to visually grasp the status of each base and consider organizational design. Work capacity is an index showing how quickly a response can be made when an emergency response is required due to an unexpected breakdown, etc., and here we use the standby time of maintenance personnel at their base. If a certain amount of standby time is secured at the base, a quick response can be made to an unexpected event. On the other hand, if the standby time is too long, it can be said that the maintenance personnel have too much free time, and that their resources are not being used effectively.

[0038] The display unit 18 plots and displays the workload, which is the result of the aggregation by the aggregation unit (classification unit 16 and evaluation unit 17), on a matrix having multiple axes. For example, the display unit 18 plots the workload, which is the result of the aggregation by the classification unit 16, on a matrix having an axis representing an indicator of the work capacity that an organization in the maintenance organization information 13 can provide and an indicator of the workload generated by the work content in the maintenance task information 12, and displays the screen display diagram of FIG. This screen display evaluates the risk of organizational design in a matrix (a combination of vertical and horizontal axes), with the lower left area being low risk, the center area being medium risk, and the upper right area being high risk. In other words, within the matrix, risk levels are preset in three stages according to the amount of work generated and the amount of spare capacity. Risk levels are expressed by the darkness of the color, with darker areas indicating high-risk zones with a large amount of work generated and little spare capacity. Furthermore, when the display unit 18 displays the workload that is the result of the compilation by the classification unit 16, it displays the workload as information ranked according to the magnitude of the workload.

[0039] It is important to design the organization so that standby times are kept within an appropriate range, in accordance with Figure 13. By referring to the screen display in Figure 13, managers can compare the balance between the workload and spare capacity of each base, and optimize personnel deployment. For example, because base C is in a high-risk state, the manager can consider transferring personnel from base B, which has spare capacity, to base C. Furthermore, the evaluation unit 17 may determine whether or not to encourage personnel movement between bases based on the workload and available capacity of each base. For example, the evaluation unit 17 may calculate a ratio obtained by dividing the workload of each base by the available capacity, and when the calculated ratio of a certain base C exceeds a predetermined threshold (i.e., when the workload of base C is large compared to the available capacity), determine to encourage personnel movement from another base B to base C. Furthermore, the evaluation unit 17 may support the manager by displaying information encouraging personnel movement from base B to base C as an arrow display 301 on the screen. That is, when the display unit 18 displays the workload that is the result of the aggregation by the classification unit 16, it also displays the proposal information (arrow display 301) for smoothing the workload for each organization.

[0040] The organization design support device 100 of the first embodiment described above provides a maintenance design method that can respond to diversification of assets and realize efficient operation and maintenance that maintains a high operating rate. In particular, it appropriately designs maintenance tasks and a maintenance organization in a well-balanced manner according to the equipment status, which is an important point in maintenance design. This allows managers to quantitatively grasp the balance and impact of workload for each maintenance task and each maintenance organization, enabling them to flexibly and appropriately design maintenance tasks and organizations according to the equipment status. As a result, managers can flexibly change the organizational structure in line with asset transitions and advances in IoT (Internet of Things) technology. Such organizational changes (optimization) can avoid business risks such as long-term equipment shutdowns, improve resilience, and improve the work-life balance of maintenance personnel.

[0041] Moreover, according to the organization design assistance device 100 of the first embodiment, the following unbalanced organization designs can be brought to the attention of the manager through the screen displays of FIGS. 10 to 13. - The amount of maintenance work for the equipment in the area that a certain base is responsible for is excessive for the number of personnel employed at that base, and maintenance personnel are constantly overwhelmed with tasks and overtime is the norm. In addition, when a sudden event such as a breakdown occurs, there are no personnel who can respond quickly, which leads to long-term operation shutdowns. - The amount of maintenance work required for the equipment in the area that a certain base is responsible for is too small for the number of personnel employed at that base, and maintenance personnel are left idle waiting for tasks at the base. In this case, the maintenance company is paying unnecessary labor costs and is inefficient.

[0042] As a result, the screen display of the organization design assistance device 100 enables the manager to adopt an organization design that has been improved as follows. An organizational design in which the amount of maintenance work required for the equipment in the area that a particular site is responsible for is just right for the personnel employed at that site, and the work is carried out with a moderate workload. An organizational design that minimizes overtime, minimizes time spent waiting for tasks at the base, and leaves enough slack to be able to respond quickly to unexpected events such as breakdowns. EXAMPLES

[0043] Hereinafter, a description will be given of Example 2. In Example 1, a single organizational design pattern has been described, but in Example 2, the organizational design assistance device 100 is expanded so as to handle a plurality of organizational design patterns (hypotheses).

[0044] Fig. 14 is a configuration diagram of a tissue design assistance device 100 of the embodiment 2. Note that the same reference numerals in Fig. 14 and Fig. 1 indicate the same parts, so repeated explanations will be omitted and only the differences will be explained. 1, the organization design support device 100 in Fig. 14 is provided with a plurality of patterns of various input information (maintenance task information 12 and maintenance organization information 13) to be received by the input unit 14. The classification unit 16 is expanded so as to handle a plurality of patterns.

[0045] The task design pattern classification unit 16c (FIG. 14), which handles multiple patterns, is an extension of the task type classification unit 16a (FIG. 1), which handles one pattern (design pattern by task type of the maintenance task information 12). The task design pattern classification unit 16c classifies the workload calculated by the workload calculation unit 15 by pattern (by three execution triggers) based on, for example, three patterns of maintenance task information 12a, 12b, and 12c, which have different execution triggers (occasions) for the maintenance tasks. As the execution trigger, indices such as the elapsed time since the previous task execution, health index, and importance can be used. When the elapsed time since the previous task execution is specified as the execution trigger, so-called time-based maintenance (TBM) is achieved. When an index such as health index or importance is specified as the execution trigger, so-called condition-based maintenance (CBM) is achieved.

[0046] In this way, designing tasks by changing the type of execution trigger for each task is equivalent to changing the strategy (maintenance policy) for executing maintenance tasks such as TBM and CBM. Therefore, the input unit 14 accepts a plurality of maintenance task information 12 with different work execution triggers as various patterns of input information. The workload calculation unit 15 calculates the workload for each work content for each pattern. The classification unit 16 and the evaluation unit 17 tally up the workload calculated by the workload calculation unit 15 for each pattern.

[0047] Moreover, the organization design pattern classification unit 16d (FIG. 14), which handles multiple patterns, is an extension of the maintenance organization classification unit 16b (FIG. 1), which handles one pattern (the organization-specific design pattern of the maintenance organization information 13). The organization design pattern classification unit 16d classifies the workload calculated by the workload calculation unit 15 by pattern (by three maintenance worker allocations) based on, for example, three patterns of maintenance organization information 13a, 13b, and 13c, which have different organizational structures (maintenance worker allocations). Maintenance worker allocation corresponds to, for example, determining the base or team to which each maintenance worker belongs. Therefore, the input unit 14 accepts a plurality of maintenance organization information 13 with different organizational structures as various patterns of input information. The workload calculation unit 15 calculates the workload for each work content for each pattern. The classification unit 16 and the evaluation unit 17 tally up the workload calculated by the workload calculation unit 15 for each pattern.

[0048] Hereinafter, a display example of the evaluation result by the evaluation unit 17 in the second embodiment will be described with reference to FIGS. 15 is a screen display diagram showing the results of a comparison, by the task design pattern classification unit 16c, of the work time for each area for each task design pattern with different execution triggers, using a bar graph. Work time is proportional to work cost. By performing such an evaluation, the administrator can find the task design pattern that minimizes the work cost from among multiple task design patterns, and improve and optimize the maintenance policy. For example, in Figure 15, the administrator can determine that task design pattern "3" is promising because the work time for each area is relatively uniform and the work cost is small.

[0049] FIG. 16 is a screen display diagram showing the results of the organization design pattern classification unit 16d comparing the waiting time (available capacity) for each area for each organization design pattern with different organization structures, using a bar graph. By performing such an evaluation, the manager can select from among multiple organizational design patterns the one with the most responsiveness and adequate spare capacity, thereby improving and optimizing the maintenance organizational design. For example, in Figure 16, the manager can determine that organizational design pattern "2" is promising, as it has an adequate spare capacity and a good balance of spare capacity for each area.

[0050] According to the organization design assistance device 100 of the second embodiment described above, the manager can quantitatively compare a plurality of maintenance task design patterns, and can improve and optimize the maintenance task design (maintenance policy). Also, according to the organization design assistance device 100 of the second embodiment, the manager can quantitatively compare a plurality of maintenance organization design patterns, and can improve and optimize the maintenance organization design.

[0051] Furthermore, the present invention is not limited to the above-described embodiments, and various other application examples and modifications are possible without departing from the gist of the present invention described in the claims. For example, the above-described embodiments are detailed and specific descriptions of the configuration of the organization design support device 100 in order to easily explain the present invention, and are not necessarily limited to those including all of the components described.

It is also possible to add a component of another embodiment to the configuration of one embodiment. It is also possible to add, replace, or delete other components to, a part of the configuration of each embodiment.

[0052] In addition, the above-mentioned configurations, functions, processing units, etc. may be realized in part or in whole by hardware, for example, by designing them as integrated circuits. As the hardware, a broad processor device such as an FPGA (Field Programmable Gate Array) or an ASIC (Application Specific Integrated Circuit) may be used.
