Description

[Technical field]

[0001] One aspect of the present invention relates to an output device. [Background technology]

[0002] Patent Document 1 discloses a system that formulates plans for managing and updating facilities that are made up of a combination of assets that are made up of multiple parts. In this system, if there is a year in which maintenance costs exceed the budget, the implementation year of the business plan is postponed based on risk costs. Risk costs are costs incurred to deal with breakdowns that may occur when the soundness of the facility deteriorates. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 4642085 Summary of the Invention [Problem to be solved by the invention]

[0004] When maintenance costs are adjusted using the system of Patent Document 1, there is a risk that the adjusted maintenance costs will vary greatly from year to year. If there is a large variation in maintenance costs, there is a risk that the financial burden on users will vary significantly from year to year, and there is a risk that the financial burden will increase depending on the business performance of each year.

[0005] An aspect of the present disclosure aims to realize an output device that makes it possible to optimize the renewal project costs required for updating a plurality of devices for each predetermined period of time. [Means for solving the problem]

[0006] The output device of aspect 1 of the present invention comprises an acquisition unit that acquires an upper limit value of renewal project costs required to update at least any of a plurality of devices arranged in a facility for each of a plurality of specified periods, the upper limit value of the renewal project costs being set by an input operation, a leveling processing unit that leveles out the renewal project costs over the plurality of specified periods so that they are below the upper limit value based on the installation time of the device, the update period for updating the device, and the update cost required to update the device, which are set in advance for each of the plurality of devices, and a first output unit that outputs the leveled renewal project costs over the plurality of specified periods.

[0007] According to the above configuration, the output device outputs the renewal project cost leveled based on the upper limit value set by the input operation. This makes it possible to present the leveled renewal project cost to the user, so that the user can recognize whether the renewal project cost has been leveled as desired. If the renewal project cost has not been leveled as desired, the user can reset the upper limit value by inputting the output device, which obtains the reset upper limit value and outputs the renewal project cost leveled again based on the upper limit value.

[0008] Therefore, the output device can optimize the renewal project costs over a plurality of predetermined periods as desired by the user by acquiring the upper limit value through input operations and outputting the renewal project costs leveled based on the upper limit value. Therefore, the financial burden of the renewal project costs for each predetermined period can be leveled.

[0009] An output device according to a second aspect of the present invention is the output device of the first aspect, in which a priority order is set for each of the plurality of pieces of equipment for selecting the equipment when leveling the renewal project costs, and the leveling processing unit includes an addition unit that adds the renewal costs in a first period of the plurality of specified periods based on the installation date and the renewal cycle in order of the priority order, and a judgment unit that judges whether the renewal project costs in the first period have exceeded the upper limit value, and if the renewal project costs exceed the upper limit value, the addition unit adds the renewal costs added in the first period in a second period different from the first period instead of the first period.

[0010] According to the above configuration, the output device can level out the renewal project costs over a plurality of predetermined periods so as not to exceed the upper limit value.

[0011] The output device according to a third aspect of the present invention is the output device of the second aspect, further comprising: a first calculation unit that calculates an evaluation score for each of the plurality of devices, which is an evaluation index for the safety of the devices; and a setting unit that sets the priority order in ascending order of the evaluation score for the devices.

[0012] According to the above configuration, it can be estimated that the lower the evaluation score, the more deteriorated the equipment is. Therefore, the output device can prioritize the renewal time so that the renewal cost is added according to the preset renewal cycle for the more deteriorated equipment, and can then level out the renewal project cost.

[0013] An output device according to a fourth aspect of the present invention is the output device of the third aspect, wherein the setting unit sets the priority order of two or more pieces of equipment having the same evaluation score in any one of the following orders: the order of largest value obtained by subtracting the update cycle from the number of years elapsed since the installation date, the order of oldest installation date, and the order of lowest update cost.

[0014] According to the above configuration, even if there are two or more devices with the same evaluation points, different priorities can be set for the devices.

[0015] An output device according to aspect 5 of the present invention is the output device of any of aspects 1 to 4, wherein a plurality of types of update periods are pre-set as the update period for each of the plurality of devices, and the output device is provided with: a second calculation unit that calculates the update project cost corresponding to each of the plurality of types of update periods over the plurality of specified periods based on the installation time, the plurality of types of update periods, and the update cost; and a second output unit that outputs the update project cost over the plurality of specified periods calculated by the second calculation unit for each of the plurality of types of update periods.

[0016] According to the above configuration, the output device outputs the renewal project costs over a plurality of predetermined periods for each of a plurality of types of renewal cycles, so that the user can determine the upper limit of the renewal project costs to be used for leveling after comparing and examining the trends of the plurality of renewal project costs. Therefore, the user can easily determine the upper limit that is estimated to be preferable for leveling at an early stage.

[0017] An output device according to a sixth aspect of the present invention is the output device of the fifth aspect, wherein the second calculation unit calculates the renewal project cost corresponding to at least one of the plurality of renewal periods based on at least one of the renewal period and the renewal cost changed by an input operation.

[0018] According to the above configuration, the output device outputs the renewal project cost based on the renewed renewal period and / or renewal cost each time the renewal period and / or renewal cost are changed. Therefore, the output device can calculate and output various renewal project costs for each of a plurality of types of renewal periods. Therefore, the user can determine the upper limit of the renewal project cost through various simulations.

[0019] The control method for an output device according to aspect 7 of the present invention includes an acquisition step of acquiring an upper limit value of renewal project costs required for updating at least any of a plurality of devices arranged in a facility for each of a plurality of specified periods, the upper limit value of the renewal project costs being set by an input operation; a leveling processing step of leveling out the renewal project costs over the plurality of specified periods so that they are below the upper limit value based on the installation time of the device, the renewal period for updating the device, and the renewal cost required for updating the device, all of which are set in advance for each of the plurality of devices; and a first output step of outputting the leveled renewal project costs over the plurality of specified periods.

[0020] According to the control method of the output device, the renewal project cost leveled based on the upper limit value set by the input operation is output. This makes it possible to present the leveled renewal project cost to the user, so that the user can recognize whether the renewal project cost has been leveled as desired. If the renewal project cost has not been leveled as desired, the user can reset the upper limit value by inputting an input operation, thereby acquiring the reset upper limit value in the control method, and outputting the renewal project cost leveled again based on the upper limit value.

[0021] Therefore, in the above control method, the upper limit is obtained by inputting the data, and the renewal project cost is output based on the upper limit, so that the renewal project cost over a plurality of predetermined periods can be optimized as desired by the user. Therefore, the financial burden of the renewal project cost for each predetermined period can be leveled.

[0022] The deterioration prediction device according to each aspect of the present invention may be realized by a computer. In this case, the deterioration prediction device program that causes a computer to operate as each part (software element) of the deterioration prediction device to realize the deterioration prediction device on a computer, and a computer-readable recording medium on which the program is recorded, also fall within the scope of the present invention. Effect of the Invention

[0023] According to an embodiment of the output device and a control method thereof, it is possible to optimize the renewal project costs required for the renewal of a plurality of devices for each predetermined period of time. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0025] [Output System] 1 is a functional block diagram showing a schematic configuration of an output system 1. The output system 1 is a system that calculates project costs for each predetermined period and outputs the results. In this embodiment, the output system 1 is a system that calculates renewal project costs for each predetermined period and outputs the results.

[0026] The project cost is the project cost required to update (replace), repair, and / or inspect at least one of the multiple devices arranged in the facility during each of multiple specified periods. Therefore, the renewal project cost is the project cost required to update at least one of the multiple devices arranged in the facility during each of multiple specified periods.

[0027] The specified period is a period during which the costs for updating, repairing, and / or inspecting the equipment are allocated, and may be, for example, a fiscal year. In the following explanation, the specified period may also be referred to as a "fiscal year." The multiple specified periods are periods during which the trends in the renewal project costs are shown, and are periods during which the user considers the renewal project costs for each fiscal year. In the following explanation, the multiple specified periods are referred to as "renewal consideration periods."

[0028] The facility may be, for example, a water facility. The water facility may include, for example, a water intake facility, a water purification facility, and a water supply and distribution facility. The equipment may include, for example, a water supply pump, a power generation facility, an electric valve, a water intake flow meter, and a hypochlorous injection device. Other equipment may include, for example, a pump room, a sedimentation tank, a water supply reservoir, a management building, a pressure reducing valve room, a building, and other structures.

[0029] As shown in FIG. 1, the output system 1 includes, for example, a management device 2, an output device 3, an operation device 4, and a display device 5.

[0030] The management device 2 is a device that manages an equipment list D21 that shows a list of equipment arranged in a facility. The equipment list D21 includes data such as the name of the equipment, the type of equipment, the manufacturing date, the installation date (installation time), and the name of the facility. In addition, the equipment list D21 includes data such as the update cycle for updating the equipment, the repair cycle for repairing the equipment, the inspection cycle for inspecting the equipment, the update cost required for updating the equipment, the repair cost required for repairing the equipment, and the inspection cost required for inspecting the equipment.

[0031] The type of equipment may include, for example, first type data indicating the function of the equipment and the type of structure. The functions of the equipment may include, for example, pumps, valves, flow meters, and chemical injection machines. The type of structure may include, for example, the type of business that constructed the structure (whether it is a building built by a civil engineering project or other buildings, etc.). The type of equipment may include, for example, second type data indicating the use of the facility in which the equipment is installed, such as a facility building or an office building. In Figures 3 and 4, etc., the first type data is indicated as "equipment family" and the second type data is indicated as "equipment type".

[0032] The output device 3 is a device that calculates the project cost for each predetermined period and outputs the result. In this embodiment, the output device 3 is a device that calculates the renewal project cost for each predetermined period and outputs the result. Details of the output device 3 will be described later.

[0033] The operation device 4 is a device that accepts various input operations by a user. The output device 3 may perform various processes according to the various input operations accepted by the operation device 4. The display device 5 is a device that displays various information. The display device 5 may display output results based on various processes by the output device 3.

[0034] The operation device 4 and the display device 5 may be provided in the output device 3. The operation device 4 and the display device 5 may be realized as an integrated device such as a touch panel. The display device 5 may be any device capable of presenting the output result of the output device 3 to the user. For example, the output system 1 may be provided with a printing device that prints the output result of the output device 3 instead of the display device 5. In this case, the user can recognize the output result of the output device 3 by the printed matter printed by the printing device instead of the display screen.

[0035] [Output device] 1, the output device 3 includes, for example, a control unit 31 and a storage unit 32. The control unit 31 comprehensively controls each unit of the output device 3. The control unit 31 includes, for example, a list acquisition unit 311, an operation acquisition unit 312 (acquisition unit), a priority order determination unit 313, a list update unit 314, a second calculation unit 315, a leveling processing unit 316, a health evaluation unit 317, and an output unit 318.

[0036] The list acquisition unit 311 acquires the device list D21. In this embodiment, the list acquisition unit 311 acquires the device list D21 from the management device 2 which is an external device of the output device 3.

[0037] The operation acquisition unit 312 acquires data based on an input operation accepted by the operation device 4. The operation acquisition unit 312 acquires these values ​​when an input operation of, for example, the upper limit of renewal project cost, the renewal cycle, the renewal cost, or the renewal consideration period is accepted via the operation device 4. In other words, the upper limit of renewal project cost, the renewal cycle, the renewal cost, and the renewal consideration period are values ​​that can be set or changed by the input operation.

[0038] The priority order determination unit 313 determines the priority order to be set for each of the multiple devices. The priority order is the order in which the leveling unit 316 selects devices when leveling the renewal project costs. The leveling unit 316 adds the renewal costs associated with the devices in order of priority during any period of the renewal consideration period.

[0039] The priority order determination unit 313 includes, for example, an association unit 331, a read unit 332, a first calculation unit 333, and a setting unit 334.

[0040] The matching unit 331 matches question data D31, which includes a plurality of questions prepared in advance for each facility including at least one device, for evaluating whether the facility functions safely, with the devices included in the equipment list D21.

[0041] The name of an equipment included in the equipment list D21 managed by the management device 2 may differ from the name of an equipment associated with multiple questions included in the question data D31. That is, for the same equipment in the same facility, the name of the equipment given when the equipment list D21 is created may differ from the name of the equipment given when multiple questions are created.

[0042] This is because the creator of the equipment list D21 is different from the creator of the question data D31. For example, the equipment list D21 is created by a facility operator or a contractor commissioned by the operator. This operator or contractor may be a user who uses the output system 1. On the other hand, the question data D31 is created by, for example, a management organization (e.g., the Ministry of Health, Labor and Welfare) that manages multiple operators. Therefore, when calculating the evaluation score by the output device 3, it is necessary to associate the questions with the equipment included in the equipment list D21 by associating the names of the equipment included in the equipment list D21 with the names of the equipment used in the question data D31.

[0043] However, the question data D31 may include questions set by the business operator or the contractor as described above.

[0044] In this specification, the equipment used in the question data D31 is referred to as "equipment" in order to distinguish it from the "equipment" included in the equipment list D21 for convenience. Fig. 2 is a table showing an example of the name of the equipment used in the question data D31.

[0045] The "equipment" in the question data D31 may include at least one of the "equipment" included in the equipment list D21. That is, the equipment in the question data D31 may be the same equipment as the equipment included in the equipment list D21, or may be a collective term for multiple equipment included in the equipment list D21. Furthermore, the equipment in the question data D31 may be equipment composed of multiple equipment included in the equipment list D21. Furthermore, the equipment included in the equipment list D21 may refer not only to equipment arranged in a facility, but also to parts constituting the equipment arranged in the facility (parts arranged in the facility), or may refer to equipment composed of multiple equipment arranged in the facility (equipment arranged in the facility).

[0046] The association unit 331 creates master data D32 that associates the devices included in the device list D21 with the facilities used in the question data D31. The master data D32 created by the association unit 312 is stored in the storage unit 32. Fig. 3 is a diagram showing an example of the master data D32 displayed by the display device 5 (an example of a screen (image) displaying the master data D32).

[0047] In this embodiment, the association unit 331 reflects the first type data and the second type data included in the equipment list D21 as an equipment family, an equipment family name, an equipment type, and an equipment type name, as shown in Fig. 3. When a selection operation for selecting one of the multiple numbers shown in "equipment classification" is accepted via the operation device 4, the association unit 312 associates the names of the facility and equipment associated with the number (the information shown in Fig. 2) with the equipment family and equipment type, as shown in Fig. 3. In this way, the association unit 331 associates the names of the facility and equipment with all the equipment families and equipment types included in the equipment list D21, thereby associating the equipment with the equipment.

[0048] The association unit 331 can associate the equipment with the questions corresponding to the equipment by creating master data D32 that associates the equipment with the facilities. The association unit 331 creates a chart sheet D33 for each equipment based on this association. The chart sheet D33 is a sheet that can reflect the results of an investigation into the equipment included in the equipment list D21.

[0049] The medical record sheet D33 includes, for example, data in which various data related to the equipment included in the equipment list D21 is associated with questions corresponding to the equipment. For equipment for which an evaluation score has been calculated, the medical record sheet D33 reflects the answer results to the questions, the evaluation score based on the answer results, and the total of the evaluation scores (total score). The evaluation score is an example of an evaluation index for the safety of the equipment. In addition, the medical record sheet D33 may include information on the person who investigated the equipment (the person who answers the questions), the date of the investigation, and the number of years since the equipment was installed. The result calculated by the association unit 331 of "(investigation date) - (installation date)" may be reflected in the medical record sheet D33 as the number of years elapsed.

[0050] Fig. 4 is a diagram showing an example of a device data list screen displayed by the display device 5. The device data list screen is a screen that displays a list of various data related to the device, and displays various information entered in the chart sheet D33 for each device. As shown in Fig. 4, based on the information entered in the chart sheet D33, the output unit 318 can display on the display device 5, as various data, for example, information acquired from the device list D21, the most recent survey date, the most recent evaluation score, and the number of evaluations for which the evaluation score was calculated.

[0051] The reading unit 332 reads out question data D31 corresponding to the target device by accepting a selection operation of the target device for which the evaluation points are to be calculated. In this embodiment, when an input operation is accepted on the medical record input button B11 in a state where one device is selected via the operation device 4 on the device data list screen in FIG. 4, the reading unit 332 reads out the medical record sheet D33 of the selected device from the storage unit 32. This selected device becomes the target device for which the evaluation points are to be calculated. By this reading, the output unit 318 can display a medical record input screen corresponding to the target device on the display device 5. The medical record input screen is a screen that can display multiple questions associated with the device. FIG. 5 is a diagram showing an example of a medical record input screen displayed by the display device 5.

[0052] FIG. 4 shows an example in which a selection operation is accepted for the name of the device "Ko-ku simple water reservoir". In FIG. 4, the selected state is indicated by shading. "Ko-ku simple water reservoir" refers to a Ko-ku reservoir in a simplified water supply system. In the following explanation, "Ko-ku simple water reservoir" is referred to as "Ko-ku reservoir". In FIG. 4, when an input operation is accepted for the chart input button B11 with "Ko-ku reservoir" selected, the display device 5 displays a chart input screen for "Ko-ku reservoir" as shown in FIG. 5. In the example of FIG. 5, the target device for which the evaluation points are calculated is "Ko-ku reservoir".

[0053] The first calculation unit 333 calculates an evaluation score for each of the multiple devices. The first calculation unit 333 accepts a selection operation of one of multiple evaluation categories set in stages for each of multiple questions about the target device, and calculates an evaluation score for the target device based on the judgment score associated with the selected evaluation category.

[0054] Fig. 6 is a table showing an example of the question data D31. Fig. 6 shows a part of the question data D31 prepared for pump equipment. As shown in Fig. 6, in the question data D31 for each equipment, a plurality of questions are associated with a plurality of evaluation categories. In this embodiment, each of the plurality of questions is associated with one of a plurality of evaluation items (classifications).

[0055] The evaluation items are items for evaluating whether the facility functions safely, and at least one question related to each item is set. That is, a plurality of questions are classified into a plurality of evaluation items. In this embodiment, five evaluation items are set: "water quality," "water volume / water pressure," "aging," "earthquake / crisis management," and "maintenance management." However, the types of evaluation items are not limited to these.

[0056] The evaluation category indicates a plurality of evaluation contents prepared in advance for a question. In this embodiment, five evaluation contents are set in stages for each question as the evaluation category. One of them, "not applicable," means that it is not included in the calculation of the evaluation points. For example, the following four evaluations may be set in stages in order of the highest evaluation. · No particular problems were identified in managing the operation of the equipment. No problems that would interfere with driving. -Minor impairment may occur, possibly resulting in reduced functionality. - There is a problem that is causing a decrease in functionality and may result in the functionality ceasing. Furthermore, the "special items" shown in FIG. 6 may reflect the questions and evaluation categories set by the business operator or contractor to evaluate the functions of the equipment.

[0057] FIG. 7 is a diagram showing the relationship between the evaluation category and the judgment score. The judgment score is a score set for the evaluation category to calculate the evaluation score. In the example of FIG. 7, except for the evaluation category of "not applicable", the evaluation categories are set with higher judgment scores in the order of higher evaluation. Therefore, the question data D31 also includes judgment scores associated with each evaluation category. In this example, four evaluation categories are set for one question except for "not applicable", and judgment scores of "3", "2", "1" and "0" are set for the evaluation categories with higher evaluations.

[0058] As shown in Fig. 5, one question and an evaluation category corresponding to the question are displayed on the medical record input screen. When an operation to select one evaluation category is received on the medical record input screen via the operation device 4, the first calculation unit 333 stores a judgment score corresponding to the evaluation category. In the example of Fig. 5, the evaluation category with the highest evaluation (the evaluation category with a hatched pattern) is selected, so a judgment score of "3" is displayed.

[0059] 5, the chart input screen is provided with a forward / back button B21. Every time an input operation to the forward / back button B21 is received via the operation device 4, the output unit 318 can cause the display device 5 to display a plurality of questions corresponding to the target devices one by one.

[0060] In this embodiment, the first calculation unit 333 calculates an evaluation score of the target equipment for each evaluation item. In this embodiment, the first calculation unit 333 calculates an evaluation score of the target equipment for each evaluation item of "water quality," "water volume / water pressure," "aging," "earthquake / crisis management," and "maintenance." The first calculation unit 333 calculates an evaluation score of the target equipment each time a survey is conducted on the target equipment (as a result of receiving an operation to select an evaluation category for each question corresponding to the target equipment). The evaluation scores calculated by the first calculation unit 333 are stored in the memory unit 32 for each equipment.

[0061] The first calculation unit 333 calculates, for example, the following evaluation formula: Evaluation score = 100-(3-lowest evaluation score) x 25-(M-1) x 5 The first calculation unit 333 calculates the evaluation score according to the above formula. The minimum evaluation score is one of the evaluation scores "0", "1", and "2". M is the number of minimum evaluation scores for each evaluation item. However, in this example, the maximum value of M is set to 5. For example, when the maximum number of questions for each evaluation item is 6, if the number of minimum evaluation scores is 5 or 6, the first calculation unit 333 inputs 5 into M. If the number of minimum evaluation scores "0" is 5 or 6, the first calculation unit 333 calculates the evaluation score to be 5 points based on the above evaluation formula.

[0062] The first calculation unit 333 does not calculate the evaluation score for questions with a judgment score of "N." Furthermore, in the case where the judgment scores for all questions in each evaluation item are 3 points, the first calculation unit 333 calculates the evaluation score without any deductions, that is, as 100 points in the above evaluation formula. If the minimum judgment score includes any of "0," "1," and "2," the evaluation score is calculated as any of 5 points, 10 points, 15 points, ..., 70 points, or 75 points.

[0063] As shown in FIG. 5, the output unit 318 outputs the evaluation score of the target device calculated by the first calculation unit 333 to the display device 5, thereby making it possible to display the evaluation score of the target device on the medical record input screen.

[0064] The setting unit 334 sets the priority order in ascending order of the device's evaluation points. The setting unit 334 sets the priority order for each device so that the leveling processing unit 316 can preferentially select devices (so that the priority order is higher) in ascending order of the device's evaluation points. The setting unit 334 sets the priority order for all devices included in the device list D21. The setting unit 334 stores the priority order set for each device in the storage unit 32.

[0065] In this embodiment, the setting unit 334 uses the total of the evaluation points for each evaluation item calculated in one survey to set the priority order. When evaluation points have been calculated multiple times for one device, the setting unit 334 sets one of the multiple evaluation points as the evaluation point for that device. In this embodiment, the setting unit 334 sets, for example, the total of the evaluation points calculated in the most recent survey out of the multiple evaluation points as the evaluation point for that device.

[0066] When there are two or more devices with the same evaluation points, the setting unit 334 sets the priority order of these devices based on a predetermined condition. In this way, even when there are two or more devices with the same evaluation points, the setting unit 334 can set different priority orders for the devices. In this embodiment, the setting unit 334 sets the priority order according to any one of the following orders (1) to (3). (1) In descending order, the value calculated by subtracting the update cycle from the number of years since installation; (2) Oldest installation date; (3) In order of lowest renewal cost.

[0067] In this embodiment, the setting unit 334 sets the priority order for two or more devices with the same evaluation points such that the leveling processing unit 316 can select devices with higher priority the larger the value of (1) above. For two or more devices with the same value in (1) above, the setting unit 334 sets the priority order such that the leveling processing unit 316 can select devices with older installation dates in (2) above. For two or more devices with the same installation date in (2) above, the setting unit 334 sets the priority order such that the leveling processing unit 316 can select devices with lower renewal costs in (3) above.

[0068] In this embodiment, the setting unit 334 sets the priority order by applying the above conditions (1), (2), and (3) in this order, but the order of application of the conditions is not limited to this. Also, the priority order may be set using conditions other than the above conditions (1) to (3).

[0069] Furthermore, at the time when the setting unit 334 sets the priority order, there may be devices that have never been surveyed (devices for which the first calculation unit 333 has not calculated an evaluation point; unevaluated devices). In this case, the setting unit 334 sets a provisional evaluation point as the evaluation point of the device. When there are multiple devices that have never been surveyed, the setting unit 334 sets a uniform evaluation point (e.g., 500 points) as the provisional evaluation point. Since the setting unit 334 sets a uniform evaluation point for these devices, the priority order of these devices is set based on the predetermined conditions (the above conditions (1) to (3) in this embodiment) as described above.

[0070] However, for these devices, the setting unit 334 sets a lower priority than surveyed devices (devices for which the first calculation unit 333 has calculated evaluation points; evaluated devices). For example, the setting unit 334 sets a lower priority than surveyed devices with a total evaluation point of 500 points.

[0071] That is, in this embodiment, the setting unit 334 sets the priority order for evaluated devices such that the lower the evaluation score, the higher the device. For two or more devices with the same evaluation score, the setting unit 334 sets different priorities using the above-mentioned predetermined condition. For unevaluated devices, the setting unit 334 sets the priority order so that the device is lower than all evaluated devices. Furthermore, for unevaluated devices, the setting unit 334 sets different priorities using the above-mentioned predetermined condition. For example, if the lowest priority order set for evaluated devices is 300th place, the setting unit 334 sets different priorities for unevaluated devices, which are 301st place or lower.

[0072] The list update unit 314 updates the device list D21. Fig. 8 is a table showing an example of the device list D21. As shown in Fig. 8, in the device list D21, for example, an update period, an update cost, a repair cost, and an inspection cost are set for each device. The update cost, the repair cost, and the inspection cost are in units of thousand yen. For example, the update cost "300" in Fig. 8 means 300,000 yen.

[0073] In this embodiment, a plurality of types of update periods may be set as the update period. As shown in Fig. 8, in this embodiment, first to third cycle patterns are set as the plurality of types of update periods.

[0074] The first cycle pattern refers to the statutory useful life. The statutory useful life is the legally set useful life of the equipment. The statutory useful life is set with a margin from the viewpoint of safety, and is set about ten or so years to several decades shorter than the number of years from the start of use until the time when it is estimated that the equipment will actually malfunction.

[0075] The second cycle pattern refers to the unique useful life. The unique useful life is the useful life of the equipment that is set by the user. From the perspective of reducing renewal costs, the unique useful life is set under the user's responsibility to a number of years that is as close as possible to the number of years until the equipment is estimated to malfunction while ensuring safety.

[0076] The third cycle pattern refers to the number of years for the life extension plan. The number of years for the life extension plan is also the useful life of the equipment that is set by the user. The number of years for the life extension plan is set to a number longer than the user's own useful life while ensuring safety under the user's responsibility.

[0077] As shown in FIG. 8, in the device list D21, the update cycle and / or update fee may not be set for some devices. For example, if the update cycle and / or update fee is not set, the control unit 31 may not be able to calculate the update project fee and may not be able to level the update project fee. Therefore, prior to the calculation or leveling of the update project fee, the list update unit 314 determines whether all of the multiple types of update cycles and update fee values ​​are set for each device. If the list update unit 314 determines that there is an update cycle or update fee for which no value is set, it sets a predetermined value as the update cycle or update fee.

[0078] As a result, the renewal period and renewal cost are preset for each of the multiple devices when the second calculation unit 315 calculates the renewal project cost and when the leveling unit 316 levels the renewal project cost. In this embodiment, multiple renewal periods are preset as the renewal period.

[0079] If the repair cycle and / or repair cost are not set in the equipment list D21, and if the inspection cycle and / or inspection cost are not set, the list update unit 314 may set predetermined values ​​for the items that are not set.

[0080] Furthermore, if the installation date is not set in the equipment list D21, the control unit 31 cannot, for example, calculate the renewal project cost, and cannot perform leveling of the renewal project cost. Therefore, prior to the calculation or leveling of the renewal project cost, the list update unit 314 determines whether there is any equipment in the equipment list D21 for which the installation date is not set. If the list update unit 314 determines that there is at least one equipment for which the installation date is not set, the control unit 31 may notify that the installation date needs to be input. This allows the installation date to be set in advance for each of the multiple equipment when calculating the renewal project cost and when leveling the renewal project cost.

[0081] 9 is a diagram showing an example of the update master data D34 displayed by the display device 5 (an example of a screen displaying the update master data D34). In the update master data D34, a plurality of types of update cycles, update costs, repair costs, and inspection costs are set in advance for each device or each type of device. The names and types of devices in the update master data D34 match the names and types of devices in the device list D21. The update master data D34 may be created by a user who creates the device list D21. In the example of FIG. 9, a plurality of types of update cycles, update costs, and the like are set in advance for each type of device.

[0082] The control unit 31 can accept an input operation to select "update," "repair," or "inspection" via the operation device 4 in "classification" shown on the screen in Fig. 9. When "update" is selected, the output unit 318 causes the display device 5 to display a plurality of types of update cycles (first to third cycle patterns) and the renewal cost, as shown in Fig. 9. When "repair" is selected, the output unit 318 causes the display device 5 to display the repair cycle and the repair cost. When "inspection" is selected, the output unit 318 causes the display device 5 to display the inspection cycle and the inspection cost.

[0083] The list update unit 314 compares the device list D21 with the update master data D34, and inputs values ​​preset in the update master data D34 for the update period, update cost, etc. that are not set in the device list D21. As a result, the update period, update cost, etc. are set for each of all devices included in the device list D21.

[0084] The second calculation unit 315 calculates the renewal project cost corresponding to each of the multiple types of renewal cycles over the renewal consideration period based on the installation date, the multiple types of renewal cycles, and the renewal cost. In this embodiment, the second calculation unit 315 calculates the renewal project cost corresponding to each of the first to third cycle patterns over the renewal consideration period based on the installation date, the first to third cycle patterns, and the renewal cost.

[0085] The second calculation unit 315 adds the update period to the installation date for each device to calculate the year in which the device is to be updated (update year). The second calculation unit 315 calculates the update project cost for each year by adding up the update fee set for each device in the calculated year. The second calculation unit 315 calculates the update project cost for each year during the update consideration period set by the user.

[0086] 10 is a diagram showing an example of a device data list screen displayed by the display device 5. The device data list screen is a screen that displays a list of various data related to devices, and displays, for each device, information such as the update cycle and update cost included in the device list D21 in addition to various information entered in the medical record sheet D33. The information such as the update cycle and update cost may be included in the medical record sheet D33.

[0087] The control unit 31 can accept an input operation to select "update," "repair," or "inspection" via the operation device 4 in "classification" shown on the equipment data list screen in Fig. 10. When "update" is selected, the output unit 318 causes the display device 5 to display a plurality of types of update cycles (first to third cycle patterns) and the renewal cost, as shown in Fig. 10. When "repair" is selected, the output unit 318 causes the display device 5 to display the repair cycle and the repair cost. When "inspection" is selected, the output unit 318 causes the display device 5 to display the inspection cycle and the inspection cost.

[0088] When the device data list screen is displayed, the operation acquisition unit 312 can receive an input operation to change the values ​​of the update period and the update fee via the operation device 4. The values ​​of the update period and the update fee displayed on the device data list screen are one of the following three values. (A) A value preset in the device list D21 (a value included in the device list D21 acquired by the list acquisition unit 311); (B) Values ​​obtained from update master data D34 and entered into equipment list D21; (C) Value entered by input operation.

[0089] The update cycle value for each device and the update cost value for each device included in the device list D21 are associated with data indicating which of the above (A) to (C) they are. Therefore, the output unit 318 outputs the data when outputting the device list D21 or the medical record sheet D33 to the display device 5. This allows the display device 5 to display the update cycle value for each device and the update cost value for each device on the device data list screen so as to distinguish which of the above (A) to (C) they are.

[0090] As shown in FIG. 10, in area A32, the "Device List", "Master" and "Input" areas are each displayed in a different manner. For example, the "Device List", "Master" and "Input" areas may be displayed in different colors. The display manner of the "Device List" in area A32 indicates that the value of the update period or update cost is the value (A) above. The display manner of the "Master" in area A32 indicates that the value of the update period or update cost is the value (B) above. The display manner of the "Input" in area A32 indicates that the value of the update period or update cost is the value (C) above.

[0091] On the device data list screen, the area displaying the update cycle value for each device and the update fee value for each device is displayed in one of the display modes of "Device List", "Master" and "Input" in area A32. In the example of FIG. 10, the "First Periodic Pattern" for device number "KN000002" indicates that the value is (B) above. Also, the "Second Periodic Pattern" for device number "KN000005" indicates that the value is (C) above. The other update cycle and device update fee values ​​indicate that the values ​​are (A) above.

[0092] The repair cycle and repair costs, as well as the inspection cycle and inspection costs, may be displayed in the same manner as the renewal cycle and renewal costs described above.

[0093] The second calculation unit 315 calculates the renewal project cost corresponding to each of the first to third periodic patterns over the renewal consideration period using any of the values ​​(A) to (C) above. Therefore, when the operation acquisition unit 312 accepts an input operation to change the value of the renewal period or the renewal cost, the second calculation unit 315 calculates the renewal project cost corresponding to at least one of the first to third periodic patterns based on at least one of the changed renewal period and renewal cost.

[0094] When the second calculation unit 315 receives an input operation that causes the second calculation unit 315 to calculate the renewal project cost and an input operation of the renewal consideration period, the second calculation unit 315 reads out the renewal period and renewal cost indicated in the first to third periodic patterns for all equipment included in the equipment list D21.

[0095] In this embodiment, a case is considered in which an input operation is accepted on the calculation button B31 in a state in which the start year and end year of the renewal consideration period are input in the period input area A31 via the operation device 4 on the device data list screen of Fig. 10. In this case, the second calculation unit 315 reads out from the storage unit 32 the renewal cycles and renewal costs for all devices included in the device list D21.

[0096] The period input area A31 is an area capable of accepting input of the start year and end year of the renewal consideration period. The calculation button B31 is a button capable of accepting an input operation for causing the second calculation unit 315 to calculate the renewal project cost. Then, the second calculation unit 315 calculates the renewal project cost for each year over the input renewal consideration period for each of the first to third periodic patterns.

[0097] If the control unit 31 receives an input operation on the calculation button B31 when the start year and / or end year have not been entered in the period input area A31, the control unit 31 may notify the user that the start year and / or end year must be entered.

[0098] 11 to 14 are tables and graphs showing an example of the calculation results of the renewal project cost for each year in the renewal review period for each of the first to third periodic patterns, the cumulative value of the renewal project cost up to each year, and the average value of the renewal project cost in the renewal review period. In this embodiment, the second calculation unit 315 calculates the renewal project cost for each year, the cumulative value of the renewal project cost from the start year of the renewal review period to each year, and the average value of the renewal project cost in the renewal review period.

[0099] Fig. 11 is a table showing an example of the calculation results, cumulative values, and average values ​​of renewal project costs for each of the first to third periodic patterns. Fig. 12 is a graph showing an example of the calculation results, cumulative values, and average values ​​of renewal project costs for the first periodic pattern. Fig. 13 is a graph showing an example of the calculation results, cumulative values, and average values ​​of renewal project costs for the second periodic pattern. Fig. 14 is a graph showing an example of the calculation results, cumulative values, and average values ​​of renewal project costs for the third periodic pattern.

[0100] In the examples of Figures 11 to 14, the start year of the renewal consideration period is set to 2023, and the end year is set to 2062. In the graphs of Figures 12 to 14, the horizontal axis indicates each year (elapsed time) of the renewal consideration period, and the vertical axis indicates the renewal project cost and cumulative value.

[0101] As shown in Figs. 11 to 14, it can be seen that the transition of the renewal project cost differs depending on the first to third periodic patterns. Therefore, it can be seen that the cumulative value and the average value also differ depending on the first to third periodic patterns. The second output unit 382 described later displays the calculation results, cumulative value and average value of the renewal project cost for each of the first to third periodic patterns on the display device 5, so that the user can understand the transition of the renewal project cost which differs from one another in each periodic pattern. Furthermore, the transition of the renewal project cost in each periodic pattern also changes depending on the change in the renewal period and / or renewal cost.

[0102] The leveling processing unit 316 levels out the renewal project costs over the renewal consideration period based on the installation date, renewal cycle, and renewal cost preset for each of the multiple devices so that the renewal project costs are equal to or less than the upper limit value acquired by the operation acquisition unit 312. The leveling processing unit 316 includes, for example, an addition unit 361 and a determination unit 362.

[0103] The addition unit 361 adds the renewal cost in a first period of the renewal consideration period based on the installation date and renewal cycle in the order of priority set for the equipment by the setting unit 334. The determination unit 362 determines whether the renewal project cost in the first period has exceeded the upper limit. If the renewal project cost exceeds the upper limit, the addition unit 361 adds the renewal cost added in the first period in a second period different from the first period instead of the first period.

[0104] The addition unit 361 adds (allocates) the renewal cost to the fiscal year (first period) in which the renewal cycle is added to the installation date for the device with the highest priority, i.e., the device with the highest priority for adding the renewal cost. In each fiscal year, the renewal project cost before the renewal cost is added is 0. Therefore, when the renewal cost is added (allocated) for the first time in each fiscal year, the renewal cost becomes the renewal project cost for that fiscal year.

[0105] The determination unit 362 determines whether the renewal project cost for the year to which the addition unit 361 added the renewal cost has exceeded the upper limit. When the determination unit 362 determines that the renewal project cost for the year does not exceed the upper limit, the addition unit 361 adds the renewal cost for the year (first period) in which the renewal period is added to the installation date for the device with the next highest priority. The determination unit 362 determines whether the renewal project cost for the year has exceeded the upper limit. The addition unit 361 and the determination unit 362 repeat this process until the determination unit 362 determines that the renewal project cost for the year to which the addition unit 361 added the renewal cost has exceeded the upper limit.

[0106] Then, consider a case where the determination unit 362 determines that the renewal project cost for a year to which the addition unit 361 added the renewal cost at a certain point in time has exceeded the upper limit. In this case, the addition unit 361 deletes the renewal cost added in the year from the year, and adds the renewal cost in a year (second period) different from the year. The determination unit 362 determines whether the renewal project cost for the different year has exceeded the upper limit as a result of adding the renewal cost in the different year.

[0107] If the determination unit 362 determines that the renewal project cost for another year does not exceed the upper limit, the addition unit 361 and the determination unit 362 perform processing for the equipment with the next highest priority after the equipment to which the renewal cost was added at a certain point in time. If the determination unit 362 determines that the renewal project cost for another year exceeds the upper limit, the processing by the addition unit 361 and the determination unit 362 is repeated until the determination unit 362 determines that the renewal project cost to which the renewal cost is added does not exceed the upper limit.

[0108] In this way, the process by the addition unit 361 and the determination unit 362 is repeated until the renewal cost of the device with the lowest priority, i.e., the device with the lowest priority for adding renewal costs, is added to the corresponding fiscal year. That is, the process by the addition unit 361 and the determination unit 362 is performed in order from the device with the highest priority to the device with the lowest priority. In this way, the leveling processing unit 316 can level the renewal project costs in the renewal consideration period so as not to exceed the upper limit value. In addition, since the priority is set so that the lower the evaluation point, the higher the priority, the leveling processing unit 316 can prioritize the renewal time of the device that is estimated to be more deteriorated, and then level the renewal project costs.

[0109] In this embodiment, the separate year is the year following the year for which the renewal fee was added. However, the separate year may be the year preceding the year for which the renewal fee was added. In addition, if the renewal project cost exceeds the upper limit in the separate year after the next year is set as the separate year, the year preceding the year for which the renewal fee was initially added may be set as the separate year.

[0110] Furthermore, when the leveling processing unit 316 adds the renewal cost to the other year, it may add the renewal cost of the equipment with the next highest priority to the year to which the renewal cost was added. In this case, if the renewal project cost for the year does not exceed the upper limit even if the renewal cost of the equipment with the next highest priority is added to the year to which the renewal cost was added, the leveling processing unit 316 adds the renewal cost of the equipment with the next highest priority to the year.

[0111] Furthermore, the leveling processor 316 may perform further leveling processing when the renewal project cost for a certain year is lower than the adjacent renewal project cost by a predetermined value or more. For example, the leveling processor 316 may add the renewal project cost for equipment that meets all of the following conditions to the year that is lower by a predetermined value or more. ·The renewal fee is added to the year relatively close to the year that is lower by a certain amount; ·Adding the above renewal fees to the year lower than the specified value does not exceed the upper limit; Even if the above renewal costs are subtracted from the year in which they were added, the renewal project cost for the year in which they were subtracted will not be lower than the adjacent renewal project cost by more than a specified amount.

[0112] The above-mentioned predetermined value and the range of years to which renewal fees that can be added are assigned may be determined, for example, by user settings.

[0113] In this way, the leveling processor 316 postpones the addition of the renewal cost to a year after the year to which the renewal cost was added so that the renewal project cost for each year does not exceed the upper limit. Alternatively, the leveling processor 316 advances the addition of the renewal cost to a year before the year to which the renewal cost was added so that the renewal project cost for each year does not exceed the upper limit.

[0114] FIG. 15 is a diagram showing an example of an update year list screen displayed by the display device 5. The update year list screen is a screen that displays the update year for each device. In the example of FIG. 15, in addition to various data such as the name of the device included in the device list D21, information on the installation date, update cost, and priority used in the leveling process, as well as the first update year and the last update year are displayed for each device. The first update year and the last update year may be the result calculated from the installation date and update period preset in the device list D21, or may be the update year changed by the leveling process. The leveling processing unit 316 stores the update year of each device after leveling in the storage unit 32.

[0115] The control unit 31 can accept an input operation to select "update," "repair," or "inspection" via the operation device 4 in "classification" shown on the update year list screen in Fig. 15. Fig. 15 is an example of a display screen when "update" is selected. When "repair" is selected, the output unit 318 causes the display device 5 to display, for example, the repair year in which the repair will be performed (e.g., the first repair year and the last repair year) and the repair cost. When "inspection" is selected, the output unit 318 causes the display device 5 to display, for example, the inspection year in which the inspection will be performed (e.g., the first inspection year and the last inspection year) and the inspection cost.

[0116] On the update year list screen, the above values ​​(A) to (C) are also displayed in a differentiated manner in the display format shown in area A32.

[0117] When the leveling processing unit 316 receives an input operation for causing the leveling processing unit 316 to level the renewal project costs and an input operation for the renewal consideration period, the leveling processing unit 316 reads out the renewal cycles and renewal costs for all devices included in the device list D21 from the storage unit 32. When the leveling processing unit 316 receives an input of an upper limit value for the renewal project costs, it reads out the renewal cycles and renewal costs.

[0118] In this embodiment, consider a state in which the start year and end year of the renewal consideration period are input in the period input area A31 and the upper limit of the renewal project cost is input in the upper limit input area A41 via the operation device 4 on the renewal year list screen in Fig. 15. In this state, when an input operation to the leveling button B41 is accepted, the leveling processing unit 316 reads out from the storage unit 32 the renewal periods and renewal costs for all the devices included in the device list D21.

[0119] The upper limit input area A41 is an area that can accept input of the upper limit of the renewal project cost for one year. The operation acquisition unit 312 acquires the upper limit of the renewal project cost accepted in the upper limit input area A41. The leveling button B41 is a button that can accept an input operation that causes the leveling processing unit 316 to level the renewal project cost. When an input operation to the leveling button B41 is accepted, the leveling processing unit 316 uses the read renewal cycle and renewal cost to level the renewal project cost over the input renewal consideration period so that it is below the acquired upper limit. In this embodiment, the leveling processing unit 316 uses the statutory useful life (first cycle pattern) as the renewal cycle.

[0120] When the control unit 31 receives an input operation to the leveling button B41 in a state where the start year and / or end year have not been input in the period input area A31, the control unit 31 may notify the user that a start year and / or end year is required to be input. Also, when the control unit 31 receives an input operation to the leveling button B41 in a state where an upper limit value has not been input in the upper limit value input area A41, the control unit 31 may notify the user that an upper limit value is required to be input.

[0121] FIG. 16 is a table showing an example of the transition of the renewal project cost after leveling and the cumulative value. FIG. 17 is a graph showing an example of the transition of the renewal project cost after leveling and the cumulative value. The renewal project cost after leveling shown in FIG. 16 and FIG. 17 is the result of leveling the renewal project cost over the renewal review period based on the statutory useful life. The cumulative value shown in FIG. 16 and FIG. 17 is the cumulative value of the renewal project cost after leveling up to each year. In this embodiment, the leveling processing unit 316 calculates the cumulative value of the renewal project cost from the start year of the renewal review period to each year in addition to leveling the renewal project cost. In FIG. 16, the "renewal project cost after leveling" is shown as "project cost (leveling)" and the "cumulative value" is shown as "project cost (leveling) cumulative total". FIG. 17 is a graph of the renewal project cost after leveling and the cumulative value shown in FIG. 16.

[0122] In the examples of Figures 16 and 17, the start year of the renewal consideration period is set to 2023, and the end year is set to 2062. The upper limit of renewal project costs is set to 200 million yen. In the graph of Figure 17, the horizontal axis indicates each year (elapsed time) of the renewal consideration period, and the vertical axis indicates renewal project costs and cumulative values.

[0123] As shown in Fig. 17, it can be seen that the renewal project costs are leveled out compared to the calculation results of the second calculation unit 315 shown in Fig. 12. In addition, by appropriately changing the upper limit value, the fiscal year in which the renewal project costs are added changes, and therefore the trend in the renewal project costs also changes.

[0124] The health evaluation unit 317 evaluates the health of the equipment for each year based on the installation date and the legal useful life of the equipment. In this embodiment, for example, three patterns of health are set in descending order of health: "healthy", "aging", and "deteriorated".

[0125] The health evaluation unit 317 evaluates the health of equipment whose age is within the legal useful life in the target year for which the health is evaluated as "healthy". The health evaluation unit 317 evaluates the health of equipment whose age is within 1.0 to 1.5 times the legal useful life in the target year as "aging". The health evaluation unit 317 evaluates the health of equipment whose age is more than 1.5 times the legal useful life in the target year as "aging".

[0126] 18 and 19 are graphs showing an example of the transition of the health of equipment. FIG. 18 is a graph showing the transition of the health of equipment calculated based on the update year of each equipment before leveling. FIG. 19 is a graph showing the transition of the health of equipment calculated based on the update year of each equipment after leveling. In the graphs of FIG. 18 and FIG. 19, the horizontal axis indicates each year (elapsed time) during the update consideration period. Also, the vertical axis indicates the ratio of the number of equipment whose health is evaluated as "healthy", the number of equipment whose health is evaluated as "aging", and the number of equipment whose health is evaluated as "deteriorating" to the total number of equipment.

[0127] As shown in Figures 18 and 19, the transition of the equipment health level is different before and after leveling. This is because the fiscal year in which the renewal costs are added changes due to the setting of the upper limit, and the equipment health level for each fiscal year also changes. Therefore, by appropriately changing the upper limit, the transition of the equipment health level also changes.

[0128] Figure 16 is a table showing an example of the trend in renewal project costs by health level. In Figure 16, "healthy assets (no renewal)" is the total value for each fiscal year of renewal costs for equipment with a health level of "healthy" before leveling, and "healthy assets (with renewal)" is the total value for each fiscal year of renewal costs for equipment with a health level of "healthy" before leveling, and "aging assets (with renewal)" is the total value for each fiscal year of renewal costs for equipment with a health level of "aging" before leveling, and "aging assets (with renewal)" is the total value for each fiscal year of renewal costs for equipment with a health level of "aging" before leveling, and "aging assets (with renewal)" is the total value for each fiscal year of renewal costs for equipment with a health level of "aging" before leveling, and "aging assets (with renewal)" is the total value for each fiscal year of renewal costs for equipment with a health level of "aging" before leveling, and

[0129] For example, the leveling unit 316 allocates the renewal cost for each fiscal year according to the health of the equipment evaluated by the health evaluation unit 317, thereby obtaining the transition of the renewal project cost shown in Fig. 16. Since the fiscal year for adding the renewal cost changes according to the change in the upper limit, the transition of the renewal project cost for each health also changes.

[0130] The output unit 318 outputs various data to the display device 5. The output unit 318 transmits, for example, an equipment list D21 to the display device 5. This enables the display device 5 to display a screen for creating master data D32 as shown in Fig. 3. The output unit 318 transmits, for example, a medical record sheet D33 to the display device 5. This enables the display device 5 to display an equipment data list screen as shown in Fig. 4 and a medical record input screen as shown in Fig. 5.

[0131] The output section 318 includes, for example, a first output section 381 and a second output section 382.

[0132] The first output unit 381 outputs the renewal project cost over the renewal consideration period that has been leveled by the leveling processing unit 316 to the display device 5. This allows the display device 5 to display a graph showing the renewal project cost and the accumulated value over time as shown in Fig. 18. The display device 5 can display a table showing the renewal project cost and the accumulated value by year as shown in Fig. 16.

[0133] The second output unit 382 outputs the renewal project cost for each year over the renewal consideration period calculated by the second calculation unit 315 for each of the first to third periodic patterns. This allows the display device 5 to display tables and graphs showing the calculation results, cumulative values, and average values ​​of the renewal project cost as shown in Figs. 11 to 14.

[0134] The output unit 318 outputs the renewal cost of each device and the renewal year of each device obtained by leveling to the display device 5. This allows the display device 5 to display the renewal cost of each device and the renewal year of each device after leveling. The renewal cost of each device used at the time of leveling (the renewed renewal cost if changed) and the renewal year of each device obtained by leveling are stored in the storage unit 32, so that the output unit 318 can output this information to the display device 5. Therefore, the control unit 31 can store the renewal cost and renewal year finally determined by the user in the storage unit 32 and output them to the display device 5. Then, the display device 5 can display a renewal year list screen as shown in FIG. 15.

[0135] The output unit 318 outputs the health assessed by the health assessment unit 317 to the display device 5. This allows the display device 5 to display graphs showing the progress of the equipment health as shown in Fig. 18 and Fig. 19. Furthermore, the output unit 318 outputs the result of the leveling processing unit 316 allocating the renewal cost for each equipment health, allowing the display device 5 to display a table showing the progress of the renewal project cost for each health as shown in Fig. 16.

[0136] As described above, the leveling processing unit 316 levels the renewal project cost over the renewal consideration period based on the upper limit value set by the input operation. Then, the first output unit 381 displays the leveled renewal project cost as shown in FIG. 17 on the display device 5. This allows the user to recognize whether the renewal project cost has been leveled as desired based on the trend of the displayed renewal project cost. If the renewal project cost has not been leveled as desired, the user resets the upper limit value by input operation. This causes the control unit 31 to obtain the reset upper limit value, level the renewal project cost again over the renewal consideration period based on the upper limit value, and display the leveled renewal project cost again on the display device 5.

[0137] Therefore, the control unit 31 can optimize the renewal project costs over the renewal consideration period as desired by the user by obtaining an upper limit value through input operations and outputting renewal project costs leveled based on the upper limit value.

[0138] In this embodiment, as described above, the second output unit 382 causes the display device 5 to display the calculation results, cumulative values, and average values ​​of the renewal project costs as shown in Figs. 11 to 14 for each of the first to third periodic patterns. Therefore, the user can determine the upper limit value of the renewal project costs to be used for leveling after comparing and examining the trends of multiple renewal project costs. Therefore, the user can easily determine the upper limit value that is estimated to be preferable for leveling at an early stage.

[0139] Furthermore, the second output unit 382 causes the display device 5 to display the renewal project cost based on the renewed renewal cycle and / or renewal cost each time the renewal cycle and / or renewal cost are changed. Therefore, the second output unit 382 can cause the display device 5 to display various patterns of renewal project costs for each of the first to third cycle patterns. Therefore, the user can determine the upper limit value of the renewal project cost through various simulations.

[0140] Furthermore, the output unit 318 causes the display device 5 to display the transition of the health evaluated by the health evaluation unit 317 (the transition of the health as shown in FIG. 19). Therefore, the user can recognize whether the transition of the health is the desired transition from the displayed transition of the health. If the transition of the health is not as desired, the user can reset the upper limit value by inputting operation, and the control unit 31 will evaluate the health of each device using the renewal year of each device identified again by leveling, and display the transition of the evaluated health on the display device 5. Therefore, the user can set the upper limit value so as to obtain the desired transition of the renewal project cost while also recognizing the transition of the health.

[0141] For example, a user may recognize that the trend in health is the desired trend if, in each year, the percentage of equipment whose health is evaluated as “healthy” is relatively high and the percentage of equipment whose health is evaluated as “aging” or “deteriorating” is relatively low.

[0142] In this way, the user can adjust the upper limit value as appropriate so that the trend in renewal project costs becomes the desired trend, while referring to the calculation results for each of the first to third periodic patterns and the evaluation results of the soundness as a result of leveling out the renewal project costs.

[0143] The storage unit 32 stores various data used by the control unit 31. As shown in Fig. 1, the storage unit 32 stores, for example, question data D31, master data D32, a chart sheet D33, and updated master data D34. The storage unit 32 stores the question data D31 prepared for each device, and the chart sheet D33 created for each device.

[0144] In addition, the storage unit 32 stores, for example, the device list D21 acquired from the management device 2. When the list update unit 314 updates the values ​​of the device list D21, the updated device list D21 is stored in the storage unit 32. The storage unit 32 also stores various values ​​set or changed based on an input operation, the evaluation points for each device calculated by the first calculation unit 333, the priority order for each device set by the setting unit 334, and the result of leveling by the leveling processing unit 316. The leveling result may include the update year of each device after leveling.

[0145] The output device 3 does not need to include the storage unit 32. In this case, the output system 1 may include the storage unit 32 as a storage device that can be communicatively connected to the output device 3.

[0146] [Control method of output device] 20 and 21 are flowcharts showing an example of the flow of processing by the control unit 31. In FIG.

[0147] <Priority setting process> Fig. 20 is a flowchart showing an example of a priority setting process performed by priority order determination section 313. In Fig. 20, it is assumed that the process performed by association section 331 has been completed.

[0148] In the priority order determination unit 313, first, the reading unit 332 reads out the chart sheet D33 of the target device selected by the input operation (S1). The control unit 31 causes the display device 5 to display a chart input screen and accepts the selection operation of the evaluation category for all questions set for the target device. The first calculation unit 333 calculates the evaluation score of the target device based on the selected evaluation category (S2).

[0149] The priority order determination unit 313 determines whether the first calculation unit 333 has calculated the evaluation points for all devices (S3). The priority order determination unit 313 repeats the processes of S1 and S2 until the calculation of the evaluation points for all devices is completed (NO in S3). When the priority order determination unit 313 determines that the calculation of the evaluation points for all devices is completed (YES in S3), the setting unit 334 sets the priority order in ascending order of the evaluation points for the devices (S4).

[0150] At this time, the setting unit 334 judges whether there are two or more devices with the same evaluation points (S5). If the setting unit 334 judges that there are two or more devices with the same evaluation points (YES in S5), it sets priorities for these devices according to the predetermined conditions as described above (S6). The setting unit 334 repeats the processes of S5 and S6 until there are no more two or more devices with the same evaluation points.

[0151] As a result, different priorities are set for all devices included in the device list D21. If there are not two or more devices with the same evaluation points, the priority order determination unit 313 ends this process (NO in S5).

[0152] <Processing up to outputting the levelized renewal project costs> 21 is a flowchart showing an example of a series of processes in which the control unit 31 smoothes out the renewal project costs over the renewal consideration period and outputs the smoothed renewal project costs. The flow of this process shows an example of a control method for the output device 3.

[0153] The control unit 31 first determines whether the operation device 4 has received an input operation of an upper limit value of the renewal project cost (S11). The control unit 31 waits until it receives an input operation of an upper limit value of the renewal project cost (NO in S11). When the control unit 31 determines that the operation device 4 has received an upper limit value of the renewal project cost (YES in S11), the operation acquisition unit 312 acquires the upper limit value of the renewal project cost (S12; acquisition step).

[0154] The control unit 31 also determines whether the operation device 4 has received an input operation for the update consideration period (S13). The control unit 31 waits until the input operation for the update consideration period is received (NO in S13). When the control unit 31 determines that the operation device 4 has received an input operation for the update consideration period (YES in S13), the operation acquisition unit 312 acquires the update consideration period (S14; acquisition step).

[0155] In this embodiment, the input operation of the upper limit of the renewal project cost and the renewal consideration period is accepted in a state where the renewal year list screen shown in Fig. 15 is displayed. The order of processing S11 and S12 and S13 and S14 does not matter.

[0156] Next, the leveling processing unit 316 levels out the renewal project costs so that the renewal project costs for each year in the input renewal consideration period are below the input upper limit of the renewal project costs (S15; leveling processing step).

[0157] In this embodiment, the leveling processor 316 adds the renewal cost to the corresponding year according to the priority order set for each device. If the renewal project cost exceeds the upper limit in the year to which the renewal cost was added, the leveling processor 316 deletes the renewal cost added to the year and adds the renewal project cost to another year. The leveling processor 316 repeats this process. In addition, if the renewal project cost of a certain year is lower than the renewal project cost of an adjacent year by a predetermined value or more, the leveling processor 316 may further level the renewal project cost by transferring the renewal cost from another year to the certain year.

[0158] The first output unit 381 outputs the renewal project cost for each year after the leveling to the display device 5 (S16; first output step). As a result, the display device 5 displays the renewal project cost for each year after the leveling. In this embodiment, the display device 5 displays the renewal project cost for each year after the leveling as a graph as shown in FIG.

[0159] [Other configuration examples] The above-mentioned judgment points and evaluation formulas are merely examples. It is sufficient that judgment points and evaluation formulas are prepared according to the number of questions and / or the number of evaluation categories set so that the evaluation points can be calculated to reflect the evaluation according to the actual degree of deterioration of the target device.

[0160] Also, the evaluation points do not have to be calculated for each evaluation item. For example, the evaluation points may be calculated based on the judgment points for questions set in two or more evaluation items. That is, one evaluation point may be calculated for an evaluation item group including a plurality of evaluation items. This includes the calculation of evaluation points based on the judgment points for all questions set in the target device. In this case, as described above, it is sufficient that the judgment points and evaluation formulas are prepared according to the number of questions and / or the number of evaluation categories set.

[0161] Furthermore, the setting unit 334 may not set the priority order of each device using the total score (total score) of the evaluation points for each evaluation item calculated in one survey. The setting unit 334 may set the priority order of each device using the evaluation points of specific evaluation items set in advance. When two or more evaluation items (excluding all evaluation items) are set as the specific evaluation items, the setting unit 334 may set the priority order of each device using the total score of the two or more evaluation items.

[0162] The second calculation unit 315 may also calculate the renewal project cost for each year using a renewal cycle set for each device other than the statutory useful life, the unique useful life, and the life extension measure years (first to third cycle patterns). A plurality of cycle patterns other than the above three cycle patterns may be prepared. The control unit 31 may set a cycle pattern other than the above three patterns by replacing the unique useful life and / or the life extension measure years of each device, for example.

[0163] In the processing of the leveling unit 316 and the health evaluation unit 317, a unique useful life or a life extension measure number of years may be used instead of the statutory useful life.

[0164] The control unit 31 may add the repair cost and the inspection cost to the leveled renewal project cost. In this case, the first output unit 381 may output data in which the repair cost and the inspection cost are added to the leveled renewal project cost to the display device 5. This allows the display device 5 to display the transition of the leveled renewal project cost in a state in which the repair cost and the inspection cost are added.

[0165] [Major effects of the output device and its control method] As described above, the control unit 31 can optimize the renewal project cost over the renewal consideration period as desired by the user by acquiring the upper limit value through input operations and outputting the renewal project cost leveled based on the upper limit value. Therefore, the financial burden for the renewal project cost for each fiscal year can be leveled.

[0166] In this embodiment, the control unit 31 outputs the results of leveling the renewal project cost, the calculation results for each of the first to third periodic patterns, and the evaluation results of the soundness to the display device 5. Therefore, the user can appropriately adjust the upper limit value so that the renewal project cost changes as desired, while referring to this information displayed on the display device 5. Therefore, the control unit 31 can optimize the renewal project cost as desired by the user by simply having the user perform a simple operation, without causing the user unnecessary trouble.

For example, an integrated circuit in which a logic circuit that functions as each of the control blocks is formed is also included in the scope of the present invention. In addition, the functions of each of the control blocks can be realized by, for example, a quantum computer.
