Description

  The present invention relates to a periodic inspection planning apparatus system and method for creating a periodic inspection schedule for a machine.

  In recent years, parts supplied for manufactured products by air transportation etc. are imported from overseas or ordered from within Japan. If there is a sudden breakdown of parts, it must be ordered by air. However, since this is costly, it is more efficient to detect a sign of failure in advance and replace the parts during periodic inspection.

  For example, Patent Document 1 describes a device that supports a stop plan during a periodic inspection. Schedule the periodic inspection schedule when it is time to formulate a fixed equipment outage plan or when temporary work occurs. Calculate the failure rate of the equipment based on the operation data of the equipment (the number of abnormalities in the past and the age of the equipment). If the failure rate is high, shorten the number of days until the next periodic inspection. If the failure rate is low If you can postpone it, set a longer number of days.

JP 2002-32440 A

  However, in the technique described in Patent Document 1, when the next periodic inspection date is set based on the failure rate, it is not considered whether the inspection company can perform the inspection on that day. It is unclear whether the inspection plan can be performed according to the planned schedule because the number of inspectors is insufficient or the facility to be inspected is inconvenient.

  In order to solve the above problems, one embodiment of the present invention includes the following configuration. That is, a periodic inspection schedule storage unit that stores the time of the normal periodic inspection schedule of the parts and the time of the early inspection schedule that is a certain time before the time of the normal periodic inspection schedule, and the lifetime that stores the lifetime of the parts A data storage unit, a component life estimation unit that predicts the time of the last repair time of a component as the life of the component, and the life before the time of the regular periodic inspection schedule, and further from the time of the early inspection schedule If it is within the later period, a regular repair plan information creating unit that changes the normal periodic inspection schedule so as to inspect within the period is provided.

  According to the present invention, an inspection plan can be presented.

  Hereinafter, the best mode for carrying out the present invention will be described with reference to the drawings.

  An embodiment of the present invention will be described with reference to FIGS. In the present embodiment, a system is assumed in which a user makes a periodic repair plan, presents a correction plan for the periodic repair plan by estimating the life of parts, and gives an operation instruction for additional work at the time of periodic repair. However, this does not limit the present invention, and the system makes a machine condition determination from the measurement data to estimate the life of the parts, and presents a correction plan for the periodic repair plan together with the cost effectiveness required for the correction. Even in the situation, the embodiments of the present invention are applicable.

  FIG. 1 is a configuration diagram in one usage pattern of a periodic inspection planning apparatus 100 that displays a correction plan of a periodic repair plan in the best mode for carrying out the present invention. The periodic inspection planning apparatus 100 includes a periodic repair plan information creation unit 101, a component life estimation unit 102, a plan change cost calculation unit 103, a work instruction unit 104, a control unit 107, an input / output unit 108, and a periodic repair plan. The database 109, the site convenience information database 110, the personnel assignment database 111, the measurement data database 112, the component life database 113, and the repair cost database 114 are configured.

  The periodic repair plan information creation unit 101 plans a schedule for periodic repair of the machine. The component life estimation unit 102 estimates the component lifetime from the measurement data of the machine component. For example, the time obtained by adding the lifetime to the previous repair time of the component may be predicted as the lifetime of the component. It is assumed that the component lifetime is registered in advance in the component lifetime database 113 for each component. The plan change cost calculation unit 103 creates a change plan for the periodic repair schedule from the life of the parts and calculates the cost effect when the change plan is executed. The work instructing unit 104 plans which parts the operator carries with the schedule changed when the periodic repair schedule is changed, and instructs the input / output unit 108 to display the planned information.

  In addition, you may implement | achieve these function parts by software by interpreting the program which implement | achieves the function which the periodic inspection planning apparatus 100 of a present Example has. Information of a program that realizes each function may be stored in an appropriate storage device (memory or the like) 106 of the system, and may be read and executed by the control unit 107 including a CPU that is an arithmetic device.

  Further, the input / output unit 108 inputs information related to selection of the changed periodic inspection schedule from the user, and outputs information including the time and cost of the periodic inspection schedule to the user, or inspection parts of each worker. . Further, the periodic repair plan database 109 stores a time that is a starting point when a schedule for periodic repair is established, an interval time between periodic repairs, and an actual (after change) schedule. The on-site convenience information database 110 stores data indicating a time zone in which a site where periodic repair is performed can respond to the periodic repair. The personnel assignment database 111 stores work schedule data for each worker in order to assign workers to perform periodic repairs. The measurement data database 112 stores measurement data such as temperature and pressure of machine parts. The component lifetime database 113 stores component lifetime data estimated based on measurement data. The repair cost database 114 stores cost data required for repairing parts (incorporation into emergency or regular repairs).

  The database including the periodic repair plan database 109, the site convenience information database 110, and the personnel allocation database 111 is referred to as the periodic repair basic database 115, and the database including the measurement data database 112, the part life database 113, and the repair cost database 114 is repaired as a life part. The database 116 is assumed.

  Next, the details of the regular repair basic database 115 and the life product repair database 116 will be described.

  FIG. 2 shows an example of the periodic repair plan database 109. The regular repair plan database 109 is composed of a regular repair start point table 200 that is the date and time when the machine first started operation, a regular repair interval table 210 that is a regular periodic inspection schedule time, and a regular repair schedule table 220. The periodic repair starting point table 200 is a table indicating the date and time that is the starting point of the periodic repair interval that is performed at regular intervals, and includes a site ID 201, a device ID 202, a manufacturing number 203, and a periodic repair starting point 204. The site ID 201 stores an ID indicating the site of the site where the machine that is subject to periodic repair is installed.

  The device ID 202 stores the product code of the machine that is subject to periodic repair. The production number 203 stores a machine production number for identifying an individual machine subject to periodic repair. The periodic repair starting point 204 stores the date and time when the machine subject to the periodic inspection first started to operate as the starting point of the periodic inspection.

The periodic repair interval table 210 includes a device ID 211, an elapsed time 212, a replacement part ID 213, and an allowable time 214. The device ID 211 stores the product code of the machine that is subject to periodic repair. The elapsed time 212 stores a measure of the elapsed time from the periodic repair starting point 204 when performing periodic repair. Thus, the elapsed time is the time from the start of the machine to the end of its life.
The replacement part ID 213 stores the product code of the part that is subject to periodic repair. The allowable time 214 stores a time during which a change in the start time of the periodic repair is permitted after the periodic repair schedule is determined.

  The allowable time 214 is fixed, and a time during which the start time of the periodic repair is allowed is input by a customer or salesperson who knows the situation of the site (when it can be stopped). However, it may be changed every moment according to the situation at the site. For example, if the business hours of a store or the hours of operation of a factory are registered in the inspection planning apparatus 100 and it is found in advance that a temporary closure or temporary shutdown will occur, the temporary closure or temporary shutdown will occur. Since it is considered that there is no problem even if the machine is stopped, it may be allowed to be closed or not in operation. By re-registering the business hours and operating hours that have been changed due to temporary closures and temporary shutdowns in the inspection planning device 100, the inspection planning device 100 automatically changes the allowable time due to temporary closures or temporary shutdowns. It is also possible to re-register at the permissible time 214 after calculation.

  The periodic repair schedule table 220 includes a site ID 221, a device ID 222, a production number 223, a scheduled stop start time 224, a scheduled stop end time 225, an elapsed time 226, and a replacement part ID 227. The site ID 221 stores an ID indicating the site of the site where the machine that is subject to periodic repair is installed. The device ID 222 stores the product code of the machine that is subject to periodic repair. The production number 223 stores a machine production number for identifying an individual machine that is subject to periodic repair. The scheduled stop start time 224 stores a scheduled stop start time when the machine is stopped for periodic repair. The scheduled stop end time 225 stores a scheduled stop end time when the machine is stopped for periodic repair.

  In the elapsed time 226, an indication of the elapsed time from the periodic repair starting point 204 when performing periodic repair is stored. The replacement part ID 227 stores the product code of the part that is subject to periodic repair. The periodic repair schedule table 220 is created based on the periodic repair starting point table 200, the periodic repair interval table 210, and a site convenience information database 110 described later.

  In this way, information including the time of the normal periodic inspection schedule for parts and the time of the early inspection schedule, which is a time before the time of the normal periodic inspection schedule, is stored in the database.

  FIG. 3 shows an example of the site convenience information database 110. The site convenience information database 110 includes a site ID 301, a device ID 302, a serial number 303, a stop start possible time 304, a stop end possible time 305, a stop penalty / hour 306, and a stop schedule 307. The site ID 301 stores an ID indicating the site of the site where the machine that is subject to periodic repair is installed. The device ID 302 stores the product code of the machine that is subject to periodic repair.

  The production number 303 stores a machine production number for identifying an individual machine that is subject to periodic repair. The stop start possible time 304 stores the first time during which the machine can be stopped for periodic repair. In the stop-end possible time 305, the last time during which the machine can be stopped for periodic repair is stored. Information on the stop start possible time 304 and the stop end possible time 305 may be input by, for example, a customer who knows the situation at the site (when it can be stopped) or a salesperson.

  In the stop penalty / hour 306, when the machine is stopped between the stop start possible time 304 and the stop end possible time 305, a penalty per unit time (1 hour) paid to the customer who operates the machine is set. Store. The scheduled stop 307 indicates whether or not there is a plan to stop the machine between the stop start possible time 304 and the stop end possible time 305, and stores “present” and “none”.

  FIG. 4 shows an example of the personnel assignment database 111. The personnel allocation database 111 includes a name code 401, a site ID 402, a device ID 403, a scheduled work start time 404, and a scheduled work end time 405. The name code 401 stores a code indicating an operator to whom work for repair (periodic repair, emergency repair) is assigned. The site ID 402 stores an ID indicating the site where the work is performed.

  The device ID 403 indicates a machine on which work is performed. The scheduled work start time 404 stores the scheduled work start time. The scheduled work end time 405 stores the scheduled work end time. Information about the scheduled work start time 404 and the scheduled work end time 405 may be input by a person in charge who plans regular repairs, for example. Since the number of workers at a certain time can be calculated from the scheduled work start time 404 and the scheduled work end time 405, it is determined whether a new worker can be assigned at that time. it can.

  FIG. 5 shows an example of the measurement data database 112. The measurement data database 112 includes a site ID 501, a device ID 502, a production number 503, a component ID 504, a temperature 505, a pressure 506, and a measurement time 507. The site ID 501 indicates the ID of the site where the measurement target machine is installed. The device ID 502 indicates the product code of the measurement target machine. The production number 503 indicates a production number for individual identification of the measurement target machine. The part ID 504 indicates the product code of the part of the machine to be measured. A temperature 505 indicates measurement data when a part of a measurement target machine is measured by a temperature sensor. A pressure 506 indicates measurement data when a machine part to be measured is measured by a pressure sensor. The measurement time 507 indicates the time when the temperature 505 and the pressure 506 are measured.

  FIG. 6 shows an example of the component life database 113. The component lifetime database 113 is a database that stores the lifetime of components estimated based on the measurement data database 112. The site ID 601 indicates the ID of a site where a machine composed of parts whose lifetime is estimated is installed. The device ID 602 indicates a product code of a machine configured with parts whose lifetime is estimated. A production number 603 indicates a production number of a machine including parts whose lifetime is estimated. The part ID 604 indicates the product code of the part whose life is estimated. The life time 605 indicates the life of the component whose life is estimated, and is calculated from the temperature 505, the pressure 506, and the like. The life time 605 is a time obtained by adding the life time to the time of the previous repair of the part.

  FIG. 7 shows an example of the repair cost database 114. The site ID 701 stores an ID indicating a site at a site where a machine to be repaired (periodic repair, emergency failure repair) is installed. The device ID 702 stores the product code of the machine to be repaired. The part ID 703 stores the product code of the machine part to be repaired. The expense item 704 stores the type of repair. “Emergency breakdown repair” is stored when the machine has failed and stopped and indicates repair that requires urgent action, and “periodic repair built-in” is stored when it indicates that the machine is to be repaired by repairing it. Cost 705 stores the cost required for repair.

Next, the creation of periodic repair plan information in the present embodiment will be described.
FIG. 8 shows a processing flow in creating periodic repair plan information. Control of this process flow is performed by the control unit 107, and processes other than the process S800 are performed by the periodic repair plan information creating unit 101.

  In step S800, the user operates the input / output unit 108 of the periodic inspection planning apparatus 100 to start an application for creating periodic repair plan information. By this processing, the periodic repair plan information creation unit 101 is activated. It is assumed that the regular repair plan by this process is made periodically, for example, once a month.

  In the process S801, the periodic repair starting point 204 of the machine installed at each site is acquired from the periodic repair starting point 204 of the periodic repair starting point table 200 of the periodic repair plan database 109.

  In process S802, a record in which the device ID 202 matches the device ID 211 is searched in the periodic repair interval table 210, and the elapsed time 212 is acquired as the elapsed time until the periodic repair.

  In the process S803, of the elapsed time acquired in the process S802, at the time that is the starting point of the periodic repair acquired in the process S801 from the present (when the periodic repair plan is created) to the time when the next periodic repair plan information is created. It is determined whether there is a time (periodic repair candidate time) obtained by adding the elapsed times acquired in step S802. In this way, it is determined whether or not there is a plan to perform periodic repairs from the time when the periodic repair plan is created until the next periodic repair is created. If it exists, the process S804 and the process S805 are performed for all the scheduled repair candidate times, and if not, the process proceeds to the process S806.

  In the process S804, the period from the periodic start possible time 304 to the stop ending possible time 305 in the on-site convenience information database 110 is regarded as a stoppable time, and is as close as possible to the scheduled repair candidate time calculated in the process S803. The database 111 searches the time zone from the scheduled work start time 404 to the scheduled work end time 405 in the database 111 and a time zone in which a necessary number of workers can be secured without suffering. The required number of persons increases when the number of records (number of parts) of the replacement part ID 213 having the same device ID 211 and elapsed time 212 is large, and decreases when the number of records is small. Further, the number of people may be decreased if the stoppable time is long, and the number of people may be increased if the stoppable time is short. For example, a table including the necessary number of persons corresponding to the work may be registered in advance, the work necessary for the periodic inspection may be extracted, and the total number of persons corresponding thereto may be calculated as the necessary number of persons.

  In the process S805, the stoppable time period searched in the process S804 is set as the periodical repair period, and is registered in the periodical repair schedule table 220 of the periodical repair plan database 109. At the time of registration, the scheduled stop start time 224 is the scheduled repair start time, the scheduled stop end time 225 is the scheduled repair end time, the site ID 221 is the site ID 201, the device ID 222 is the device ID 202, and the manufacturing number. 223 is the manufacturing number 203, the elapsed time 226 is the elapsed time 212, and the replacement part ID 227 is the replacement part ID 213. In addition, the stop schedule 307 corresponding to the stoppable time in the time period between the stoppable start time 304 and the stoppable end time 305 of the site convenience information database 110 is changed from “none” to “present”.

  In the process S806, it is searched whether the processes from the process S801 to the process S805 have been completed for all the records in the regular repair start point table 200 (whether all regular repair candidate times have been completed). If completed, the process proceeds to step S807. If not completed, the process advances to step S801 for the site ID 201, device ID 202, and serial number 203 that have not been completed. In step S807, the control unit 107 ends the process for creating periodic repair plan information.

Next, correction of the regular repair plan based on the component life in the present embodiment will be described.
FIG. 9 shows a processing flow until the periodic repair plan is corrected. It is assumed that the control unit 107 performs control of this processing flow.

  In process S900, the user activates a business application for periodic repair plan correction based on the component life. With this processing, the component life estimation unit 102, the plan change cost calculation unit 103, and the work instruction unit 104 are activated. The main activation is performed once at the beginning, and thereafter, the business application is always activated.

  In process S901, the component life estimation unit 102 estimates the life time of the component ID 504 of the product ID 503 of the device ID 502 of the site ID 501 based on the temperature 505, the pressure 506, and the measurement time 507 of the measurement data database 112.

  The life time is estimated as follows, for example. The machine designer records in advance in the database the part ID and the average life time until failure. Also, at the start of machine operation, the installation operator records the operation start date in the database so as to correspond to each part ID of the machine. During operation, the control unit 107 records the operation time periodically sent from the machine in the database. The control unit 107 estimates the life time by adding the time obtained by subtracting the operation time from the average life time to the current time.

  The estimated lifetime is stored at the lifetime time 605 of the component lifetime database 113, the site ID 501 is stored in the site ID 601, the device ID 502 is stored in the device ID 602, the manufacturing number 503 is stored in the manufacturing number 603, and the component is stored in the component ID 604. ID 504 is stored.

  In process S902, the planned change cost calculation unit 103 determines whether the service life is after the start time of the scheduled repair stored in the scheduled repair plan database 109, based on the service life of the parts estimated in process S901. The determination is made based on whether or not the life time 605 of the part ID 604 of the production number 603 of the device ID 602 of the corresponding site ID 601 is later than the scheduled stop start time 224 of the periodic repair schedule table 220 of the periodic repair plan database 109.

  Regarding the search for the scheduled stop start time 224, the site ID 601 matches the site ID 221, the device ID 602 matches the device ID 222, the manufacturing number 603 matches the manufacturing number 223, and the part ID 604 matches the replacement part ID 227. Assume that the scheduled stop start time 224 is searched. The number of rows of the record of the scheduled stop start scheduled time 224 is stored in the storage device 106. If the life time 605 is later than or equal to the scheduled stop start time 224, the process proceeds to step S908, and if it is before, the process proceeds to step S903.

  In the process S903, the plan change cost calculation unit 103 determines whether the service life is later than the time (the earliest periodic repair start time) that the service life is advanced by an allowable time from the start time of the regular repair based on the life of the parts estimated in the process S901. ,judge. The determination is made that the life time 605 of the part ID 604 of the production number 603 of the device ID 602 of the corresponding site ID 601 is the allowable time 214 of the periodic repair interval table 210 from the scheduled stop start time 224 of the periodic repair schedule table 220 of the periodic repair plan database 109. Judge by whether it is later than the earlier time.

  The scheduled stop start time 224 is the scheduled stop start time 224 of the number of rows of records stored in the storage device 106 in step S902. Regarding the search for the allowable time 214, the device ID 222 of the record matches the device ID 211 of the periodic repair interval table 210, the elapsed time 226 matches the elapsed time 212, and the replacement part ID 227 matches the replacement part ID 213. And The storage device 106 stores the earliest scheduled repair start time and allowable time 214. If the life time 605 is later than or equal to the earliest periodic repair start time (time earlier than the scheduled stop start time 224 by the allowable time 214), the process proceeds to the next process S904, and if it is the previous time, the process proceeds to the process S907. As described above, when the service life is before the time of the normal periodic inspection schedule and within the period after the time of the early inspection schedule, the normal periodic inspection schedule is changed so that the inspection is performed within the period. Also good.

  In the process S904, the plan change cost calculation unit 103 acquires the earliest periodic repair start time stored in the storage device 106, and the site convenience information database in a time zone later than the earliest periodic repair start time and earlier than the part life. 110 and the personnel assignment database 111 determine whether the scheduled repair schedule can be reconfigured.

  In the determination, first, the site ID 221 and the site ID 301 of the record in the periodic repair schedule table 220 included in the earliest scheduled scheduled repair start time coincide with the site ID 301 in a time zone later than the earliest scheduled repair start time and earlier than the part life. It is searched in the field convenience information database 110 whether or not the record between the ID 222 and the device ID 302 and the serial number 223 and the serial number 303 includes the time zone between the stop start possible time 304 and the stop end possible time 305. To do.

  When not included, it progresses to process S907. If it is included, in the personnel assignment database 111, the site ID 221 matches the site ID 402, the device ID 403 matches the device ID 302, and the time between the scheduled work start time 404 and the scheduled work end time 405 is earlier than the scheduled periodic repair start time. The number of name codes 401 of workers who include a time zone that is late and earlier than the life of the part is counted (records relating to workers engaged in this periodic repair are excluded from the count).

  If the number of the name codes 401 of the workers is equal to the maximum number of workers who can work at this time, it is determined that the scheduled repair schedule cannot be reconfigured, and the process proceeds to step S907. If the number is less than the maximum number, it is determined that the scheduled repair schedule can be reassembled, and the time period less than the maximum number is stored in the storage device 106 as the scheduled repair incorporation candidate time period, and the process proceeds to step S905.

  In step S905, the plan change cost calculation unit 103 creates a correction plan for periodic repair and estimates the cost. When creating a correction plan for periodic repair and estimating the cost, a periodic repair correction plan screen (see FIG. 10) is output to the input / output unit. The draft for periodic repair is prepared as follows.

  First, the current periodic repair plan is acquired from the periodic repair schedule table 220. The site ID 221, device ID 222, serial number 223, scheduled stop start time 224, scheduled stop end time 225, elapsed time 226, and replacement part ID 227 are acquired from the periodic repair schedule table 220. Here, the temporary repair cost and the periodic repair cost are searched in the repair cost database 114 and the on-site convenience information database 110.

  The temporary repair cost is the cost of the repair cost database 114 in which the site ID 701 matches the site ID 221, the device ID 702 matches the device ID 222, the part ID 703 matches the replacement part ID 227, and the cost item 704 matches “emergency failure repair”. Obtained as 705.

  The periodic repair cost is a record in which the site ID 301 matches the site ID 221, the device ID 302 matches the device ID 222, the manufacturing number 303 matches the manufacturing number 223, and the scheduled stop 307 is “Yes”. The stop penalty / time 306 of the record in the on-site convenience information database 110 including the time zone between the scheduled stop start time 224 and the scheduled stop end time 225 in the time zone from the stop stop possible time 305 is acquired, and the stop penalty is acquired. A value obtained by multiplying the value of / hour 306 by the time between the scheduled stop start time 224 and the scheduled stop end time 225 is acquired as the periodic repair cost.

  Next, data (periodic repair incorporation cost, periodic repair cost) necessary for displaying the proposed periodic repair plan after the change is searched in the repair cost database 114, the part life database 113, and the site convenience information database 110. The periodic repair built-in costs include a repair cost database 114 in which the site ID 701 matches the site ID 221, the device ID 702 matches the device ID 222, the part ID 703 matches the replacement part ID 227, and the cost item 704 matches “periodic repair built-in”. Is acquired as the cost 705 of the record.

  The periodic repair costs are the time period from the stop start possible time 304 to the stop end possible time 305, with the site ID 301 matching the site ID 221, the device ID 302 matching the device ID 222, and the manufacturing number 303 matching the manufacturing number 223. The stop penalty / hour 306 of the record in the on-site convenience information database 110 including the time zone between the start time and the end time of the scheduled repair incorporation candidate time zone stored in the storage device 106 in step S804 is acquired, and the stop penalty is obtained. A value obtained by multiplying the value of / hour 306 by the time between the start time and end time of the regular repair incorporation candidate time zone is acquired as the periodic repair cost after the change.

  In process S906, the user operates the periodic repair correction plan screen (see FIG. 10) output to the input / output unit 108, and selects whether to perform temporary repair or confirm the change of the periodic repair plan. 103 obtains. If it is determined that temporary repair is to be performed, the process proceeds to step S907. In the case of confirming the change of the periodic repair plan, the correction plan for the periodic repair created in step S905 is reflected in the periodic repair plan database 109 and the site convenience information database 110. Specifically, the scheduled start time 224 and scheduled stop end time 225 of the scheduled repair schedule table 220 in the scheduled repair plan database 109 are overwritten with the start time and end time of the scheduled repair incorporation candidate time zone.

  In addition, the stop schedule 307 is overwritten with “present” with respect to a record in which the time period from the stop start possible time 304 to the stop end possible time 305 of the on-site convenience information database 110 includes the scheduled repair incorporation candidate time period. When the process for changing the periodic repair plan is completed, the work instruction unit 104 outputs the next periodic repair plan screen (see FIG. 11) to the input / output unit 108. After the user confirms the instruction on the screen and presses the confirmation end button, the work instruction unit 104 ends this processing and proceeds to processing S908.

  In process S907, the user performs temporary repair (emergency failure repair).

  In step S908, the work instruction unit 104 determines whether to end the business application. As long as there is no application error or the like, the business application is not terminated, the temperature and pressure of the machine parts are measured, and the process returns to step S901 when the measurement data database 112 is updated. If the business application is to be terminated, the process proceeds to step S909.

  In step S909, the control unit 107 ends the business application.

The part replacement cost 1023 indicates a part replacement cost that is higher than that of normal periodic repair when a part that has failed is incorporated into the next periodic repair. The replacement part list 1024 shows a list of product codes of parts that are presumed to fail and are incorporated in the next periodic repair. The periodic repair cost 1025 is a cost for stopping the machine and performing periodic repairs, and indicates, for example, a penalty to be paid to the customer when the machine is stopped. The total cost 1016 indicates the total cost required for the periodic repair plan after the change. In this example, the total is the part replacement cost 1023 and the periodic repair cost 1025.

  The temporary repair execution button 1030 is a button that is pressed when the user performs temporary repair, and is pressed when performing temporary repair without changing the schedule of the periodic repair plan. The change confirmation button is a button that the user presses when changing the schedule of the periodic repair plan from the pre-change 1010 to the post-change 1020, and is pressed when the schedule of the periodic repair plan is changed and no temporary repair is performed.

The next periodic repair plan screen displayed in step S906 is, for example, the screen shown in FIG.
FIG. 11 includes periodic repair information 1101 and a confirmation end button 1105. The periodic repair information 1101 includes device information 1102, a scheduled date and time 1103, and a replacement part list 1104. Device information 1102 indicates information on a device to be periodically repaired, and displays a site ID, a device ID, a manufacturing number, and the like. The scheduled date and time 1102 indicates the scheduled date and time for the next periodic repair. Display the start date and time and end date and time of regular repairs. The replacement part list 1104 shows a list of product codes of parts to be replaced at the time of periodic repair. A confirmation end button 1105 is a button to be pressed when the user ends confirmation of the periodic repair instruction on this screen.

  In the server-client system, the periodic inspection planning apparatus 100 other than the input / output unit 108 is in the server system, only the input / output unit 108 is in the client system, and the server system and the client system communicate information via the network. It is also good. By remotely accessing the periodic inspection planning apparatus 100, which is a server system, from the input / output unit 108, which is a client system, the input / output unit 108 can be placed at each site. Thereby, it becomes possible to flexibly change the data to be input to the periodic inspection planning apparatus 100 according to the situation of each site. For example, it is possible to calculate extraordinary expenses according to on-site data.

  This embodiment makes it possible to present an inspection plan including cost effectiveness. As a result, the user can select whether to perform an extraordinary repair, to confirm a change in the regular repair plan, or to consider cost effectiveness.
