It is realized by a contact input circuit, a voice input circuit, and the like. In the present embodiment, the input interface 110 is not limited to the one provided with physical operating parts such as a mouse and a keyboard. For example, an example of the input interface 110 includes an electric signal processing circuit that receives an electric signal corresponding to an input operation from an external input device provided separately from the device and outputs the electric signal to a control circuit.

The display 120 is connected to the processing circuit 150 and displays various information and various images. Specifically, the display 120 converts various information and various image data sent from the processing circuit 150 into electrical signals for display and outputs the data. For example, the display 120 is realized by a liquid crystal monitor, a CRT (Cathode Ray Tube) monitor, a touch panel, or the like.

The processing circuit 150 controls the components of the information processing device 100. For example, the processing circuit 150 executes the estimation function 151, the search function 152, the calculation function 153, and the output processing function 154. Here, for example, each processing function executed by the estimation function 151, the search function 152, the calculation function 153, and the output processing function 154, which are the components of the processing circuit 150, is stored in the form of a program that can be executed by a computer. It is recorded in 140. The processing circuit 150 is a processor that realizes a function corresponding to each program by reading each program from the storage circuit 140 and executing the program.

The word "processor" used in the above description includes, for example, a CPU (Central Processing Unit), a GPU (Graphics Processing Unit), an integrated circuit for a specific application (Application Specific Integrated Circuit: ASIC), and a programmable logic device (for example, a programmable logic device). It means a circuit such as a simple programmable logic device (SPLD), a complex programmable logic device (CPLD), and a field programmable gate array (FPGA). When the processor is, for example, a CPU, the processor realizes a function by reading and executing a program stored in a storage circuit. On the other hand, when the processor is, for example, an ASIC, the program is incorporated directly into the circuit of the processor instead of storing the program in the storage circuit. It should be noted that each processor of the present embodiment is not limited to the case where each processor is configured as a single circuit, and a plurality of independent circuits may be combined to form one processor to realize its function. Good. Further, the plurality of components in FIG. 1 may be integrated into one processor to realize the function.

The overall configuration of the information processing apparatus 100 according to the present embodiment has been described above. Under such a configuration, the information processing device 100 according to the present embodiment performs the following processing so that the hospital side can execute the maintenance request at an appropriate timing. First, the estimation function 151 estimates a failure sign component representing a failure sign and a failure time of the failure sign component based on the states of a plurality of components constituting the medical device 200. The search function 152 searches for the date and time when the maintenance work can be performed by the failure time as the maintenance candidate date and time based on the reservation status of the medical device 200 and the time related to the maintenance work of the failure sign component. The calculation function 153 calculates the maintenance price on the maintenance candidate date and time based on the cost related to the failure sign component and the cost related to the maintenance work. The output processing function 154 presents a failure sign component, a failure time, a maintenance candidate date and time, and a maintenance price.

Next, the process executed by the estimation function 151 will be described. As described above, the estimation function 151 estimates the failure sign component representing the failure sign and the estimated failure time which is the failure time of the failure sign component based on the states of the plurality of components constituting the medical device 200. ..

Specifically, first, the estimation function 151 monitors changes over time as the state of a plurality of parts constituting the medical device 200, and among the plurality of parts, a failure sign component that represents a failure sign. To estimate. For example, each of the plurality of parts is provided with a sensor (not shown). By receiving the sensor data output from the sensor, the estimation function 151 monitors the change over time as the state of the component provided with the sensor. Then, when the sensor data received from the sensor exceeds a predetermined threshold value or falls below a predetermined threshold value, the estimation function 151 estimates the component provided with the sensor as a failure sign component.

For example, the medical device 200 is an "X-ray CT device", and a sensor is provided in an "X-ray tube" which is one of a plurality of parts constituting the "X-ray CT device". And. In this case, the sensor measures the resistance value of the filament of the "X-ray tube" and outputs it as sensor data to the information processing apparatus 100. In the information processing device 100, the estimation function 151 monitors the state of the "X-ray tube" provided with the sensor by receiving the sensor data output from the sensor. For example, the estimation function 151 monitors the change in the resistance value of the filament of the “X-ray tube” provided with the sensor over time by receiving the sensor data output from the sensor. Then, for example, when the resistance value of the filament of the "X-ray tube" is less than a predetermined threshold value, the estimation function 151 estimates the "X-ray tube" as a failure sign component. Further, the estimation function 151 is a failure time of the failure sign component based on the time-dependent change in the resistance value of the filament of the failure sign component "X-ray tube" and the failure history of each component that has occurred in the past. Estimate the failure time and failure probability. Here, the estimation function 151 may estimate the estimated failure time and failure probability in consideration of the usage status of the medical device 200.

As an example of the usage status of the medical device 200, the estimation function 151 monitors temperature, vibration, and the like. For example, at least one of the medical device 200 and the plurality of parts constituting the medical device 200 is provided with a temperature sensor and a vibration sensor, and the estimation function 151 receives sensor data output from the temperature sensor and the vibration sensor. Thereby, the usage status of the medical device 200 is monitored.

FIG. 2 is a diagram showing an example of the failure history DB 141 in the present embodiment. The failure history DB 141 stores information such as a failure history for each component that has occurred in the past. The failure history DB 141 is stored in, for example, a storage circuit 140 or an external server connected to the information processing device 100 via a network. For example, FIG. 2 shows a failure history when the part “X-ray tube” has failed in the past among the failure histories of each part that have occurred in the past. For example, as a failure that has occurred in the past, it is assumed that the resistance value of the filament of the "X-ray tube" gradually decreases with time, and one day, the resistance value falls below a predetermined threshold value. At this time, it is assumed that the "X-ray tube" has failed 13 days after the day when the resistance value falls below the predetermined threshold value. In this case, the resistance value is the lowest at the time of failure. Further, the failure probability increases as the resistance value decreases.

For example, the estimation function 151 estimates the estimated failure time and failure probability from the time course of the resistance value of the filament of the failure sign component "X-ray tube" with reference to the failure history DB 141. Specifically, it is assumed that the resistance value of the filament of the "X-ray tube" gradually decreases with time, and the resistance value falls below a predetermined threshold value on "June 17". In this case, the estimation function 151 estimates "June 30 (13 days later)" as the estimated failure time of the failure sign component "X-ray tube". The failure probability at this time is assumed to be "90%".

Next, the process executed by the search function 152 will be described. As described above, the search function 152 sets a plurality of dates and times on which maintenance work can be performed by the estimated failure time based on the reservation status of the medical device 200 and the time related to the maintenance work of the failure sign component. Search as. Specifically, the search function 152 refers to various DBs and searches for a plurality of maintenance candidate dates and times.

FIG. 3 is a diagram showing an example of the parts inventory DB 142 in the present embodiment. For example, as shown in FIG. 3, the parts inventory DB 142 stores information such as inventory status and parts cost for each part. The parts inventory DB 142 is stored in, for example, a storage circuit 140 or an external server connected to the information processing device 100 via a network. For example, the parts inventory DB 142 is managed by a management company that manages the inventory of parts, and the information in the parts inventory DB 142 is updated when the inventory status, the parts cost, or the like is changed. For example, inventory status is updated when maintenance work is reserved. The inventory status includes the part information that identifies the part, the storage place where the part is stored, and the inventory which is the number of parts stored in the storage place. The part information includes, for example, a part name, a part number, a model number, and the like. The storage location includes location information such as, for example, the name of the warehouse or the address of the warehouse. The search function 152 refers to the parts inventory DB 142 and searches for the inventory status and the parts cost of the substitute parts that are the substitutes for the failure sign parts. For example, the failure sign component is an "X-ray tube" whose model number is "XXX" as component information. Further, the storage location where the "X-ray tube" XXX "" is stored is a warehouse whose location information is "AAA", "BBB", and "CCC". In the storage locations "warehouse" AAA "", "warehouse" BBB "", and "warehouse" CCC "", the inventory of "X-ray tube" XXX "" is "1", "2", and "0", respectively. It is assumed that the number of parts is "X1" and the cost of parts is "X1". In addition, the storage location "warehouse" AAA "" shall be the closest to the transportation destination "hospital A". In this case, the search function 152 refers to the parts inventory DB 142, and sets the storage location “warehouse“ AAA ”” as the inventory status and the parts cost of the alternative parts that are the substitutes for the failure sign parts “X-ray tube“ XXX ””. Search for inventory "1 piece" and parts cost "X1".

FIG. 4 is a diagram showing an example of the parts procurement DB 143 in the present embodiment. For example, as shown in FIG. 4, the parts procurement DB 143 stores information such as the delivery date and transportation cost for each part. The component procurement DB 143 is stored in, for example, a storage circuit 140 or an external server connected to the information processing device 100 via a network. For example, the parts procurement DB 143 is managed by a management company that manages the inventory of parts. The search function 152 searches for the delivery date and transportation cost of the alternative parts with reference to the parts procurement DB 143. Delivery time and transportation cost vary depending on the storage location, transportation destination, and transportation means. In addition, the transportation cost increases as the distance from the storage location to the transportation destination increases. In addition, the transportation cost increases according to the distance, and the labor cost when transporting from the storage location to the transportation destination also increases. For example, when transporting the alternative part "X-ray tube" XXX "" from the storage location "warehouse" AAA "" to the destination "hospital A", the delivery time is "6 days" when using a "truck" as the means of transportation. It is assumed that the transportation cost is "Y1". In addition, when using "airplane" and "truck" as means of transportation (hereinafter referred to as "airplane, truck"), the delivery date shall be "3 days" and the transportation cost shall be "Y2". .. Since the transportation means "airplane + truck" is used when urgent arrangements are required, the transportation cost "Y2" is higher than the transportation cost "Y1". In this case, the search function 152 refers to the parts procurement DB 143 and refers to the delivery date and transportation when the alternative part “X-ray tube“ XXX ”” is transported from the storage location “warehouse“ AAA ”” to the transportation destination “hospital A”. As the cost, the delivery date "6 days" and the transportation cost "Y1" when the "truck" is used as the transportation means are searched. In addition, the search function 152 searches for the delivery date "3 days" and the transportation cost "Y2" when "airplane, truck" is used as the transportation means.

FIG. 5 is a diagram showing an example of the maintenance work DB 144 in the present embodiment. For example, as shown in FIG. 5, the maintenance work DB 144 stores information such as maintenance work time and labor cost required for maintenance work by a worker for each part. The maintenance work DB 144 is stored in, for example, a storage circuit 140 or an external server connected to the information processing device 100 via a network. For example, the maintenance work DB 144 is managed by a management company that manages workers. The search function 152 refers to the maintenance work DB 144 and searches for the maintenance work time and labor cost required for the maintenance work of the failure sign component. Maintenance work time and labor cost vary depending on the content of maintenance work. Maintenance work includes replacement and repair. For example, when the maintenance work is the work of replacing the failure sign component "X-ray tube" XXX "" with a substitute part, the worker goes to "Hospital A" and the maintenance work time required for the maintenance work is "6 hours". , And the labor cost shall be "Z1". In this case, the search function 152 refers to the maintenance work DB 144 and searches for the maintenance work time "6 hours" and the labor cost "Z1" required for the maintenance work of the failure sign component "X-ray tube" XXX "".

FIG. 6 is a diagram showing an example of the worker DB 145 in the present embodiment. For example, as shown in FIG. 6, the worker DB 145 stores information such as a worker's schedule. The worker DB 145 is stored in, for example, a storage circuit 140 or an external server connected to the information processing device 100 via a network. For example, the worker DB 145 is managed by a management company that manages the workers. Since the medical device 200 is installed in a hospital, it is desirable that the maintenance work be performed on holidays, and in the case of weekdays, it is desirable that the maintenance work be performed at night. Therefore, the worker DB 145 can perform maintenance work on a schedule in which the worker can perform maintenance work on holidays and on weekday nights, for example, between 18:00 and 6:00 the next day. Memorize the schedule. In the present embodiment, as an example, a case where a worker performs maintenance work at night on weekdays will be described. For example, "worker A" can perform maintenance work after 18:00 on weekdays, "June 21" is "possible until 3:00 the next day", and "June 24" is " It is assumed that "possible until 3:00 the next day" and "possible until 1:00 the next day" on "June 26". As a schedule on which "worker B" can perform maintenance work after 18:00 on weekdays, "June 25" shall be "possible until 24:00". It is assumed that "June 20th" is "possible until 23:00" as a schedule in which "worker C" can perform maintenance work after 18:00 on weekdays. The search function 152 refers to the worker DB 145 and sets the schedules of "worker A", "worker B", and "worker C" as "worker A", "worker B", and "worker C". Search for dates on which maintenance work can be performed at night.

FIG. 7 is a diagram for explaining a recommended maintenance date in the present embodiment. For example, the search function 152 is a schedule that does not make an emergency arrangement based on the time required for the maintenance work of the failure sign component "X-ray tube" XXX "", and the estimated failure time "June 30 (13 days later)". Search for the shortest schedule for which maintenance work can be performed by "" as the recommended maintenance date. Here, the inventory status (storage location "warehouse" AAA "", inventory "1 piece") and delivery date ("3 days", "6 days") of the alternative part "X-ray tube" XXX "" searched by the search function 152. ), The maintenance work time "6 hours" required for the maintenance work of the failure sign component "X-ray tube" XXX "", and the schedule of "worker A", "worker B", and "worker C". This corresponds to the time required for maintenance work of the failure sign component "X-ray tube" XXX "".

For example, as shown in FIG. 7, the schedule during which the worker can carry out the maintenance work of the maintenance work time "6 hours" after 18:00 on weekdays by the estimated failure time "June 30 (13 days later)" is "Available until 3:00 the next day" on "June 21", "Available until 3:00 the next day" on "June 24", "Available until 24:00" on "June 25", "June 26" "It is possible until 1:00 the next day." Here, when the delivery date of the alternative part "X-ray tube" XXX "" is "6 days", the date of estimating the failure sign by using the "truck" as a means of transportation is "June 17". Six days later, on "June 23", the alternative part "X-ray tube" XXX "" will be transported from the storage location "warehouse" AAA "" to the destination "hospital A". On the other hand, if the schedule is before "June 23", "airplanes and trucks" will be used as the means of transportation, so emergency arrangements will be made and the transportation cost will be high. In this case, the shortest date and time during which maintenance work can be carried out by the estimated failure time "June 30 (13 days later)" is "June 24". That is, the search function 152 sets "June 24" as the recommended maintenance date.

FIG. 8 is a diagram showing an example of the inspection reservation DB 146 in the present embodiment. For example, as shown in FIG. 8, the examination reservation DB 146 stores information such as the reservation status of the medical device 200. The examination reservation DB 146 is stored in, for example, a storage circuit 140 or an external server connected to the information processing device 100 via a network, and is managed by users such as doctors, medical staff, and examination personnel who make examination reservations. To. The inspection reservation is made by the user using the terminal 300. The reservation status of the medical device 200 includes, for example, the reservation date and time of the medical device 200, and in the present embodiment, the reservation of the medical device 200 is made once per hour. For example, in the examination reservation DB 146, as the reservation date and time of the medical device 200, it is assumed that three reservations of the medical device 200 are entered after 18:00 on "June 20" and "June 21" until 21:00. To do. In addition, after 18:00 on "June 24" to "June 26", it is assumed that two reservations for the medical device 200 have been made until 20:00. The search function 152 refers to the examination reservation DB 146 and searches for the reservation status of the medical device 200 up to the estimated failure time "June 30 (13 days later)".

FIG. 9 is a diagram for explaining a maintenance candidate date and time in the present embodiment. For example, the search function 152 uses the estimated failure time "until June 30 (13 days later)" based on the reservation status of the medical device 200 and the time related to the maintenance work of the failure sign component "X-ray tube" XXX "". Search for multiple dates and times when maintenance work can be performed as maintenance candidate dates and times.

For example, as shown in FIG. 6, on the recommended maintenance date "June 24", "worker A" can carry out the maintenance work from 18:00 to 3:00 the next day. Further, as shown in FIG. 5, the maintenance work time is "6 hours" as the time required for the maintenance work of the failure sign component "X-ray tube" XXX "". Further, as shown in FIG. 8, on "June 24", the medical device 200 is reserved from 18:00 to 20:00 as the reservation status of the medical device 200. In this case, on "June 24", the time during which "worker A" can perform the maintenance work of the maintenance work time "6 hours" is "20:00 to 2:00 the next day" as shown in FIG. .. That is, the search function 152 sets "20:00 to 2:00 the next day" of "June 24" as the maintenance candidate date and time.

For example, as shown in FIG. 6, on "June 21st", "worker A" can carry out maintenance work from 18:00 to 3:00 the next day. Further, as shown in FIG. 8, on "June 21st", the medical device 200 is reserved from 18:00 to 21:00 as the reservation status of the medical device 200. In this case, on "June 21st", the time during which "worker A" can carry out the maintenance work of the maintenance work time "6 hours" is "21:00 to 3:00 the next day" as shown in FIG. .. Here, since "June 21" is a schedule earlier than the recommended maintenance date, it will be an urgent arrangement, but the search function 152 will search as a maintenance candidate date and time. That is, the search function 152 sets "21:00 to 3:00 the next day" of "June 21" as the maintenance candidate date and time.

For example, as shown in FIG. 6, on "June 26", "worker A" can carry out maintenance work from 18:00 to 1:00 the next day. Further, as shown in FIG. 8, on "June 26", the medical device 200 is reserved from 18:00 to 20:00 as the reservation status of the medical device 200. In this case, on "June 26", the time during which "worker A" can perform the maintenance work of the maintenance work time "6 hours" is "19:00 to 1:00 the next day" as shown in FIG. However, from 19:00 to 20:00, there is one reservation for the medical device 200. Here, when the search function 152 has only one reservation for the medical device 200 at the date and time when the maintenance work can be performed, the search function 152 searches for that date and time as the maintenance candidate date and time. That is, the search function 152 sets "19:00 to 1:00 the next day" of "June 26" as the maintenance candidate date and time.

For example, as shown in FIG. 6, on "June 25", "worker B" can carry out maintenance work from 18:00 to 24:00. Further, as shown in FIG. 8, on "June 25", the medical device 200 is reserved from 18:00 to 20:00 as the reservation status of the medical device 200. In this case, on "June 25", the time during which "worker B" can carry out the maintenance work for the maintenance work time "6 hours" is "18:00 to 24:00", but at 18:00 to 20:00. , There are two reservations for the medical device 200. Here, the search function 152 lowers the priority of the date and time when two or more reservations for the medical device 200 are made at the date and time when the maintenance work can be performed. That is, if there is no work time of one reservation or less by the estimated failure time, the candidate is preferentially selected from the date and time when the number of reservations is small, not "no candidate date". For example, if there is no time for a worker to perform maintenance work with a maintenance work time of "6 hours" by the estimated failure time "June 30 (13 days later)", maintenance is prioritized from the date and time when the number of reservations is small. Let it be a candidate date and time.

Next, the process executed by the calculation function 153 will be described. As described above, the calculation function 153 calculates the maintenance price of each of the plurality of maintenance candidate dates and times based on the cost of arranging the replacement part of the failure sign component and the cost of the maintenance work.

FIG. 10 is a diagram showing the relationship between the failure risk and the maintenance cost of the failure sign component “X-ray tube“ XXX ”” in the present embodiment. For example, the maintenance cost of the failure sign component "X-ray tube" XXX "" includes a cost related to arranging a substitute part for the failure sign component "X-ray tube" XXX "" and a cost related to maintenance work. Based on the maintenance cost, the calculation function 153 has a plurality of maintenance candidate dates and times "June 24, 20:00 to 2:00 the next day", "June 21, 21:00 to 3:00 the next day", and "June 26, 19:00". Calculate each maintenance price of "1 o'clock the next day". Here, the part cost "X1" of the alternative part "X-ray tube" XXX "" searched by the search function 152, the transportation cost "Y1" when the delivery date is "6 days", and the delivery date "3 days". In this case, "Y2" corresponds to the cost of arranging a substitute part for the failure sign component "X-ray tube" XXX "". Further, the labor cost “Z1” of the worker required for the maintenance work of the failure sign component “X-ray tube“ XXX ”” searched by the search function 152 corresponds to the cost related to the maintenance work. For example, the calculation function 153 sets the maintenance candidate date and time for "June 24, 20:00 to 2:00 the next day", "June 21, 21:00 to 3:00 the next day", and "June 26, 19:00 to 1:00 the next day". Therefore, it is assumed that the maintenance prices "500,000 yen", "600,000 yen", and "800,000 yen" are calculated, respectively.

As shown in FIG. 10, the failure risk of the failure sign component "X-ray tube" XXX "" is estimated from "June 17", which is the date when the failure sign is estimated, to "June 30 (13 days later)". , And it gets higher. Here, the maintenance price is determined by the failure risk and the maintenance cost. In consideration of the accuracy of estimating the failure sign, the deadline for accepting reservations for maintenance work is set to "June 28", which is two days before the estimated failure time "June 30 (13 days later)". The maintenance price after "June 28" shall be the maximum value. In addition, the recommended maintenance date is "June 24", which is a schedule that does not make an emergency arrangement and is the shortest schedule that allows maintenance work to be carried out by the estimated failure time "June 30 (13 days later)". Therefore, the maintenance price for "June 24" will be the minimum value in consideration of failure risk and maintenance cost.

For example, on the maintenance candidate date and time "June 21st 21:00 to 3:00 the next day", the maintenance work of the failure sign component "X-ray tube" XXX "" is started from the maintenance candidate date and time "June 24th 20:00 to 2:00 the next day". Can also be done before. That is, it is possible to carry out maintenance work while the risk of failure is low. However, if the date and time are before the maintenance candidate date and time "20:00 on June 24 to 2:00 on the next day", urgent arrangements will be required, so maintenance costs such as transportation costs and labor costs will increase. As a result, the maintenance price "800,000 yen" for the maintenance candidate date and time "June 21st 21:00 to 3:00 the next day" is the maintenance price "500,000 yen" for the maintenance candidate date and time "June 24th 20:00 to 2:00 the next day". It will be higher than.

Here, the maintenance candidate date and time "June 26, 19:00 to 1:00 the next day" means that the maintenance cost of the failure sign component "X-ray tube" XXX "" is the maintenance candidate date and time, "June 24, 20:00 to 2:00 the next day." It is the same as the case of. That is, even if the maintenance candidate date and time is later than the maintenance candidate date and time "June 24, 20:00 to 2:00 the next day", the maintenance work may be carried out by "June 30". However, the risk of failure increases on a schedule after the maintenance candidate date and time "20:00 on June 24 to 2:00 on the next day". As a result, the maintenance price "600,000 yen" for the maintenance candidate date and time "June 26, 19:00 to 1:00 the next day" is the maintenance price "500,000 yen" for the maintenance candidate date and time "June 24, 20:00 to 2:00 the next day". It will be higher than.

Further, the calculation function 153 calculates the opportunity loss that occurs when the reservation of the medical device 200 is canceled when the reservation of the medical device 200 is made at at least one maintenance candidate date and time among the plurality of maintenance candidate dates and times. For example, on the maintenance candidate date and time "19:00 on June 26 to 1:00 on the next day", only one reservation for the medical device 200 is entered. In this case, the calculation function 153 calculates "100,000 yen" as the opportunity loss that occurs when one reservation of the medical device 200 is canceled.

Further, the calculation function 153 calculates the maintenance price and the opportunity loss when the failure sign component "X-ray tube" XXX "" fails. For example, the calculation function 153 calculates "1.5 million yen" as the maximum value of the maintenance price when the failure sign component "X-ray tube" XXX "" fails. For example, the calculation function 153 has an opportunity loss of "800,000 yen" as an opportunity loss that occurs when a maximum of eight reservations for the medical device 200 are canceled from daytime to nighttime when the failure sign component "X-ray tube" XXX "" fails. Is calculated.

Next, the processing executed by the output processing function 154 will be described. As described above, the output processing function 154 is a screen showing a failure sign component, an estimated failure time, a plurality of maintenance candidate dates and times, and a maintenance price, and one maintenance candidate date and time is selected from the plurality of maintenance candidate dates and times. Present the screen to accept as. Specifically, the output processing function 154 causes the screen 10 shown in FIG. 11 to be displayed on the display 120.

FIG. 11 is a diagram showing an example of a display screen according to the present embodiment. For example, the screen 10 includes a failure sign component display column 11, a maintenance work time display column 12, and a maintenance candidate date / time display column 20.

For example, the information estimated by the estimation function 151 is displayed in the failure sign component display column 11. Specifically, in the failure sign component display column 11, the failure sign component "X-ray tube" XXX "estimated by the estimation function 151 and the abnormality information when the estimation function 151 monitors the failure sign component are displayed. "Filament resistance value decrease" is displayed. Further, in the failure sign component display column 11, the estimated failure time "June 30 (13 days later)" of the failure sign component estimated by the estimation function 151 and the failure probability "90" of the failure sign component estimated by the estimation function 151 are displayed. % ”Is displayed.

For example, in the maintenance work time display field 12, the maintenance work time "6 hours" searched by the search function 152 is displayed.

For example, in the maintenance candidate date / time display field 20, the reception buttons 21 to 23, the information searched by the search function 152, and the information calculated by the calculation function 153 are displayed. The reception buttons 21 to 23 are buttons for accepting one maintenance candidate date and time as a maintenance date and time from a plurality of maintenance candidate dates and times. For example, the output processing function 154 presents a plurality of maintenance candidate dates and times on the screen 10 in ascending order of maintenance price.

Specifically, in the maintenance candidate date / time display field 20, the maintenance candidate date / time “June 24, 20:00 to 2:00 the next day” searched by the search function 152 in association with the reception button 21 “1” is calculated. The maintenance price "500,000 yen" of the maintenance candidate date and time calculated by 153, the device reservation "0 cases" which is the reservation status of the medical device 200 of the maintenance candidate date and time searched by the search function 152, and the maintenance candidate date and time Opportunity loss "0 yen" is displayed.

Further, in the maintenance candidate date / time display field 20, the calculation function 153 calculates the maintenance candidate date / time "June 26, 19:00 to 1:00 the next day" searched by the search function 152 in association with the reception button 22 "2". The maintenance price "600,000 yen" of the maintenance candidate date and time, the device reservation "1 case" which is the reservation status of the medical device 200 of the maintenance candidate date and time searched by the search function 152, and the maintenance calculated by the calculation function 153. Opportunity loss "100,000 yen" on the candidate date and time is displayed.

Further, in the maintenance candidate date / time display field 20, the calculation function 153 calculates the maintenance candidate date / time "June 21, 21:00 to 3:00 the next day" searched by the search function 152 in association with the reception button 23 "3". The maintenance price "800,000 yen" for the maintenance candidate date and time, the device reservation "0 cases" which is the reservation status of the medical device 200 for the maintenance candidate date and time searched by the search function 152, and the opportunity loss "0" for the maintenance candidate date and time. "0 yen" is displayed.

Further, in the maintenance candidate date / time display column 20, the maintenance price "1.5 million yen", the device reservation "8 cases", and the opportunity loss "" at the time of failure of the failure sign component "X-ray tube" XXX "" calculated by the calculation function 153 are displayed. 800,000 yen "is displayed.

For example, when the user operates the reception button 21 "1" in the maintenance candidate date and time display field 20, the output processing function 154 sets the maintenance candidate date and time "June 24, 20:00 to 2:00 the next day" on the screen 10. Accept as. That is, the maintenance date and time "from 20:00 on June 24 to 2:00 on the next day" is fixed.

When the maintenance date and time "20:00 on June 24 to 2:00 the next day" is confirmed, the output processing function 154 reserves the maintenance work on the maintenance date and time. Specifically, the output processing function 154 has an inventory status (storage location "warehouse" AAA "", inventory "1 piece") and a delivery date "6" of the alternative part "X-ray tube" XXX "" searched by the search function 152. To have the management company that manages the inventory of parts transport the alternative parts "X-ray tube" XXX "" from the storage location "warehouse" AAA "" to the destination "hospital A" based on the "day". Make arrangements for. Further, the output processing function 154 performs "work" for the management company that manages the workers based on the schedules of "worker A", "worker B", and "worker C" searched by the search function 152. Employee A makes a request to have the maintenance work of the failure sign component "X-ray tube" XXX "" performed at "Hospital A" on the maintenance date and time "20:00 on June 24 to 2:00 the next day".

Further, when the maintenance date and time "20:00 on June 24 to 2:00 on the next day" is confirmed, the output processing function 154 makes a reservation for the medical device 200 on the maintenance date and time. Specifically, as shown in FIG. 12, the output processing function 154 reserves the medical device 200 in the examination reservation DB 146 from 20:00 on June 24 to 2:00 the next day as the reservation date and time of the medical device 200. In this case, the output processing function 154 performs a process of prohibiting the reservation of the medical device 200 on the maintenance date and time for the terminal 300 and the server 400, which are devices that manage the reservation of the medical device 200. For example, when the user performs an operation of reserving the medical device 200 on the date and time from 20:00 to 21:00 on June 24 using the terminal 300, the output processing function 154 will make a reservation for the terminal 300. It is shown that the date and time to be set is the maintenance date and time. That is, the output processing function 154 notifies the user by the terminal 300 that the medical device 200 cannot be reserved at the date and time when the reservation is to be made.

FIG. 13 is a diagram showing an example of display timing in the present embodiment. For example, the output processing function 154 determines the timing at which the screen 10 is displayed on the display 120 when the estimation function 151 determines that a component in the medical device 200 has a sign of failure. For example, if there is too much time grace in the number of days t12 from the failure sign estimation date t1 in which the failure sign estimation function 151 estimates the failure sign component to the estimated failure time t2, the output processing function 154 causes the screen 10 to be displayed on the display 120. However, the risk of failure is still low, and users are less conscious of performing maintenance work. On the other hand, if there is too little time grace for the number of days t12, for example, if the output processing function 154 displays the screen 10 on the display 120 near the estimated failure time, it is economical from the relationship between the failure risk and the maintenance cost. Absent. Therefore, the output processing function 154 causes the screen 10 to be displayed on the display 120 when the number of days t12 is within a predetermined number of days. For example, when the predetermined number of days is set to one month and the number of days t12 is within one month, the output processing function 154 causes the screen 10 to be displayed on the display 120. In the present embodiment, the predetermined number of days is set to one month, but the number of days is not limited to this and can be set arbitrarily.

FIG. 14 is a flowchart showing a processing procedure by the information processing apparatus 100 according to the present embodiment.

The estimation function 151 monitors the state of a plurality of parts constituting the medical device 200 and determines whether or not there is a sign of failure (step S101). When the estimation function 151 determines that there is no sign of failure (step S101; No), the determination process of step S101 is performed again.

When the estimation function 151 determines that there is a failure sign (step S101; Yes), the failure sign component estimation process is performed (step S102). In step S102, the estimation function 151 estimates a failure sign component representing a failure sign based on the states of a plurality of components constituting the medical device 200. Further, based on the state of the failure-predicting component and the usage status of the medical device 200, the estimated failure time, which is the failure time of the failure-predicting component, and the failure probability of the failure-predicting component are estimated.

Next, the parts inventory search process is performed (step S103). In step S103, the search function 152 refers to the parts inventory DB 142 and searches for the inventory status and the parts cost of the substitute parts that are the substitutes for the failure sign parts. In addition, the search function 152 searches for the delivery date and transportation cost of the substitute parts with reference to the parts procurement DB 143.

Next, the maintenance work search process is performed (step S104). In step S104, the search function 152 refers to the maintenance work DB 144 and searches for the maintenance work time and labor cost required for the maintenance work of the failure sign component. In addition, the search function 152 refers to the worker DB 145 and searches for a schedule on which the worker can perform maintenance work at night as the worker's schedule.

Next, the maintenance recommended date search process is performed (step S105). In step S105, the search function 152 is a schedule that does not make an emergency arrangement and is estimated based on the time related to the maintenance work of the failure sign part (inventory status and delivery date of the substitute part, maintenance work time, worker's schedule). Search for the shortest schedule for maintenance work that can be performed by the time of failure as the recommended maintenance date.

Next, the reservation status search process is performed (step S106). In step S106, the search function 152 refers to the examination reservation DB 146 and searches for the reservation status of the medical device 200 up to the estimated failure time.

Next, the maintenance candidate date / time search process is performed (step S107). In step S107, the search function 152 searches for a plurality of dates and times during which maintenance work can be performed by the estimated failure time as maintenance candidate dates and times based on the reservation status of the medical device 200 and the time related to the maintenance work of the failure sign component. To do.

Next, the maintenance price calculation process is performed (step S108). In step S108, the calculation function 153 uses the cost related to the arrangement of the replacement part of the failure sign part (part cost of the substitute part, the transportation cost) and the cost related to the maintenance work (the labor cost of the worker required for the maintenance work of the failure sign part). Based on the above, the maintenance price of each of the plurality of maintenance candidate dates and times is calculated. Further, the calculation function 153 calculates the opportunity loss that occurs when the reservation of the medical device 200 is canceled when the reservation of the medical device 200 is made at at least one maintenance candidate date and time among the plurality of maintenance candidate dates and times.

Next, the output processing function 154 determines whether or not there is a grace in the number of days from the date when the failure sign component is estimated to the estimated failure time. That is, it is determined whether or not the number of days is within a predetermined number of days (step S109). If there is a grace period in the number of days and the number of days is not within the predetermined number of days (step S109; No), the determination process of step S101 is performed again. At this time, the output processing function 154 may notify the service center or the like that the failure sign component has been estimated. Examples of the service center include a management company that manages the inventory of parts and a management company that manages workers. For example, the output processing function 154 notifies the management company that manages the inventory of parts in advance that the failure sign parts have been estimated, so that the work of transporting the substitute parts may occur in the future. Can inform you that there is. For example, the output processing function 154 notifies the management company that manages the worker in advance that the failure sign component has been estimated, so that the worker can use the failure sign component by the estimated failure time in the future. It is possible to inform that maintenance work may be carried out.

If there is no grace in the number of days and the number of days is within a predetermined number of days (step S109; Yes), the presentation process is performed (step S110). In step S110, the output processing function 154 represents a failure sign component, an estimated failure time, a plurality of maintenance candidate dates and times, a maintenance price, and an opportunity loss, and one maintenance from a plurality of maintenance candidate dates and times is performed by the reception button. A screen 10 for accepting a candidate date and time as a maintenance date and time is presented.

The output processing function 154 determines whether or not the maintenance date and time has been accepted by the acceptance button (step S111). When the output processing function 154 does not accept the maintenance date and time by the accept button (step S111; No), for example, when the user terminates the display of the screen 10 without operating the accept button, the determination process of step S101 is performed again. ..

When the maintenance date and time is received by the reception button (step S111; Yes), the output processing function 154 performs reservation processing (step S112). In step S112, the output processing function 154 determines the maintenance date and time on the screen 10 and reserves the maintenance work at the maintenance date and time. Specifically, the output processing function 154 arranges for the management company that manages the inventory of parts to transport the substitute parts from the storage location to the transportation destination. Further, the output processing function 154 requests the management company that manages the worker to perform the maintenance work of the failure sign component on the maintenance date and time. Further, the output processing function 154 makes a reservation for the medical device 200 at the maintenance date and time. In this case, the output processing function 154 performs a process of prohibiting the terminal 300 from making a reservation for the medical device 200 on the maintenance date and time.

As described above, in the information processing device 100 according to the present embodiment, the estimation function 151 includes a failure sign component representing a failure sign and the failure sign component based on the states of a plurality of components constituting the medical device 200. Estimated failure time Estimate the failure time. The search function 152 searches for a plurality of dates and times during which maintenance work can be performed by the estimated failure time as maintenance candidate dates and times, based on the reservation status of the medical device 200 and the time related to the maintenance work of the failure sign component. The calculation function 153 calculates the maintenance price of each of the plurality of maintenance candidate dates and times based on the cost of arranging the replacement part of the failure sign component and the cost of the maintenance work. The output processing function 154 represents a failure sign component, an estimated failure time, a plurality of maintenance candidate dates and times, and a maintenance price, and presents a screen 10 that accepts one maintenance candidate date and time from among the plurality of maintenance candidate dates and times as a maintenance date and time. As described above, in the information processing apparatus 100 according to the present embodiment, when the failure sign component and the estimated failure time are estimated, a plurality of maintenance candidate dates and maintenance prices and maintenance prices capable of performing maintenance work by the estimated failure time are presented. Then, when the user selects one maintenance candidate date and time as the maintenance candidate date and time from the plurality of maintenance candidate dates and times, the user can execute the maintenance request of the medical device 200 at an appropriate timing.

Further, in the information processing device 100 according to the present embodiment, the calculation function 153 makes a reservation for the medical device 200 when the medical device 200 is reserved at at least one maintenance candidate date and time among the plurality of maintenance candidate dates and times. The opportunity loss that occurs when the cancellation occurs is calculated, and the output processing function 154 presents the opportunity loss on the screen 10. As described above, in the information processing apparatus 100 according to the present embodiment, by further presenting the opportunity loss, the user can consider one maintenance candidate from a plurality of maintenance candidate dates and times while considering the maintenance price and the opportunity loss. The date and time can be selected as the maintenance date and time.

Further, in the information processing apparatus 100 according to the present embodiment, the output processing function 154 presents a plurality of maintenance candidate dates and times in ascending order of maintenance price. For example, when the user selects the earliest maintenance candidate date and time as the maintenance candidate date and time among a plurality of maintenance candidate dates and times, the user can perform the maintenance work while the failure risk is low. However, if the earliest maintenance candidate date and time is selected as the maintenance date and time, urgent arrangements will be required, and maintenance costs such as transportation costs and labor costs will increase. As described above, in the information processing apparatus 100 according to the present embodiment, by presenting a plurality of maintenance candidate dates and times in ascending order of maintenance price, the user can select from a plurality of maintenance candidate dates and times while considering the maintenance price and the like. One maintenance candidate date and time can be selected as the maintenance date and time.

Further, in the information processing device 100 according to the present embodiment, when the maintenance date and time is fixed, the output processing function 154 performs a process of prohibiting the reservation of the medical device 200 on the maintenance date and time. At this time, when the date and time when the user intends to reserve the medical device 200 is the maintenance date and time, the output processing function 154 notifies the user that the date and time when the user intends to reserve the medical device 200 is the maintenance date and time. As described above, in the information processing device 100 according to the present embodiment, when the maintenance date and time is fixed, the user mistakenly reserves the medical device 200 on the maintenance date and time by prohibiting the reservation of the medical device 200 on the maintenance date and time. Can be prevented.

Further, in the information processing apparatus 100 according to the present embodiment, the output processing function 154 presents the screen 10 when the number of days from the date when the failure sign component is estimated to the estimated failure time is within a predetermined number of days. If there is too much time to spare for the above number of days, even if the output processing function 154 presents the screen 10, the risk of failure is still low, and the user is less conscious of performing maintenance work. On the other hand, if there is too little time grace for the above number of days, for example, if the output processing function 154 presents the screen 10 near the estimated failure time, it is not economical due to the relationship between the failure risk and the maintenance cost. Therefore, the output processing function 154 presents the screen 10 when the number of days is within a predetermined number of days, so that the user can execute the maintenance request of the medical device 200 at an appropriate timing.

(Other variants)
Although this embodiment has been described, it may be implemented in various different forms other than the above-described embodiment.

In the present embodiment, in step S110, the output processing function 154 causes the screen 10 shown in FIG. 11 to be displayed on the display 120, but the present invention is not limited to this. For example, as a modification of the present embodiment, as shown in FIG. 15, the output processing function 154 displays a screen 30 showing the reservation status of the medical device 200 on the display 120 as reference information to the user together with the screen 10.

For example, when the screen 10 and the screen 30 are displayed on the display 120, the output processing function 154 sets the maintenance candidate date and time display field 20 of the screen 10 in association with the reception button 22 “2” and sets the maintenance candidate date and time “2”. "June 26, 19:00 to 1:00 the next day", the maintenance price "600,000 yen" on the maintenance candidate date and time, the device reservation "1 case" which is the reservation status of the medical device 200 on the maintenance candidate date and time, and the maintenance Opportunity loss "100,000 yen" on the candidate date and time is displayed. At this time, by referring to the reservation status of the medical device 200 displayed on the screen 30, the user has one reservation for the medical device 200 at the maintenance candidate date and time "June 26, 19:00 to 1:00 the next day". You can confirm that.

Further, in the present embodiment, in step S110, the output processing function 154 cancels the reservation of the medical device 200 when the medical device 200 is reserved at at least one maintenance candidate date and time among the plurality of maintenance candidate dates and times. The opportunity loss that occurs when this is done is displayed on the display 120 by the screen 10, but the present invention is not limited to this. For example, as a modification of the present embodiment, when a plurality of medical devices 200 are installed in the hospital, the output processing function 154 presents information for avoiding opportunity loss on the screen 10. Hereinafter, the plurality of medical devices 200 will be referred to as medical devices 200A and 200B. The medical devices 200A and 200B have the same functions.

Specifically, as shown in FIG. 16, when the screen 10 is displayed on the display 120, the output processing function 154 maintains the maintenance candidate date and time display field 20 in association with the reception button 22 “2”. Candidate date and time "19:00 on June 26 to 1:00 the next day", maintenance price "600,000 yen" on the maintenance candidate date and time, and device reservation "1 case" which is the reservation status of the medical device 200 on the maintenance candidate date and time. , The opportunity loss "100,000 yen" of the maintenance candidate date and time, and the reservation search button 24 for searching whether or not the medical device 200 can be changed from the medical device 200A to the medical device 200B are displayed. That is, in the maintenance candidate date / time display field 20, the reservation search button 24 is further displayed in association with the reception button 22 "2".

For example, when the user operates the reservation search button 24 in the maintenance candidate date / time display field 20, the search function 152 refers to the inspection reservation DB 146 and is a medical device up to the estimated failure time "June 30 (13 days later)". Search the reservation status of 200B. Specifically, the search function 152 searches for the reservation status of the medical device 200B having the same function as the medical device 200A.

In this embodiment, as a premise, the maintenance work is performed on a holiday or at night on weekdays. As an example, the worker performs the maintenance work at night on weekdays (for example, from 18:00 to 6:00 the next day). The case of doing so was explained. Further, in the present embodiment, as a premise, it is assumed that one device reservation is made per hour, and a case where the device reservation is made even after 18:00 has been described. However, it is not limited to this. For example, two or more device reservations may be made per hour, and if there are days when there are few reservations for the medical device 200, maintenance work may be performed during the daytime on weekdays. In addition, maintenance work may be carried out only at night.

Further, in the present embodiment, each process is performed in the order of maintenance recommended date search process (step S105), reservation status search process (step S106), maintenance candidate date / time search process (step S107), and maintenance price calculation process (step S108). However, it is not limited to this. For example, as a modification of this embodiment, steps S105 to S108 may be executed by one process.

For example, the search function 152 refers to the examination reservation DB 146 and searches for the reservation status of the medical device 200 up to the estimated failure time. The search function 152 searches for a plurality of dates and times during which maintenance work can be performed by the estimated failure time as maintenance candidate dates and times, based on the reservation status of the medical device 200 and the time related to the maintenance work of the failure sign component. The calculation function 153 calculates the maintenance price of each of the plurality of maintenance candidate dates and times based on the cost of arranging the replacement part of the failure sign component and the cost of the maintenance work. Further, the calculation function 153 calculates the opportunity loss that occurs when the reservation of the medical device 200 is canceled when the reservation of the medical device 200 is made at at least one maintenance candidate date and time among the plurality of maintenance candidate dates and times. Then, the calculation function 153 sets the maintenance candidate date and time with the lowest maintenance price as the maintenance recommended date and time among the plurality of maintenance candidate dates and times.

Further, in the present embodiment, the search function 152 refers to the maintenance work DB 144 and searches for the maintenance work time and labor cost required for the maintenance work of the failure sign component, but the maintenance work is only replacement or repair. Not limited to. For example, as an example of the maintenance work, the work of replacing the failure sign component "X-ray tube" XXX "" with the substitute part "X-ray tube" XXX "" has been mentioned, but other adjustments and the like can be mentioned. Specifically, when the part "top plate" on which the subject is placed is taken as an example of one of the plurality of parts constituting the medical device 200 "X-ray CT device", "top plate" is used as an example. It is assumed that the position of the "top plate" is misaligned. Therefore, for example, when the deviation of the "top plate" exceeds a predetermined threshold value, the "top plate" is estimated as a failure sign component. In this case, as maintenance work, work is performed to adjust the deviation of the failure sign component "top plate".

Further, in the present embodiment, the estimation function 151 estimates the estimated failure time and failure probability based on the state of the failure sign component and the usage status of the medical device 200. Specifically, the estimation function 151 estimates the estimated failure time and failure probability with reference to the failure history DB 141. However, it is not limited to this. For example, the estimation function 151 may estimate the estimated failure time and failure probability by learning using AI (Artificial Intelligence) based on a neural network or machine learning. For example, by learning a combination of data including an estimated failure time and a failure probability by AI or the like, the estimation function 151 can estimate the estimated failure time and the failure probability based on the parts that have failed so far.

Further, the processing circuit 150 may realize the function by utilizing the processor of the external device connected via the network.
