Here, the period required for procurement (procurement period: lead time) varies depending on the type of component. Therefore, it is necessary to secure a procurement budget for procuring parts according to the procurement period. On the other hand, a procurement budget frame for procuring parts is set in advance according to the procurement period.

  The client-side data server 5 stores various types of information held by the client, and provides various types of information to the component support system 1 via the network 2. Here, as information provided from the client-side data server 5 to the parts support system 1, for example, information required for parts procurement and a part procurement quantity that reflects the part procurement policy are calculated. There is a predetermined calculation formula. The client-side data server 5 can only be accessed from the client side, and cannot be accessed from the component manufacturer side.

The component manufacturing side data server 7 can only be accessed from the component manufacturing side, and cannot be accessed from the client side. Information output from the component manufacturing side terminal 8 and another input device (not shown) is input to the component manufacturing side data server 7.

  Again, referring to FIG. 1, the component support system 1 will be described. The component support system 1 includes a component support server 10 and a processing unit 11, and is connected to the client side data server 5, the client side terminal 6, the component manufacturing side data server 7, and the component manufacturing side terminal 8 via the network 2. Has been.

  The component support server 10 acquires information necessary for procurement of components provided from an external device as specification data D related to components, and stores this. That is, the external devices that provide the specification data D are the client-side data server 5 of the client that owns the aircraft and the parts manufacturing-side data server 7 of the manufacturer that manufactures the aircraft parts. In the present embodiment, the specification data D is stored in the component support server 10, but the present invention is not limited to this configuration. The client-side data server 5 may have a function as a component support server. That is, the configuration may be such that the specification data D is stored in the client-side data server 5 and the component support server 10 shown in FIG. 1 is omitted.

  Here, the specification data D will be described. The specification data D is data unique to one part, and a plurality of pieces of data D are prepared according to the type of part. That is, specification data D corresponding to tens of thousands of parts is prepared. The specification data D includes consumption actual product information that is information related to actual consumption of parts, consumption prediction information that is information related to consumption prediction of parts, repair information that is information related to repair of parts, and flight time of aircraft. And at least flight time information, which is information. The specification data D also includes parts inventory information that is information related to parts inventory. That is, the specification data D is information necessary to procure parts, and thus may include information other than the information described above.

  The processing unit 11 includes an integrated circuit such as a CPU (Central Processing Unit) and a memory serving as a work area, and executes various processes by executing various programs using these hardware resources. The processing unit 11 can execute the component support program P as various programs, and the component support program P is stored in a storage area (not shown) provided in the processing unit 11. The component support program P may be stored in a separate storage device, and is not particularly limited. The processing unit 11 executes the component support program P, for example, calculates the procurement amount of the component based on the specification data D acquired from the component support server 10, and includes the calculated procurement amount of the component, etc. A calculation detail list and budget anastomosis data are generated, or image information for displaying a display screen on the display unit 22 of the external client side terminal 6 and the display unit 32 of the component manufacturing side terminal 8 is generated.

  Next, the control operation (component support method) of the component support system 1 will be described with reference to FIG. The control operation shown in FIG. 3 relates to processing for calculating the procurement quantity of parts based on the specification data D.

  The processing unit 11 of the component support system 1 acquires the specification data D stored in the component support server 10 (step S10: specification data acquisition step). Further, the processing unit 11 acquires a calculation formula provided from the client side data server 5 (step S11: calculation formula acquisition step). Subsequently, the processing unit 11 executes an integration simulation based on the acquired specification data D and the calculation formula (step S12).

  Here, when the integration simulation is executed in step S12, the specification data D includes consumption prediction information. Therefore, the processing unit 11 calculates the consumption prediction value of the part from the consumption prediction information, and calculates the calculated consumption prediction. Based on the value, the procurement quantity for each part procurement period is calculated. In addition, the specification data D includes actual consumption information, repair information, flight time information, and inventory information in addition to the consumption prediction information. Therefore, the consumption prediction value is calculated by taking these information into account. Based on the predicted consumption value, the procurement quantity of parts is calculated. That is, step S12 is a procurement quantity calculation process in which the processing unit 11 calculates the procurement quantity of parts by executing an integration simulation. Further, in step S12, based on the procurement quantity calculated for each procurement period of the parts, the parts are arranged so as to be within the procurement budget frame for each procurement period (yearly) shown in FIG. The procurement quantity is calculated.

  Subsequently, the processing unit 11 executes statistical demand prediction (step S13). In step S13, in addition to the component consumption prediction based on the integration simulation in step S12, the component demand prediction using a statistical method (or machine learning) is performed. As a statistical method, for example, Weibull analysis or the like is applied. Note that the statistical demand prediction in step S13 will be described later with reference to FIG.

  Next, the process part 11 acquires the procurement budget frame for every procurement period (every year) shown in FIG. 2 from the components assistance server 10 (step S14). And the process part 11 produces | generates a calculation details list | wrist based on the various information acquired in step S10 to step S14 (step S15). The calculation details list is data including component specification data D, component specification data calculated by integration simulation, and the calculated procurement quantity of components. The calculation details list generated in step S15 is a calculation details list before the payment check process in step S19 described later, and is a calculation details list (# 1) that is an initial value. The generated calculation details list can be displayed as the calculation details list screen 41 shown in FIG. 8 on the display unit 22 of the client side terminal 6 and the display unit 32 of the component manufacturing side terminal 8. The calculation details list screen 41 shown in FIG. 8 will be described later.

  Thereafter, the processing unit 11 generates budget anastomosis data based on various information acquired in steps S10 to S14 (step S16). The budget anastomosis data is data including a procurement budget amount for each part procurement period, a procurement budget frame for each procurement period, and the like. The budget anastomosis data generated in step S16 is also the budget anastomosis data before the examination / payment processing in step S19 described later, and is the budget anastomosis data (# 1) that is the initial value. The generated budget anastomosis data can be displayed on the display unit 22 of the client side terminal 6 and the display unit 32 of the component manufacturing side terminal 8 as a budget anastomosis data screen 61 shown in FIG. The budget anastomosis data screen 61 shown in FIG. 9 will be described later.

  When the calculation details list (# 1) and the budget anastomosis data (# 1) are generated, the client executes an examination process as to whether or not the procurement quantity of parts and the procurement budget are appropriate (step S17). . As a result of the examination process, if it is judged that the parts procurement quantity and the procurement budget amount are not appropriate, the processing unit 11 executes a correction process (step S18). The correction process S17 is not executed if there is no need for correction, that is, if the procurement quantity of parts and the procurement budget are appropriate. If the calculation details list and the budget anastomosis data are appropriate, the parts manufacturer is notified whether the parts can be delivered and whether the parts budget is appropriate. A payment inspection process for inputting an answer obtained from the component manufacturer as a payment inspection result is executed by the client (step S19). In the payment process S19, the payment result data may be transmitted to the client side to perform batch update.

  In step S19, when the parts manufacturer executes the inspection process, the processing unit 11 acquires the results of the examination process and the inspection process, and generates a calculation details list based on the acquired results (step S20). Budget anastomosis data is generated (step S21). The calculation details list generated in step S20 is the calculation details list after the payment processing in step S19, and is the calculation details list (# 2) after the payment. The budget anastomosis data generated in step S21 is the budget anastomosis data after the payment process in step S19, and is budget anastomosis data (# 2) after the payment.

  When the calculation details list (# 2) and the budget anastomosis data (# 2) are generated, the client again executes an examination process as to whether or not the procurement quantity of parts and the procurement budget are appropriate (step) S22). As a result of the examination process, if it is judged that the procurement quantity of parts and the procurement budget amount are not appropriate, the processing unit 11 executes the correction process again (step S23). The correction process S23 is not executed if there is no need for correction, that is, if the procurement quantity and procurement budget amount of parts are appropriate. If it is determined that the calculation details list and the budget anastomosis data are appropriate, the processing unit 11 determines the procurement quantity of the component, and accordingly determines the procurement budget amount of the component (step S24). And the process part 11 produces | generates the required procurement list | wrist for procuring components based on the procurement quantity and procurement budget amount of the determined components (step S25).

  In addition, the order of the steps shown in FIG. 3 is not particularly limited, and may be changed as appropriate depending on the part procurement mode.

  Next, the correction process in steps S18 and S23 will be described with reference to FIG. In the correction process, if the client determines that the procurement quantity and the procurement budget amount of the parts are not appropriate based on the generated calculation details list (# 1, # 2) and budget anastomosis data (# 1, # 2), the parts The consumption forecast information of the aircraft is corrected and the flight time information of the aircraft is corrected. When executing the correction process, the processing unit 11 determines whether or not the consumption prediction information or the flight time information is corrected (step S31). When it is determined that the consumption prediction information or the flight time information is corrected (step S31: Yes), the processing unit 11 determines whether the consumption prediction information is corrected (step S32). When the processing unit 11 determines that the consumption prediction information is corrected (step S32: Yes), the processing unit 11 re-executes the integration simulation based on the corrected consumption prediction information (step S33). Note that the integration simulation in step S33 is the same as that in step S12, and a description thereof will be omitted. Subsequently, the processing unit 11 determines whether or not the flight time information is corrected (step S34). When determining that the flight time information is corrected (step S34: Yes), the processing unit 11 re-executes the integration simulation based on the corrected flight time information (step S35). Note that the integration simulation in step S35 is the same as step S12, and thus the description thereof is omitted.

  In step S31, when the processing unit 11 determines that the consumption prediction information or the flight time information is not corrected (step S31: No), the process proceeds to step S36. Moreover, in step S32, if the process part 11 determines with there being no correction of consumption prediction information (step S32: No), it will progress to step S34. In step S34, when the processing unit 11 determines that the flight time information is not corrected (step S34: No), the process proceeds to step S36.

  And the process part 11 acquires the procurement budget frame for every procurement period (every year) shown in FIG. 2 from the components assistance server 10 (step S36). Step S36 is the same as step S14. And the process part 11 produces | generates the calculation details list based on a correction process (step S37). Step S37 corresponds to step S15 or step S20. Moreover, the process part 11 produces | generates the budget anastomosis data based on a correction process (step S38). Step S38 corresponds to step S16 or step S21.

  The processing unit 11 displays the generated calculation details list as the calculation details list screen 41 shown in FIG. 8, and the generated budget anastomosis data as the budget anastomosis data screen 61 shown in FIG. 22 and display on the display unit 32 of the component manufacturing side terminal 8 (step S39). The processing unit 11 determines whether or not there is an input indicating that the procurement quantity of parts and the procurement budget amount are appropriate based on the generated calculation details list and budget anastomosis data (step S40). The processing unit 11 ends the correction process when there is an input indicating that the procurement quantity of parts and the procurement budget are appropriate. On the other hand, if there is an input that the procurement quantity and the procurement budget of the parts are not appropriate, the processing unit 11 proceeds to step S31 again until the procurement quantity and the procurement budget of the parts are appropriate. Repeat the above steps.

  Next, the statistical demand prediction process in step S13 will be described with reference to FIG. The processing unit 11 acquires maintenance record data provided from an external device such as the client side data server 5 or the parts manufacturing side data server 7 (step S51), flight record data (step S52), and flight plan data (steps). S53), periodic repair plan data (step S54) is acquired. The order of obtaining the data is not particularly limited.

  When the processing unit 11 acquires the above data, the processing unit 11 uses the acquired data to execute a demand prediction of a part by a statistical method (or machine learning) such as a Weibull analysis, and calculates a demand prediction value (Step S11). S55). The processing unit 11 determines whether or not the calculated demand prediction value is an appropriate value (step S56), and determines that the demand prediction value is an appropriate value (step S56: Yes), determines the demand prediction value. (Step S57), the process ends. On the other hand, when the processing unit 11 determines that the calculated demand forecast value is not an appropriate value (step S56: No), the above-described data is corrected, and a statistical method such as Weibull analysis is performed using the corrected data. The demand forecast of the parts using is re-executed and the demand forecast value is calculated (step S58). Thereafter, the processing unit 11 again proceeds to step S56, and repeatedly executes step S58 until the demand predicted value becomes an appropriate value.

  Next, with reference to FIG. 6 and FIG. 7, the demand prediction guide information calculated by the processing unit 11 when the calculation details list and the budget anastomosis data are generated will be described. The demand prediction guide information is information generated based on the consumption record information and the consumption prediction information included in the specification data D, and is displayed on the calculation details list screen 41 and the budget anastomosis data screen 61 described later.

  In FIG. 6, the horizontal axis represents the procurement period (year), and the vertical axis represents the procurement quantity of parts. In addition, based on the calculation year, the procurement quantity of parts for the past five years, that is, from “X-1 year” to “X-5 year” is the actual number of parts consumed annually. That is, the procurement quantity of parts from “FY X” to “X + F4” is the predicted annual consumption of parts. The annual consumption actual number is calculated based on the consumption actual information, and the annual consumption predicted number is calculated based on the consumption predicted information.

  As illustrated in FIG. 7, when calculating the demand prediction guide information, the processing unit 11 calculates the average value of the predicted annual consumption of parts for five years in the future (step S61). Thereafter, the processing unit 11 calculates an average value of the actual number of actual consumptions of parts for the past five years (step S62). And the process part 11 produces | generates the value which divided the average value of the annual consumption prediction number calculated by step S61 by the average value of the annual consumption actual number calculated by step S62 as demand prediction standard information (step S63). . The processing unit 11 displays the generated demand prediction guide information on the calculation details list screen 41 shown in FIG. 8 and the budget anastomosis data screen 61 shown in FIG. 9 (step S64).

  Next, the calculation details list screen 41 will be described with reference to FIG.
