In this embodiment, the process procedure is explained separately for a new registration process (
The customer that places a new order for manufacturing printed boards transmits new order data including the part table in a tabular format to the person-in-charge terminal 30. The part table in this new order data includes data on the part name, the manufacturer name, the type name, the number of parts, the remarks, the comments on part, and the address information for each part. The person in charge that accepts the manufacturing order inputs order information using the person-in-charge terminal 30 based on this new order data. As shown in
As shown in
The management computer 21 performs a part-table check process (at step S1-2). Specifically, the person in charge inputs a part-table check process execution request for the registered part table to the management computer 21 using the person-in-charge terminal 30. The management computer 21 executes a part table-validity check process shown in
As shown in
The management computer 21 checks whether data on the part name, the type name, the manufacturer name, and the like is completely set for this first order part data (at step S2-3). Specifically, the management computer 21 determines whether the data on the part name, the type name, and the manufacturer name is set in the order part data. If the data is not completely set (“NO” at step S2-3), the management computer 21 records the part in the storage unit within the management computer 21 as a check target part (at step S2-4) and moves the process to step S2-5. If the data is completely set (“YES” at step S2-3), the management computer 21 moves the process directly to step S2-5.
The management computer 21 checks whether customer comments reflect in this order part data (at step S2-5). Specifically, the management computer 21 compares data on the customer comments included in the order data 240 with the data recorded in the order part data. If the customer comments do not reflect in the order part data (“NO” at step S2-5), the management computer 21 records the part in the storage unit within the management computer 21 as a check target part (at step S2-6) and moves the process to step S2-7. If the customer comments reflect in the order part data (“YES” at step S2-5), the management computer 21 moves the process directly to step S2-7.
The management computer 21 checks whether there is no duplicate address for this order part data (at step S2-7). Specifically, the management computer 21 determines whether the address information recorded in the address information data area of this part data is redundantly recorded in the part table. If the duplicate address is present (“NO” at step S2-7), the management computer 21 records the part in the storage unit within the management computer 21 as a check target part (at step S2-8) and moves the process to step S2-9. If there is no duplicate address (“YES” at step S2-7), the management computer 21 moves the process directly to step S2-9.
If order part data that is not subjected to the part table-validity check process yet remains in the part table data (“NO” at step S2-9), the management computer 21 returns the process to step S2-1 and performs the part table-validity check process on next order part data included in the part table data. The management computer 21 repeats the part table-validity check process from steps S2-1 to S2-9 until all the order part data is subjected to the process.
If the process on all the order part data is finished (“YES” at step S2-9), the management computer 21 displays the recorded check target parts on the person-in-charge terminal 30 (at step S2-10).
The person in charge corrects the part table based on information on the check target parts displayed on this person-in-charge terminal 30. Upon finishing correction, the person in charge inputs a part-table check process execution request again. The management computer 21 re-executes the part table-validity check process shown in
Thereafter, the management computer 21 performs a part-information search process (at step S1-3). Specifically, when the part-table check process is finished, the person in charge inputs a part information search request to the management computer 21 using the person-in-charge terminal 30. The management computer 21 executes the part-information search process shown in
Specifically, as shown in
If the part name of this customer designated part is recorded in the common-part-data storage unit 22 (“YES” at step S3-2), the management computer 21 records the knowledge data 230 in which the customer designated part name and the common part name are set (at step S3-3). Specifically, the management computer 21 records the part name in the order part data as the customer designated part name and the part name in the common part data 220 as the common part name.
The management computer 21 acquires data on the possible alternative part (at step S3-4). Specifically, the management computer 21 searches the common-part-data storage unit 22 based on the type name, the characteristic values, and the price of the common part data 22 searched based on the part name in the order part data. In this embodiment, the management computer 21 searches the common-part-data storage unit 22 for the possible alternative part of the same part name, equal or greater characteristic values, and an equal or a lower price. In addition, the management computer 21 extracts the possible alternative part having an approval status equal to or higher than that of the common part data 220 corresponding to the order part data.
If the possible alternative part is present (“YES” at step S3-5), the management computer 21 checks whether the part extracted as the possible alternative part is approved (at step S3-6). Specifically, if the approval status of the extracted possible alternative part is “approved” or “recommended”, this indicates that the possible alternative part is approved.
If the possible alternative part is approved (“YES” at step S3-6), the management computer 21 determines that the part of this order part data is replaceable (at step S3-7). In this case, the management computer 21 records alternative-part consideration data, in which the customer designated part information, the proposed alternative part information, and “approval” as the replacement approval or disapproval are set, while associating the alternative-part consideration data with the customer name and the part table identification information included in the replacement consideration data 241. If the part name (customer designated part name), the manufacturer name, and the type name in the order part data as well as the corresponding common part data 220 are present, the customer designated part information includes the part name (common part type name) in this common part data 220. In addition, the proposed alternative part information includes the part number, the part name (alternative part name), the manufacturer name, the approval status, the characteristic values (1) to (5), the price, and the other detailed information in the common part data 220 on the common part.
If no possible alternative part is present (“NO” at step S3-5), the management computer 21 determines that the part of this order part data is irreplaceable (at step S3-10). In this case, the management computer 21 records the alternative-part consideration data, in which the customer designated part information and “disapproval” as the replacement approval or disapproval are set, while associating the alternative-part consideration data with the customer name and the part table identification information in the replacement consideration data 241. If the part of the order part data is recorded in the common-part-data storage unit 22 and the approval status of the part is “recommended”, this part is used and not replaced by the alternative part. In this case, similarly to the above, the management computer 21 determines that no possible alternative part is present and that this part is irreplaceable. In this case, the management computer 21 records the alternative-part consideration data, in which the customer designated part information and “replacement unnecessary” as the replacement approval or disapproval are set, while associating the alternative-part consideration data with the customer name and the part table identification information in the replacement consideration data 241.
If the part of the common part data 220 extracted as the possible alternative part is not approved (“NO” at step S3-6), the management computer 21 determines that the part of this order part data is irreplaceable (at step S3-10). The management computer 21 records the replacement consideration data, in which the customer designated part information, the proposed alternative part information, and a replacement disapproval flag which means that replacement is “disapproved” are set, while associating the alternative-part consideration data with the customer name and the part table identification information in the replacement consideration data 241.
If the part name in the order part data is not recorded in the common-part-data storage unit 22 (“NO” at step S3-2), the management computer indicates registration of the part data in the common-part-data storage unit 22 (at step S3-8). Specifically, the management computer 21 designates the part name on the display of the person-in-charge terminal 30 to display a part registration indication thereon. The person in charge designates the part name of this part and transmits a part registration request to a parts manager based on this indication. The parts manager acquires information on this part based on the part name designated by the person in charge and registers the part in the common-part-data storage unit 22 using the parts manager terminal 31. The common part data 220 on this part is thereby recorded in the common-part-data storage unit 22.
The management computer 21 checks whether a similar part to the part of this order part data is present (at step S3-9). Specifically, the management computer 21 checks whether the common part data 220 of the same type, similar characteristic values, and a similar price to the part of the order part data is present based on the designated type name, characteristic values, and price. If such common part data 220 is recorded, this indicates that the similar part is present. If the similar part is present (“YES” at step S3-9), the management computer 21 moves the process to step S3-4. At step S3-4, the management computer 21 acquires the data on the possible alternative part based on the designated type name, characteristic values, and price for the part of this order part data.
If no similar part is present (“NO” at step S3-9), the management computer 21 determines that the part of this order part data is irreplaceable (at step S3-10). In this case, the management computer 21 records the replacement disapproval flag while associating the flag with the order part data.
If the part of the order part data is the previously used part (“YES” at step S3-1), the management computer 21 checks whether this part is a previously replaceable part (at step S3-11). Specifically, the management computer 21 searches data on previous approval or disapproval for the searched knowledge data 230 in the knowledge-data storage unit 23 based on the customer name and the part name in the order part data recorded in the order data 240. If “approval” is recorded as the past replacement approval or disapproval, this indicates that the part is the previously replaceable part. If the part is the previously replaceable part (“YES” at step S3-11), the management computer 21 moves the process to step S3-4. If the part is not the previously replaceable part (“NO” at step S3-11), the management computer 21 determines that the part is irreplaceable (at step S3-10). The management computer 21 records the replacement disapproval flag while associating the flag with the order part data.
If order part data which is not subjected to the search process yet remains in the part table data (“NO” at step S3-12), the management computer 21 returns the process to step S3-1 and performs the process on the next order part data included in the part table data. The management computer 21 repeats the process from steps S3-1 to S3-12 until all the order part data is subjected to the process. If this process on all the order part data in the part table data is finished (“YES” at step S3-12), the management computer 21 finishes the part-information search process.
The management computer 21 then executes an alternative-part consideration process (at step S1-4). The management computer 21 displays a replacement consideration screen 70 shown in
As shown in
The person in charge considers whether to make a replacement proposal for this part while referring to the replacement approval or disapproval in the customer side information display area 73 and the approval status in the alternative part search information display area 75. The person in charge inputs whether to make the replacement proposal in an input section of proposal presence or absence in the replacement proposal activity display area 74. Information as to whether the replacement proposal is present is thereby recorded in the replacement-proposal-activity information included in the proposed alternative part data.
The management computer 21 then executes a replacement consideration check process for rechecking a replacement consideration result input by the person in charge.
As shown in
The management computer 21 checks whether the common part is an in-company approved part for the part name in the proposed alternative part information included in the alternative-part consideration data (at step S4-3). Specifically, the management computer 21 checks the approval status for the common part data 220 searched based on the part name in the proposed alternative part information. If the approval status is “approved” or “recommended”, the common part is the in-company approved part. If the part is not the in-company approved part (“NO” at step S4-3), the management computer 21 records the part name, the type name, and “no approval” as the check information in the storage unit of the management computer 21 as the data of a check target part (at step S4-4). The management computer 21 then moves the process to step S4-5. If the part is the in-company approved part (“YES” at step S4-3), the management computer 21 moves the process directly to step S4-5.
The management computer 21 checks whether it is confirmed that the part is replaceable or irreplaceable (at step S4-5). Specifically, if the replacement approval or disapproval in the alternative part consideration data indicates “approval”, the management computer 21 determines that it is confirmed that the part is replaceable or irreplaceable. If it is not confirmed that the part is replaceable or irreplaceable (“NO” at step S4-5), the management computer 21 records the part name, the type name, and “not confirmed that part is replaceable” as the check information in the storage unit of the management computer 21 as the data of a check target part (at step S4-6). The management computer 21 then moves the process to step S4-7. If it is confirmed that the part is replaceable or irreplaceable (“YES” at step S4-5), the management computer 21 moves the process directly to step S4-7.
If alternative-part consideration data that is not subjected to the check process yet remains in the replacement consideration data 41 (“NO” at step S4-7), the management computer 21 returns the process to step S4-1 and performs the process on the next alternative-part consideration data. The management computer 21 repeats the process from steps S4-1 to S4-7 until the process on all the alternative-part consideration data is finished.
If the process on all the alternative-part consideration data is finished (“YES” at step S4-7), a replacement consideration result check screen that includes the part names, the type names, and the check information of the check target parts recorded in the storage unit within the management computer 21 is displayed on the person-in-charge terminal 31 (at step S4-8). The person in charge reconsiders the replacement using the replacement consideration screen 70 while referring to the information displayed on the replacement consideration result check screen, and inputs a replacement proposal. If the replacement consideration is finished, the management computer 21 moves the process to a replacement proposal creation process.
As shown in
If the process is not finished on all the alternative-part consideration data (“NO” at step S5-3), the management computer 21 returns the process to step S5-1 and executes the process on the next alternative-part consideration data. The management computer 21 repeats the process from steps S5-1 to S5-3 until the process on all the alternative-part consideration data is finished (until “YES” at step S5-3).
If the process is finished on all the alternative-part consideration data (“YES” at step S5-3), the management computer 21 completes creating the replacement proposal to be submitted to the customer. The person in charge submits the replacement proposal to the customer (at step S5-4). Specifically, the management computer 21 registers the customer name in the replacement proposal data based on the customer name included in the replacement consideration data 241, and finishes creating the replacement proposal. The person in charge acquires the created replacement proposal (replacement proposal data) from the operational support server 20, attaches this replacement proposal to an electronic mail (hereinafter, “email”), and sends the proposal-attached email to the customer terminal 40.
If receiving this replacement proposal data using the customer terminal 40, the customer displays the replacement proposal based on this replacement proposal data on the customer terminal 40. In addition, the customer considers a content of the replacement proposal and determines whether to approve the replacement.
As shown in
If the replacement is not approved (“NO” at step S6-1), the customer registers the proposed alternative part in the replacement proposal as a disapproved alternative part (at step S6-3). Specifically, the customer records “disapproval” in the replacement approval or disapproval input section for this customer designated part in the replacement proposal data displayed on the customer terminal 40.
If the process is not finished on all proposed alternative parts (“NO” at step S6-4), the customer returns the process to step S6-1 and performs the process on the next proposed alternative part. The customer repeats the process until the process on all the proposed alternative parts is finished (until “YES” at step S6-4).
If the process on all the proposed alternative parts is finished (“YES” at step S6-4), the customer submits the replacement proposal, in which the displacement approval or disapproval is recorded, to the person in charge (at step S6-5). Specifically, the customer sends an email to which the replacement proposal, in which the displacement approval or disapproval is recorded, is attached to person-in-charge terminal 30 using the customer terminal 40.
If the person in charge receives the email to which the replacement proposal, in which the displacement approval or disapproval is recorded, is attached using the person-in-charge terminal 30, the person in charge inputs the replacement proposal data, in which the displacement approval or disapproval is recorded, to the operational support server 20 using the person-in-charge terminal 30. The management computer 21 of the operational support server 20 executes a replacement consideration result registration process using the replacement proposal data, in which the displacement approval or disapproval is recorded.
As shown in
If the proposed alternative part is not the approved alternative part (“NO” at step S7-2), the management computer 21 registers the customer designated part as the part to be used (at step S7-4). Specifically, the management computer 21 records the order part data based on the customer designated part information included in the proposed alternative part data.
The management computer 21 records data on the part to be used in the knowledge-data storage unit 23 (at step S7-5). Specifically, the management computer 21 records the customer name, the customer designated part name, the common part name, and the alternative part name based on the data on the customer name, the customer designated part name, the common part name, and the alternative part name included in the proposed alternative part data for the knowledge data 230 in which the replacement approval or disapproval is recorded.
If proposed alternative part data that is not subjected to this process yet remains in the replacement proposal data in which the replacement approval or disapproval is recorded (“NO” at step S7-6), the management computer 21 returns the process to step S7-1 and performs the process on the next proposed alternative part data. The management computer 21 repeats the process from steps S7-1 to S7-6 until the process on all the proposed alternative part data is finished.
If the process on all the proposed alternative part data is finished (“YES” at step S7-6), the management computer 21 finishes this process.
As a consequence, the order data 240, in which the replacement proposal reflects, is registered in the order-data storage unit 24. In addition, the knowledge data 230 on the information as to whether use of the proposed alternative part is approved or disapproved and information on the part to be used by the customer is recorded in the knowledge-data storage unit 23.
The information on this order data 240 is transmitted to the next step. A person in charge of the next step accesses the operational support server 20 using the person-in-charge-of-next-step terminal 32 and performs an operation of the next step based on the order data 240.
If the customer who places the order for manufacturing printed boards changes the design, the customer transmits change request data from the customer terminal 40 to the person-in-charge terminal 30. The person in charge inputs change information on the order information based on this change request data using the person-in-charge terminal 30. The management computer 21 of the operational support server 20 performs a part-table registration process based on the input data (at step S8-1). Specifically, the management computer 21 records the order data 240 including the part table data in the change request data. In this case, the management computer 21 records the order data 240 in which the system version is upgraded from that included in the previously registered order data 240. The registered part table is displayed on the part table screen 60 displayed on the person-in-charge terminal 30 as shown in
The management computer 21 performs a part-table check process (at step S8-2). The part-table check process is performed similarly to the part-table check process at step S1-2 in the new registration process.
The management computer 21 specifies the previously registered part table corresponding to the part table (target part table) for which the change request is transmitted, as a reference part table. Specifically, the management computer 21 specifies the order data 240 having a latest version and a latest user version among pieces of order data 240 including the same customer name, board name, PWB part name, and PCB part name as the customer name, the board name, the PWB part name, and the PCB part name in the change-requested part table. It is noted that a system version allocated a greatest number is the latest system version. In addition, among the same system version, the system version corresponding to the user version allocated a greatest number is the Latest system version. Due to this, the order data 240 including the system version allocated the greatest number and the user version allocated the greatest number is specified as the order data 240 on the comparison target, previously registered part table. The management computer 21 performs a difference output process for a difference between the part table of the order data 240 thus specified and the change-requested part table (at step S8-3).
As shown in
If the part is an added or a deleted part (“YES” at step S9-2), the management computer 21 records difference part data on this part as a difference target part (at step S9-3). If the management computer 21 is to record the difference part data for the first time in the difference output process, the management computer 21 records the difference data 242 in which the customer name, the target-part-table identification information, and the standard table identification information are set. If the management computer 21 is to record the difference part data, the management computer 21 records the difference part data in the difference table data area of this difference data 242. Specifically, if the part is an added part, the management computer 21 records “added” as the difference type, and the part name and the like of the added part as the difference part data. If the part is a deleted part, the management computer 21 records “deleted” as the difference type, the part name and the like of the deleted part as the difference part data. The management computer 21 moves the process to step S9-4. If the part is not the added or deleted part (“NO” at step S9-2), the management computer 21 moves the process directly to step S9-4.
The management computer 21 checks whether the type number of this part is changed (at step S9-4). Specifically, the management computer 21 compares the type number of this part in the target part table with that in the reference part table. If the type number is changed (“YES” at step S9-4), the management computer 21 records difference part data as a difference target part (at step S9-5). Specifically, the management computer 21 records “type number changed” as the difference type, the part name, and the like. The management computer 21 moves the process to step S9-6. If the part number is not changed (“NO” at step S9-4), the management computer 21 moves the process directly to step S9-6.
The management computer 21 checks whether an address is added or deleted for this part (at step S9-6). Specifically, the management computer 21 compares the address information on this part included in the target part table with that in the reference part table. If the address is added or deleted (“YES” at step S9-6), the management computer 21 records difference part data as a difference target part (at step S9-7). Specifically, if the address is added, the management computer 21 records “address added” as the difference type, the part name, the added address, and the like. If the address is deleted, the management computer 21 records “address deleted” as the difference type, the part name, the deleted address, and the like. The management computer 21 moves the process to step S9-8. If the address is not added or deleted (“NO” at step S9-6), the management computer 21 moves the process directly to step S9-8.
The management computer 21 checks whether mounting or non-mounting of this part is changed (at step S9-8). Specifically, the management computer 21 compares information on mounting or non-mounting for each address of this part in the target part table with that in the reference part table. If the mounting or non-mounting of the part is changed (“YES” at step S9-8), the management computer 21 records difference part data as a difference target part (at step S9-9). Specifically, if mounting is changed to non-mounting, the management computer 21 records “changed from mounting to non-mounting” as the difference type, the part name, the target address, and the like. If the non-mounting is changed to the mounting, the management computer 21 records “changed from non-mounting to mounting” as the difference type, the part name, the target address, and the like. The management computer 21 then moves the process to step S9-10. If the mounting or non-mounting of the part is not changed (“NO” at step S9-8), the management computer 21 moves the process directly to step S9-10.
The management computer 21 checks whether a supplied part is changed for this part (at step S9-10). Specifically, the management computer 21 compares a setting of a supplied part flag for this part in the target part table with that in the reference part table. If the supplied part is changed (“YES” at step S9-10), the management computer 21 records difference part data as a difference target part (at step S9-11). Specifically, if the supplied part flag set in the reference part table is deleted in the target part table, the management computer 21 records “supplied part setting deleted” as the difference type, the part name, and the like. If the supplied part flag that is not set in the reference part table is set in the target part table, the management computer 21 records “supplied part changed” as the difference type, the part name, and the like. The management computer 21 moves the process to step S9-12. If the supplied part is not changed (“NO” at step S9-10), the management computer 21 moves the process directly to step S9-12.
If a part that is not subjected to this process yet remains in the target part table or a part for which a reference flag is not set in the reference part table is present (“NO” at step S9-12), the management computer 21 returns the process to step S9-1. If the part that is not subjected to this process yet remains in the target part table, the management computer 21 performs the process on the next part in the target part table. If the process on all the parts in the target part table is finished, the management computer 21 sequentially performs the process on the parts for each of which the reference flag is not set in the reference part table. The management computer 21 repeats the process from steps S9-1 to S9-12 until the process on all the part in the target part table is finished and the part for which the reference flag is not set in the reference part table is not present.
If the process on all the parts in the target part table is finished, the management computer 21 determines the part for which the reference flag is not set in the reference part table as a deleted part. At step S9-3, the management computer 21 records each of these parts as a difference target part. Specifically, the management computer 21 records “deleted” as the difference type and the part name for each of these parts.
If the process on all the parts in the target part table is finished and the part for which the reference flag is not set in the reference part table is not present (“YES” at step S9-12), the management computer 21 outputs a list of all the difference target parts (at step S9-13). Thus, a difference list screen 80 shown in
As shown in
The person in charge checks the difference list on this difference list screen 80 and clicks the OK button 85 when there is no problem. If the difference list is to be separately recorded, the person in charge clicks the store button 84. If the person in charge then clicks the OK button 85, the difference output process is finished.
The management computer 21 performs a part-information search process based on the difference data 242 output in the difference output process (at step S8-4). Specifically, the management computer 21 performs the same process as the part search process in the new registration process for the part of the difference type “added”.
The management computer 21 performs an alternative-part consideration process for the part of the difference type “added” (at step S8-5). Specifically, the management computer 21 performs the same process as the alternative-part consideration process in the new registration process for the part of the difference type “added”.
By performing these processes, the order data 240, in which the replacement proposal result reflects, for the added part is registered in the order-data storage unit 24. In addition, the knowledge data 230 on the information as to whether use of the proposed alternative part is approved or disapproved and the information on the part to be used by the customer is recorded in the knowledge-data storage unit 23.
The information on this order data 240 and that on the difference data 242 are transmitted to the next step. The person in charge of the next step accesses the operational support server 20 using the person-in-charge-of-next-step terminal 32, and performs an operation of the next step based on the order data 240 and the difference data 242.
If the common part data 220 registered in the common-part-data storage unit 22 is updated, the management computer 21 performs a common part table difference output process on each latest order data 240 of the registered order data 240. If the management computer 21 records the difference data 242, the management computer 21 outputs the difference data 242 while associating the difference data 242 with the part-table identification table constituted by the customer name, the board name, the PWB part number, the PCB part number, the system version, and the user version.
As shown in
If the address is added or deleted (“YES” at step S10-2), the management computer 21 records difference part data as a difference target part (at step S10-3). In this common part table difference output process, if the difference part data is first recorded, the management computer 21 records the difference data 242 in which the customer name and the target-part-table identification information are set. If the management computer 21 records the difference part data, the management computer 21 records the difference part data in the difference table data area of this difference data 242. Specifically, if the address is added, the management computer 21 records, as the difference part data, “address added” as the difference type, the added address, and the part name of the target part. If the address is deleted, the management computer 21 records, as the difference part data, “address deleted” as the difference type, the deleted address, and the part name of the target part. The management computer 21 moves the process to step S10-4. If the address is not added or deleted (“NO” at step S10-2), the management computer 21 moves the process directly to step S10-4.
The management computer 21 checks whether the replacement approval or disapproval is changed for the part of this order part data (at step S10-4). If the replacement approval or disapproval is changed (“YES” at step S10-4), the management computer 21 records difference part data as a difference target part (at step S10-5). Specifically, if the replacement approval or disapproval is changed to the replacement approval, the management computer 21 records “changed to replacement approval” as the difference type, and the part name. If the replacement approval disapproval is changed to the replacement disapproval, the management computer 21 records “changed to replacement disapproval” as the difference type, and the part name. The management computer 21 moves the process to step S10-6. If the replacement approval or disapproval is not changed (“NO” at step S10-4), the management computer 21 moves the process directly to step S10-6.
The management computer 21 checks whether the number of parts is changed for the part of this order part data (at step S10-6). If the number of parts is changed (“YES” at step S10-6), the management computer 21 records difference part data as a difference target part (at step S10-7). Specifically, the management computer 21 records “the number of parts changed” as the difference type, the part name, the number of parts before change, and the number of parts after change, and the like. The management computer 21 moves the process to step S10-8. If the number of parts is not changed (“NO” at step S10-6), the management computer 21 moves the process directly to step S10-8.
The management computer 21 checks whether the part number or type number is changed for the part of this order part data (at step S10-8). If the part number or type number is changed (“YES” at step S10-8), the management computer 21 records difference part data as a difference target part (at step S10-9). Specifically, if the part number is changed, the management computer 21 records “part number changed” as the difference type, the part number before change, the part number after change, and the part name. If the type number is changed, the management computer 21 records “type number changed” as the difference type, the type number before change, the type number after change, and the part name. The management computer 21 moves the process to step S10-10. If no part number or type number is changed (“NO” at step S10-8), the management computer 21 moves the process directly to step S10-10.
The management computer 21 checks whether supplied part information is changed for the part of this order part data (at step S10-10). If the supplied part information is changed (“YES” at step S10-10), the management computer 21 records difference part data as a difference target part (at step S10-11). Specifically, the management computer 21 records “supplied part deleted” as the difference type, the part name, and the like. The management computer 21 moves the process to step S10-12. If the supplied part is not changed (“NO” at step S10-10), the management computer 21 moves the process directly to step S10-12.
The management computer 21 checks whether customer comments are changed for the part of this order part data (at step S10-12). If the comments are changed (“YES” at step S10-12), the management computer 21 records the difference part data as a difference target part (at step S10-13). Specifically, the management computer 21 records “comments changed” as the difference type, the comments before change, the comments after change, the part name, and the like. The management computer 21 moves the process to step S10-14. If the comments are not changed (“NO” at step S10-12), the management-computer 21 moves the process directly to step S10-14.
The management computer 21 checks whether mounting or non-mounting is changed for the part of this order part data (at step S10-14). If the mounting or non-mounting is changed (“YES” at step S10-14), the management computer 21 records difference part data as a difference target part (at step S10-15). Specifically, if mounting is changed to non-mounting, the management computer 21 records “changed from mounting to non-mounting”, the part name, and the like. If non-mounting is changed to mounting, the management computer 21 records “changed from non-mounting to mounting”, the part name, and the like. The management computer 21 moves the process to step S10-16. If mounting or non-mounting is changed (“NO” at step S10-14), the management computer 21 moves the process directly to step S10-16.
If order part data that is not subjected to this process yet remains in the part table data included in the order data 240 (“NO” at step S10-16), the management computer 21 returns the process to step S10-1 and performs the process on the next order part data. The management computer 21 repeats the process from steps S10-1 to S10-16 until the process on all the order part data is finished.
If the process on all the order part data is finished (“YES” at step S10-16, the management computer 21 outputs a list of all of the recorded difference target parts (at step S10-17). Thus, the difference list screen accompanying the common part registration change is displayed on the person-in-charge terminal 30. The person in charge confirms this screen.
The management computer 21 performs a part-information search process and a replacement consideration process based on the difference data that is output to accompany this common part registration change. These processes are performed similarly to the part-information search process (at step S8-4) and the replacement consideration process (at step S8-5) in the change registration process, respectively.
The order data 240, in which the replacement proposal result reflects, is thereby registered in the order-data storage unit 24 for the difference data output to accompany the common part registration change. In addition, the knowledge data 230 on the information as to whether use of the proposed alternative part is approved or disapproved and the information on the part to be used by the customer is recorded in the knowledge-data storage unit 23.
The information on this order data 240 and that on the difference data 242 are transmitted to the next step. The person in charge of the next step accesses the operational support server 20 using the person-in-charge-of-next-step terminal 32, and performs an operation of the next step based on the order data 240 and the difference data 242.
The embodiment of the present invention can exhibit the following advantages. According to this embodiment, the management computer 21 searches the common-part-data storage unit 22 for the part in the part table data included in the order data 240 recorded in the order-data storage unit 24, and extracts the common part data 220 on the possible replacement common part. If the priority order of the approval status of the customer designated part is lower than that of the approval status of the possible replacement common part, the management computer 21 registers the possible alternative part in the replacement proposal. In this case, if the knowledge data 230 on this customer designated part for this customer indicates “disapproval” as the past customer approval or disapproval of replacement, the management computer 21 does not register the possible replacement common part in the replacement proposal. The management computer 21 submits the replacement proposal to the customer. The management computer 21 records data on the alternative part in the order-data storage unit 24 based on data on the reply to the replacement proposal, and records data on the customer approval or disapproval for this replacement proposal in the knowledge-data storage unit 23. By doing so, if the alternative part that can replace the customer designated part is extracted from among the common parts registered in the common-part-data storage unit 22 and proposed to the customer, and customer approval for this alternative part is obtained, this alternative part can be used. In addition, the management computer can make a replacement proposal while referring to the past customer approval or disapproval for the replacement proposal. Therefore, by replacing the customer designated part by the possible replacement common part, products can be provided at a low cost within a short delivery time using the common part.
Furthermore, according to this embodiment, the management computer 21 searches the knowledge-data storage unit 23 for each customer designated part recorded in the part table data. In addition, the management computer 21 extracts data on the previously proposed alternative part and the past replacement approval or disapproval if the part is recorded in the knowledge-data storage unit 23. If the past replacement approval or approval indicates “approval”, the management computer 21 selects this previously proposed alternative part as the proposed alternative part, and determines that the customer designated part is irreplaceable if the past replacement approval or disapproval indicates “disapproval”. It is thereby possible to propose the previously proposed and approved alternative part as an alternative part. If the proposed alternative part is previously proposed as an alternative part but disapproved, it is possible not to replace the customer designated part by the proposed alternative part. It is thereby possible to make the replacement proposal while causing information to be shared and intention of the customer to be reflected in the proposal.
According to this embodiment, the management computer 21 compares the part table data after the change by the customer with the part table data before the change recorded in the constituent part data storage unit 24, and outputs the difference data 242. The management computer 21 further performs the part-information search process and the alternative-part consideration process based on this difference data 242. It is thereby possible to allocate the common part and make the alternative part proposal only for a changed point between the part table data changed by the customer and the part table data before the change.
According to this embodiment, the common part data 220 includes data on the approval status. The management computer 21 displays information on the approval status on the person-in-charge terminal 30 based on the common part data 220 on the alternative part so as to urge the person in charge to consider the replacement. The management computer 21 also generates the replacement proposal data in which data on the replacement proposal approval or disapproval input using the person-in-charge terminal 30 reflects. It is thereby possible to support the person in charge when the person in charge considers the content of the replacement proposal.
This embodiment can be modified. According to this embodiment, the person in charge considers the proposed alternative part from among the searched possible alternative parts, and the part selected by the person in charge is proposed to the customer as the alternative part. Alternatively, if a plurality of possible alternative parts are searched and it is found that a plurality of possible proposed alternative parts are present as a result of a consideration of the person in charge, then the plural parts can be proposed to the customer as alternative parts and the customer can be able to select one alternative part from among the proposed alternative parts. The intention of the customer can be thereby reflected in the replacement proposal.
According to the embodiments described above, it is possible to provide a product at a low cost within a short delivery time.
Although the invention has been described with respect to a specific embodiment for a complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art which fairly fall within the basic teaching herein set forth.
