Description

  The present invention relates to a production plan adjustment support apparatus, a production plan adjustment support method, and a production plan adjustment support program. Specifically, the present invention provides easy-to-understand information on a production plan in a user-friendly manner, and simplifies the production plan. And a technology that enables efficient adjustment.

  Generally, a factory that produces a product drafts a production plan for producing the product by the required delivery date in order to meet the required delivery date of the market or customers. At that time, the plant production planner uses the production planning system to make a production plan. In this way, the existing production planning system includes master information such as bill of materials, process information, item information, standard lead time, and part receipt lead time, order information from the market, etc., and already planned production plans. Based on the transaction information such as information, inventory information of products and parts in the factory, and part order remaining information to suppliers, the parts and production capacity necessary for the production of the corresponding products are allocated, and the product production plan To plan. On the factory side, if the production plan prepared by such a production planning system satisfies the required delivery date of the market, the order from the market is accepted.

  However, in factories, various external and internal factors such as demand fluctuations such as express orders or order cancellations, requests for design changes from customers, and changes in production lines due to troubles in factory facilities occur every day. For this reason, there are cases where the production activity cannot be carried out according to the production plan prepared by the production planning system.

  At that time, the person in charge of production planning at the factory needs to adjust the production plan that has been formulated. And if the result of adjusting the production plan does not meet the required delivery date of the market, review the production capacity in the factory, for example, increase overtime hours or negotiate with the orderer to delay the delivery date It will be.

  As a technique for adjusting such a production plan, for example, an existing production plan including at least the completion date and the number of completed products, and a process including at least resources and usage amounts for each process used in manufacturing the product A storage means storing at least a master, resource capability information including at least the capability of the resource, a scheduler for creating pegging information of the existing production plan, and an increase request including at least a desired completion date and a desired number of completions of the product An increase request input receiving means for receiving an input of an order, a resource that becomes insufficient in capacity when the increase request is added to the existing production plan, and a capacity shortage amount are calculated for each time bucket. Reduction candidate extraction means for extracting an order of the existing production plan that shares a bucket with the increase request order as a reduction candidate Have been proposed, such as production plan adjustment system with a (see Patent Document 1).

  By the way, in general, production planners can adjust production plans in the production planning system by changing the delivery date of existing production plans, such as orders received, quotes, and inquiries, and production at production sites. This includes reviewing capabilities and changing the storage schedule for parts. However, there are the following problems when adopting such an adjustment method.

  For example, if the delivery date is changed in the existing production plan, there is a problem that it is impossible to meet the customer's requested delivery date, resulting in a loss of sales opportunities. In addition, since the capacity of the production site is limited, there is also a problem that an unrealizable production plan is drawn up if the production capacity is increased beyond the actual level to meet market demands. In addition, frequently changing the storage schedule of parts causes a problem of production confusion on the part supplier side.

  On the other hand, when executing such adjustments in the production planning system, the production planner needs to perform a number of screen transitions in order to confirm various information and set values, and the production planner's workload And the labor cost for that would be large. Further, if the existing production plan is deleted and an increase desired order is accepted as in the conventional technique, there is a concern that a problem that cannot satisfy the customer request of the order in the existing production plan may occur.

  Accordingly, an object of the present invention is to provide a technique that presents information on a problematic production plan to a user in an easy-to-understand manner and enables simple and efficient adjustment to the production plan.

It shall be.

  The production plan creation unit 41 acquires the parts table 31, item information 32, process information 33, standard lead time, and minimum production possible lead time 34 from the master information storage unit 30 of the auxiliary storage device 11, and the auxiliary storage device. 11 is a function for acquiring the existing production plan 35, the inventory information 36, the remaining order information 37, and the order information 38 from the transaction information storage unit 40, and generating a production plan. It can be said that the production plan creation unit 41 is configured by a production planning technique that has conventionally existed.

  On the other hand, the production plan adjustment unit 42 reads each information of the existing production plan 35 related to the predetermined product held by the auxiliary storage device 11 and the adjusted production plan 43 held by the main storage device 13 and completes the work in the same process. The time divergence is calculated between the existing production plan 35 and the adjusted production plan 43, the calculation result is output to the client terminal 50 (or display device), and the resource adjustment instruction for eliminating the divergence Is generated from the client terminal 50 (or the input device), and a production plan with the resource information adjusted according to the adjustment instruction is generated using the production plan generation unit 41.

  Further, the production plan adjustment unit 42 reads information on the existing production plan 35 from the auxiliary storage device 11 and calculates the load status and the delivery date compliance rate for each predetermined period included in the information of the production plan 35. The data may be extracted and output to the client terminal 50 (or display device).

  In addition, the production plan adjustment unit 42 gives an instruction specifying a predetermined time when the delivery date compliance rate is equal to or less than a predetermined standard according to the load status and delivery date compliance rate output processing described above. From the existing production plan 35, the client terminal 50 (or display device) extracts the information received from the input device) from the existing production plan 35 for the order scheduled to be dealt with in each process at the relevant time and the required delivery date and work completion time planned for the relevant order. ).

  In addition, the production plan adjustment unit 42 receives an instruction from the client terminal 50 (or input device) that designates a predetermined order that causes a delay in the delivery date according to the output processing of the requested delivery date and work completion time information. The divergence calculation described above with respect to the corresponding order may be executed.

  In this case, the production plan adjustment unit 42 generates a Gantt chart screen showing the transition of the work completion time in each process corresponding to the corresponding order in each of the existing production plan 35 and the adjusted production plan 43, and the Gantt chart. The calculation result of the above-described deviation may be set in the display of each process on the screen and output to the client terminal 50 (or display device).

  Further, the production plan adjustment unit 42 receives an instruction designating a predetermined process in which the above-described divergence is generated from the client terminal 50 (or input device) in accordance with the output processing of the above-described Gantt chart screen. Even if a resource adjustment instruction regarding the received process is received from the client terminal 50 (or input device) and a production plan with the resource information adjusted according to the adjustment instruction is generated using the production plan creation unit 41 Good.

  In addition, the production plan adjustment unit 42 specifies an order in which the work completion time in each process is retroactive before the reference date for formulating the production plan in the above-described output processing of the Gantt chart screen, Calculate the retroactive days (hereinafter referred to as the past split days) from the base date of the work completion time in the relevant order, and the standard lead time of each process corresponding to the order and the minimum lead time of the resource information Each information is acquired from the auxiliary storage device 11, a value obtained by subtracting the minimum lead time from the standard lead time is calculated for each process, the calculated values are added up for all processes corresponding to the order, and the Gantt chart screen is displayed. The calculated past number of days and the calculation result of the sum may be set and output to the client terminal 50 (or display device).

  The production plan adjustment unit 42 may generate a production plan using the production plan creation unit 41 using the above-described minimum lead time acquired from the auxiliary storage device 11 as information on the adjusted resource.

  The client terminal 50 connected to the device 10 via the network 100 includes hardware and software as a general computer terminal. In addition, the client terminal 50 includes a display processing unit 51 as a function to be implemented by executing a program. The display processing unit 51 generates a load status confirmation screen, a delivery delay order list screen, a production capacity and standard work time setting screen, and a production plan adjustment pre- and post-screen (both will be described later in detail). (Not shown). The person in charge of production planning can view the above-mentioned screens and confirm the contents thereof, confirm the production plan in question, examine the countermeasure policy, and adjust the production plan.

  Here, the adjustment work flow executed by the person in charge of production planning who uses the apparatus 10 of the present embodiment at the client terminal 50 will be described. FIG. 2 is a diagram showing a flow example of the plan adjustment work of the planner in this embodiment. In this case, the person in charge of production planning first grasps (101) the entire production plan and confirms that there is no problem in the produced production plan. After confirming this, the person in charge of the production plan grasps (102) the production plan that cannot actually be adopted (becomes NG), and confirms the order of the production plan that actually has a problem. Subsequently, the person in charge of production planning confirms the contents of the production plan and the adjusted production plan for the corresponding order, and grasps the process (hereinafter referred to as a shop) having a problem. The person in charge of production planning checks the number of days of deviation between the production plan and the adjusted production plan, the load factor for each shop date, and reviews (103) the countermeasure policy. Finally, the person in charge of production planning adjusts and reconfirms (104) the production plan based on the examination contents of the countermeasure policy.

  Hereinafter, with respect to the actual procedure of the production plan adjustment support method in the present embodiment, processing executed by the apparatus 10 in parallel with the flow of the adjustment work flow (FIG. 2) will be described with reference to the drawings. Various operations corresponding to the production plan adjustment support method described below are realized by the program 12 that the apparatus 10 reads into the main storage device 14 and executes. And this program 12 is comprised from the code | cord | chord for performing various operation | movement demonstrated below.

  FIG. 3 is a diagram showing a flow example 1 of the production plan adjustment support method according to the present embodiment. In this case, the apparatus 10 reads the information of the production plan 35 from the auxiliary storage device 11, extracts the load status and the delivery date compliance rate for each predetermined period included in the information of the production plan 35, and Is generated, and the screen data is output to the client terminal 50 (400).

  FIG. 4 is a diagram showing a screen configuration example 1 (load status confirmation screen) in the present embodiment. This load status confirmation screen 201 is an example of the screen data output to the client terminal 50 in step 400 described above. The screen 201 is a screen used when the person in charge of production planning grasps the entire production plan in step 101 of the adjustment workflow described above. The screen configuration of the screen 201 includes a load factor 202 for each shop date and a delivery date compliance rate 203 for each date. In the example of FIG. 4, “2/5”, that is, the delivery date compliance rate 203 on February 5, is “80”. That is, if the delivery date compliance rate 203 is less than 100, it means that a certain shop has a problem and the required delivery date of the market cannot be satisfied.

  Further, in step 400 described above, the apparatus 10 receives from the client terminal 50 an instruction specifying a predetermined time when the delivery date compliance rate is equal to or lower than the predetermined standard (less than 100) on the screen 201 described above. In the example of the screen 201 described above, it is assumed that the person in charge of production planning clicks on the client terminal 50 where the delivery date compliance rate 203 is less than 100. In response to this click operation, the device 10 receives, for example, the order scheduled to be dealt with at each shop at the corresponding time of “2/5”, and information on the requested delivery date and work completion time planned for the relevant order. The screen including the relevant information is extracted, and the relevant screen data is output to the client terminal 50.

  FIG. 5 shows an example of a screen including information on the above-mentioned required delivery date and work completion time. FIG. 5 is a diagram showing a screen configuration example 2 (delivery date delayed order list screen) in the present embodiment. The delivery delay order list screen 301 is a screen used when the person in charge of production grasps the production plan to be NG in the step 102 of the adjustment workflow described above. The screen configuration of this screen 301 is made up of information on customer requested delivery date 304 and actual production plan completion date 305 (that is, work completion date) for each item 303 that is NG of each order 302.

  The apparatus 10 accepts a click on an order 302 on the screen by the production planner via the client 50 on the screen 301 described above (401). In the example of the screen 301 described above, it is assumed that the person in charge of production planning clicks “Order0001” in the order 302 on the client terminal 50. Upon receiving this click operation, the apparatus 10 receives the existing production plan 35 associated with the order 302 designated by the person in charge of production planning in the auxiliary storage device 11 or the production plan creation unit 41 of the main storage device 14. A search is performed for existence (401).

  Subsequently, in step 402, the apparatus 10 determines whether there is production plan data associated with the order 302 as a result of the search for the existing production plan 35. As a result of this determination, there is production plan data associated with the corresponding order. If so (step 402: Y), the process proceeds to step 403. On the other hand, when there is no production plan data associated with the order (step 402: N), the apparatus 10 ends the process.

  Next, in step 403, the apparatus 10 acquires the production start date and the production end date included in the existing production plan 35 that has been identified by the above-described search, and stores it in the main storage device 13. In step 404, the apparatus 10 searches the production plan adjustment unit 42 of the main storage device 14 to find out whether there is an adjusted production plan 43 associated with the order 302 designated by the person in charge of production planning. Do. In step 405, as a result of searching the adjusted production plan 43 as described above, the apparatus 10 determines whether there is data of the adjusted production plan 43 associated with the order 302 designated by the person in charge of production planning. If the result of this determination is that there is data for an adjusted production plan (step 405: Y), the apparatus 10 advances the process to step 406. On the other hand, when the data of the adjusted production plan 43 does not exist (step 405: N), the apparatus 10 ends the process.

  Subsequently, in step 406, the apparatus 10 acquires values of the production start date and the production end date from the adjusted production plan 43 specified by the above search, and stores them in the main storage device 13.

  In step 407, the apparatus 10 uses the production start date and the production end date of the existing production plan 35 and the adjusted production plan 43 stored in the main storage device 13 in steps 403 and 406 described above. For each shop, the number of days of divergence is calculated by subtracting the production start date in the existing production plan 35, that is, the production end date before adjustment, from the production start date in the adjusted production plan 43, that is, the adjusted production start date.

  Next, in step 408, the apparatus 10 receives the standard work time of the process information 33 stored in the master information storage unit 30 of the auxiliary storage device 11 and the order stored in the transaction information storage unit 40 of the auxiliary storage device 11. Based on the quantity of the information 38, the load factor is calculated for each shop date. Since this load factor calculation method is an existing method, details are omitted.

  Subsequently, in step 409, the apparatus 10 determines whether the production plan before adjustment (the production start date) is retroactively before a predetermined reference date. As a result of the determination, if the production plan is retroactive before the reference date (step 409: Y), the apparatus 10 advances the processing to step 411. On the other hand, when the production plan does not exist in the past from the reference date (step 409: N), the apparatus 10 advances the process to step 410. In step 410 described above, the device 10 performs display processing of the Gantt chart screen of FIG. 6, while in step 411, the device 10 performs screen display processing of FIGS.

  In step 410, the apparatus 10 changes the production end date (work completion time) at each shop corresponding to the order 302 designated by the person in charge of the production plan in each of the existing production plan 35 and the adjusted production plan 43. A Gantt chart screen (FIG. 6) is generated, and the calculation result of the divergence days is set in the display of each shop on the Gantt chart screen and output to the client terminal 50.

  FIG. 6 is a diagram showing a screen configuration example 3 (screen before and after production plan adjustment) in the present embodiment. This production plan adjustment pre- and post-screen 501 corresponds to the above-described Gantt chart screen, and is a screen used when a production planner examines a countermeasure policy in step 103 of the above-described adjustment workflow. The screen configuration of the screen 501 includes a Gantt chart 502 and a Gantt chart 503 based on the existing production plan 35 and the adjusted production plan 43, an existing production plan 35, that is, an order 504 before adjustment of the production plan, an adjusted production plan 43, that is, a production plan. It consists of the adjusted order 505, the load factor 506 for each shop date, and the number of divergence days 507 calculated in step 407.

  Here, the adjustment work flow of the person in charge of production planning after configuring the screen 501 of FIG. 6 will be described. FIG. 7 is a diagram showing a flow example 2 of the production plan adjustment support method according to the present embodiment. In this case, the person in charge of production planning browses the production plan adjustment before and after screen 501 shown in FIG. 6, confirms the number of days of divergence for each shop, and confirms the problem level of the production plan (601).

  Next, the person in charge of production planning confirms the load factor for each shop date on the above-described screen 501 (602). In addition, after confirming the load factor in step 602, the production planner reviews the production capacity or standard work time (resource adjustment instruction) using the screen of FIG. 8 (603). Since the production plan is regenerated in the apparatus 10 using the setting value (that is, the resource information after adjustment according to the resource adjustment instruction) that the production plan person has reviewed, the production plan person The production plan as the generation result is confirmed, and it is confirmed again whether the above-mentioned problem has been solved (604). If it is determined in step 604 that the problem has been resolved, the production planner ends the plan adjustment. On the other hand, if it is determined that the problem cannot be solved, the production planner returns to step 603 to review the production capacity and the standard work time again. By repeatedly performing the adjustment operations in steps 603 and 604, the person in charge of production planning solves the problem of the production plan.

  On the other hand, the apparatus 10 side outputs the production capacity and standard work time setting screen 700 of FIG. 8 to the client terminal 50 in step 410 described above, corresponding to step 603 in the adjustment work flow of the production planner. The above-described production capacity or standard work time review (resource adjustment instruction) is accepted via this screen 700.

  The production capacity and standard work time setting screen 701 will be described. FIG. 8 is a diagram showing a screen configuration example 4 (production capacity and standard work time setting screen) in the present embodiment. The production capacity and standard work time setting screen 701 is a screen used in the adjustment work flow 603 of the person in charge of production planning. The screen configuration includes a target shop 702, a production capacity 703 for each shop stored in the process information 33 in the master information storage unit 30 of the auxiliary storage device 11, a standard work time 704, a production capacity input field 705, A standard work time input field 706 and a determination button 707 are included. When the person in charge of production planning presses the decision button 707 on the client terminal 50, the apparatus 10 acquires the value of the production capacity 705 or the standard work time 706 inputted by the person in charge of production planning, and adjusts this value to the resource. As a command, production plan generation is re-executed.

  FIG. 9 is a diagram showing an example of data before and after the change of the production capacity and the standard work time in this embodiment. The state before and after the change of the value obtained by the apparatus 10 via the above-described screen 701 in FIG. 8 is shown. 9 is stored in the process information 33 in the master information storage unit 30 of the auxiliary storage device 11, and the production capacity (before change) 802 for each shop 801. Data on production capacity (after change) 803, standard work time (before change) 804, and standard work time (after change) 805 are included.

  As described above, the apparatus 10 which has obtained the deemed values of the production capacity and the standard work time, in step 410, in the master information storage unit 30 and the transaction information storage unit 40 based on the review value (resource adjustment instruction). A production plan is generated again with a value obtained by correcting the correspondence information. FIG. 10 is a diagram showing a screen configuration example 5 (plan adjustment result screen) in the present embodiment. The production plan generated according to the review value is generated as a Gantt chart screen in the screen 901 before and after the plan adjustment exemplified in FIG. This production plan adjustment pre- and post-screen 901 shows the result of the apparatus 10 adjusting the production plan based on the values set by the planner on the screen 701. In this screen 901, the load factor 902 after the plan adjustment is displayed for each date of each shop, and the Gantt chart 903 after the production plan adjustment and the order 904 after the production plan adjustment are displayed.

FIG. 13 is a diagram showing a flow example 3 of the production plan adjustment support method according to the present embodiment. Here, a screen display procedure for each value of the planned number of days before the reference date and “standard LT—minimum LT that can be produced” will be described.

  When displaying the screens of FIGS. 6, 12, and 18, the apparatus 10 calculates the number of plans before the reference date and the value of “standard LT−minimum LT that can be produced”. First, in step 1101, the apparatus 10 compares the start date 1203 with the reference date 1205 based on the required amount development result of the parts calculated by the production plan creation unit 41 (FIG. 14: based on the existing technology), and starts the start date. <If it is a reference date, it is determined that the plan is before the reference date, and the number of plans is counted, and the counted number of plans is stored in the main storage device 13.

  In step 1102, the apparatus 10 determines whether or not the number of plans stored in the main storage device 13 in step 1101 is one or more. If the number of plans is one or more (step 1102: Y), the process proceeds to step 1103. If the number of plans is 0 (step 1102: N), the process ends.

  In step 1103, the apparatus 10 determines that the production completion date 1204 (production start date) is before the reference date 1205 or the production completion date 1204 (production end date) is the reference date 1205. In the case of the same day, the planned number of days is calculated by “finishing date 1204-start date 1203” and stored in the main storage device 13. In the example of FIG. 14, since the start date of the production plan of the shop 3 is before the reference date, calculating “finishing date−start date” results in “1 day”. If the production completion date 1204 of the production plan is in the future from the reference, the device 10 calculates the planned number of days by “reference date 1205 -start date 1203” and stores it in the main storage device 13. Further, the device 10 calculates the total number of planned days stored in the main storage device 13.

  FIG. 14 is a diagram illustrating an example of data of a required amount development result according to the present embodiment. The required amount expansion result is stored in the production plan information in the production plan creation unit 41 of the main storage device 13, and items 1202 to be produced for each shop 1201, production start date 1203, completion date 1204, and reference date 1205. Is stored.

  Subsequently, in step 1104, the apparatus 10 acquires the standard lead time (hereinafter, all lead times are LT) of each shop of the production plan linked to the order from the master data shown in FIG. In step 1105, the minimum producible LT for each shop in the production plan associated with the order is acquired from the master data shown in FIG. FIG. 15 is a diagram showing a setting example of the standard lead time and the minimum production possible lead time according to the present embodiment. The data of the standard LT and the minimum producible LT is stored in the process information 33 in the master information storage unit 30 of the auxiliary storage device 11, and in the example shown in FIG. 15, the standard LT 1302 and the minimum producible minimum for each shop 1301. The LT 1303 is stored.

  Subsequently, in step 1106, the apparatus 10 performs subtraction of the minimum LT that can be produced from the standard LT acquired in steps 1104 and 1105 described above, that is, “standard LT−minimum LT that can be settled” for each shop.

  Next, in step 1107, the apparatus 10 calculates the total number of “standard LT-minimum LT that can be produced” for each shop calculated in step 1106 described above, and calculates the number of days of production planning associated with the order. In step 1108, the apparatus 10 calculates the total number of “days” calculated in step 1103 described above, the planned number of days before the reference date, and “standard LT−minimum LT that can be produced” calculated in step 1107. Displayed on the screen before and after the plan adjustment (FIG. 12).

  Here, an adjustment flow 1500 for the person in charge of production plan accompanying the output of the screen before and after the production plan adjustment in FIG. 12 will be described. FIG. 16 is a diagram showing a flow example 2 of the plan adjustment work of the planner in the present embodiment. In this case, in step 1401, the person in charge of production planning confirms the sum of the past split days and the sum 1002 of “standard LT−minimum producible LT” on the screen of FIG. 12, and “Σ past split days ≦ Σ (standard LT If “−minimum producible LT)”, go to step 1402, and if “Σ past split days> Σ (standard LT−minimum producible LT)”, the adjustment work is terminated. In Step 1402, the person in charge of production planning activates the production plan adjustment unit 42 again to regenerate the production plan. In step 1403, the person in charge of production planning checks the result regenerated in step 1402 on the screen of the client terminal 50, and determines whether or not the problem has been solved.

  For example, in the above adjustment flow, corresponding to the case where “Σ past split days ≦ Σ (standard LT−minimum LT that can be produced)”, the apparatus 10 in step 411 described above adjusted the minimum lead time. An instruction for resource information is received from the client terminal 50 (may be autonomously performed), a process for generating a production plan is further executed, and a screen before and after the plan adjustment as a result is output on the client terminal 50. It becomes.

  FIG. 17 is a diagram showing a screen configuration example 8 (screen before and after plan adjustment) in the present embodiment. In this case, the production plan adjustment before and after screen 1501 output from the client terminal 50 displays the adjustment result of the production plan using the minimum production possible LT. The load factor 1502 on the production plan adjustment before and after screen 1501 displays the load factor after the production plan adjustment for each date of each shop. A Gantt chart 1503 on the production plan adjustment before and after screen 1501 displays the production plan of the order based on the information in the screen display step 403. The person in charge of the production plan checks the screen 1501 before and after the production plan adjustment at the time of step 1404 in the adjustment flow, and determines whether or not the problem has been solved.

  Other examples of the delivery date delayed order list screen and the screen before and after the production plan adjustment will also be described. FIG. 18 is a diagram showing a screen configuration example 9 (delivery date delayed order list screen) in the present embodiment. The delivery date delayed order list screen 301 shown in FIG. 18 is a screen used when grasping a production plan that becomes NG in step 102 in the adjustment workflow as described above. When one of the orders 302 whose delivery date is delayed is clicked on the client terminal 50, the apparatus 10 performs a transition to the screen of FIG. 6, FIG. 12, or FIG.

  FIG. 19 is a diagram showing a screen configuration example 10 (screen before and after production plan adjustment) in the present embodiment. The production plan adjustment pre- and post-view 1601 shown in FIG. 19 is a screen used when the person in charge of production planning examines the countermeasure policy in step 103 in the adjustment work flow as described above. In the screen in this case, the production plan of the order is displayed on the Gantt chart 1605 based on the information in the screen display step 403 of the order 1602 selected by the production planner for each shop. Further, the production plan after adjustment of the order is displayed in the Gantt chart 1606 based on the information in the screen display step 406 of the order selected by the production plan person in charge on the delayed delivery order list screen for each shop. Further, on this screen, an order 1602 before the production plan adjustment and an order 1603 after the production plan adjustment are displayed. Also, on this screen, the load factor 1604 for each shop date is displayed based on the information of the screen display step 408, and the number of days of deviation before and after the production plan adjustment is displayed based on the information of the screen display step 407. Is done. In the screen configuration of FIG. 19, the number of divergence days is “4 days” for “Shop 1”, “3 days” for “Shop 2”, and “1 day” for “Shop 3”. In this case, when the plan adjustment is performed by the production plan adjustment unit 42 of the apparatus 10, the load factor on the date on which the plan should be originally planned is 100%, and the result adjusted in the future from the date on which the plan should be originally planned Is displayed. In the case of FIG. 19, since there is a large difference between before and after the adjustment of the production plan, the person in charge of the production plan not only performs re-simulation using the minimum production possible LT, but also on the production capacity and standard work time setting screen of FIG. The production plan is adjusted by changing the production capacity and standard work time of each shop. The apparatus 10 receives the adjustment instruction from the person in charge of the production plan and re-executes the production plan.
