This work plan creation device is provided with: a storage unit for associating and storing multiple work processes involved up to delivery of a product, work completion times of the work processes, and training times showing the time needed for a worker to learn operations of the work processes; a production capability calculation unit which, when a product is produced following work processes, determines for each work process the work processes in which delays occur; a personnel assignment unit which assigns workers to work processes in which delays are occurring, calculates the training completion time of the workers who have been assigned on the basis of the training times, and calculates for each work process the work process work completion time when the worker training completion time is applied; a production simulation unit which, on the basis of the work completion time of each work process calculated by the personnel assignment unit, simulates whether the work processes up to product delivery will be in time for delivery; and a production plan evaluation unit which selects the optimal work process from the work processes simulated by the production simulation unit.

Description

Work plan creation device and work plan creation method

The present invention relates to a work plan creation device and a work plan creation method for creating a work plan including a plan for training workers related to on-site manufacturing in relation to a production plan drafting operation for individually ordered products such as industrial machines, motors and elevators. It is about.

Conventionally, in manufacturing processes that require work by workers, techniques for optimizing worker assignment to each work have been developed for the purpose of achieving production targets such as target production volume and customer delivery date. In addition, with the diversification of customer needs, multi-product production, in which a plurality of products are manufactured on the same production line, has become mainstream. In multi-variety production, workers need to be multi-skilled in order to cope with work contents such as processing methods and equipment used depending on the product type. In addition, it is necessary to create a worker assignment plan. In the worker assignment plan, the worker is preferentially assigned to work that can be mastered based on the work list that each worker has mastered. Recently, worker assignment technology that achieves both the production goal achievement and the worker development goal achievement has been developed.

For example, in Patent Document 1, for multi-product production processes, element work is integrated within a range that does not exceed the tact time from the tact time calculated from the shipment plan for each product type and the standard work time of element work. Describes worker assignment technology that achieves target production and maximizes working time for unfamiliar work by assigning work to workers whose total work time of integrated elemental work is less than or equal to the tact time. Has been.

Many of the operations for individual order products such as processing and welding often depend on skills that require long-term education. Therefore, when orders are increasing, there is a problem that there is a shortage of workers having necessary skills when planning a large schedule. For example, in the case of individual orders such as plant construction and large machine parts, the required welding qualifications and operation of mechanical equipment differ depending on the product. At the same time, it is necessary to consider the lack of skills. However, in Patent Document 1, which is the prior art, it is possible to grasp the shortage of workers, but it is impossible to quantitatively present to which worker what work needs to be trained.

The purpose is to identify the skill as a factor, and to simultaneously create a work plan including a worker training plan with necessary work skills and a worker assignment plan.

In order to solve the above-described problems and achieve the object, the work plan creation apparatus according to the present invention includes a plurality of work processes until a product is delivered, work completion times of the work processes, and workers. Is a storage unit that associates and stores a training period indicating a period necessary for learning each work of the work process, and when the product is produced according to the work process, there is a delay in delivery for each work process. A production capacity calculation unit that identifies the work process that occurs, assigns the worker to the work process that is delayed in delivery, determines the training completion time of the worker assigned based on the training period, and A worker assignment unit that determines the work completion time of the work process for each work process when the training completion time of the worker is applied, and the work completion for each work process obtained by the personnel assignment part A production simulation unit for simulating whether the work process until delivery of the product is in time for delivery, and a production plan evaluation unit for selecting an optimal work process from the work processes simulated by the production simulation unit And.

Further, the present invention is a work plan creation method performed by the work plan creation device.

According to the present invention, it is possible to create a work plan for a product in consideration of a worker's training plan when production indicators such as production volume and delivery date compliance deteriorate due to lack of skills of the worker. It becomes.

Note that the worker training plan information described above is stored in advance, for example, in the work plan creation device 110 shown in FIG.

Next, the processing program executed by the work plan creation apparatus 110 in the present embodiment will be described in order with reference to FIG. FIG. 12 is a flowchart showing a process of creating a production plan executed by the work plan creating apparatus 110 according to the present invention.

First, the information acquisition unit 1111 receives, as input data, each product received from the storage unit 115 (hereinafter also referred to as a planning target product and a target product), facility information, production capacity information, process route information, and facility operating time information. Read (S10). Next, the necessary production capacity calculation unit 1112 performs a production simulation from the present to the future, and evaluates whether the delivery date of each product is in time (S20). Next, the worker assignment unit 1113 creates a worker assignment plan from the worker-specific training information and the process-specific training information (S30). The production simulation unit 1114 performs a production simulation from the present to the future using a plurality of work plans, and evaluates whether the delivery date of each product is in time (S40). Next, the worker training planning unit 1115 outputs the simulation result of step S40 (S50). Details of steps S20 to S40 will be described with reference to FIGS. 13A to 15. The output result of step S50 will be described in detail with reference to FIG.

Then, the production plan evaluation unit 1116 selects an optimal worker training plan for the output result of step S50 based on threshold values such as a preset delivery date compliance rate and total overtime hours (S60). The work instruction unit 1117 transmits the worker training plan selected in step S60 to the production line management device 130 via the network 190, and causes all the devices to adopt the worker training plan selected this time (S70). . When the process of step S70 ends, all the processes shown in FIG. 12 end. In this way, a product production plan is created in accordance with the changed work plan in consideration of the worker's training plan while observing the delivery date from the customer.

FIG. 13A is a flowchart showing a process for calculating the necessary production capacity in step S20 in FIG.

First, the required production capacity calculation unit 1112 refers to the order target product (product number) stored in the storage unit 115 and the plan target product (product number) and the process route information illustrated in FIG. Information on processes necessary for the product is fetched (S201).

Next, the necessary production capacity calculation unit 1112 determines an assignment plan of work until the target product is completed based on work plan information (not shown) of a predetermined product (S202). The necessary production capacity calculation unit 1112 repeats the processing steps S204 to S209 for the number of all products in order to formulate work allocation plans for all products stored in the order information storage unit 1151 (S203). Further, the necessary production capacity calculation unit 1112 repeats the processing steps S205 to S207 by the number of all processes in order to make an allocation plan for the target product (S204).

Next, the required production capacity calculation unit 1112 confirms whether there is equipment that can be used at the relevant date and time of the target product and target process (S205).

Specifically, after the product having the product number stored in the order information shown in FIG. 3 performs the process stored in the work performance information shown in FIG. 5, the product is stored in the process route information shown in FIG. When performing the performed process, it is determined whether there is a usable equipment among the equipment stored in the equipment operation information shown in FIG.

For example, for the product with the product number “product A” in the order information shown in FIG. 3, “process 2” is completed on “January 29” in the work performance information shown in FIG. Is completed on “January 30”. At this time, the required production capacity calculator 1112 refers to the process route information shown in FIG. 6 with “process 3” as a key when performing the process of “process 3”, and the equipment capable of performing “process 3”. It is understood that “2” units “equipment 302” and the working time is “7” hours. The necessary production capacity calculation unit 1112 refers to these pieces of information and refers to the equipment operation information shown in FIG. 7 to determine whether or not the “equipment 302” necessary for performing “process 3” can be used. To do.

If there is no equipment that can be used (S205; No), the required production capacity calculation unit 1112 proceeds to step S206, advances the corresponding date and time by the unit time (S206), and returns to step S205. The process of determining whether there is a usable facility is repeatedly performed. On the other hand, if there is a usable facility (S205; Yes), the necessary production capacity calculation unit 1112 proceeds to step S207, assigns the corresponding product to the usable facility, and sets the corresponding date and time for the work time (for example, In the case of “Step 3”, the work time is “7” hours, so that time) is advanced (S207).

In this way, the necessary production capacity calculation unit 1112 repeats the processing steps S205 to S207 as many times as the total number of processes in order to plan the target product (S208). Finally, the target product is delayed from the delivery date. (S209). When the necessary production capacity calculation unit 1112 confirms whether or not there is a delay for the target product, the delivery delay detection simulation unit 1112 is stored in the order information of FIG. 3 in order to plan all target products. The processing steps S204 to S209 are repeated for all the other products by the number of all processes (S210). When the process of step S210 is finished, all the processes shown in FIG. 13A are finished.

When the process shown in FIG. 13A ends, as shown in FIG. 13B, the timing for completing each process is known for each product, and the delivery date of each product (for example, in the case of product A, the final process is “ It can be seen that “process n” is the delivery date, and the production of product A is scheduled to be completed on “February 19”. Further, as shown in FIG. 13C, for example, in the case of the product A, it is possible to know when and in which equipment each process is completed, and it is possible to confirm whether there is a delay with respect to the delivery date. In the example shown in FIG. 13C, only product A is shown, but the same information can be obtained for all products stored in the order information.

FIG. 14 is a flowchart showing a process for calculating the worker personnel assignment unit in step S30 in FIG.

First, the worker personnel assignment unit 1113 takes in the worker-specific training information 1156 shown in FIG. 8 and the process-specific training information 1157 shown in FIG. 9 stored in the storage unit 115 (S301).

Next, the worker personnel assignment unit 1113 takes in the information stored in the storage unit 115 regarding the target product whose delivery date is delayed in step S20 (S302). The worker personnel assignment unit 1113 repeats the processing steps S304 to S311 as many times as the number of all target processes that have been delayed in step S20 (S303), and further, the worker personnel assignment unit 1113 stores the worker information stored in the worker-specific training information in FIG. The processing steps S305 to 310 are repeated by the number (S304).

Then, the worker personnel assignment unit 1113 extracts workers who are targets for worker training from the worker-specific training information (S305). Specifically, the target worker is extracted using the “process” of the worker-specific training information shown in FIG. 8 as a key. For example, when the process whose delivery is delayed is “process 3”, the worker-specific training information shown in FIG. 8 is referred to, and the worker who cannot yet take charge of “process 3” (that is, other than “process 3”) A record including “worker A” and “worker C”, which is a worker who can take charge of the process (2) is extracted.

Next, the worker personnel assignment unit 1113 determines the training period from the “similar process” in the process-specific training information (S306). For example, when the process whose delivery date is delayed is “process 3”, the worker staff assignment unit 1113 uses the “process 3” as a key and the “similar process” of the process-specific training information shown in FIG. , “None” and “Process 1” are selected. The worker staff assignment unit 1113 determines the training period by combining this information and the process of training information for each worker of “worker A” and “worker C” extracted in S304. In the example shown in FIGS. 8 and 9, “worker A” has work experience in “process 2” and “worker C” has work experience in “process 1”. Since “person A” has no experience of “process 1” similar to “process 3” that is delayed in delivery, the worker personnel assignment unit 1113 displays “similar process” in the process-specific training information shown in FIG. Select the training period “4 months” corresponding to “None”. In addition, since “worker C” has work experience of “process 1” similar to “process 3” that is delayed in delivery, the worker personnel assignment unit 1113 trains by process shown in FIG. The growing period “3 months” corresponding to “process 1” of “similar process” in the information is selected.

Next, the worker personnel assignment unit 1113 repeats the processing steps S308 to S309 by the number of all workers whose training period is selected in order to plan the target product (S307).

Next, the worker personnel assignment unit 1113 creates a plan (worker assignment plan) in the case where a trained worker is assigned to the target process in which the delivery date is delayed (S308). Specifically, for example, when “Process 3” is delayed in delivery date, the worker personnel assignment unit 1113 is the worker extracted in Step S305 for “Process 3”. From the start time (for example, 4/1) at which the delivery delay of “Process 3” has occurred with respect to the worker “A”, the end time of the training period after “4 months” selected in Step S306 ( For example, 9/30) is set. In the same manner, the worker staff assignment unit 1113 also selects “3” selected in step S306 from the start time at which the delivery deadline of “process 3” occurs for “worker C”. Monthly training period is set.

Thereafter, the worker staff assignment unit 1113 sets the worker training plan information shown in FIG. 10 for the training period set in step S308 and outputs it (S309). Then, the worker personnel assignment unit 1113 repeats the processing step S307 as many times as the number of all workers whose training period has been selected (S310), and further, the processing step S305 as many times as the number of all processes in order to plan the target product. Steps S304 to S311 are repeated (S311), and the processing steps S304 to S311 are repeated for the number of all the steps in order to plan all target products (S312). When the process of step S312 is finished, all the processes shown in FIG. 14 are finished.

FIG. 15 is a flowchart showing a process of performing a production simulation from the present to the future with a plurality of work plans in step S40 in FIG. 12, and evaluating whether the delivery date of each product is in time.

First, the production simulation unit 1114 takes in the information stored in the storage unit 115 regarding the target product whose delivery date is delayed in step S20 (S401).

Next, the production simulation unit 1114 repeats the processing steps S403 to S409 based on the number of worker training plans calculated in S30 (S402), and further, the number of all target products that are delayed in delivery in step S20. The processing steps S304 to S308 are repeated (S403), and the processing steps S405 to S407 are repeated for the number of all the steps in order to make a plan for the target product (S404).

Then, the production simulation unit 1114 increases the operation time of the target product and the target process by unit time (S405). Next, the production simulation unit 1114 executes production simulation (S406). Since this step S406 is the same process as the process for detecting the delivery delay shown in step S20 shown in FIG. 12, for example, the description thereof is omitted here.

After that, the production simulation unit 1114 confirms that the delivery date delay has been resolved, and if the delivery date delay has been resolved, proceeds to step S409, and if the delivery date delay has not been resolved, proceeds to step S408 (S407). If the delivery delay has not been resolved, the production simulation unit 1114 repeats the processing steps S405 to S407 by the number of all the steps in order to make a plan for the target product (S408), and proceeds to step S409.

When step S407 or S408 is completed, the production simulation unit 1114 repeats the processing steps S404 to S408 as many times as the number of all processes in order to plan all the target products (S409), and all the worker training plans Then, the processing steps S403 to S409 are repeated (S410). When the process of step S410 ends, all the processes shown in FIG. 15 end.

Finally, the output result in step S50 shown in FIG. 12 will be described. When each process up to step S40 described above is performed, the output unit 113 outputs the worker training plan shown in FIG. 10 or the simulation result of the work plan changed according to the worker training plan (S50).

FIG. 16A is a schematic diagram illustrating an example of an output screen 1000A output by the output unit 113. As shown in FIG. 16A, the output screen 1000A output by the output unit 113 displays the worker training plan shown in FIG. 10 on the left side of the screen and the simulation result on the right side of the screen. In the worker training plan, the start time when the training period elapses and the worker can apply to mass production of the product is set (for example, in the case of worker C, the training period is up to 6/30, so the application start is started. Time 7/1 is set). In addition, the simulation result has the compliance rate of the delivery date designated by the customer as the vertical axis, and the work plan pattern (Case 1 to Case 3) after the worker training executed in each process described above as the horizontal axis. . In the example shown in FIG. 16A, the Case 1 and Case 3 patterns exceed the delivery date T specified by the customer, and therefore the Case 2 pattern work plan is adopted.

In addition, when there are a plurality of patterns satisfying the delivery date from the customer, an effective pattern having the shortest delivery date may be adopted from these. Further, threshold values of production management indicators such as a delivery date compliance rate and a production amount that indicate a proportion of compliance with the delivery date of the product are stored in the storage unit 115 in advance, and the most appropriate one that satisfies these threshold values (for example, production) It is also possible to adopt the one having the largest amount or the one having the most efficient arrangement of the worker). In this case, the threshold value and the simulation result may be displayed in association with each other, and it may be possible to determine how efficient the threshold is.

As described above, if the production index such as the production volume and the delivery date compliance rate deteriorates due to the lack of skills of the workers due to the above-described processes, the work of the product is considered after considering the worker's training plan. It is possible to create a plan. For example, if production indicators such as production volume and delivery date compliance deteriorate due to lack of skills of workers, it is presented together with a quantitative estimate of how much the production indicators will deteriorate, It becomes possible to support the creation of a work plan including an arrangement plan.

As shown in FIG. 16B, the output unit 113 displays, for example, the worker-specific training information shown in FIG. 8 and the process-specific training information shown in FIG. 9 on the screen 1000B, and the input unit 112 receives the information from the user. It is also possible to accept designation and input of these items. In the example shown in FIG. 16B, the standard period and the actual period of the worker-specific training information shown in FIG. 8 are compared, the result obtained as the learning time is displayed, and the process-specific training information shown in FIG. Among these, the screen when each item other than the education item is displayed is shown. The values of these items can be edited by pressing the illustrated edit button or the like.
