Description

  The present invention relates to a work distribution device, a work distribution method, a work distribution program, and a recording medium storing a work distribution program for the worker to perform work with high production efficiency based on the result of measuring the work time of the worker at the production site. About. In particular, the assembly work that overflows from the direct workers who are placed in each process of the production line that produces products and assembles the products, and other direct workers who have spare capacity and / or line management, transportation, and parts supply work. The present invention relates to a work distribution device, a work distribution method, a work distribution program, and a recording medium storing a work distribution program, which are interpolated by an indirect worker to perform a production plan.

  Conventionally, in order to improve work efficiency by appropriately allocating multiple operations to workers at production sites, team leaders and other supervisors are appropriate to meet the process based on empirical rules. A work plan and work time were set and a production plan was created.

In addition, in the work distribution table creation support system of Patent Document 1, a plurality of types of products to be assembled from the production plan and personnel plan are sequentially mixed and flowed on the same assembly line, and each is arranged along the assembly line. It is assumed that the workers will assemble the products by sequentially performing the element work within the set cycle time, and for each type of product to be assembled, the arrangement and number of each worker and the element work performed by each worker Create a work analysis table that pre-determines the procedure, standard element time, and standard process that integrates the standard element time, and on the other hand, the production quantity ratio of product types mixed from the production plan and the process time by type Create a weighted average distribution table multiplied by the weighted average data of the weighted average distribution table, find the weighted average cycle time of each process corresponding to each product type, and The total cycle time obtained by integrating these is set to be within the set cycle time.
JP 2002-215860 A (refer to pages 3 to 4, pages 6 to 7, and FIG. 13)

  In the system of Patent Document 1, when the result of work distribution exceeds the set cycle time, the ratio of the products to be mixed is changed or the work is allocated to the workers in the preceding and following processes within the set cycle time. Although the solution has been solved so that the production efficiency can be maximized, there is a case where the work distribution by only the workers in the preceding and following processes cannot be performed within the set cycle time while pursuing the maximum production efficiency.

  As a solution in such a case, measures such as adding workers, reducing the planned number of the day and adjusting according to the monthly plan, or imposing overtime on workers are implemented.

  However, these methods involve a change in production conditions and thus have a problem of affecting the financial burden.

  In general, there are worker divisions at production sites, and direct workers who directly work on products in the process, and indirect to production such as line management, transportation, and parts supply. There are two workers who carry out the work. The direct operator's work is continuous, so there is little free time. On the other hand, the work of indirect workers tends to occur mainly intermittently. For this reason, idle time occurs between indirect work, and when this idle time is viewed as the total time of the day, Actually, the time itself is a great loss time.

  Conventionally, this idle time has been used for the next day's production preparations and 5S activities (organization, cleaning, etc.), but these utilization methods are efforts to increase productivity through quality improvement, etc. Since it is not a work that contributes to achievement, it could not be an improvement measure that directly leads to an increase in production efficiency.

  Therefore, the present invention has been proposed to solve such problems, and the assembly work overflowing from the direct workers arranged in each process of the production line for producing the product is replaced with another direct worker who has power. Another object of the present invention is to provide a work distribution apparatus, a work distribution method, a work distribution program, and a recording medium storing the work distribution program that allow an indirect worker to interpolate and achieve a production plan.

  The work distribution apparatus according to the present invention is configured to perform assembly work overflowing from a direct worker who assembles a product for each process of a production line for producing a product with other direct workers who have power and / or line management, transportation, and parts. A work distribution device that interpolates an indirect worker who performs a supply work to achieve a production plan, and for each type of product, the direct worker and the indirect worker in each process of the production line that produces the product Basic production information including the work time database that stores the cycle time, which is the time required for each worker to assemble one product, the type of product to be produced, the number of products planned for production, and the working hours of the worker For each process of a production line that produces a product based on the basic production information input to the input device and stored in the work time database. Based on the cycle time for each product process and worker, select the worker who should be a direct worker for the process, and further, based on the cycle time of each selected worker, It is determined whether or not the plan can be achieved by assembling the products for the planned number of production within the working hours. If there is a process that is determined to be unable to achieve the plan, from the direct operator of the process that cannot achieve the plan An arithmetic unit that calculates a work distribution for interpolating an overflowing assembly work by a direct worker in another process capable of completing the assembly work in a shorter time than the working time, and a work distribution for interpolating by an indirect worker. I have.

  In this way, if the production plan cannot be achieved within working hours even if the optimal direct workers are allocated to each process and the work is allocated, the direct work of the process that cannot achieve the production plan Since the assembly work overflowing from the worker can be interpolated not only by the direct worker of other processes that can complete the assembly work in a shorter time than the working hours, but also by the indirect worker, the conventional problem Change the production conditions such as “increase the number of workers”, “adjust the number of units produced on the day and adjust the number of units produced on a monthly basis”, and “impose overtime to achieve the planned number” The daily production plan can be achieved.

  Further, the loss time between the indirect work that has occurred in the indirect worker is devoted to the interpolation of the direct work, so the loss time is reduced.

  Furthermore, the work distribution device of the present invention may further include an output device that outputs a work interpolation instruction based on the work distribution result obtained by the arithmetic device.

  Thus, each worker can accurately grasp in what process what time should be directly interpolated.

  The work distribution method according to the present invention allows assembly work overflowing from a direct worker who assembles a product for each process of a production line to produce a product to another direct worker who has power and / or line management, transportation, and parts. A work allocation method in which an indirect worker who performs supply work interpolates to achieve a production plan. Basic production information including the type of product to be produced, the number of production plans for that product, and the working hours of the worker is input. Then, for each process of the production line that produces the product based on the basic production information, select the worker who should be the direct worker in the process based on the cycle time of each product process and worker. Based on the cycle time of each worker selected in this step, and after assembling the products for the planned number of production within the working hours in each process If there is a step for determining whether or not the plan can be achieved and a process for which it is determined that the plan cannot be achieved in this step, the assembly work overflowing from the direct worker of the process that cannot achieve the plan is made more than the working hours. When there is a step to determine the work distribution to be interpolated by the direct worker of another process that can complete the assembly work in a short time, and a process that is determined to be unable to achieve the plan even by the work distribution determined by this step And a step of obtaining a work distribution for causing an indirect worker to interpolate an assembly work overflowing from a direct worker in a process that cannot achieve the plan.

  According to the work distribution method having such a configuration, the method further includes a step of outputting a work interpolation instruction based on the work distribution result, so that an accurate interpolation work instruction is issued to each direct worker and indirect worker. May be.

  The computer-readable recording medium of the present invention stores a screw tightening worker arrangement program for realizing the above-described work distribution method.

  The assembly work overflowing from the direct workers who assemble the products for each process of the production line that produces the product is transferred to other direct workers who have sufficient capacity and / or indirect workers who perform line management, transportation, and parts supply work. By performing the interpolation, it is possible to reduce the loss time that has occurred in the indirect worker, and it is possible to realize the number of production (production efficiency) that cannot be achieved by the direct worker alone.

  Therefore, production such as “increase the number of workers” or “adjust the production volume in the month by reducing the planned number of the day”, or “impose overtime to achieve the planned number”, which was the problem of the conventional method Without changing the conditions, it is possible to reduce the loss time and obtain the work distribution to achieve the production plan.

  Embodiments of the present invention will be described below with reference to the drawings.

  FIG. 1 is a functional configuration diagram according to an embodiment of the work distribution apparatus of the present invention.

  This work distribution device is roughly composed of a storage device 21, an input device 22, a calculation device 23, an output device 24, and a control device 25.

  The storage device 21 stores production basic information including the type of product to be produced (hereinafter referred to as a model), the planned number of units, and working hours input to the input device 22 and the calculation result in the arithmetic device 23. A main storage device 21a and a work time database 21b that stores a cycle time, which is a time required for each worker to assemble one product in each process of the production line for producing a product of that model for each model, are provided. Yes.

  The main storage device 21a includes areas of a processing number table (see FIG. 8), a direct worker interpolation calculation table (see FIG. 9), and an indirect worker interpolation calculation table (see FIGS. 10 and 11). In each item of the table, basic production information including information on the model, the number of planned units and working hours input to the input device 22 and a calculation result in the arithmetic device 23 are stored.

  As shown in FIGS. 8 to 10, all of the above tables are model name, planned number, working hours, process name, worker name, cycle time, capacity factor, allocation range time indicating time range for performing work distribution, It consists of each item of the time-unit matrix that shows the number of products assembled by each worker in the time series. Further, as shown in FIGS. 8 to 10, the worker name area stores information on the worker classification (direct or indirect) and the work classification (in charge or interpolation), as shown in FIGS. 8 to 10.

  FIG. 7 shows an example of the stored contents stored in the work time database. The work time database 21b stores work time data for each model. This work time data consists of model name, process name, worker name, and time (minutes) (cycle time) required for the worker to assemble one product in the process, and the cycle time is stored for each worker by process. Has been. For example, the working time data of the product of model name GG03 shown in FIG. 7 includes three process names of process A, process B, and process C constituting the product production line, and each of these three processes. The cycle time of the worker is recorded. Therefore, from the work time data shown in FIG. 7, the cycle time of each worker in each process can be read. For example, for process A, the first cycle time is 1.06 minutes, the second cycle time is 1.10 minutes, It can be seen that the cycle time of the cocoon is 1.22 minutes and the cycle time of the Ding is 1.33 minutes.

  The input device 22 receives basic production information including a production model, a planned number, and working hours.

  FIG. 6 shows an example of a basic production information input screen displayed on the input device 22. As shown in FIG. 6, on this basic production information input screen, it is possible to input or select information on the model name (production model), planned number of units, and working hours of a product to be produced. In the production basic information input screen shown in FIG. 6, the production model GG03, the planned number of 450 units, and the working time 480 minutes are entered.

  The computing device 23 sets the cycle time for each process and each worker stored in the work time database for each process of the production line that produces the product based on the basic production information input to the input device 22. Based on the cycle time of each worker selected by the worker selection unit 23a that selects a worker who should be a direct worker for the process based on the worker selection unit 23a, within the working hours The number of products to be assembled (hereinafter referred to as the number of processed units) is calculated according to the time series, and from this number of processed units, the planned number of products can be assembled within the working hours for each of the processes, and the plan can be achieved. The number-of-processes calculation unit 23b that determines whether or not the assembly work overflows from the direct operator in the process that is determined to be unable to achieve the plan by the number-of-processes calculation unit 23b A work interpolation calculation unit 23c for obtaining a work distribution to be interpolated by the direct worker and a work distribution to be interpolated by an indirect worker in another process capable of completing the assembly work in a shorter time than the working hours, A work interpolation calculation unit 23d that outputs a work interpolation instruction to a direct worker or an indirect worker to the output device 24 based on the work distribution result obtained by the work interpolation calculation unit 23c.

  The output device 24 outputs a work interpolation instruction to a direct worker and an indirect worker based on information stored in the main storage device 21a according to a command from the interpolation instruction unit 23d in the arithmetic device 23.

  The control device 25 controls the storage device 21, the input device 22, the arithmetic device 23, and the output device 24. Specifically, based on the work time measurement result, the work time data regarding each model in the work time database 21b in the storage device 21 is updated, the screen control of the input device 23 and the output device 24 is performed, the storage device 21 stores the time block for instructing work interpolation, the timing of the transport work performed by the indirect operator, and the time required for the transport work in the main storage device 21a. You are doing calculations.

  FIG. 5 shows an example of a work model that can be used to distribute work using the work distribution apparatus having the above configuration.

  Each process of the work model shown in FIG. 5 is a process in which a single worker, which is generally called “one person completion type” or “job shop process”, completes a series of work in one process. The work process is composed of three work processes 41, 42, and 43 including process A, process B, and process C.

  In each process, direct workers 41a, 42a, and 43a for assembling products are arranged, and in addition to direct workers 41a, 42a, and 43a, indirect operations such as line management, transportation, and parts supply are performed. An indirect worker 44 who is in charge is arranged. As a process form, since each process is not connected with a conveyor etc., and each process is installed independently, in order to take over to a post process, the conveyance operation | work between processes generate | occur | produces.

  Each direct worker periodically repeats the same work on the product in each process, and when one work is completed, each direct worker is installed next to the work table on which the work is performed. The product shall be placed on a transport cart. At this time, it is assumed that the number of products to be loaded per cart is specified, and here, 20 products can be loaded per cart. In addition, direct workers shall be engaged in direct work in each process and will not carry out any transportation work.

  The indirect worker carries out the transportation work that occurs between these three processes at the timing when the transportation carts installed in each direct worker are full (for 20 vehicles in this case). It is assumed that a specified time is required for each transporting operation that occurs between processes, and two minutes are required for each transporting operation.

  A method of actually allocating the assembly work of the products assembled in such a work process using the work distribution device having the above configuration will be described with reference to the flowchart shown in FIG.

  First, in step S101, the operator inputs the production model, planned number, and working hours, which are basic production information, from the basic production information input screen shown in FIG.

  Thus, the main storage device 21a stores the input basic production information, and the required level cycle time and the required level capacity coefficient calculated from the input planned number and working hours. The required level cycle time is the cycle time required to achieve the planned number of vehicles, and is obtained by dividing the working hours by the planned number of vehicles. The required level capacity coefficient is the number of units produced per minute required to achieve the planned number, and is obtained by the reciprocal of the required level cycle time.

  Therefore, in the input example of the basic production information shown in FIG. 6, information on the model name GG03, the planned number of 450 units, and the working time of 480 minutes is recorded in the processing number table in the main storage device 21a (see FIG. 8). . Furthermore, as the necessary levels necessary to achieve the planned number of units, the required level cycle time 480 (working hours) ÷ 450 (planned number of units) = 1.07, and the capacity coefficient 1 / 1.07 = 0.94 units / min. Is calculated and recorded in the processing number table (see FIG. 8).

  In step S102, the worker selection unit 23a is based on the work time data (see FIG. 7) stored in the work time database 21b for each process of the production line that produces the model stored in the main storage device 21a. The worker who should be the direct worker for the process is selected.

  The name, cycle time, and capability coefficient of each worker selected in each step in step S102 are recorded in the processing number table in the main storage device 21a (see FIG. 8).

  Note that the worker who should be a direct worker for each process is the worker with the fastest cycle time in the process, and according to the work time data of the model GG03 shown in FIG. A is selected as the operator, and B is selected as the direct worker in charge of the process B, and 丙 is selected as the direct worker in charge of the process C. , Capacity factor 0.94 units / min, B for process B, cycle time 0.98, capability coefficient 1.02 units / min, for process C, cycle time 1.35, capacity factor 0.74 units / min Various types of information are recorded (see FIG. 8).

  At this time, the working hours input as the allocation range time are stored in the main storage device 21a. For example, when a working time of 480 minutes is input, an allocation range time of 0 <X ≦ 480 is recorded in each process of the processing number table in the sense of a range of 0 minutes or more and 480 minutes or less (see FIG. 8).

  Subsequently, in step S103, the processing number calculation unit 23b calculates the number of products assembled in the allocation range time (hereinafter referred to as the processing number) for each process along the time series, and further calculates the calculated allocation range. The excess or deficiency in each process is calculated by subtracting the planned number from the number of treated workers at the end point (end of working hours).

  As shown in FIG. 8, the calculation result of the processed number is recorded in the time-number matrix in the processed number table in a time series of 1 minute intervals within the allocation range time. The number of treatments is obtained by multiplying the capacity factor of each direct worker in each process by the elapsed time (minutes) from the start of the treatment. In addition, the number of processed units necessary to achieve the production plan is calculated in the same manner and recorded as a necessary level in the time-unit matrix of the processed unit table (see FIG. 8).

  In addition, the excess / deficiency results in each process are recorded in the number-of-processes table of the main storage device 21a (see FIG. 8). In the processing number table shown in FIG. 8, it is possible to assemble 452.8 products within the allocation range time (within working hours) against the planned number of 450 units. △ (Correct) 3 units, Process B is able to assemble 489.8 products within the allocation range time (working hours). No. deficiency has been recorded, and only 356 units can be assembled within the allocation range time (working hours), and over / deficiency is 94 (negative) 94 units.

  Subsequently, in step S104, based on the excess / deficiency result calculated in step S103, it is determined whether or not the production plan can be achieved by assembling the products for the planned number for each process within the working hours.

  When the excess / deficiency result is Δ (positive) in all the steps, OK is determined, and it is determined that the production plan can be achieved by only the current direct worker, and all the processes are ended. If one or more excess / deficiency results are ▲ (negative), NG is determined, and the process proceeds to step S105 to continue the work distribution process.

  According to the excess / deficiency result shown in the processing number table of FIG. 8, since the excess / deficiency result in process C is ▲ (negative), NG is determined, and the process proceeds to step S105 to continue the work distribution process. .

  In step S105, the arithmetic unit 23 updates the allocation range time stored in the main storage device 21a.

  The allocation range time refers to a time block for instructing work interpolation. The working time is divided into several time blocks from the start to the end of work, work is distributed for each time block, and a work interpolation instruction is output. For example, if the time block of the allocation range time is set every 60 minutes, in the first loop, 60 minutes from the start (0 <X ≦ 60), and from the second time onward, 60 minutes to 120 minutes (60 < X ≦ 120), the allocation range time is updated from 120 minutes to 180 minutes (120 <X ≦ 180), and each time the allocation range time is updated, the work distribution is calculated and a work interpolation instruction is output. Therefore, the steps (S105 to S110) from the allocation range time update to the output of the work interpolation instruction are repeated until the allocation range time reaches the working hours recorded in step S102. Further, as described above, the working time input in step S102 is stored as the initial value of the allocation range time.

  In addition, for the time block of the allocation range time, it is considered that the unit of 60 minutes or 20 minutes is standard, but depending on the cycle time of the product, a short span such as 15 minutes, 120 minutes, 180 minutes, etc. A span time block is also conceivable.

  Subsequently, in step S106, the interpolating operation unit 23c performs an assembly work overflowing from the direct operator in the process in which the excess / deficiency result determined that the plan cannot be achieved in step S104 is ▲ (negative). The work interpolation calculation for obtaining the work distribution to be directly interpolated by the worker in the process of () is performed. The result of the interpolation calculation for the direct operator is recorded in the direct operator interpolation calculation table (see FIGS. 9A to 9B).

  Subsequently, in step S107, based on the interpolation calculation result for the direct operator in step S106 (see FIG. 9B), the plan can be achieved in the process in which the excess / deficiency result is ▲ (negative) in step S104. Judge whether or not. If the plan can be achieved, OK is determined, and the process proceeds to step S109. If the plan cannot be achieved, NG is determined, and the process proceeds to step S108.

  The determination as to whether or not the plan can be achieved is made with reference to the direct operator interpolation calculation table (see FIG. 9B) in which the interpolation calculation result of step S106 is recorded. If there is a process, it is judged that the plan cannot be achieved. For example, in the direct operator interpolation calculation table of FIG. 9B, there are 56.3 units to be processed within the allocation range time to achieve the plan (hereinafter referred to as a target number), whereas the process C The total number of direct workers who are responsible for the work in the process and the number of direct workers who interpolate the work in process C (hereinafter referred to as the total number) is 47.1 units at the end of the allocation range. Since the number is ▲ (negative) 9.2, an NG determination is made, and the process proceeds to step S108.

  In step S108, the interpolating operation unit 23c performs work distribution for causing the indirect worker to further interpolate the assembly work overflowing from the direct worker in the process of ▲ (negative) where it is determined that the plan cannot be achieved in step S107. At the same time as performing the required work interpolation calculation, a work interpolation instruction (see FIG. 13) is created based on the calculation result.

  While recording in the indirect worker interpolation calculation table (see FIGS. 10A to 10B and FIGS. 11A to 11B) based on the direct operator interpolation calculation table (FIG. 9B), An interpolation calculation is performed on the indirect worker, and a work interpolation instruction is created based on the indirect worker interpolation calculation table (FIG. 11B) in which the calculation result is recorded. The work interpolation instruction is stored in the main memory. It is stored in the device 21a.

  In step S109, the interpolation instruction unit 23d causes the output device 24 to directly display the work interpolation instruction to the worker and the work interpolation instruction to the indirect worker, and output the work interpolation instruction sheet stored in the main storage device 21a. (See FIG. 13).

  As for the work interpolation instruction, the direct worker interpolation instruction is displayed based on the direct worker interpolation calculation table (see FIG. 9B) in the main storage device 21a, and the indirect worker interpolation calculation table (see FIG. 9). 11 (B)), an interpolation instruction to the indirect worker is displayed.

  In subsequent step S110, the arithmetic unit 23 determines whether or not the allocation range time satisfies the working hours. If the allocation range time satisfies the working hours, a determination of YES is made and all processing is completed. If the allocation range time does not satisfy the working hours, a determination of NO is made, the process returns to step S105, the allocation range time is updated, and an interpolation operation is performed directly on the worker within the allocation range time (step S106). To the interpolation instruction output (step S109) are sequentially started.

  For example, the allocation range time stored in the indirect operator interpolation calculation table shown in FIG. 11B is 0 <X ≦ 60, and since the working time has not reached 480 minutes, it is fed back to S105. Thereafter, using the same method, the interpolation calculation processing (step S105 to step 109) is repeated for 60 minutes to 120 minutes, 120 minutes to 180 minutes, and finally the processing is 420 to 480 minutes. When the allocation range time is 420 <X ≦ 480, that is, 420 to 480 minutes, that is, when the end time of the allocation range time reaches the working time 480 minutes, the interpolation calculation processing (steps S105 to S109) in the allocation range time is performed. After the end, all the processes are ended.

  Next, according to the flowchart of FIG. 3, the work interpolation calculation method for the direct worker in step S106 shown in the flowchart of FIG. 2 will be described in detail.

  First, in step S201, the number of processes in each process within the allocation range time is calculated, and the calculation result is recorded in the time-number matrix of the operator interpolation calculation table (see FIG. 9A) in time series. To do.

  For the model name, planned number of units, working hours, worker in each process, worker cycle time in each process, and worker capacity factor in each process of the direct operator interpolation calculation table (see FIG. 9A), The same contents as the contents of the processing number table (see FIG. 8) are recorded (see FIG. 9A). The value updated in step S105 is recorded in the allocation range time (see FIG. 9A). The number of processes in each process within the allocated range time is calculated based on the cycle time of the direct worker in each process, and the calculation result is recorded in the time-number matrix in the direct operator interpolation calculation table (FIG. 9). (See (A)). The number of processed units is obtained by adding the value obtained by multiplying the number of processed units at the start of the allocation range time to the elapsed time (minutes) from the start of the allocation range time by the capacity coefficient.

  Also, as for excess and deficiency in each process, a value obtained by subtracting the target number from the number of processes at the end of the allocation range time in each process is calculated and recorded directly in the operator interpolation calculation table (see FIG. 9A). .

  Subsequently, in step S202, the time-number of direct workers in the process in which the excess / deficiency result is Δ (positive) in the direct worker interpolation calculation table (FIG. 9A) in which various data is recorded in step S201. The matrix is scanned to extract the time (timing) for achieving the target number. The direct worker who can extract this time can use the remaining work time in the allocation range time for interpolation of the assembly work overflowing from the direct worker in another process.

  Subsequently, in step S203, among the direct workers who have been able to extract the time to achieve the target number in step S202, the direct worker who achieves the target number of the own process earliest is selected.

  Subsequently, in step S204, the direct worker selected in step S203 is assigned as an interpolation worker in the process where the excess / deficiency result is ▲ (negative), and the number of processing performed by the assigned direct worker as the interpolation worker is determined. It is calculated and recorded directly on the time-number matrix in the operator interpolation calculation table (see FIG. 9B). Note that the time zone in which the direct worker selected in step S203 is assigned as an interpolation worker to a process with an excess / deficiency result of ▲ (negative) is assigned from the time at which the direct worker achieves the target number of own process. Until the end of time.

  When assigning, the cycle time in the interpolation target process of the direct worker selected in step S203 (the process in which the excess / deficiency result is ▲ (negative)) is obtained from the work time database (see FIG. 7), and directly Record the name of the direct operator, the acquired cycle time and the ability coefficient calculated from the cycle time in the area of the interpolation target process in the operator interpolation calculation table (see FIG. 9B), and further Based on the capacity factor, calculate the number of interpolated operations performed in the interpolation target process between the time when the direct worker achieves the target number of the process and the end of the allocation range time, and the calculation result is calculated as time- Record in the number matrix. Further, the total number in the interpolation target process is calculated and recorded as a total directly in the number-time matrix in the operator interpolation calculation table. (See FIG. 9B).

  For example, according to the time-unit matrix of the direct operator interpolation calculation table shown in FIG. 9A, the process of processing 57.1 units at the time of 56 minutes with respect to the target number of 56.3 units in the allocation range time. B's direct worker B achieves the target number in the process first, and the excess or deficiency is selected as the interpolation operator for the process of ▲ (negative). Therefore, the interpolation work of the process C is assigned to the second party from 56 minutes when the target number is achieved in the own process to the allocation range time 60 minutes. The name of the second party, the cycle time in the second process C, the capacity factor in the second process C, and the number of processes performed by the second process in the process C from 56 minutes to 60 minutes are directly recorded in the operator interpolation calculation table. (See FIG. 9B). Further, the total number of units in the process C and the excess or deficiency at the end of the allocation range time are calculated and recorded directly in the operator interpolation calculation table (see FIG. 9B).

  According to the direct operator interpolation calculation table of FIG. 9B in which the result of the direct interpolation calculation performed on the workers in this way is reflected, the total number of processes C is 56.3 units at the target number. This is 47.1 units, which is still a result of a shortage of 9.2 units against the target number. Therefore, NG is determined in step S107, the process proceeds to step S108, and the interpolation calculation process for the indirect worker is performed (see FIG. 2).

  Next, the work interpolation calculation method for the indirect worker performed in step S108 of the flowchart shown in FIG. 2 will be described in detail according to the flowchart of FIG.

  In step S301, the worker selection unit 23a selects a worker who is an indirect worker from the work time database 21b in the storage device 21, and the indirect work in the main storage device 21a is determined based on the cycle time and capability coefficient of the worker. Stored in the user interpolation calculation table (see FIG. 10A).

  As the indirect worker, a worker who is not selected as a direct worker is selected. Among the workers indicated by the work time data in FIG. 7, the worker is not a direct worker, that is, a worker who is not stored as a direct worker in the direct worker interpolation calculation table shown in FIG. 9B. Ding is selected as an indirect worker. Therefore, as an indirect worker who performs the interpolation work of the process C in which the excess / deficiency result is ▲ (negative) in the direct worker interpolation calculation table of FIG. 9B, the worker from the work time database (see FIG. 7). The cycle time 1.67 in the process C of Ding is extracted and stored in the indirect operator interpolation calculation table. Further, the capacity coefficient 1 / 1.67 = 0.60 units / minute is calculated from the cycle time 1.67. It is stored in the indirect operator interpolation calculation table (see FIG. 10A). The indirect worker interpolation calculation table (see FIG. 10A) stores in advance the contents of the direct worker interpolation calculation table (see FIG. 9B) (interpolation calculation results for direct workers). Yes.

  Subsequently, in step S302, the interpolation calculation unit 23c calculates the number of processed persons within the indirect worker allocation range time from the capacity factor of the indirect worker in the indirect worker interpolation calculation table created in step S301, and the calculation result Is recorded in the time-number matrix in the indirect operator interpolation calculation table (see FIG. 10A).

  Subsequently, in step S303, the interpolation calculation unit 23c scans the time-number matrix (see FIG. 10A) in the indirect worker interpolation calculation table recorded in step S302, and directly in the interpolation calculation for the direct worker. The time in the direct operator interpolation calculation table that could not be interpolated by the worker—the time at which the indirect worker finishes processing the shortage (see FIG. 9B) on the number matrix is extracted, and after that extracted time The time-number matrix of the indirect worker interpolation calculation table is recorded again so that the indirect worker is not assigned the interpolation work (see FIG. 10B).

  For example, the number of shortages in the process C indicated by the direct operator interpolation calculation table in FIG. 9B is 9.2. Referring to the time-number matrix shown in FIG. 10A created in step S302, the time required for the indirect operator who performs the interpolation work in step C to process the insufficient number of 9.2 units is 9.58. It can be seen that it is 16 minutes to finish processing the table. Therefore, the indirect worker interpolation operation table is completed in 16 minutes, and the number of indirect workers processed in process C in the indirect worker interpolation calculation table is not increased as it is 9.58 after 16 minutes. Re-record the time-unit matrix (see FIG. 10B).

  Subsequently, in step S304, the total number of processing of the direct worker (person in charge), direct worker (interpolation worker), and indirect worker (interpolation worker) in the interpolation target process is calculated. 11 (A), the total is recorded in the time-number matrix in the indirect operator interpolation calculation table.

  Subsequently, in step S305, in the time-number matrix of the indirect worker interpolation calculation table (see FIG. 11A) created in step S304, the occurrence time of the transport work that is the work in charge of the indirect worker is extracted. The number of processed units and the total number of units are recalculated except for the extracted time period of transport work, and the calculation result is recorded in the time-unit matrix (see FIG. 11B).

  In the work model shown in FIG. 5, as described above, the number of carrying trolleys for carrying work is defined as 20 so that each time a worker directly handles 20 cars in each process, the work model is carried. Work time will occur. Therefore, the time-number matrix (see FIG. 11A) in the indirect operator interpolation calculation table created in step S304 is scanned, and the number of processed units in each process is 20, 40,. Transportation work will occur in multiple times. In addition, since it is a time zone during which the interpolation work cannot be performed during the transportation work, the number of processed units does not increase with the passage of time in the time period of the transportation work.

  In the time-unit matrix in the indirect operator interpolation calculation table shown in FIG. 11 (A), the total number of units in process C is 15 minutes, 20 units in process B is 20 minutes, and 20 units in process A. The remaining 22 minutes and so on are extracted, and after this time, each 2 minutes is a time zone for the indirect worker's transportation work, and interpolation work cannot be performed. This result is reflected on the matrix, recalculated, and recorded in the time-number matrix as shown in FIG.

  As a result of the calculation in the above steps, the excess or deficiency of the process C is Δ (positive) 0.4 units, and the target number within the allocation range time has been achieved (see FIG. 11B).

  Subsequently, in step S306, the interpolation calculation unit 23c sets the number of processes A, the number of processes B, and the total number of processes C in the time-number matrix in the indirect operator interpolation calculation table shown in FIG. The calculation results are represented in a two-dimensional graph with the X axis and time on the Y axis, respectively, and a time-unit transition table 112 (see FIG. 13) is created. Remember.

  In step S307 simultaneously with step S306, the interpolation calculation unit 23c creates the post-interpolation timing table 113 (see FIG. 12) of the indirect worker indicating the work timing of the indirect worker, and the main storage device 21a creates the created interpolation. The rear timing table 113 is stored.

  Subsequently, in step S308, the interpolation calculation unit 23c uses the time-unit transition table 112 created in step S306 and the post-interpolation timing table created in step S307 (see FIG. 12), as shown in FIG. And the main storage device 21a stores the created work interpolation instruction. In addition, the work interpolation instruction 110 for the direct worker calculated in step S106 and the work interpolation instruction for the indirect worker calculated in step S305 are displayed on the upper part of the instruction sheet.

  FIG. 13 shows an example of an interpolation instruction document created based on the indirect worker interpolation calculation table shown in FIG. In this interpolation instruction, in addition to the time-number transition table 112 and the post-interpolation timing table 113 described above, the operation interpolation instruction 110 for the direct operator, “direct worker process B B 56 minutes to 60 minutes” The operation interpolation instruction 111 for the indirect worker, “Indirect worker, please refer to the following work timing and interpolate the process C” is displayed.

  As described above, the created work interpolation instruction is output to the output device 24 in step S109.
