Description

  The present invention relates to a scheduling device that performs scheduling of a plurality of types of work processes, and more particularly to a technique for performing scheduling in consideration of educational opportunities for field workers.

2. Description of the Related Art Conventionally, scheduling devices that schedule, for example, a plurality of types of work processes related to product production so as to satisfy work conditions such as a preset delivery date are known (see, for example, Patent Documents 1 and 2). According to the schedule created by such a scheduling device, production can be performed in compliance with the delivery date of the product. In particular, for example, Patent Document 2 discloses a technique for performing scheduling mainly for distributing a load by leveling a plurality of types of work processes.
By the way, at the production site, in order to improve the skill level of the worker, the skilled worker is educated to the unskilled worker. At this time, in order to effectively provide education for a certain work process, it is desirable to provide an opportunity for continuous education for a certain period of time for that work process.

However, in the conventional scheduling method, for example, leveling of a plurality of types of work processes is focused on, and scheduling that considers the opportunity for training of workers is not performed. Therefore, it is necessary to provide education in accordance with a schedule created so as to satisfy preset work conditions, and the educational opportunities for each work process are distributed. There was a problem that education was not possible.
Of course, it is possible to ignore the schedule and continuously execute a certain work process for the education of the worker, but in this case, there arises a problem that the product delivery date cannot be observed. In addition, in order to comply with the product delivery date, it may be possible to conduct education outside the schedule, but in this case, skilled and non-skilled workers will be forced to work outside the working hours. There is a problem.
Accordingly, the present invention has been made in view of the above circumstances, and an object of the present invention is to provide a scheduling device capable of scheduling a plurality of types of work processes in consideration of an educational opportunity for workers. It is in.

In order to achieve the above object, the present invention is applied to a scheduling device having scheduling means for scheduling a plurality of types of work processes so as to satisfy a preset work condition including at least a delivery date, An education execution item setting means for setting an education execution item including at least a continuous operation time for continuously executing the operation process in order to educate a worker about any one or more of the operation processes, Scheduling means performs scheduling so as to provide the continuous work time for educating a worker for any one or a plurality of the work steps based on the training execution items within a range in which the work conditions can be satisfied. It is constituted as a scheduling device characterized by being a thing.
According to the present invention, when there is a margin in the work condition, it is possible to improve the efficiency of education of workers by intentionally providing the continuous work time as an educational opportunity within the range of the margin. That is, the present invention focuses on providing educational opportunities within a range where the work conditions can be satisfied, rather than focusing on leveling a plurality of types of work processes.
Furthermore, if the priority of education for each of the work processes is included in the education execution item, for example, it is possible to preferentially provide education opportunities for the work processes with high priority.

As a specific configuration of the present invention, the scheduling means is created by a temporary schedule creating means for creating a temporary schedule by scheduling each work process so that the work conditions are satisfied, and the temporary schedule creating means. In addition, a schedule update unit that rearranges the execution order of each of the work steps in the temporary schedule based on the education execution item, and whether or not the temporary schedule after being changed by the schedule update unit satisfies the work condition. It is conceivable to include a work condition satisfaction determining means for determining. Then, the scheduling means validates the rearrangement by the schedule update means on condition that the work condition is satisfied by the work condition satisfaction determination means.
According to such a configuration, it is possible to perform scheduling of each of the work processes in consideration of the education execution items while satisfying at least the work conditions.
It is also conceivable that the scheduling means performs scheduling so as to provide the continuous work time step by step in a preset order for each work process. Thereby, for example, it is possible to perform scheduling so that an operator with a low skill level is not trained on a work process with a high degree of difficulty or a risk.

According to the present invention, when there is a margin in the work condition, it is possible to improve the efficiency of education of workers by intentionally providing the continuous work time as an educational opportunity within the range of the margin. That is, the present invention focuses on providing educational opportunities within a range where the work conditions can be satisfied, rather than focusing on leveling a plurality of types of work processes.
In addition, if the education execution item includes the priority of education for each of the work processes, for example, it is possible to preferentially provide an educational opportunity for the work process with a high priority.
Furthermore, if scheduling is performed so as to provide the continuous work time step by step in a preset order for each of the work processes, for example, a work process with a high degree of difficulty and risk for a worker with a low skill level. Scheduling can be performed so that no education is provided.

As shown in FIG. 1, at the work site exemplified in the present embodiment, the coil received on the coil arrival is moved to the belt conveyor by the crane and conveyed to the work site by the belt conveyor. Then, the coil is packed by an operator at the work place, and the coil after the packing is conveyed by a belt conveyor. The coil conveyed by the belt conveyor is moved to a coil shipping place by a crane.
Here, it is assumed that a plurality of types of packing methods P1 to P3 (an example of a plurality of types of work processes) exist in the coil packing method performed by the worker in the workplace. And an operator packs a coil by the packing method set by the predetermined schedule among the said packing methods P1-P3. Further, the packing methods P1 to P3 differ in time required for work due to differences in the packing methods. Hereinafter, it is assumed that work times corresponding to the packing methods P1 to P3 are K1 to K3.

Next, a schematic configuration of the scheduling apparatus X according to the embodiment of the present invention will be described with reference to FIG.

A storage unit 2, an operation unit 3 including a keyboard for performing operations for setting educational execution items to be described later, a liquid crystal display that displays and outputs various types of information, and a printer that prints and outputs various types of information are included. The output unit 4 is schematically configured. The scheduling device X is an information processing device such as a personal computer. The storage unit 2, the operation unit 3, the output unit 4, and the like are provided in an external device different from the scheduling device X as long as communication with the control unit 1 is possible. May be.
The control unit 1 includes an education execution item setting function 10 (an example of an education execution item setting unit), a temporary schedule creation function 11 (an example of a temporary schedule creation unit), a work start time calculation function 12, a work end time calculation function 13, Various functions such as a work condition satisfaction determination function 14 (an example of a work condition satisfaction determination unit), a schedule update function 15 (an example of a schedule update unit), and an education execution item satisfaction determination function 16 (an example of an education execution item satisfaction determination unit) have.
These functions are implemented when the control unit 1 executes a scheduling process (see the flowchart of FIG. 4) described later according to a predetermined control program stored in the ROM by the CPU. Will be described in detail later. Each function may be configured by hardware such as an electric circuit.

In the scheduling apparatus X, the control unit 1 executes a scheduling process for rearranging a plurality of types of work processes included in the production schedule transmitted from the host computer Y so as to satisfy preset work conditions. Is done. The production schedule transmitted from the host computer Y is stored in the storage unit 2. In the host computer Y, the production schedule is set in advance by a user operation. Of course, the production schedule may be set by the scheduling device X.
Here, an example of the production schedule stored in the host computer Y will be described with reference to FIG.
As shown in FIG. 3, in the production schedule, for each of the coil numbers A1 to A10, packing is performed by any of the arrival times B1 to B10, the shipping times C1 to C10 (an example of delivery date), and the packing methods P1 to P3. The work conditions such as whether to perform are set. Here, the coil numbers A1 to A10 indicate lot numbers assigned to a plurality of coils.
The arrival times B1 to B10 indicate times when the coils of the coil numbers A1 to A10 are carried into the coil arrival place shown in FIG. 1, and the arrival times B1 to B10 are earlier in that order. The shipping times C1 to C10 indicate the time when the coils having the coil numbers A1 to A10 are shipped, that is, the time when the coils should be delivered to the coil shipping place shown in FIG. Assume that the times C1 to C10 are earlier in that order.
In the following, the scheduling process executed in the scheduling device X will be described by taking the case where the production schedule shown in FIG. 3 is set as an example.

First, the outline of the scheduling process executed by the control unit 1 in the scheduling device X will be described with reference to the flowchart of FIG. In the figure, S1, S2,... Represent processing procedure (step) numbers. Here, the control unit 1 when executing the scheduling process corresponds to a scheduling means.
As shown in FIG. 4, the control unit 1 includes an education execution item setting process (step S1) for setting an education execution item, a temporary schedule creation process (step S2) for creating a temporary schedule, and each work process. Start time calculation process (step S3) for calculating the time to start the work, work end time calculation process (step S4) for calculating the work end time of each work process, the provisional schedule defines the work conditions. Work condition satisfaction determination process for determining whether or not it is satisfied (step S5), schedule update process for updating the temporary schedule in consideration of the worker's educational opportunity (step S6), and after the update A schedule output process (step S7) for outputting the schedule to the output unit 4 is executed. In the schedule output process (step S7), the schedule updated in step S6 is output to the output unit 4, so that the output unit 4 performs display output and print output.
Hereafter, each process of said step S1-S6 is explained in full detail using FIGS.

(Step S1)
First, in the education execution item setting process in step S1, the control unit 1 sets education execution items for the packing methods P1 to P3 in response to a user operation on the operation unit 3. The education execution item setting process is executed by the education execution item setting function 10 of the control unit 1. It should be noted that the education execution item may be set only for one or a plurality of packing methods that need to provide an educational opportunity among the packing methods P1 to P3.
Here, the education execution items include the number of continuous work processes (hereinafter referred to as “the number of continuous operations”) necessary for effectively performing education for workers for each of the packing methods P1 to P3, The priority which determines the priority which provides the educational opportunity of each packing method P1-P3 is contained (refer FIG.5 (b)). The number of continuous operations indicates the continuous continuous operation time required to effectively educate the workers for each of the packing methods P1 to P3 as the number of operations for one lot of coils. . Note that time or the number of coils may be used instead of the number of continuous operations.

Specifically, as shown in FIG. 5A, the control unit 1 first sets the number of continuous operations for each of the packing methods P1 to P3 in accordance with a user operation on the operation unit 3 (Step S1). S11). Here, as shown in FIG. 5B, it is assumed that the number of continuous operations for each of the packing methods P1 to P3 is set to two.
Subsequently, the control unit 1 sets a priority for each of the packing methods P1 to P3 in accordance with a user operation on the operation unit 3 (step S12). Here, as shown in FIG. 5B, it is assumed that the priorities of the packing methods P1 to P3 are set to “1”, “2”, and “3”, respectively.
Thereafter, the control unit 1 stores the number of continuous operations and the priority set for each of the packing methods P1 to P3 in the storage unit 2 as education execution items (step S13). The education execution items stored here are used in a schedule update process in step S6 described later.

(Step S2)
Next, in the provisional schedule creation process in step S2, the control unit 1 schedules work processes included in the production schedule based on the production schedule (see FIG. 3) transmitted from the host computer Y. To create a temporary schedule. Here, the provisional schedule creation process is executed by the provisional schedule creation function 11 of the control unit 1.
Specifically, as shown in FIG. 6A, the control unit 1 first reads out the production schedule stored in the storage unit 2 (step S21).
Subsequently, the work steps related to the coils A1 to A10 included in the production schedule are rearranged in the order of the arrival times C1 to C10 to create a temporary schedule (step S22). At this time, since the work steps are arranged in the order of the arrival times B1 to B10, it is possible to prevent excess of the coil accommodation capacity of the arrival place shown in FIG. It should be noted that the present invention is not limited to this, and it is also conceivable as another embodiment that the work steps are arranged in order of the shipping times C1 to C10.
Then, the control unit 1 stores the temporary schedule in the storage unit 2 (step S23).
In step S2, as shown in FIG. 6 (b), a temporary schedule is created in which work steps related to the coils A1 to A10 are arranged in the order of the arrival times B1 to B10. In the temporary schedule, work numbers 1 to 10 corresponding to the execution order are assigned to the work steps related to the coils A1 to A10.

(Step S3)
Subsequently, in the work start time calculation process of step S3, the control unit 1 calculates a work start time for each work process of the coils A1 to A10 in the temporary schedule. The work start time calculation process is executed by the work start time calculation function 12 of the control unit 1.
Here, the work start time indicates the latest work process start time at which the shipping times C1 to C10 can be observed. That is, the work start time includes the work times K1 to K3 from the shipping times C1 to C10, and the transport time by the crane or belt conveyor between the coil shipping site and the work site and between the work site and the coil shipping site in FIG. Is the time minus. Therefore, when each work process is started according to the work start time, the work process can be completed in time for the shipping times C1 to C10.

Specifically, as shown in FIG. 7A, the control unit 1 first sets a work number of a work process for which the work start time is calculated (step S31). Here, the control unit 1 sets the work number as L, and adds one by one from the initial value 0 (L = L + 1).
Subsequently, the control unit 1 calculates the work start time for the work process having the work number designated in step S31 (step S32), and adds the calculated work start time to the temporary schedule (step S32). S33).
Then, in the next step S34, the control unit 1 determines whether or not the calculation of the work start time has been completed for all the work processes having the work numbers 1 to 10. Specifically, here, the control unit 1 determines whether or not the work number L has reached 10. If it is determined in step S34 that the calculation of the work start time has been completed for all work processes having the work numbers 1 to 10, the step S3 is ended.
Thereby, in the said step S3, work start time is calculated about all the work processes of the said work numbers 1-10. Here, as shown in FIG. 7B, it is assumed that work start times TS1 to TS10 are calculated for the work numbers 1 to 10.

(Step S4)
Next, in the work end time calculation process of step S4, the control unit 1 calculates the work end time for each work process of the coils A1 to A10 in the temporary schedule. Here, the work end time calculating process is executed by the work end time calculating function 13 of the control unit 1.
Here, the work end time indicates the time at which the work steps of the coils A1 to A10 are finished. Specifically, the work end times of the coils A2 to A10 are the same as the work end time of the previous work step, the own work times K1 to K3, and the coil shipping place to the work place and the work place to the coil in FIG. It is the time when the transportation time by the crane and the belt conveyor between the shipping sites is added.
On the other hand, since the coil A1 having the work number 1 has no previous work process, the work end time is calculated assuming that the work is performed starting from the arrival time B1 of the coil A1. . That is, the work end time of the coil A1 is the work time K1 at the arrival time B1, and the transport time by the crane or the belt conveyor between the coil shipping site and the work site and between the work site and the coil shipping site in FIG. Is the time added.

Specifically, as shown in FIG. 8A, the control unit 1 first sets a work number of a work process for which the work end time is calculated (step S41). Here, the control unit 1 sets the work number as L, and adds one by one from the initial value 0 (L = L + 1).
Subsequently, the control unit 1 calculates the work end time for the work process having the work number designated in step S41 (step S42), and adds the calculated work end time to the temporary schedule (step S42). S43).
Then, in the next step S44, the control unit 1 determines whether or not the calculation of the work end time has been completed for all the work processes having the work numbers 1 to 10. Specifically, here, the control unit 1 determines whether or not the work number L has reached 10. If it is determined in step S44 that the calculation of the work end time has been completed for all the work processes having the work numbers 1 to 10, the step S4 is finished.
Thereby, in the said step S4, work end time is calculated about all the work processes of the said work numbers 1-10. Here, as shown in FIG. 8B, it is assumed that work end times TE1 to TE10 are calculated for the work numbers 1 to 10.

(Step S5)
Thereafter, in the work condition satisfaction determination process of step S5, the control unit 1 performs the work based on the work start times TS1 to TS10 and the work end times TE1 to TE10 calculated in steps S3 and S4. It is determined whether each of the work processes with work numbers 1 to 10 is scheduled in time for the shipping times C1 to C10 (step S5).
That is, in the step S5, it is determined whether or not it is possible to satisfy the shipping times C1 to C10 (an example of delivery date), which are work conditions set in the production schedule. The work condition satisfaction determination process is executed by the work condition satisfaction determination function 14 of the control unit 1.

Specifically, as shown in FIG. 9A, the control unit 1 first sets a work number of a work process to be determined (step S51). Here, the control unit 1 sets the work number as L, and adds one by one from the initial value 0 (L = L + 1).
Subsequently, the control unit 1 calculates a time difference between the work start time and the work end time for the work process having the work number designated in step S51 (step S52).
And the said control part 1 determines whether the time difference calculated by the said step S52 is 0 or more (step S53). Thereby, the control unit 1 determines whether or not each of the work steps of the work numbers 1 to 10 is in time for the shipping times C1 to C10, that is, whether or not the work conditions are satisfied.
Here, in the present embodiment, when the work start times TS1 to TS10 are calculated (see FIG. 7A) and when the work end times TE1 to TE10 are calculated (see FIG. 8A). In both cases, the working times K1 to K3 are taken into consideration.
Thus, in step S5, it is determined that the shipping times C1 to C10 are satisfied on the condition that the actual working time is twice as long as the working times K1 to K3. Become. That is, in the scheduling process, processing is performed so as to ensure twice the work time.

If it is determined that the shipping times C1 to C10 are satisfied (Yes in step S53), “OK” is added to the temporary schedule as the determination result for the work process (step S54). On the other hand, when it is determined that the shipping times C1 to C10 are not satisfied (No in step S53), “NG” is added to the provisional schedule as the determination result for the work process (step S55).
Thereafter, the control unit 1 determines whether or not the determinations for all the work processes of the work numbers 1 to 10 have been completed (step S56), and if determined to have ended (Yes side of step S56). , Processing proceeds to step S57.
In step S57, the control unit 1 determines whether or not the determination results for all work processes with the work numbers 1 to 10 are “OK”. Here, when it is determined that the determination results for all work processes are “OK” (Yes in step S57), step S5 is ended. On the other hand, when it is determined that the determination result is “NG” even in any one of the work steps (No side of step S57), the process proceeds to step S58, and the scheduling error by the control unit 1 occurs. Processing is executed. In the scheduling error process, for example, the scheduling process is terminated without proceeding to the next step S6, and an error display for the output unit 4 is performed.

(Step S6)
And in the schedule update process of the said step S6, the said control part 1 rearranges the execution order of the work process of the work numbers 1-10 in the said temporary schedule based on the said education execution item, and updates this temporary schedule Schedule update processing is executed. Here, the schedule update process is executed by the schedule update function 15 of the control unit 1.
The scheduling apparatus X according to the present invention is characterized by the method of the schedule update process. Specifically, the scheduling process X is performed using the work times of work numbers 1 to 10 in the temporary schedule as the shipping times C1 to C10. Scheduling so as to provide the continuous work time for educating the worker for any one or more of the work steps based on the education execution items within a range that can be satisfied (a range in which work conditions can be satisfied). Is to do.
Hereinafter, the schedule update process will be described with reference to FIGS. 10 and 11.

As shown in FIG. 10, first, the control unit 1 reads the education execution item (see FIG. 5B) and the provisional schedule (FIG. 9B) from the storage unit 2 (step S61). As described above, the education execution item includes the number of continuous operations and the priority.
Next, in step S62, the control unit 1 sets the priority as N, and adds one by one from the initial value 0 (N = N + 1). Thereby, it becomes an object of a rearrangement in an order from a work process with a high priority.

Subsequently, the control unit 1 sets the work number as L, and adds one by one from the initial value 0 (step S63). Whether the priority of the work process of the work number L matches the priority N or not. Is determined (step S64). That is, a work process whose priority is the priority N is searched from the work processes of the work numbers 1 to 10.
If it is determined in step S64 that the priority of the work process with the work number L does not match the priority N (No in step S64), the process proceeds to step S641. In step S641, the control unit 1 determines whether or not the search for all work processes having the work numbers 1 to 10 has been completed. Specifically, here, the control unit 1 determines whether or not the work number L has reached 10. If it is determined in step S641 that the search for all work processes having the work numbers 1 to 10 has been completed (Yes in step S641), the process proceeds to step S78 described later. Until the search for all the work steps with the work numbers 1 to 10 is completed (No side of step S641), the process returns to step S63.

On the other hand, when it is determined in step S64 that the priority of the work process with the work number L matches the priority N (Yes in step S64), the process proceeds to step S65.
And the said control part 1 uses the said work number L of the work process determined that the priority is the said priority N in the said step S64 as the said reference | standard work number LS at the time of rearranging a work process, and the said memory | storage part 2 (Step S65).

Next, the control unit 1 sets the work number L to retrieve whether or not there is a work process with the priority N among work processes after the work number next to the reference work number LS. One by one is added (step S66).
In step S67, the control unit 1 determines whether or not the priority of the work process with the work number L matches the priority N. That is, a work process having a priority N is searched from work processes related to work numbers after the reference work number LS.
If it is determined in step S67 that the priority of the work process with the work number L does not match the priority N (No in step S67), the process proceeds to step S671. In step S671, the control unit 1 determines whether or not the search for all work processes having the work numbers 1 to 10 has been completed. Specifically, here, the control unit 1 determines whether or not the work number L has reached 10. If it is determined in step S671 that the search for all work processes having the work numbers 1 to 10 has been completed (Yes in step S671), the process proceeds to step S78 described later. Until the search for all the work steps with the work numbers 1 to 10 is completed (No side in step S671), the process returns to step S66.

On the other hand, when it is determined in step S67 that the priority of the work process with the work number L matches the priority N (Yes in step S67), the process proceeds to step S68.
In step S68, the control unit 1 rearranges the work processes in the provisional schedule so that the work process with the work number L is inserted next to the work process with the reference work number LS.

Here, a specific example of rearrangement so far will be described. In the education execution item shown in FIG. 5B, the priority of the packing method P1 is set to “1”, and in the provisional schedule shown in FIG. 9B, the priority is “1”. The work process of the coil number A1 using the packing method P1 is work number 1. Accordingly, the first reference work number LS is “1”, which is the work number of the work process of the coil number A1.
A work process having a priority “1” after work number 1, that is, a work process using the packing method P <b> 1 is a work process related to the coil number A <b> 4 of work number 4.
Accordingly, in step S68, as shown in FIG. 11A, the work process related to the coil number A4 of the work number 4 is inserted next to the work process related to the coil number A1 of the work process 1. Note that the work number of the work process after the original work number 2 is decremented.
Thereby, the work process of the packing method P1 is executed twice in succession, and it becomes possible to efficiently educate the workers of the work process related to the packing method P1.

By the way, if the work processes of the provisional schedule are rearranged in the step S68, any one or more of the work processes may not satisfy the shipping time. Therefore, at the time of step S68, the process proceeds to the subsequent step S69 without confirming the rearrangement (update) of the temporary schedule. At this time, the RAM of the control unit 1 temporarily stores both the temporary schedule before the rearrangement in step S68 and the temporary schedule after the rearrangement.
In steps S69 to S71, the control unit 1 determines whether or not all work processes satisfy the work conditions of the shipping times C1 to C10 in the temporary schedule updated in step S68. ing. Such determination is performed by the steps S3 to S5 (see FIGS. 7 to 9) executed by the work start time calculation function 12, the work end time calculation function 13 and the work condition satisfaction determination function 14 of the control unit 1. Since it is the same process, description is abbreviate | omitted here. 11A to 11D, the work start times calculated for the temporary schedules changed to the respective states are TS11 to TS20, TS21 to TS30, TS31 to TS40, and TS41 to TS50. The end times are TE11 to TE20, TE21 to TE30, TE31 to TE40, and TE41 to TE50, respectively, and the determination results (“OK” or “NG”) at that time are shown.

In step S72, the control unit 1 determines whether or not the determination result is “OK” for all the work processes performed in step S71.
Here, if it is determined in step S72 that the determination result is “OK” for all work processes (Yes in step S72), the process proceeds to step S73.
In step S73, the control unit 1 validates the rearrangement of the work processes in the temporary schedule and confirms the update of the temporary schedule. Specifically, the rearranged temporary schedule stored in the RAM of the control unit 1 is overwritten with the temporary schedule stored in the storage unit 2. Thus, in the scheduling process in the scheduling apparatus X, the provisional schedule is updated on condition that the work conditions are satisfied in all work processes. Thereafter, the process proceeds to step S74.

In step S74, the control unit 1 adds one counter M (initial value is “1”) indicating the number of times the work process of the priority N is continued (M = M + 1).
In step S75, the control unit 1 determines whether or not the counter M has reached the number of continuous operations set as an education execution item for the packing method used in the currently selected operation process. . If it is determined that the counter M has not reached the number of continuous operations (No in step S75), the process proceeds to step S751, and the control unit 1 sets the operation number L to the reference operation number. Stored as LS. Thereafter, the process returns to step S66.

On the other hand, if it is determined that the counter M has reached the number of continuous operations (Yes in step S75), the process proceeds to step S76, and the control unit 1 resets the counter M ( Counter M = 1).
In step S77, the control unit 1 determines whether or not the search process has been completed for all work processes having work numbers 1 to 10. Specifically, the control unit 1 determines whether or not the search process has been completed for all work processes by determining whether or not the work number L has reached 10.
Here, while it is determined that the search process has not been completed for all the work processes having the work numbers 1 to 10 (No in step S77), the process goes to step S63 after passing through step S723. The same processing is executed for the next work number and thereafter.
In step S723, the reference work number LS is substituted into the work number L. That is, the process after step S64 is executed again for the work process after the reference work number LS. Thus, for example, in the provisional schedule of FIG. 11A, the process returns to step S63 and the same processing is executed for the subsequent work numbers and thereafter, as shown in FIG. Next to the work process related to coil number A6, the work process related to coil number A8 corresponding to work number 8 is inserted.

On the other hand, if it is determined in step S77 that the search process has been completed for all the work processes having the work numbers 1 to 10 (Yes in step S77), the process proceeds to step S78.
In step S78, the control unit 1 determines whether or not the search process has been completed for all priorities. Here, the control unit 1 determines whether or not the search process has been completed for all priorities by determining whether or not the priority N is “3”.
Here, if it is determined that the search processing has been completed for all priorities (Yes side of step S78), the temporary schedule is determined as a regular schedule and stored in the storage unit 2 (step S79). The process of step S6 is ended. As described above, in the subsequent step S7, the schedule updated by the control unit 1 in the step S6 is output.

On the other hand, if it is determined that the search process has not been completed for all priorities (No side of step S78), the process proceeds to step S781.
In step S781, the control unit 1 resets the work number L (work number L = 0), and the process returns to step S62. As a result, one priority N is added in the step S62, and the processing after the step S63 is executed again. Thereby, for example, as shown in FIG. 11C, the temporary schedules are rearranged so that the packing method P2 having the priority “2” is continuous.

Here, as shown in FIG. 11C, it is assumed that “NG” is generated in the determination result in the step S71. Specifically, in the example shown in FIG. 11C, a result that the work process after work number 5 cannot satisfy the shipping time is obtained.
In such a case, in step S72, it is determined that the determination result is not “OK” for all work processes (No in step S72), and the process proceeds to step S721.
In step S721, the control unit 1 cancels the work process rearrangement in step S68 and invalidates it, and returns to the temporary schedule before the rearrangement. For example, the provisional schedule in FIG. 11C is returned to the provisional schedule in FIG. Specifically, the rearranged temporary schedule stored in the RAM of the control unit 1 is erased, and the temporary schedule stored in the storage unit 2 is not overwritten.

Thereafter, in step S722, the control unit 1 determines whether or not the search process has been completed for all work processes. Specifically, the control unit 1 determines whether or not the search process has been completed for all work processes by determining whether or not the work number L has reached 10.
If it is determined that the search process has been completed for all work processes (Yes in step S722), the process proceeds to step S78, but if it is determined that the search process has not been completed (No in step S722). Side), the process returns to the step S66 via the step S723, and the same process is executed for the next work number and thereafter. For example, as shown in FIG. 11D, after the work process related to the coil number A8 using the packing method P2 having the priority “2”, the coil number A10 using the packing method P2 is used. Such a work process is inserted.

As described above, in the schedule update process of step S6, the priority included in the education execution items for the plural types of packing methods P1 to P3 is high within a range where at least the shipping time can be satisfied. In order from the work process, scheduling is performed so as to ensure an educational opportunity to continuously execute the work process.
As a result, when the temporary schedule created in step S2 has a time margin, it is possible to provide an educational opportunity for each work process within the margin and efficiently educate the worker. it can.

In the present embodiment, a case will be described in which the control unit 1 performs scheduling so as to provide educational opportunities in stages in a preset order for each of a plurality of types of work processes. For example, scheduling may be performed so that educational opportunities for work processes at higher skill levels are only provided after educational opportunities for work processes at lower skill levels are secured. It is done.
Specifically, the configuration described in the embodiment will be described as an example. As an educational opportunity for the packing method P1 having a priority “1”, the time required for the education of the packing method P1 was secured. In this case, scheduling is performed so as to provide an educational opportunity for the packaging method P2 having the next highest priority, and when the time required for education of the packaging method P1 is not secured, the scheduling method is more than the packaging method P1. It is conceivable to perform scheduling so as not to provide an educational opportunity for the low-priority packing method P2 and the packing method P3.

As described above, by scheduling the educational opportunities for the packing methods P1 to P3 in the order of high priority set in advance, it is possible for an operator who has not mastered the packing method P1 having a high priority. , By not teaching the packing method P2 and the packing method P3, which have a lower priority than that, it is possible to educate workers in stages. For example, when the priority is regarded as the difficulty level or the risk level, it is possible to perform scheduling so that an operator with a low skill level is not trained about a work process with a high difficulty level or a high risk level.
Furthermore, in the schedule update process (see FIG. 10) described in the above embodiment, regardless of whether or not the education execution item of the work process with the highest priority is satisfied, Scheduling was performed so as to provide an educational opportunity. However, according to the configuration of this embodiment, if the education execution item of the work process with the highest priority is not satisfied, the work process with the next highest priority is performed. The processing load is reduced because the processing for providing the educational opportunity is not performed.

  By the way, the determination as to whether or not the educational opportunities for each of the packing methods P1 to P3 are provided is not limited to whether or not the continuous working time for the education is secured. For example, the educational opportunities provided intermittently are determined. Judgment may be made cumulatively. For example, when scheduling is performed every week, when the training opportunity of the packing method P1 is secured by the scheduling of the first week, half of the time required for the education of the packing method P1 is secured, the next second week It is conceivable to perform scheduling so as to secure the other half during scheduling. Then, when an educational opportunity for the time necessary for education of the packing method P1 is provided in the schedule over several weeks, scheduling is performed so as to provide the packing method P2 having the next highest priority.
