Description

  The present invention relates to an operator determination support apparatus.

  Patent Document 1 describes a system that determines the placement of workers who can develop the capabilities of workers without causing any problems in production planning. The system changes the worker arrangement so that a highly skilled worker who can assist the worker in the process is arranged in the vicinity when the production plan is disturbed.

  Patent Document 2 describes an apparatus that can assign an appropriate worker to work according to the status of a production plan. The apparatus calculates a margin of work time for the work plan, and selects a worker based on the margin and the work ability of each worker. When the margin is high, a worker with low work ability is preferentially selected, and when the margin is low, a worker with high work ability is preferentially selected.

JP 2000-172758 A JP 2008-158971 A

  According to the technique described in Patent Literature 2, when the margin is high, an operator with low work ability is always selected. However, there are cases where workers to be trained should target workers with moderate work ability, regardless of workers with low work ability. Furthermore, in the case of causing a worker with low work ability to perform the work, comparing the case where a large number of workers are performed with a large number of workers performing a large amount of work concentrated on a specific worker, the former Can be expected to improve working ability.

  An object of this invention is to provide the operator determination assistance apparatus which can improve a worker's working capability more effectively.

  The worker determination support device of the present invention includes a process plan storage unit that stores a process plan in which an execution order related to processing by a plurality of processing machines and work by a worker on a plurality of processing machines is defined, Regarding a plurality of work types, an ability database for storing work ability for each work type for each worker, a plurality of work education subjects who require work education among a plurality of workers, and a plurality of work education subjects A work education list including work education priorities, a busy schedule of the process plan, a capability database, and a worker worker determination unit that determines a worker in charge of performing the work in the process plan based on the work education list.

  The worker-in-charge determination unit prioritizes a worker with a high work ability based on the work ability stored in the ability database when the busyness of the process plan is high. In addition, when the busyness of the process plan is low, the worker-in-charge determining unit prioritizes the worker training target who has a higher work education priority in the work education list and determines the worker in charge.

  When the busyness is high, the worker in charge is determined with priority given to the worker with high work ability based on the work ability stored in the ability database. Therefore, even if the busy schedule of the process plan is high, the work can be executed without causing a delay in the process plan. On the other hand, when the busyness is low, the worker in charge is not determined based on the work ability, but is determined based on the work education list. Here, the work education list is not directly related to the work ability, and even if the worker has a high work ability or a worker with a low work ability, the work education priority can be increased. . And the work education subject with a high work education priority order becomes a worker in charge preferentially. That is, a specific work education target person with high work education priority can intensively accumulate many work experiences. Therefore, it is possible to effectively improve the work ability of the work education target person.

(1. First embodiment)
(1-1. Configuration of target equipment)
The target equipment of the operator determination support device 10 will be described with reference to FIG. The worker determination support device 10 determines a worker in charge from among a plurality of workers A-F for each work in the process plan in a process plan using equipment constituted by a plurality of processing machines MC1-MC4. . The plurality of processing machines MC1 to MC4 are, for example, a production facility that produces various objects, a logistics machine that conveys the objects, and the like. The processing machines MC1 to MC4 as production equipment are machine tools such as a machining center, a lathe, and a grinding machine, and are arranged in a line.

(1-2. Configuration of Worker Determination Support Device 10)
The configuration of the operator determination support device 10 will be described with reference to FIGS. As shown in FIG. 2, the worker determination support device 10 includes a capability database 11, a process plan storage unit 12, a busyness acquisition unit 13, a work education list 14, and a worker determination unit 15.

  As shown in FIG. 3, the capability database (DB) 11 is an index value Lv indicating the height of work capability for each work type for each worker A-F with respect to a plurality of workers A-F and a plurality of work types. (Upper stage), unit work time (middle stage) for deriving the index value Lv, and total work time (lower stage) are stored. Here, the work types are classified according to the parts a to d to be produced and the processing machines MC1 to MC4 to be used. For example, in the case of the part a, since the three processing machines MC1-MC3 are used, each of the processing machines MC1-MC3 is classified as each work type.

  The unit work time is the shortest time required for one work of the target work type in the past. In addition, the unit work time may be the latest time required for one work when the work of the target work type is recently performed. In addition, when work of the work type is frequently performed, the unit work time is the shortest time, and when work of the work type is performed only a few times, for example, twice a year, the unit work time is The working time may be the latest time.

  The index value Lv indicating the height of work ability is determined based on the unit work time. For example, the index value Lv becomes higher as the unit work time is shorter, and becomes lower as the unit work time is longer. In the present embodiment, the index value Lv exemplifies five stages of 0 to 4. Index value Lv. 0 corresponds to the work ability of an inexperienced person or a person close thereto. Index value Lv. 4 corresponds to the skilled worker's working ability. The index value Lv. 1-Lv. 3 is Lv. The closer to 4, the higher the work capacity.

  In addition, a standard work time is set for each work type. The standard work time is the index value Lv. 3-Lv. The average unit work time by four workers is assumed. For example, when the unit work time is equal to or less than the standard work time, the index value Lv indicating the work ability of the worker is Lv. 4. Further, the index value Lv. 1-Lv. Also for No. 3, the boundary time is set based on the standard work time.

  The total work time shown in the lower part of each column in FIG. 3 is the total time of work performed in the past for work of the target work type. That is, the total work time is an index relating to the experience level of the work. Therefore, it can be considered that the work ability is higher as the total work time is longer among a plurality of workers having the same index value Lv indicating the work ability. For example, the index value Lv. The plurality of skilled workers 4 can be regarded as having a higher skill level as the total work time is longer.

  Here, the unit work time and the total work time stored in the ability database 11 are updated by acquiring the work time measured by the ability measuring device 2, as shown in FIG. For example, the capability measuring device 2 considers the work time while recognizing that the worker is present in the work area set in the vicinity of the processing machine MC1. The capability measuring device 2 is not limited to the above method, and various methods can be applied.

  As shown in FIG. 4, the process plan storage unit 12 stores a process plan in which an execution order relating to processing by the plurality of processing machines MC1 to MC4 and work by the workers A to F on the plurality of processing machines MC1 to MC4 is defined. Remember. For example, the process plan storage unit 12 stores a process plan for one day.

  In FIG. 4, a white frame is a work by the workers A-F, and a hatched frame is a process by the processing machines MC1-MC4. FIG. 4 illustrates the case where the setup work by the workers A-F is performed before the processing by the processing machines MC1-MC4. For example, the part a needs to be processed in the order of the processing machines MC1, MC2, and MC3, and the setup work by the worker A-F is performed at each preceding stage of the processing machines MC1 to MC3.

  Here, the process plan is determined in advance by the administrator based on, for example, the production plan of the object. Furthermore, in the process plan, the work by the worker is set based on the standard work time described above. That is, when each work is performed in the standard work time, it is executed according to the process plan.

  The busyness acquisition unit 13 acquires the busyness input by an input operation of the external device 3 by an operator such as an administrator. An operator such as an administrator judges the busyness of the next day by browsing the process plan of the next day, for example, and inputs the busyness of the next day through the external device 3. The busyness may be two levels of high and low, or may be three or more levels.

  As shown in FIG. 5, the work education list 14 includes a plurality of work education subjects AC that require work education among a plurality of workers AF, and work of a plurality of work education subjects AC. Includes education priorities. For example, work education priority is No. No. 1 is the worker A, and is the worker A. The second person for work education is the worker B.

  The work education list 14 is set by, for example, an administrator, and an operator who wants the administrator to perform work intensively is set at the top of the work education list 14. In other words, the work education target person A-C can include workers with high work ability regardless of work ability, or can be only workers with low work ability. For example, a worker D who generally has a high work ability can be a target for work education. Furthermore, the work education list 14 can increase the priority of work education regardless of whether the work ability is high or the work ability is low. For example, the worker D who has a high work ability is assigned the work education priority No. It can also be set to 1.

  Furthermore, the work education list 14 specifies the worker himself and is irrelevant to the work type. Here, as shown in FIG. 3, the work ability of the worker A-F varies depending on the work type. For example, for the work type of the processing machine MC2 for the part c, the index value indicating the work ability of the worker A is Lv. 2 but the index value indicating the work ability of the worker B is Lv. 1. That is, for the work type, worker A has a higher work ability than worker B. However, for other work types, worker A has a lower work ability than worker B. As described above, the work ability of the worker varies depending on the work type, but in the work education list 14, the work education priority order is set regardless of the work ability.

  The person-in-charge determination unit 15 determines a person in charge who performs each work in the process plan based on the busyness of the process plan acquired by the capability database 11, the busyness acquisition unit 13, and the work education list 14. . Processing performed by the worker determination unit 15 will be described with reference to FIG.

  The responsible worker determination unit 15 acquires the busyness of the process plan acquired by the busyness acquisition unit 13 (S1). Subsequently, the worker worker determination unit 15 determines whether or not the acquired busyness is high (S2). For example, if the busyness is high or low, it is determined whether the busyness is high, or if the busyness is acquired in three or more levels, the busyness is higher than a predetermined value. Is determined to be high.

  When it is determined that the degree of busyness is high (S2: Y), the worker worker determination unit 15 determines a worker worker for each work by using the capability database 11 (S3). The determination mode in this case is called a busy mode. Specifically, the worker worker determination unit 15 prioritizes a worker having a high index value Lv indicating work ability in the busy mode, and determines a worker in charge. Therefore, even if the busy schedule of the process plan is high, the work can be executed without causing a delay in the process plan.

  For example, the index value Lv. 3-Lv. The worker in charge is determined with priority given to the worker 4. Of course, the worker in charge may be determined in descending order of the index value Lv indicating the work ability. That is, the index value Lv. 4 is determined as the worker in charge with the highest priority, and then the index value Lv. The third worker may be determined as the worker in charge.

  In this case, the index value Lv. When there are a plurality of workers, the worker worker determination unit 15 may use the total work time in addition to the index value indicating the work ability. That is, the worker-in-charge determination unit 15 determines a worker in charge with priority given to a worker having a long total work time among workers having a high index value Lv indicating work ability.

  If there are a plurality of target tasks at the same time, the worker in charge is assigned in order from the task with the earliest start time. The worker in charge of each work in the busy mode is as shown in FIG. For example, for the work of the processing machine MC1 for the part a ((1) in FIG. 7), the worker E has the highest index value Lv. 4. Therefore, the worker in charge of the work is designated as worker E. The same applies to workers in charge of other work ((2) to (6) in FIG. 7).

  Also, the worker determination unit 15 determines the index value Lv.2 when the busyness is three or more and the busyness is the highest. 4 is preferentially determined as the worker in charge, and the index value Lv. 3-Lv. The worker 4 may be preferentially determined as the worker in charge.

  On the other hand, if it is determined that the degree of busyness is low (S2: N), the worker worker determination unit 15 uses the work education list 14 without using the ability database 11, and the worker worker in charge of each task. Is determined (S4). The determination mode in this case is referred to as an education mode. Specifically, the worker-in-charge determination unit 15 determines a worker in charge in the education mode by giving priority to a worker education target person who has a high work education priority in the work education list. Work education priority No. Since the worker 1 who has a high work education is the worker A, the worker A is preferentially the worker in charge.

  If there are a plurality of target tasks at the same time, the worker in charge is assigned in order from the task with the earliest start time. The worker in charge of each work in the education mode is as shown in FIG. Work education priority No. The person A who is subject to work education 1 performs the work of the processing machine MC1 for the part a ((1) in FIG. 8), the work of the processing machine MC3 for the part d ((6) in FIG. 8), and the processing machine for the part a. It becomes a worker in charge of the work of MC3 ((3) of FIG. 8). Thus, a specific work education target person with high work education priority can intensively accumulate many work experiences. Therefore, it is possible to effectively improve the work ability of the work education target person.

(2. Second embodiment)
The worker determination support apparatus 20 of 2nd embodiment is demonstrated with reference to FIG. As shown in FIG. 9, the worker determination support device 20 includes a capability database 11, a process plan storage unit 12, a busyness determination unit 21, a work education list 14, and a worker determination unit 15. In addition, about the structure similar to 1st embodiment among each structure, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  The busyness determination unit 21 determines the busyness by executing a computer program based on the process plan stored in the process plan storage unit 12. For example, the busyness determination unit 21 acquires the time when all of the work by the workers A-F and the processing by the processing machines MC1 to MC4 are completed from the process plan, and determines the busyness based on the completion time. May be. Further, the busyness determination unit 21 acquires the length of the blank time in which there is no work by the workers AF and processing by the processing machines MC1-MC4, and determines the busyness based on the length of the blank time. May be.

  In this case, it is not necessary to make a human decision as to whether or not the degree of busyness is high, and the influence of variations in human judgment can be suppressed. As a result, by making a more appropriate determination between the busy mode and the education mode, it is possible to prevent delays in process planning and to secure many opportunities for work education.

(3. Third embodiment)
In the worker determination support apparatus 10 of the third embodiment, the processing by the worker determination unit 15 will be described with reference to FIG. In addition, about the step similar to 1st embodiment among each step, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  When it is determined that the busyness is low (S2: N), the worker worker determination unit 15 determines a worker worker for each work using the work education list 14 (S4). Then, the worker worker determination unit 15 determines the progress of the process plan when the worker worker is determined with priority given to the work training target person AC (S41). The progress of the process plan corresponds to the progress of actual results when compared with the process plan. When there is no actual delay, the degree of progress is high, and when there is a delay, the degree of progress is low.

  When the degree of progress is high (S42: Y), the worker worker determination unit 15 continues the determination of the degree of progress. On the other hand, when the degree of progress is low (S42: N), the worker worker determination unit 15 uses the capability database 11 to prioritize a worker with high work ability and determines a worker in charge (S43). When the progress is extremely low, if the education mode is continued, the work scheduled for today may not be completed. Therefore, the worker-in-charge determination unit 15 switches from the education mode to the busy mode and determines a worker in charge of the subsequent work. In this way, by switching modes in the middle, even if the degree of progress is extremely low at a certain point in time, the work scheduled for today can be completed in time.

(4. Fourth embodiment)
The configuration of the operator determination support device 30 according to the fourth embodiment will be described with reference to FIGS. The worker determination support device 30 includes a capability database 11, a process plan storage unit 12, a busyness acquisition unit 13, a work education list 14, a leader education list 31, and a responsible worker determination unit 32. In addition, about the structure similar to 1st embodiment among each structure, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  As shown in FIG. 12, the leader education list 31 includes a plurality of leader education subjects DF that require leader education among a plurality of workers AF, and a plurality of leader education subjects D. -Includes F leader education priorities. For example, the leader education priority is No. No. 1 instructor for training is worker D. The second instructor for instructor training is worker E.

  The leader education list 31 is set by, for example, an administrator, and an operator who wants the administrator to give instruction intensively is set higher than the leader education list 31. That is, the instructor for training DF DF can be only a worker with a high work ability regardless of work ability, or can include a worker with a low work ability. However, normally, a worker who has a high work ability as a whole is set as a leader education target person D-F.

  Based on the busyness of the process plan acquired by the capability database 11, the busyness acquisition unit 13, and the work education list 14, the responsible worker determination unit 32 determines a worker who performs each work in the process plan. . Furthermore, the worker-in-charge determination unit 32 determines a leader for the worker in charge based on the leader education list 31. Processing performed by the worker determination unit 32 will be described with reference to FIG. In addition, about the step similar to 1st embodiment among each step, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  When it is determined that the busyness of the process plan is low (S2: N), the worker worker determination unit 32 determines a worker worker for each work using the work education list 14 (S4). And the worker determination part 32 in charge determines the leader education subject DF with high leader education priority in the leader education list 31 as a leader for the worker AC in charge (S21). ). Teacher education priority No. Since the person with a high work education of 1 is the worker D, the worker D preferentially becomes the instructor.

  When there are a plurality of target tasks at the same time, the leaders are assigned in order from the task with the earliest start time. The instructor of each work in the education mode is as shown in FIG. Teacher education priority No. The instructor D 1 instructor 1 performs the operation of the processing machine MC1 of the part a ((1) in FIG. 14), the operation of the processing machine MC3 of the part d ((6) in FIG. 14), and the processing of the part a. It becomes an instructor about the work of the machine MC3 ((3) in FIG. 14). In this way, a specific leader education target with high leader education priority can intensively gain many teaching experiences. Accordingly, it is possible to effectively improve the teaching ability of the instructor to be trained.

(5. Fifth embodiment)
In the worker determination support device 30 of the fifth embodiment, processing by the worker determination unit 32 will be described with reference to FIGS. 15 and 16. In addition, about the step similar to 4th embodiment among each step, the same code | symbol is attached | subjected and description is abbreviate | omitted.

  When it is determined that the busyness of the process plan is high (S2: Y), the worker worker determination unit 32 uses the capability database 11 to give priority to a worker with a high index value Lv indicating work capability. A worker in charge for each work is determined (S3).

  Subsequently, the worker worker determination unit 32 determines the worker education target person AC having a higher job education priority in the work education list 14 as a visitor who accompanies the worker worker (S31). The workers in charge and visitors of each task in the busy mode are as shown in FIG. Work education priority No. The person A who is subject to work education 1 performs the work of the processing machine MC1 of the part a ((1) in FIG. 16), the work of the processing machine MC3 of the part d ((6) of FIG. 16), and the processing machine of the part a. It becomes a visitor about the work of MC3 ((3) of FIG. 16).

  In the busy mode, the work education target person A-C is less likely to be a worker in charge. Therefore, the work education target person A-C can acquire the know-how of the skilled work by attending the work person with high work ability and observing the skilled work by the worker. And even if a specific work education target person with high work education priority is not a worker in charge, he / she can frequently observe skilled work. Therefore, it is possible to effectively improve the work ability of the work education target person.

(6. Sixth embodiment)
The worker determination support apparatus 10 according to the sixth embodiment will be described with reference to FIG. In the work education list 14, initially, the work education priority is No. No. 1 is the worker A, and is the worker A. The person who is subject to work education No. 2 is worker B, 3 is the worker C.

  Workers with higher work education priority can gain more work experience. However, if this state is continued, it is difficult for workers with lower work education priorities to gain work experience. Therefore, as shown in FIG. 17, the work education priority order in the work education list 14 is sequentially changed every time a predetermined period has elapsed since the last change. This change process is automatically performed by the computer.

  For example, the highest work education subject A moves to the lowest position, and the ranks of other work education subjects BC are raised. By doing in this way, each specific work education subject AC can concentrate and can acquire work experience for every predetermined period. As a result, the work ability of many work education subjects AC can be effectively improved.

(7. Seventh embodiment)
The worker determination support apparatus 10 according to the seventh embodiment will be described with reference to FIG. In the leader education list 31, the leader education priority is No. 1 in the initial stage. No. 1 instructor for training is worker D. No. 2 instructor for training is worker E. The third leader education target person is the worker F.

  Workers with higher rankings for teacher training can gain more teaching experience. However, if this state is continued, it is difficult for an operator who has a lower leadership education priority to gain experience in teaching. Therefore, as shown in FIG. 18, the leader education priority order in the leader education list 31 is sequentially changed every time a predetermined period has elapsed since the last change. This change process is automatically performed by the computer.

  For example, the highest leader education target person D moves to the lowest position, and the ranking of the other leader education target persons E-F is raised. By doing in this way, every specific leader training subject DF can accumulate and acquire teaching experience for every predetermined period. As a result, it is possible to effectively improve the teaching ability of many leader training subjects D-F.
