Background technique

In an article production facility, various operations that need to be dealt with may occur during the operation of the facility. There are not only operations that can be performed without stopping the production of articles, but also operations that cannot be performed without stopping the production. When a work requiring corresponding work occurs, it is necessary to search for the place where the work occurred, investigate the cause of the occurrence, and take measures to execute the work. In the case of work that requires stopping the production of articles, such as work for solving a failure in the equipment, work for replacing and replenishing materials, etc. For a long time, there are concerns that the production of the item will not proceed as planned, that the required quantity and quality of the item cannot be produced by the required date, or that the equipment and the work of the operator will be overworked in order to achieve the production plan. load.

In a production facility for articles, a plurality of operators often work in teams to operate the facility. In a team composed of a plurality of workers, generally, a veteran worker with a high skill for the work required for the operation of the equipment to a new worker with a low skill and inexperience is arranged in a balanced manner. The same work can be completed in a short time and with high accuracy even if it is an experienced worker, but in the case of a new worker, it often takes time or results in a low-precision work. In addition, even the same operator has familiar tasks and inexperienced tasks. When a work for which correspondence is required occurs in the facility, an operator corresponding to the work is selected in consideration of various situations. For example, consider the following correspondence: for a simple task that can be handled in a short time, a new worker or a worker with low skills for the task is made to respond, and for a difficult task that requires a long time to cope with Experienced workers with high skills for this work will respond.

When a certain work that should be handled is required in the facility, a technology is proposed from the viewpoint of automatically selecting an operator corresponding to the work, and providing appropriate education to the operator, as disclosed in Patent Documents 1 to 1. The technology disclosed in Patent Document 4.

Patent Document 1 relates to a worker education system for enabling workers to be educated in a short period of time at the time of production line planning, and to appropriately arrange workers with appropriate skill levels on the line. In this system, based on skills indicating familiarity standardized for each work process of a production line, workers with an appropriate skill level are searched for, placed on the line, and the skill rank of each worker can be determined. , implement training when needed. Training is performed based on educational tools that the operator can learn by himself or a schedule provided by the system.

Patent Document 2 relates to the fact that, by reflecting the skill level of the worker, the arrangement status of the worker's work process, and the actual result of the worker's education in real time, these data can be grasped in a unified manner, and it is possible to improve the production efficiency or improve the worker's performance. Auxiliary system for breeding program assistance. In this system, the skill level of the worker is evaluated based on the manufacturing actual result and the educational actual result, and staffing is performed in consideration of the skill level. If there is an operator who has not reached the skill level, the system will extract it and make an education plan for the operator. Education for low-skilled workers is planned for off-hours when no work sequence is assigned.

Patent Document 3 relates to a system that can automatically extract an appropriate operator to perform work in a product manufacturing line, and improve the operator's skills by allowing the operator to receive appropriate education at an appropriate time. In this system, when a new task is performed, based on the processing level including one of the accuracy and speed when the worker performs the task, and the performance level of the test to which the worker takes a test, it is possible to extract the appropriate number of tasks to be performed. skilled workers.

Patent Document 4 relates to a system that can perform assignments to operators of projects in consideration of changes in the skills of operators when creating a project execution plan such as maintenance work or construction work. In this system, for each work constituting the workflow of the project, the estimated work time based on the standard according to the skill level of the operator and the actual work time of the operator in charge of each work that has already been performed are used to determine the current work time of the operator. The skill level is calculated and updated, and the estimated work time for each job can be calculated based on the updated skill level of the worker assigned to each job.

Detailed ways

Hereinafter, embodiments of the operator selection system according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram showing a schematic configuration of an operator selection system 100 according to an embodiment of the present invention. The operator selection system 100 includes a function unit capable of receiving a notification that a job requiring correspondence has occurred in the equipment P (job generation notification), and outputting information of an operator that should correspond to the job (corresponding operator information), and Various judgments, calculations, etc. are performed based on the information of the job generation notification; and a storage section stores various information used to perform the function.

The operator selection system 100 includes a work information storage unit 102 , a worker information storage unit 104 , a work skill information storage unit 106 , and a production-related information storage unit 108 . The job information storage unit 102 stores information related to jobs required in the facility. The operator information storage unit 104 stores information on the operator and information related to the operator's past work. The work skill information storage unit 106 stores information on the work skill of each worker corresponding to the work generated in the facility. The production-related information storage unit 108 stores production-related information of articles produced by the facility.

For the information stored in each storage unit, it is not necessary to physically aggregate work information, worker information, work skill information, and production-related information, respectively. For example, in a state where data corresponding to work skill information and data corresponding to operator information coexist, the data is not limited to being stored in one piece of hardware, and these data may be stored in a state of being dispersed in a plurality of pieces of hardware In this case, the area where data corresponding to worker information other than the work skill information is stored corresponds to the worker information storage unit 104 , and the area where data corresponding to the work skill information is stored corresponds to the work skill information storage unit 106 .

The job information stored in the job information storage unit 102 is information related to a job required in the device, and can be, for example, the information shown in FIG. 4 . The information shown in FIG. 4 includes, for example, the state of the device, the cause of the state, the basis for judging the work required to correspond to the state of the device, the content of the required work, the time required for the work, the timing of the work, and the like. form.

The operator information stored in the operator information storage unit 104 includes information on an operator who can perform work required in the facility and information on the operator's past work. Worker information includes, for example, in addition to the name, ID number, department, etc. of the worker, the content of the work performed by the worker in the past, the time required to correspond to the work, the date and time when the work was performed, and the work performed. the results of the work, etc.

The work skill information stored in the work skill information storage unit 106 includes information related to the work skill of each worker corresponding to the work generated in the facility. Examples of work skills will be described later.

The production-related information of the article stored in the production-related information storage unit 108 can be, for example, the production capacity of the device, the production plan of the article (production volume, production days, production deadline, production safety, production margin, etc.), the production capacity of the article, and the like. Produce actual results, etc.

The operator selection system 100 preferably further includes a sensor data storage unit 109 that stores sensor data such as sensors that monitor the state of each part of the plant P. The sensor data is used together with work information, for example, and can be used as data for determining a required work.

As shown in FIG. 1 , the operator selection system 100 can include a work classification unit 110 , a work inexperienced person determination unit 112 , a work skill deviation estimation unit 114 , a work skill determination unit 116 , a work allowable time calculation unit 118 , and a work Completion possibility determination unit 120 , work skill improvement possibility determination unit 122 , worker selection unit 124 , and information update unit 126 . The functions of the functional units 110 to 126 will be sequentially described below.

The storage units 102 to 109 may be configured as one hardware database or may be configured as a distributed database. Similarly, each of the functional units 110 to 126 of the operator selection system 100 may be constructed in one piece of computer hardware, may be constructed in a plurality of pieces of computer hardware that are distributed, or may be constructed so that each piece of computer hardware is linked to each other. function of each department.

The operator selection system 100 can be used, for example, in an RTP system apparatus to automatically select an operator corresponding to a work required for the operation of the apparatus. In the RTP method, in the production process of a liquid crystal display device or the like, from a tape-shaped optical film laminate in which a plurality of sheet-shaped optical films are supported on a tape-shaped release film via an adhesive layer, only normal ones that do not have defects are The sheet-like functional film is sequentially peeled from the release film together with the adhesive layer, and is bonded to a rectangular panel via the adhesive layer to continuously manufacture a liquid crystal display device. A continuous manufacturing system for realizing such a liquid crystal display device is called "continuous pasting (RTP; roll-to-panel" device.

FIG. 2 shows an exemplary computer hardware configuration of the operator selection system 100 according to the embodiment of the present invention. The operator selection system 100 can use a storage device such as a central processing unit (CPU), a RAM, ROM, and a hard disk drive (HDD) that stores various programs and data executed by the central processing unit, and a storage device that connects these devices. The bus is implemented by a general-purpose computer. Furthermore, in the operator selection system 100, a drive device for inputting and outputting data to and from an external recording medium such as a CD-ROM or DVD-ROM, an input device such as a keyboard or a mouse, a CRT, a An output device such as a liquid crystal display or a printer is connected to a communication interface for communicating with another computer or a network.

FIG. 3 shows a process flow 300 executed in the operator selection system 100 to select an operator who performs work. For example, in the equipment P such as the RTP apparatus, when some event requiring work occurs, the equipment P notifies the operator selection system 100 that the corresponding event has occurred ( S301 ). The fact that an event to be corresponded to occurs in the device P can be detected by various measuring devices such as sensors attached to a plurality of places in the device P, for example. For example, in the RTP apparatus, in the step of bonding the optical film to the liquid crystal panel, when the accuracy of the bonding position of the optical film deteriorates, after stopping the operation of the apparatus, the operator checks the situation, and if necessary It is necessary to perform, for example, correction of bonding parameters or replacement of feed rollers. In such a case, the bonding position detection system detects an abnormality and, for example, notifies the operator selection system 100 that the bonding accuracy has deteriorated from an information processing terminal having a function of collectively collecting abnormality information.

When notified that a corresponding event has occurred, the operator selection system 100 acquires, based on the notified information, the job information storage unit 102 that stores information about the job required in the facility, the job information associated with the event. Job information. An example of job information is shown in FIG. 4 . The work classification unit 110 of the operator selection system 100 performs classification judgment of the work based on the acquired work information, and determines the content of the work to be associated ( S302 ).

For example, when notified that the bonding accuracy has deteriorated, the operator selection system 100 acquires, from the work information storage unit 120 , the cause of the state, the basis for determining the work required, the work required, and the work place. Information such as the time required, the timing of the work to be performed, etc. Based on the information and the sensing data from each part of the equipment P, the job classification unit 110 determines the necessary operation when the cause of the deterioration in accuracy is the deterioration of the bonding roller and the replacement of the bonding roller has not been performed for a certain period of time. The job is "replacement of the bonding roller". The work classification unit 110 can also specify the time required for the work or the timing at which the work should be performed, as necessary.

In addition, the classification determination of the target work is desirably performed automatically by the operator selection system 100 using, for example, a predetermined abnormality code or data shown in FIG. When the accuracy deteriorates, the operator determines the cause based on various sensor data, past experience, workbooks, etc., determines the required work, and provides the determined work content to the operator selection system 100 from the input unit to perform the operation. . In addition, when an unset event such as an abnormality code occurs, the operator selection system 100 may determine the work content by analogy from the information stored in the work information storage unit 120 .

Next, when the work to be corresponded is identified, the operator selection system 100 includes the information of the operator and the information about the operator who has performed the work in the past with respect to a plurality of operators related to the operation of the equipment P and capable of supporting the work. The operator information of the work-related information is acquired from the operator information storage unit 104 in which the information is stored. When the operator selection system 100 acquires operator information, in the work inexperienced person determination unit 112, it is determined whether there is an inexperienced person with respect to the work specified in S302 (S303). When there is no inexperienced person, the operator selection system 100 then stores the information about the work skill corresponding to the work, that is, the work skill information, based on the operator information of the plurality of workers. obtained from the work skill information storage unit 106 .

The work skill is the work performance ability of an operator who performs the work in the facility when certain work related to the facility is required. The index indicating the work skill is not particularly limited as long as it can express the ability of the worker to perform the work, and various indexes are considered. Job skills are expected to be quantitative indicators, but can also be qualitative indicators. In the case of using a qualitative index as the work skill, it is preferable that the system can automatically use a value obtained by converting the index into a certain numerical value. In the worker selection system 100 of the present invention, it is preferable to use a quantitative numerical value indicating the work performance ability of each worker as the work skill.

As the work skill, for example, the average value of the time required for the work when the work was performed in the past, the shortest work time among the times required for the work when the work was performed in the past, and the number of times the work was performed in the past can be used. , the movement distance, movement time and other values when the operation is performed. FIG. 7 to be described later shows an example in which the shortest work time among the times required to respond to the work in the past is the work skill.

Alternatively, as the work skill, the accuracy of the result of the work performed in the past or a value calculated based on a separately determined skill level can also be used. FIG. 5 shows an example in which the skill level values are weighted and summed as work skills. FIG. 5 shows a combination of skills required to perform a job identified as necessary by using the skill level value assigned based on a separate evaluation (for example, a job training table) for each worker regarding each job, and using a pair of Each skill level value is weighted and summed or averaged as a map of work skills. In the example of FIG. 5 , for example, when the work of No. 3 occurs, the skill of each operator is calculated based on the weights in the items of “RTP basics” and “quality abnormality measures” of the work training table. The work skill values of Worker A, Worker B, Worker C, and Worker D are 2.4, 3.3, 1.9, and 1.0, respectively. Therefore, the worker with the highest skill is worker B, and the worker with the lowest skill is worker D.

In the following description of this specification, the case where the shortest work time among the work time required by each worker to respond to the work in the past is used as the work skill will be described as an example. Returning to FIG. 3 , it is determined in S303 that there is no inexperienced person, and after acquiring the work skill information of a plurality of workers, the worker selection system 100 obtains a plurality of tasks in the work skill deviation estimation unit 114 The size of the deviation of the work skills among the workers is determined ( S305 ). In addition, the process ( S304 ) when it is determined in S303 that there is an inexperienced person will be described later.

FIG. 6 is an example of a case of calculating the magnitude of variation in work skills among a plurality of workers. For example, when the workers A to E are the workers who can handle the work, the work skill deviation estimation unit 114 acquires the shortest work time in the past work of all the workers. Calculate the difference (same as (3)) between the shortest time ((1) in Fig. 6) and the longest time (same as (2)) among the obtained shortest work hours, and divide the difference by the shortest work time (same as ( 4)), thereby obtaining the magnitude of the deviation of the work skills of the workers A to E in the work. In the case of the example of FIG. 6 , the magnitude of the variation in work skills is calculated as “2.0”.

Next, the work skill determination unit 116 of the worker selection system 100 compares the magnitude of the deviation estimated by the work skill deviation estimation unit 114 with a predetermined reference value related to the magnitude of the deviation ( S306 ). When it is determined that the magnitude of the variation in the work skill is equal to or greater than the predetermined reference, the work skill determination unit 116 extracts the worker with the lowest work skill (Yes in S306 ). On the other hand, when it is determined that the magnitude of the variation in the work skill is smaller than the predetermined reference, the work skill determination unit 116 extracts the worker with the highest work skill (No in S306 ).

FIG. 7 shows an example of a pattern in which one of a low-skilled worker and a high-skilled worker is selected according to the magnitude of the variation in work skills. FIGS. 7( a ) and ( b ) are examples of a case where the work to be supported is a simple work, and FIGS. 7( c ) and ( d ) are an example of a case where the work to be supported is a difficult work. For example, an example will be described when there is a difference in the work level between the operators of the work at the start of the operation of the equipment, and a simple work that should be handled occurs (the case of FIG. 7( a )). When the job is generated in the period (initial stage) when the number of occurrences of the job is high, and the magnitude of the deviation of the work skill is calculated as 2.0, the predetermined reference is set to 1.0, and the extracted worker becomes the worker E. (ie, low-skilled workers). When the operation of the equipment continues and the number of occurrences of the job gradually decreases, when the same job is generated at one of the times (middle and late), the deviation of the work skill is calculated in the same way, and the deviation is calculated as 9.0 and 2.0, so both jobs are extracted. E.

Here, the predetermined reference is arbitrarily set, but as an example, the predetermined reference can be set in the following thinking. That is, when the predetermined reference is set to 1.0 and the magnitude of the deviation calculated in S305 is 1.0 or more, the working time (the shortest time) of the high-skilled worker and the working time (the longest time) of the low-skilled worker ), there is a difference of more than 2 times, so the improvement of the work skills of low-skilled workers is sought. On the other hand, when the magnitude of the deviation is less than 1.0, it is considered that there is no significant difference in work skills among workers, and further skill improvement of highly skilled workers is sought.

When there is no difference in the work level between the operators of the work at the start of the operation of the equipment, when a simple work that should be handled occurs (the case of FIG. 7( b )), the same In the calculation and judgment, the operator A or the operator B (ie, the high-skilled worker) is extracted in each of the initial stage and the middle stage, and the worker E (ie, the low-skilled worker) is extracted in the later stage. When a relatively difficult work that should be handled occurs, there is a difference in the work level between the operators of the work at the start of the operation of the equipment (the case of FIG. 7( c )) and there is no work level. Even in the case of poor performance (the case of FIG. 7( d )), a low-skilled worker or a high-skilled worker is appropriately extracted at each time point according to the magnitude of the deviation.

Returning to FIG. 3 , when a low-skilled worker or a high-skilled worker is extracted by the work skill determination unit 116 , the worker selection unit 124 selects one of the workers as the corresponding worker corresponding to the job, and outputs the worker information (S307 or S308). The outputted operator information can be displayed on, for example, a portable information terminal held by each operator, a monitor installed in the device P, or the like. The operator output to these information terminals performs required work in accordance with the event generated in the equipment P (S309).

When the work is completed, the corresponding operator who performed the work or his manager inputs work completion information including details of the work, work time, etc., for example, from a portable information terminal or an input terminal provided in the device P ( S310 ). When the information update unit 126 of the operator selection system 100 acquires the input job completion information, it uses the information to update any one of the job information, the worker information, and the job skill information stored in the storage unit, or any of them, as needed. The combination is updated (S311). Alternatively, the information update unit 126 automatically acquires the start time and end time of the job, details of the job, and the like, and uses these information to update one of the job information, worker information, and job skill information stored in the storage unit, or a combination thereof to update.

When the work inexperienced person determination unit 112 determines that there is an inexperienced person for the work specified in S302 ( S303 ), the work skill deviation estimation unit 114 acquires a preset for the inexperienced person from the worker information storage unit 104 . specified temporary work skills. The information set as the temporary work skill can be set based on the index used as the work skill. For example, when using the shortest work time among the times required to respond to the work in the past as the work skill, it is possible to set other workers to perform the work in the past as the temporary work skill of the inexperienced person. The longest work time among the work time at the time of work. Alternatively, it is also possible to set the average value of the work time when other workers performed the work for the first time in the past as the temporary work skill.

The temporary work skills of the inexperienced person can also be preset as described above and stored in the work skill information storage unit 106 as work skill information, but can also be automatically set by the operator selection system 100 . For example, when the shortest time is used as the work skill, the operator selection system 100 can obtain from the operator information storage unit 104 in response to the work inexperienced person determination unit 112 determining that there is an inexperienced person for the required work. The work time when other workers performed the work in the past is compared, and the longest work time is set as the temporary work skill, and stored in the work skill information storage unit 106 .

Next, when selecting a worker corresponding to a job, a worker selection process in which the time allowed for execution of the job is taken into consideration will be described. FIG. 8 shows a processing flow 800 when the time allowed for the job is considered in the operator selection processing. In the following description, parts different from the flow of FIG. 3 will be mainly described.

In the process flow 300 of FIG. 3 , when an event requiring work occurs, the deviation of the work skills of a plurality of workers is calculated for the work, and when the magnitude of the deviation is greater than or equal to a predetermined reference, the operator with the lowest work skills is determined. Extract the operator who performed the job. However, when some event that requires work occurs, it may be necessary to stop the operation of the equipment P, and the production of articles may stop during the stoppage of the operation. Therefore, when a worker with low work skills may take time to complete the work and the required production volume may not be achieved, the worker cannot be allowed to perform the work, and it is necessary to enable the work to be performed in a shorter time. The operator of the job performs the job. Therefore, in the processing flow 800, the allowable time for achieving the required production plan even if the operation of the plant P is stopped is compared with the work time required for the extracted operator to perform the work, and it is determined whether the operator can When the work is completed within the allowable time, and the work time of the operator is higher than the allowable time (allowable stoppage time for the work), other workers are extracted.

In step S803 of the processing flow 800, when it is determined that there is no inexperienced person for the work specified in S802, the work allowable time calculation unit 118 of the operator selection system 100 calculates the allowable time for the work ( S805). Note that the calculation of the allowable time is not limited to being performed at this time. For example, it may be calculated after extracting the worker with the lowest work skill in S808.

FIG. 9 shows an example of the concept of calculation of the allowable time. In FIG. 9, the horizontal axis represents time, and the vertical axis represents the production amount of articles. For example, the operation of the equipment is stopped when the required work occurs in the equipment, and the production is restarted after a certain stop time. When the production plan can be achieved by the deadline, the predetermined stop time can be set as the "allowable time". The allowable time can be longer if the actual production results so far when the job is generated is higher than the production volume specified in the production plan. In addition, for example, depending on how much the expected change in the production volume after the restart of the work is relative to the change in the production volume before the work is started, how much the safety of the production is expected, and the production plan has relative to the production capacity of the equipment. The time calculated as the allowable time varies depending on the degree of the margin metric and other conditions.

For example, the allowable time calculated based on the idea shown in FIG. 9 is passed to the work completion possibility determination unit 120, and the work completion possibility determination unit 120 determines the shortest work time for the work of the low-skilled worker extracted in S808. Compare with the allowable time (S810). If the shortest work time is shorter than the allowable time as a result of the comparison, the work completion possibility determination unit 120 determines that the low-skilled worker can complete the work, and the worker selection unit 124 selects the low-skilled worker as the The corresponding operator for this job.

On the other hand, as a result of comparing the allowable time with the shortest work time of the low-skilled worker for the work ( S810 ), if the shortest work time is equal to or longer than the allowable time, the work completion possibility determination unit 120 determines that the work is the work. The person cannot complete the assignment within the time allowed. In this case, the work skill determination unit 116 extracts the worker with the lowest work skill among the workers other than the worker among the plurality of workers ( S811 , S812 , and S808 ). Similarly for the operator, the work completion possibility determination unit 120 compares the allowable time and the shortest work time.

As a result of repeating the steps from S808 to S812, if it is determined in S812 that there are no job candidates remaining, the worker selecting unit 124 selects the worker with the shortest working time among all workers as the job The corresponding operator of , so that the work can be completed in the shortest possible time ( S813 ).

In S807 and S808, when a low-skilled worker is extracted as described above, when a high-skilled worker is extracted, the same process is performed (S807, S809, S814 to S817).

Next, when selecting a worker corresponding to a job, a worker selection process that takes into consideration the possibility of improving the work skill of the worker who performs the job will be described. FIG. 10 shows a processing flow 1000 in the case of considering the possibility of improvement of the operator's work skills in the operator selection process. In the following description, parts different from the flow of FIG. 3 will be mainly described.

In this system, the deviation of the work skills of a plurality of workers is calculated, and when the magnitude of the deviation is greater than or equal to a predetermined reference, a low-skilled worker is extracted as a worker who performs the work. Here, considering the improvement of the skills of the entire team composed of a plurality of workers, for example, when there are a plurality of workers with the same level of work skills, it is desirable to select the work that can be expected by performing the work. Skilled worker. Therefore, in the processing flow 1000, when it is determined that the improvement of the work skill is possible, the operator is directly extracted in consideration of the change in the work skill of the extracted worker in the past, and when it is determined that the work skill is improved It is impossible to extract other operators.

In step S1009 of the processing flow 1000, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility of the worker selected in S1007. The possibility of improving the work skill is determined by obtaining, for example, a change in the work time of the worker in the past for the work (for example, the work time over the past multiple work or the work time of the previous work). The work skill improvement possibility determination unit 122 acquires the extracted work hours of the worker in the past a plurality of times from the work information storage unit 102, and compares these work times. Then, it is determined that the work skill improvement in the work of the operator is possible.

On the other hand, the work-skill-improvement possibility determination unit 122 compares the extracted work time of the worker a number of times in the past, and if there is no tendency for the work time to shorten every time the work is performed, it is determined that the work time of the operator is Homework skill improvement in this assignment is not possible. In this case, the work skill determination unit 116 extracts the worker with the lowest work skill among the workers other than the worker among the plurality of workers ( S1010 , S1011 , and S1007 ). Similarly for the worker, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility.

As a result of repeating the steps from S1007 to S1011, when it is determined in S1011 that there are no job candidates remaining, the worker selection unit 124 selects the worker with the highest job skill among all workers as the worker corresponding to the job The corresponding operator of the job ( S1012 ).

In S1006 and S1007, when a low-skilled worker is extracted as described above, when a high-skilled worker is extracted, the same processing is performed (S1006, S1008, S1013 to S1016).

Next, when selecting a worker corresponding to a job, a worker selection process in which the time allowed for performing the job and the possibility of improving the work skill of the worker performing the job will be described. FIG. 11 shows a processing flow 1100 in the case where both the allowable time of the work and the possibility of improving the work skill are taken into consideration in the operator selection process. In the following description, parts different from the flow of FIG. 3 will be mainly described.

In step S1103 of the process flow 1100, when it is determined that there is no inexperienced person for the work specified in S1102, the work allowable time calculation unit 118 of the operator selection system 100 calculates the work allowable time in S1105. The calculation of the work permission time is not limited to being performed at this time. For example, it may be calculated after extracting the workers with the lowest work skills in S1108. The idea of the calculation of the job allowable time is described in the description of the processing flow 800 in FIG. 8 .

Next, in step S1110, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility of the worker selected in S1108. The possibility of improving the working skills is described in the description of the processing flow 1000 in FIG. 10 . The work skill improvement possibility determination unit 122 acquires the extracted work hours of the worker in the past a plurality of times from the work information storage unit 102, and compares these work times. Then, it is determined that the worker has a high possibility of improving the work skill in the work.

Next, in step S1111, the work completion possibility determination unit 120 compares the shortest work time for the work with the work allowable time for the low-skilled worker determined in S1110 to be highly likely to improve the work skill. If the shortest work time is shorter than the work allowable time as a result of the comparison, the work completion possibility determination unit 120 determines that the low-skilled worker can complete the work, and the worker selection unit 124 selects the low-skilled worker is the corresponding operator corresponding to the job.

When it is determined in step S1110 that the improvement of the work skill of the worker is impossible, or when it is determined in S1111 that the low-skilled worker cannot complete the work, the work skill determination unit 116 among the plurality of workers Among the other workers other than the worker, the worker with the lowest job skill is extracted ( S1112 , S1113 , and S1108 ). Similarly for the worker, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility, and the work completion possibility determination unit 120 determines the work completion possibility.

In addition, in the process flow 1100, for the low-skilled worker extracted in S1108, the possibility of improving the work skill is determined in S1110, and the determination of the possibility of completing the work is performed in S1111, but the order of these determinations may be reversed. .

As a result of repeating the steps from S1108 to S1113, if it is determined in S1113 that there are no job candidates remaining, the worker selecting unit 124 selects the worker with the shortest working time among all workers as the corresponding worker The corresponding operator of the job can complete the job in the shortest possible time (S1114).

When a low-skilled worker is extracted in S1007 and S1008, it is as described above, but also when a high-skilled worker is extracted, the same processing is performed (S1107, S1109, S1115 to S1119).

FIG. 12 shows a specific example of work skill improvement in the case where the operator selection process flow 1110 shown in FIG. 11 is executed. FIG. 12( a ) is a specific example of improvement of work skills for simple tasks (that is, tasks for which the work time is relatively short), and FIG. 12( b ) is for more complicated tasks (that is, tasks for which the work time is relatively long). A specific example of the improvement of the work skills of the work). In any case, it is assumed that one of the workers performs the work in the team consisting of five workers A to E, and the shortest work time of the work is defined as the work skill.

For the first work in FIG. 12( a ), the work time of Worker A or Worker B with the shortest work time (the initial setting value is set to 5 minutes) and the work time of Worker E with the longest work time are used (The initial setting value is set to 15 points.) When the magnitude of the deviation of the work skill is calculated, it becomes "2.0" as shown in the column of (4). If the predetermined reference value is set to 1.0, since the magnitude of the deviation is equal to or greater than the predetermined reference value, the operator E is extracted. When comparing the extracted worker E with the shortest work time (15 minutes) and the work allowable time (100 minutes) calculated based on, for example, the idea of FIG. 9 , it is determined that the worker E is within the work allowable time. Since the work can be completed, here the operator E (new person) is selected as the corresponding operator who performs the work. If the operator E performed the work and the work was completed in 12 minutes, the minimum work time for the work by the operator E is updated to 12 minutes.

When the second work occurs, the magnitude of the deviation is larger than the predetermined reference value, and it is determined that the worker E who has the longest work time can complete the work within the work allowable time. Furthermore, it is determined that the worker E The shortest work time (15 minutes) set initially is short (12 minutes), and the work skills may be improved even after the first work is completed, so the operator E is selected as the corresponding operator here. Similarly, when the third and fourth operations have occurred, the operator D and the operator C are respectively selected as the corresponding operators.

When the fifth work occurs, using the work time of Worker A or Worker B with the shortest work time (5 minutes) and the work time of Worker E with the longest work time (9 minutes), the deviation of work skills is calculated. size. The magnitude of the deviation is "0.8", which is a value smaller than the predetermined reference value, so the operator A or the operator B is extracted here. It is judged that these workers can complete the work within the shortest work time, so here, the worker A or the worker B is selected as the worker who performs the work. In addition, regarding which of the worker A and the worker B is finally selected as the corresponding worker, it is desired to follow the judgment result of the possibility of improving the work skill, but when the possibility of growth is the same (see Fig. 12(a) ) ), the past work time transition of both is the same), and can be selected using other arbitrary criteria. Here, it is assumed that worker A (experienced worker) is selected as the corresponding worker.

Hereinafter, also in the case where the sixth to tenth operations have occurred, a corresponding operator is similarly selected. In this way, by sequentially selecting workers in ten operations, the skills of the workers E with low work skills are improved, and as a result, the skills of the entire team can also be improved.

To describe the example shown in FIG. 12( b ), first, when the first work occurs, the magnitude of the variation in work skills is calculated in the same manner as described above. Since the magnitude of the deviation is "0.7", if the predetermined reference value is set to 1.0, the worker A with the highest work skill is extracted. The worker's shortest work time is set to 60 minutes, which is shorter than the work allowable time of 95 minutes. Therefore, it is determined that the worker can finish the work within the time, and worker A (experienced worker) is selected as the corresponding worker.

Next, when the second work occurs, the magnitude of the variation in work skill is 1.0 or more, so the worker E with the lowest work skill is extracted. However, since the minimum work time of the work by the operator E is set to 100 minutes, which is longer than the work allowable time of 95 minutes, it is determined that the operator E cannot complete the work within the work allowable time. In this case, among the workers other than the worker E, the worker with the lowest work skills, that is, the worker D, is selected as the corresponding worker (in addition, the worker C and the worker D are selected for the The basis of the operator D can be based on an arbitrary standard). Hereinafter, also in the case where the third to seventh operations have occurred, a corresponding operator is similarly selected.

When the eighth work occurs, the magnitude of the deviation is 0.9, and the shortest work time of the operator A is within the work allowable time, so the operator A should be extracted. However, when the worker A was selected as the corresponding worker for the seventh work and performed the work, there was no effect of shortening the work time, so it was determined that the improvement of the work skill was impossible. Therefore, here, for the remaining workers B to E, the magnitude of the deviation and the possibility of completing the work are determined, and as a result, the worker B is selected as the corresponding worker. In this way, by sequentially selecting the workers in 10 operations, not only the skills of workers C to E with low skills are improved, but also the skills of workers A and B are improved, and as a result, the team can also be improved. Overall skill improvement.

As described above in detail, according to the present invention, not only the work skills of low-skilled persons can be rapidly improved, but also the work skills of high-skilled persons can be further improved for various operations required in equipment. In addition, it is possible to improve the work skills as a whole work team composed of a plurality of operators involved in the operation of the equipment.
