Description

Operator selection system, operator selection method and operator selection computer program

The present invention relates to a system for automatically selecting an operator corresponding to a necessary operation in a device, and more specifically, to automatically selecting an operation corresponding to the operation based on the operation skill information of a plurality of operators The operator chooses the system.

In the production equipment of articles, various operations that must be handled may occur during the operation of the equipment. As operations that must be dealt with, there are not only operations that can be performed without stopping the production of articles, but also operations that cannot be performed without stopping production. When an operation that must be dealt with occurs, you have to find the place where the operation occurred, investigate the cause, and formulate countermeasures for the operation. Among the operations that must be dealt with, when there are operations that have to stop the production of items, such as operations to solve problems in equipment or operations to replace and supplement materials, the time it takes to complete the operation If it is too long, it will not be possible to produce the goods as planned, and it may not be possible to produce the necessary quantity and quality of goods before the required deadline, or the operation of equipment and operators will be forced to achieve the production plan.

In the production equipment of articles, most operators are organized into teams to operate the equipment. In a group of multiple operators, there are usually veteran operators with high skills for the tasks necessary for the operation of the equipment, and even new operators with inexperienced and low skills. Even if it is the same task, veteran operators can complete it in a short time and with high accuracy, but in the case of novice operators, it may take time or result in low-accuracy results. In addition, even the same operator will have familiar and inexperienced assignments. When a job that needs to be handled occurs in the equipment, the operator who is ordered to handle the job is selected in consideration of various conditions. For example, the following response can be envisaged, that is, if it is a simple task that can be handled in a short time, a novice operator or a low-skilled operator for the task is instructed to respond, and for difficult tasks that must be dealt with for a long time Order the veteran workers who are skilled in the job to respond.

In the case of certain tasks that should be handled in the equipment, the operator who is ordered to handle the task is automatically selected, and the correct education is given to the operator. In terms of the proposed technology from this point of view, there are patent documents 1-Patent Document 4 Discloser. Patent Document 1 relates to an operator education system designed to educate operators in a short period of time when planning a production line, so that operators with correct skill levels can be correctly deployed on the production line. In this system, based on the standardization of the operation engineering of each production line to indicate the familiarity of the skill, the operator with the correct skill level is searched for, placed in the production line, and when the skill level of each operator must be determined Able to implement training. Training is based on the schedule provided by the educational tool or system that the operator can self-learn.

Patent Document 2 relates to a support system designed to instantly reflect the skill level of the operator, the status of the operator's assignment to the work project, and the operator's educational performance, and to master these data in a coordinated manner, thereby improving production efficiency and Or support the training program for operators. In this system, the skill level of the operator is evaluated by manufacturing performance and educational performance, and the skill level is considered for staffing. In the system, if there is an operator who has not reached the skill level, it will be selected and an education plan for the operator will be made. The education for low-skilled operators is planned to be conducted during non-operational hours when no work is assigned.

Patent Document 3 relates to a system that is designed to automatically extract suitable operators to perform operations in the production line of products, and to receive appropriate education at the appropriate time for the operators, thereby Seek to improve the skills of operators. In this system, when a new job is performed, based on the processing level of one of the accuracy and speed of the operator’s work, and the level of the test performed by the operator, it is possible to extract those who should be engaged in the work. Operators with appropriate skills.

Patent Document 4 relates to a system that is designed to consider changes in the skill of the operator when preparing a project execution plan for maintenance work or engineering work, and assign operators to the project. In this system, for each job that constitutes the work flow of the project, the work time can be estimated based on the standard corresponding to the skill level of the operator, and the actual work time of the operator in charge of each work that has been carried out can be calculated and updated. Based on the updated skill level of the operators assigned to each job, the estimated work time for each job is calculated. [Prior Technical Literature] [Patent Literature]

[The problem to be solved by the invention]

The system constructed based on the thinking method proposed in Patent Documents 1 to 4 is designed to be able to automatically select an appropriate operation based on the skills of each operator when a work that must be dealt with occurs in the equipment. The operator of the job. However, if an operator is selected by these systems when an operation occurs, for example, new operators are always assigned to simple tasks, and veteran operators are always assigned to difficult tasks. If such assignments continue, there will be There is a problem that it is difficult to quickly improve the job skills of new operators. In addition, the operation of equipment is generally carried out by multiple operators in groups. However, if the skills of low-skilled operators are not improved, it is impossible to expect the improvement of equipment operation skills of the entire group, or even further efficiency of product production. It will become difficult.

In addition, in the systems proposed in Patent Documents 1 to 3, although education for improving the skills of operators is also taken into consideration, none of the techniques has been adopted to make the skills of the work inferior. The operator actually experiences the assignment to improve his skills. The operator education implemented in these systems is designed to be carried out separately from the operation of the equipment, and the operator whose skill level has been improved as a result of the education can handle tasks corresponding to the skill level. Therefore, the ideal is to create an opportunity for novice operators to respond to difficult tasks that occur during actual equipment operation, and to design an effective education that is closer to the actual situation.

In order to solve the above unsolved problems, the purpose of the present invention is to provide an automatic operator selection system in equipment, which can quickly improve the skills of low-skilled operators. [Technical means to solve the problem]

In a first aspect of the present invention, there is provided an operator selection system for automatically selecting an operator who responds to a necessary operation in a facility from among a plurality of operators. The operator selection system is equipped with: a memory section, which stores information about necessary operations in the equipment, that is, operation information, and operator information including information about multiple operators and information about the operations performed by each operator in the past, And the information about the operation skills of the plurality of operators who deal with the aforementioned tasks for the task is also the task skill information. The memory part can also store production-related information of the items produced by the equipment.

The operator selection system has an operation skill determination unit, an operator selection unit, and an information update unit. The job skill judging unit, when a task that must be dealt with occurs, obtains job information, operator information, and job skill information from the memory unit, judges the level of job skill of the job among multiple workers, and extracts multiple jobs Low-skilled workers with the lowest job skills among the workers. The operator selection unit selects the extracted low-skilled operator as the operator responding to the job, and outputs the operator information of the responding operator. The information update part updates one or a combination of the operation information, the operator information, and the operation skill information of the memory part based on the result that the responding operator selected by the operator selection part responded to the operation.

In one embodiment, the operator selection system can also be designed to further have: a work skill improvement possibility judging unit, which can obtain the past work skills of the work for the low-skilled workers extracted by the work skill judging unit Based on the change, the possibility of improvement of work skills is determined based on the change. In addition, the operator selection system can be designed to further include: a work inexperienced person judging section, which judges whether there is an operator who has not performed the work experience among the plurality of operators, and when there is the operator, the operator Set hypothetical job skills for the job.

The operator selection system can also be designed to have: a work allowable time calculation unit, which obtains production-related information from the memory unit, and calculates the allowable time to achieve the production plan even if the operation of the equipment is stopped for work; and the possibility of completion of the work The judging unit judges whether the low-skilled workers extracted by the work skill judging unit can complete the task within the allowable time.

In a second aspect of the present invention, there is provided an operator selection method for automatically selecting an operator who responds to a necessary operation in a facility from among a plurality of operators. In addition, in the third aspect of the present invention, a computer program that can be executed on a computer system is provided, which includes commands for the computer system to execute each step of the method selected by the operator. [Effects of Invention]

According to the present invention, it is possible to quickly improve the working skills of low-skilled workers for various operations necessary in the equipment.

In the following, referring to the drawings, the embodiment of the operator selection system of the present invention will be described in detail.

FIG. 1 is a block diagram showing the schematic configuration of an operator selection system 100 according to an embodiment of the present invention. The operator selection system 100 can receive notifications of operations that must be handled in the equipment P (operation occurrence notifications), and output information of the operators who should respond to the operations (response operator information), including information based on the notifications of the operation occurrences The function part to perform various judgments and calculations, and the memory part to memorize various information used to perform the function.

The operator selection system 100 includes an operation information storage unit 102, an operator information storage unit 104, an operation skill information storage unit 106, and a production-related information storage unit 108. The operation information storage unit 102 stores information about necessary operations in the equipment. In the operator information storage unit 104, the information of the author and the information about the past work of the operator are stored. The work skill information storage unit 106 stores information on the work skill of each operator who responds to the work occurring in the equipment. The production-related information storage unit 108 stores production-related information of the articles produced by the equipment.

Regarding the information stored in each memory unit, operation information, operator information, operation skill information, and production-related information, each does not need to be physically integrated. For example, when data equivalent to job skill information is mixed with data equivalent to operator information, it is not limited to which hardware is stored collectively. The data can also be stored in a state of being distributed to multiple hardware In this case, the area storing data equivalent to the operator information other than the work skill information is equivalent to the operator information memory unit 104, and the area storing data equivalent to the work skill information is equivalent to the work skill information memory unit 106 .

The operation information memorized in the operation information storage unit 102 is information related to necessary operations in the equipment, and can be set as information as shown in FIG. 4, for example. The information shown in Figure 4 is, for example, a table that includes the status of the equipment, the reason for the status, the basis for determining the necessary work to deal with the state of the equipment, the content of the required work, the time required for the work, and The time of the job, etc.

The operator information memorized in the operator information storage unit 104 includes information about an operator who can perform necessary operations in the equipment, and information about the operator's past operations. Operator information, for example, in addition to the name, ID number, and deployment of the operator, it also includes the content of the operation performed by the operator in the past, the time required to respond to the operation, the date and time the operation was performed, and the result of the operation.

The work skill information memorized in the work skill information storage unit 106 includes information about the work skill of each operator who responds to the work occurring in the equipment. Examples of work skills will be described later.

The production-related information of the article memorized in the production-related information memory unit 108, for example, can be set as 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 performance of the article, etc.

The operator's selection system 100 preferably further includes a sensing data storage unit 109 that stores sensing data made by sensors that monitor the state of each part of the device P. The sensing data, for example, combined with operation information, can be used as data used to determine necessary operations.

The operator selection system 100, as shown in FIG. 1, can be ordered to include a work classification unit 110, a work inexperienced determination unit 112, a work skill determination unit 116, a work allowable time calculation unit 118, a work completion possibility determination unit 120, The work skill improvement possibility determination unit 122, the operator selection unit 124, and the information update unit 126. The functions of each function unit 110 to 126 will be described in order below.

The storage units 102 to 109 can be configured as a hardware database or a distributed database. Similarly, the operator selects each functional unit 110 to 126 of the system 100, which can be constructed in one computer hardware or in a plurality of scattered computer hardware, and is configured to perform the functions of each computer hardware in cooperation. The function.

The operator selection system 100 can be used, for example, in an RTP-based device to automatically select an operator who responds to tasks necessary for the operation of the device. The RTP method is a strip-shaped optical film laminate supported by a plurality of sheet-shaped optical films on a strip-shaped release film through an adhesive layer in the manufacturing process of liquid crystal display devices, etc., but there will be no disadvantages The normal sheet-like functional film and the adhesive layer are peeled from the release film in order, and the adhesive layer is attached to the rectangular panel to continuously manufacture the liquid crystal display device. The continuous manufacturing system of the liquid crystal display device that realizes this method is called a "Roll To Panel (RTP)" device, in order to bond a sheet of optical film cut in advance to a rectangular panel. The device of the individual attachment method is different.

FIG. 2 illustrates an exemplary computer hardware configuration of the operator selection system 100 according to an embodiment of the present invention. The operator selects the system 100 and can use a memory device such as a central processing unit (CPU), and RAM, ROM, hard disk drive (HDD), etc. storing various programs or data executed by the central processing unit, and these devices The interconnected buses are generally realized by computers. In addition, when the operator selects the system 100, if necessary, it can be designed as a magnetic disk device connected between external recording media such as CD-ROM or DVD-ROM for data input and output, and an input device such as a keyboard or mouse. , And output devices such as CRT, liquid crystal display or printer, and communication interface used to communicate with other computers or networks.

FIG. 3 shows a processing flow 300 executed in order to select an operator to perform the operation in the operator selection system 100. For example, in an equipment P such as an RTP device, when some situation that requires work occurs, the equipment P notifies the operator selection system 100 that a situation that should be handled has occurred (S301). When a situation that should be dealt with occurs in the device P, it can be detected by various measuring equipment such as sensors installed in plural places of the device P. For example, in the process of bonding optical films to liquid crystal panels in RTP devices, when the accuracy of the bonding position of the optical films deteriorates, it is necessary to stop the operation of the device, and the operator checks the situation and, if necessary, performs bonding. The correction of the integrated parameters or the replacement of the feed roller. In such a situation, the bonding position detection system detects abnormalities. For example, an information processing terminal having a function of collectively collecting abnormal information notifies the operator selection system 100 that the bonding accuracy has deteriorated.

Once notified that a situation to be dealt with has occurred, the operator selects the system 100, and based on the notified information, obtains the operation information of the operation related to the situation from the operation information storage unit 102 storing information about the necessary operation in the equipment. An example of job information is shown in Figure 4. The operator selects the job classification unit 110 of the system 100, performs classification judgment of the job based on the acquired job information, and identifies the content of the job to be handled (S302).

For example, if it is notified that the lamination accuracy has deteriorated, the operator selects the system 100, and obtains the cause of the state from the operation information storage unit 120, the basis for determining the necessary operation, the necessary operation, the time required for the operation, Information such as the time when the work was performed (refer to Figure 4). The job classification unit 110, based on the information and the sensing data from each part of the equipment P, recognizes that 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 necessary work is "replacement of the bonding roller". The work classification unit 110 can also identify the time required for the work or the time when the work should be performed, as necessary.

In addition, the classification judgment of the target task is ideally performed by the operator selecting the system 100, for example, by using a predetermined abnormal code or the data shown in FIG. 4 to be automatically performed, but for example, when it is notified that the lamination accuracy has deteriorated At this time, the operator can also determine the cause based on various sensing data, past experience, work manuals, etc., and identify the necessary work, and the content of the identified work can be given to the operator to select the system 100 from the input unit to proceed. In addition, for example, when an unset situation such as an abnormal code occurs, the operator selection system 100 can also be designed to determine the operation content by analogy from the information stored in the operation information storage unit 120.

Then, once the operation to be handled is identified, the operator selects the system 100, and for the plural operators involved in the operation of the equipment P that can handle the operation, it will include information about the operator and information about the operation performed by the operator in the past The operator information of is obtained from the operator information memory 104 storing the information. Once the operator selection system 100 obtains the operator information, the operation inexperienced person determining unit 112 determines whether there is an inexperienced person for the operation identified in S302 (S303). When there is no inexperienced person, the operator selects the system 100, and then, based on the operator information of a plurality of operators, obtains the information about the operation skill for the task from the operation skill information memory unit 106 storing this information, that is, Job skill information.

Operational skills refer to the ability of the operators in the equipment to perform the operations when certain operations on the equipment are necessary. There are no particular limitations on the index that expresses the job skill as long as it can show the ability of the operator to perform the job, and various indexes are conceivable. Operational skills, ideally, are quantitative indicators, but they can also be qualitative indicators. When using qualitative indicators as work skills, it is better to design the system to automatically convert the indicators into a certain numerical value. In the operator selection system 100 according to the present invention, it is preferable to use a quantitative value representing each operator's ability to perform tasks as a task skill.

As work skills, for example, it is possible to use the average of the time required for the work in the past, the shortest work time among the time required for the work in the past, the number of times the work was performed in the past, and the movement distance during the work. / Numerical values such as travel time. FIG. 5A illustrates an example in which the shortest work time among the time required to deal with the work in the past is set as the work skill. Fig. 5(a) is an example when the work to be handled is a simple work. In this example, operator A is a highly skilled operator and operator D is a low-skilled operator. In addition, FIG. 5(b) is an example when the work to be handled is a difficult work. In this example, the operator I is a high-skilled worker, and the operator J is a low-skilled worker.

Or, 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. 5B illustrates an example of setting the value obtained by weighting the skill level value as the work skill. Fig. 5B is based on the skill level value assigned to each job based on another evaluation (for example, job training sheet, etc.) for each job. From the combination of skills necessary to identify the job that needs to be dealt with in S302, The value of each skill level value is weighted total or averaged and used as the work skill. In the example of FIG. 5B, for example, when the No. 3 job occurs, the skill of each worker is calculated based on the weights in the items of "RTP Basics" and "Quality Abnormal Treatment" in the job training table. The job skill values of Operator A, Operator B, Operator C, and Operator D are 2.4, 3.3, 1.9, and 1.0, respectively. Therefore, the operator with the highest skill is operator B, and the operator with the lowest skill is operator D.

In the following descriptions of this manual, an example is given of using the shortest work time among the work time required by each operator to deal with the work in the past as the work skill. Returning to FIG. 3, it is determined in S303 that there is no inexperienced person, and after obtaining the work skill information of a plurality of operators, the work skill determination unit 116 selects the operator with the lowest work skill. In addition, the processing (S304) for the case where it is determined whether there is an experienced person in S303 will be described later.

Once a low-skilled worker is selected by the work skill judging unit 116, the operator selection unit 124 selects one of the operators as a responder to the task, and outputs the operator information (S305). The output operator information can be displayed, for example, on a portable information terminal owned by each operator, or a monitor installed in the device P. The operators who are output to these information terminals perform necessary operations in response to the situation that occurs in the equipment P (S306).

Once the operation is completed, the responding operator or the manager of the operation, such as from a portable information terminal or an input terminal provided in the device P, inputs the operation completion information including the details of the operation, the operation time, etc. (S307). The operator selects the information update part 126 of the system 100, and once the inputted operation completion information is obtained, it uses this information to update any of the operation information, operator information, and operation skill information stored in the memory, or their Combination (S308). Or, it can also be designed such that the information update unit 126 automatically obtains the start time and end time of the operation, the details of the operation, etc., and uses this information to update the operation information, operator information, and operation skill information stored in the memory. Any one or a combination of them.

The task inexperienced person determination unit 112, when it is determined whether there is an experienced person for the task identified in S302 (S303), the task skill determination unit 116 obtains the assumed task preset for the inexperienced person from the operator information storage unit 104 skill. The information that is set as a hypothetical job skill can be set in response to being used as an index of the job skill. In the case of the present embodiment in which the shortest work time among the time required to deal with the work in the past is used as the work skill, as the assumed work skill of the inexperienced person, it is possible to set the work time when other operators performed the work in the past The longest operation time among them. Or, as a hypothetical work skill, it is also possible to set an average value of the work time of other operators when the work was performed for the first time in the past.

The assumed work skills of the inexperienced person can be set in advance as described above and stored in the work skill information storage unit 106 as work skill information, but it can also be automatically set by the operator selection system 100. In the case of the present embodiment using the shortest time as the work skill, the work inexperienced person judging unit 112 judges whether there is an experienced person for the necessary work. The operator selection system 100 can respond to this and obtain other work from the operator information storage unit 104 The work time when the person performed the work in the past is compared, and the longest work time is set as a hypothetical work skill and stored in the work skill information storage unit 106.

Next, a description will be given of the operator selection process in the case of considering the possibility of improvement in the work skills of the operator who performs the work when selecting the operator who should respond to the work. FIG. 6 illustrates the processing flow 600 in the case where the operator's work skill improvement possibility is considered in the operator selection process. In the following description, the parts that are different from the flow of FIG. 3 are mainly described.

In this system, low-skilled workers are selected as workers who perform the work. Here, if you think about the improvement of the skills of the entire group formed by a plurality of operators, for example, when there are a plurality of operators with the same level of work skills, it is ideal to choose to perform the work Those who are expected to improve their work skills. In view of this, the processing flow 600 is designed to consider the changes in the past work skills of the selected operator in the work, and if it is determined that the work skills can be improved, the operator is maintained, and it is determined that the work skills cannot be improved. In the case of other operators, select other operators.

In step S606 of the process flow 600, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility of the worker selected in S605. The possibility of improvement of work skills can be determined by determining, for example, the change in the work time of the work of the operator in the past (for example, work time involving a plurality of work in the past or work time of the previous work). The work skill improvement possibility judging unit 122 acquires from the work information storage unit 102 the work time of the extracted operator multiple times in the past, compares the work time, and if the work time tends to be shortened every time the work is performed, It is determined that it is possible for the operator to improve the work skills of the work. However, for the operator who is selected as a candidate for the operator for the task for the first time, or the operator who is selected for the second time, there is no information on the assumed task skills or only the previous task skills, so Unable to determine the possibility of improvement in work skills. Therefore, in S606, the first or second job operator will be judged that the job skill of the job may be improved.

On the other hand, the work skill improvement possibility judging unit 122 compares the work time of the extracted operator in the past plural times, and if the work time does not tend to be shortened every time the work is performed, it judges the work time of the worker. The improvement of homework skills is impossible. In this case, the work skill determination unit 116 selects another low-skilled worker with the lowest work skill from among the workers other than the operator (S607, S608, S605). Similarly for this operator, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility.

As a result of repeating the steps of S605 to S608, when it is determined in S608 that there are no remaining candidates for the operator, the operator selection unit 124 will select the responding operator ( S609). The selection method at this time is not particularly limited. For example, it is possible to select the worker with the highest work skill among all the workers, or the worker who is located at the place closest to the place where the work is necessary among all the workers.

Next, it will be explained that when selecting the operator to respond to the task, the possibility of improving the work skill of the worker performing the work is taken into consideration, and if it is determined that the improvement of the work skill is impossible, the design is designed to be highly skilled in the work. The operator is selected under the guidance of the "educator" to make the selected operator (low-skilled operator) perform the task. FIG. 7A illustrates the processing flow 700A. In this process, it is designed to select another operator (low-skilled operator) when the combination of the extracted operator and the educator is the same combination as the previous task that is the same as the task. In the following description, the parts that are different from the processing flow of FIG. 6 are mainly described.

In S706A of the process flow 700A, when the work skill improvement possibility determination unit 122 determines that the worker’s work skill improvement is impossible, the work skill determination unit 122 confirms among a plurality of workers other than the extracted worker Whether there is a person with higher work skills than the operator (S707A), and the highly skilled operator with the highest work skills among the plurality of operators is selected (S708A). The high-skilled workers selected here can become educators of low-skilled workers who are judged to be impossible to upgrade their job skills under a single job. With this educator and low-skilled workers working together, it is hoped to improve the working skills of low-skilled workers.

When the assignments of the last responder and the corresponding operator to be selected here are the same assignments, the combination of operator and educator is the same as the combination selected here, which means that the operator has the same assignment as A combination of educators has done this assignment, but has not grown. In this case, if the same combination is allowed again, assuming that the operator did not grow from this task, the same combination will still be selected for the next same task, and the result may not be achieved by other operators. Skills upgrade. In order to prevent such a problem from occurring, it will be determined whether the combination of the selected operator and educator is the same as the combination used to deal with the same assignment as the previous assignment (S709A). If it is the same combination, the operator will be reselected . If it is not the same combination, proceed to the next processing.

In addition, even if it is determined that it is not the same combination in S709A, when the job skill gap between the combined operator and the educator is small, the educational effect caused by the educator may not be worth expecting. Therefore, in this case, it is better to re-select operators, so as to strive to improve the operating skills of low-skilled operators.

In S711A, the work skill judging unit 116 obtains the work skill gap between the operator and the educator judged to be not the same combination in S709A. In the case of the present embodiment in which the shortest work time among the work time required in the past to respond to the work is used as the work skill, the work skill gap can be set to the difference between the shortest work time of the two. When the difference is greater than or equal to a predetermined value (prescribed standard), it is deemed that the education effect of the educator is worth expecting, and finally the operator selected in S705A and the operator selected as the educator in S708A are selected. The operator selection unit 124 selects both as the responder. In addition, although the determination of S711A is performed after the determination of S709A here, the order of their determination may be reversed.

On the other hand, when the combination of the selected operator and the educator is the same as the combination of the previous assignment that is the same as the assignment, or when the combination of the operator and the educator is found When the job skill gap of is smaller than the predetermined value, the job skill judging unit 116 selects another low-skilled worker with the lowest job skill from among the plurality of workers other than the worker (worker candidate) (S712A , S713A, S705A). Similarly for this operator, the work skill improvement possibility determining unit 122 determines the work skill improvement possibility (S706A). In this case, the candidate candidates for the evaluation in S713A will also include those selected as educators in S708A. When S707A and S708A are processed again, the candidate may be selected as the educator again. educator.

Next, when selecting an operator to respond to the task, another operator selection process in the case of considering the possibility of improving the work skill of the operator performing the task will be described. FIG. 7B illustrates the processing flow 700B. In the processing flow 700A, when the combination of the selected operator and the educator is the same as the combination of the previous task that is the same as the task, another operator (low-skilled operator) is selected, but the processing flow In 700B, it is designed to select another educator (high-skilled worker) when the combination of the selected operator and educator is the same combination. In the following description, the differences from the processing flow 700A of FIG. 7A are described.

In the processing flow 700B, it is determined whether the combination of the selected operator and the educator is the same as the combination of the previous task that is the same as the task (S709B), and if it is not the same combination, the next processing (S711B) ), this is the same as the processing flow 700A, but when it becomes the same combination, the educator is re-selected. In the case of the same combination, remove the educator drawn in S708B from the selection (S710B), and reconfirm whether there is a higher skill than the operator drawn in S705B among the other operators (S707B), and the highly skilled worker with the highest work skills is selected as an educator who is different from the educator originally selected (S708B). These treatments will be repeated until a different combination appears. In this way, it is possible to prevent the problem that the growth of other operators cannot be realized due to the continuous same combination. In addition, although the determination of S711B is performed after the determination of S709B here, as in the case of the processing flow 700A, the order of their determination may be reversed.

Next, the process of selecting an operator in consideration of the time allowed for the execution of the task when selecting an operator to respond to the task will be described. FIG. 8 illustrates the processing flow 800 in the case where the time allowed for the operation is considered in the operator selection processing. In the following description, the parts that are different from the process 300 of FIG. 3 are mainly described.

In the process flow 300 of FIG. 3, when a situation requiring work occurs, the work skills of a plurality of operators are determined for the work, and the operator with the lowest work skill is selected as the operator who performs the work. However, when there are certain situations in which work must be performed, there may be situations where the operation of the equipment P needs to be stopped, and the production of goods will stop during the period of the operation stop. Therefore, when an operator with low work skills completes the work, it will take time and there is a possibility that the required production volume may not be achieved. The operator cannot be allowed to perform the work, but must be able to take a shorter time The operator who performs the job performs the job. In view of this, the processing flow 800 is designed to compare the allowable time that can achieve the necessary production plan even if the operation of the equipment P is stopped, and the operation time necessary for the extracted operator to perform the operation to determine the operator Whether the work can be completed within the allowable time, if the operator’s work time exceeds the allowable time (allowable stop time for the work), another operator will be selected.

In step S803 of the process flow 800, when it is determined that there is no inexperienced person for the work identified in S802, the operator selects the work allowable time calculation unit 118 of the system 100 and calculates the allowable time for the work (S805). In addition, the calculation of the allowable time is not limited to being performed at this point in time. For example, it may be calculated after the operator with the lowest work skill is selected in S806.

Fig. 9 shows an example of a consideration method for calculating the allowable time. In FIG. 9, the horizontal axis represents time, and the vertical axis represents the production volume of articles. For example, when it is assumed that the operation of the equipment is stopped at the time when the necessary work occurs in the equipment, and the production is restarted after a certain stop time, then if the production can be carried out in the same state as the production before the stop, the production deadline is In the case where the production plan can be achieved in the past, the certain stop time can be set as the "allowable time". The allowable time can be even longer if the production performance so far exceeds the production volume specified in the production plan when the job occurs. In addition, the time calculated as the allowable time, for example, is set based on the expected change in production volume after restarting the work relative to the change in production volume before the start of the work, the estimated production safety level, and the relative The production capacity of the equipment varies with conditions such as the degree of margin in the production plan.

For example, the allowable time calculated based on the consideration method shown in FIG. 9 is passed to the work completion possibility judging unit 120, and the work completion possibility judging unit 120 calculates the shortest work time for the work of the low-skilled worker extracted in S806 Compare with the allowable time (S807). As a result of the comparison, when the shortest work time is shorter than the allowable time, the work completion possibility determination unit 120 determines that the low-skilled worker can complete the work, and the operator selection unit 124 selects the low-skilled worker as a response to the work The responder.

On the other hand, as a result of comparing the allowable time with the shortest work time for the task of the low-skilled worker (S807), when the shortest work time is more than the allowable time, the work completion possibility determination unit 120 determines that the operator cannot Complete the job within the allowed time. In this case, the work skill determination unit 116 selects another low-skilled worker with the lowest work skill from among the workers other than the operator (S808, S809, S806). Similarly for this operator, the work completion possibility determination unit 120 compares the allowable time with the shortest work time (S807).

As a result of repeating the steps from S806 to S809, when it is determined in S809 that there are no job candidates left, in order to complete the job in the shortest possible time, the operator selection unit 124 will select the shortest job time among all operators The operator of is regarded as the operator responding to the operation (S810).

Next, when selecting a worker to respond to the job, the process of selecting the worker taking into consideration the time allowed to perform the job and the possibility of improving the job skill of the worker performing the job will be described. FIG. 10 illustrates the processing flow 1000 in the case where the allowable time of the work and the possibility of improvement of the work skill are simultaneously considered in the operator selection process. In the following description, the parts that are different from the processing flow 800 of FIG. 8 are mainly described.

In step S1007 of the process flow 1000, when it is determined that the selected low-skilled worker can complete the job within the allowable time, then the work skill improvement possibility determining unit 122 determines that the low-skilled worker's work skill improvement is possible Sex (S1008). The way of considering the possibility of improvement in work skills is as described above in the description of the processing flow 600 in FIG. 6. When it is determined in S1008 that the work skill of the low-skilled worker is likely to be improved, the work skill determination unit 116 extracts the low-skilled worker, and the operator selection unit 124 selects the selected low-skilled worker as a response to the work. Responding to the operator.

On the other hand, when it is determined in step S1007 that the low-skilled worker cannot complete the job, or when it is determined in S1008 that the worker’s job skills are not improved to be impossible, the job skill determining unit 116 determines whether the job Among other operators except this operator, another low-skilled operator with the lowest work skills is selected (S1009, S1010, S1006). Similarly for this operator, the work completion possibility determining unit 120 determines the work completion possibility, and the work skill improvement possibility determining unit 122 determines the work skill improvement possibility.

In addition, in the processing flow 1000, for the low-skilled workers extracted in S1006, the possibility of completion of the work is determined in S1007, and the possibility of improvement of the work skill is determined in S1008, but the order of these determinations may be reversed.

Next, it will be explained that when selecting an operator for the task, the time allowed to perform the task and the possibility of improving the skills of the operator performing the task are considered, and it is determined that it is possible to complete the task within the allowed time. In the case where it is impossible to improve the work skills, it is designed to make the selected operators (low-skilled operators) perform the work under the guidance of the "educators" who have high work skills. The person selected for processing. FIG. 11A illustrates the processing flow 1100A. In this process, it is designed to select another operator (low-skilled operator) when the combination of the extracted operator and the educator is the same combination as the previous task that is the same as the task. In the following description, the parts that are different from the processing flow 700A of FIG. 7A are mainly described.

In the processing flow 700A of FIG. 7A, for the selected low-skilled workers, the possibility of improving the job skills of the job is determined. In the processing flow 1100A, before determining the possibility of improvement in the work skills of the extracted low-skilled worker, it is determined whether the worker can complete the work within the allowable time (S1107A). The allowable time is calculated in S1105A. The way to consider the allowable time and the processing when it is determined that the operator cannot complete the job within the allowable time has been described in the processing flow 800 of FIG. 8.

When it is determined in S1107A that the operator can complete the work within the allowable time, it is then determined that the operator's work skill can be improved (S1108A). When it is determined that it is possible to improve the work skills, the operator is selected as the responder. However, when it is determined that the improvement of the work skill is impossible, the work skill determination unit 122 confirms whether there is a worker with a higher work skill than the worker among a plurality of workers other than the selected operator (S1109A), The high-skilled worker with the highest job skills among the multiple workers is selected, and this worker is designated as an educator who is judged to be an impossible job under a single job. The processing of S1109A to S1115A in this case is the same as the processing of S707A to S713A in the processing flow 700A of FIG. 7A.

As a result of comparing the allowable time in S1107A with the minimum work time for the task of a low-skilled worker, when the minimum work time is more than the allowable time, the work completion possibility judging unit 120 determines that the operator cannot complete the work within the allowable time operation. In this case, the work skill determination unit 116 selects another low-skilled worker with the lowest work skill among the workers other than the operator (S1114A, S1115A, S1106A). For this operator, compare the allowable time and the shortest operating time in the same way (A1107A).

As a result of repeating the steps from S1106A to S1115A, when it is determined in S1115A that there is no candidate for the operator, in order to complete the operation in the shortest possible time, the operator selection unit 124 will select the shortest operation time among all operators The operator of is regarded as the operator responding to the task (S1116A).

Next, when selecting an operator to respond to the task, another operator selection process will be described in consideration of the time allowed to perform the task and the possibility of improvement in the work skills of the operator performing the task. FIG. 11B illustrates the processing flow 1100B. In the processing flow 1100A, when the combination of the selected operator and the educator is the same as the combination of the previous task that is the same as the task, another operator (low-skilled operator) is selected, but the processing flow In 1100B, it is designed to select another educator (high-skilled worker) when the combination of the selected operator and educator is the same. In the following description, the difference from the processing flow 1100A of FIG. 11A will be described.

In the processing flow 1100B, it is determined whether the combination of the selected operator and the educator is the same as the combination of the previous task that is the same as the task (S1111B). If it is not the same combination, proceed to the next processing (S1113B) ), this is the same as the processing flow 1100A, but when it becomes the same combination, the educator is re-selected. In the case of the same combination, remove the educator drawn from S1110B from the selection (S1112B), and reconfirm whether there is a higher skill than the operator drawn in S1106B among the other operators (S1109B), and the highly skilled worker with the highest work skills is selected as an educator who is different from the educator who was initially selected (S1110B). These treatments will be repeated until a different combination appears.

As explained in detail above, according to the present invention, not only the working skills of low-skilled persons can be quickly improved, but also the working skills of high-skilled persons can be further improved for various tasks required in the equipment. In addition, it is possible to improve the work skills of the entire work group formed by a plurality of operators involved in the operation of the equipment.
