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 dealt with 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 of the occurrence, and formulate countermeasures for the operation. Among the operations that must be dealt with, when there is an operation that has to stop the production of the article, such as the operation to solve the problem in the equipment or the operation to replace and supplement the material, the time it takes if the operation ends 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, it is conceivable that 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 deal with it, and for difficult tasks that must be dealt with for a long time, then Order the veteran worker with high skill for the job to respond.

When the equipment requires some work that should be handled, the operator who is ordered to handle the work 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 achievements, 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 carried out 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 operator 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 the 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, it will become, for example, that a new operator is always assigned for simple tasks, and a veteran operator is always assigned for difficult tasks. If such assignment continues, it 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 do not improve, it is impossible to expect the improvement of the equipment operation skills of the entire group, or even the further efficiency of the production of goods. 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 task lower. The operator actually experiences the work to improve the thinking way of 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 is improved according to the result of the education can deal with the work 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 efficient education that is closer to the actual situation.

In order to solve the above-mentioned unsolved problems, the purpose of the present invention is to provide an automatic operator selection system in equipment, which is designed to quickly improve the skills of low-skilled operators, and can also improve the number of operators involved in the use of equipment. The skills of all members of the team. [Technical means to solve the problem]

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 used to make the computer system execute each step of the method selected by the operator. [Effects of Invention]

According to the present invention, not only can the work skills of low-skilled persons be quickly improved for various operations necessary in the equipment, but also the work skills of high-skilled persons can be further improved. 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.

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. In the operation information storage unit 102, information about necessary operations in the equipment is stored. In the operator information storage unit 104, the information of the author and the information about the past work of the operator are stored. In the work skill information storage unit 106, information on the work skills of each operator who responds to the work occurring in the equipment is stored. In the production-related information storage unit 108, production-related information of the articles produced by the equipment is stored.

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 the data equivalent to the job skill information and the data equivalent to the operator information are mixed, it is not limited to which hardware is stored collectively, and the data can also be stored in the state of being distributed to multiple hardware In this case, the area storing the data equivalent to the operator information other than the operation skill information is equivalent to the operator information memory unit 104, and the area storing the data equivalent to the operation skill information is equivalent to the operation skill information memory unit 106 .

The operation information memorized in the operation information storage unit 102 is information about 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 containing the status of the equipment, the reason for the status, the basis for determining the necessary operations to deal with the state of the equipment, the content of the necessary operations, the time required for the operation, and the progress 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 storage unit 108, for example, can be set as the production capacity of the device, the production plan of the article (production volume, number of 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, which stores the sensing data made by sensors that monitor the state of each part of the device P. Sensing data, for example, combined with operation information, can be used as data for judging 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 person determination unit 112, a work skill dispersion estimation unit 114, a work skill determination unit 116, a work allowable time calculation unit 118, The 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 one hardware database or as a distributed database. Similarly, the operator selects each functional unit 110-126 of the system 100, which can be constructed in one computer hardware, or in a plurality of scattered computer hardware, and it is configured to perform the functions of the various computer hardware in cooperation with each other. The function.

The operator selection system 100 can be used, for example, in an RTP system device to automatically select an operator who responds to tasks necessary for the operation of the device. The RTP method is a ribbon-shaped optical film laminate supported by a plurality of sheet-shaped optical films on a ribbon-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 sequence, and the adhesive layer is bonded to the rectangular panel to continuously manufacture the liquid crystal display device. The continuous manufacturing system of liquid crystal display devices that realizes this method is called "Roll To Panel (RTP)" device, in order to bond the previously cut optical film sheet to the 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, which can use a memory device such as a central processing unit (CPU), and a 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 also 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 interfaces used to communicate with other computers or networks.

FIG. 3 illustrates a processing flow 300 executed in order to select an operator to perform the operation in the operator selection system 100. For example, in the 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 dealt with 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, the operation of the device must be stopped, and the operator checks the situation, and if necessary, for example, paste The correction of the integrated parameters or the replacement of the feed roller, etc. 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 that should 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 judging the necessary operation, the necessary operation, the time required for the operation, Information such as the time when the operation was performed. The job classification unit 110, based on the information and the sensing data from each part of the device P, recognizes that when the accuracy deterioration is due to the deterioration of the bonding roller, and the replacement of the bonding roller has not been performed for a certain period of time, it is recognized 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 point 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 abnormality code or the data shown in FIG. 4 to be automatically performed, but for example, when notified of deterioration of the lamination accuracy 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 to perform the operations in the equipment 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 express 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 a qualitative index is used as a job skill, it is better to design the system to automatically convert the index 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 value 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 has been performed in the past, and the movement distance during the work. / Numerical values such as travel time. FIG. 7 described later 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.

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. 5 shows an example in which the value obtained by weighting the skill level value is set as the work skill. Figure 5 shows 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, each skill The level value is the value obtained by weighted total or average, and used as the work skill. In the example of FIG. 5, 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 description of this manual, an example is given of using the shortest work time as the work skill among the work time required by each operator in the past to cope with the work. Returning to Fig. 3, it is determined in S303 that there is no inexperienced person, and after obtaining the job skill information of a plurality of operators, the operator selects the system 100, and in the job skill dispersion estimation unit 114, the difference between the plural operators is obtained. The degree of dispersion of work skills (S305). In addition, the processing (S304) in the case where it is determined whether there is an experienced person in S303 will be described later.

Fig. 6 is an example of a situation in which the degree of dispersion of work skills among a plurality of workers is calculated. For example, when the operators A to E are operators who can cope with the work, the work skill dispersion estimating unit 114 obtains the shortest work time of the work in the past for all the operators. Find the difference (same as (3)) between the shortest time ((1) in Figure 6) and the longest time (same as (2)) among the obtained shortest work time (same as (3)), and divide the difference by the shortest work time (same as (4)) ), thereby obtaining the degree of dispersion of the work skills of the workers A to E in the job. In the case of the example in Fig. 6, the degree of dispersion of the work skills is calculated as "2.0".

Next, the operator selects the work skill determination unit 116 of the system 100, and compares the degree of dispersion estimated by the work skill dispersion degree estimation unit 114 with a predetermined reference value related to the degree of dispersion (S306). When it is determined that the degree of dispersion of work skills is greater than or equal to the predetermined standard, the work skill determination unit 116 selects the operator with the lowest work skill (Yes in S306). On the other hand, when it is determined that the degree of dispersion of work skills is smaller than the predetermined criterion, the work skill determination unit 116 selects the worker with the highest work skill (No in S306).

FIG. 7 illustrates an example of selecting one of a low-skilled worker and a high-skilled worker according to the degree of dispersion of work skills. Figs. 7(a) and (b) are examples of cases where the work to be dealt with are simple work, and Figs. 7(c) and (d) are examples of cases where the work to be dealt with is difficult work. For example, when the operation of the equipment is started, when there is a gap in the work level between the operators of the work, a simple work that should be handled occurs (the situation in FIG. 7(a)). When the task occurs during the period (initial) when the number of occurrences of the task is high, and the degree of dispersion of the task skills is calculated as 2.0, if the prescribed standard is set as 1.0, the selected operator will become Operator E (ie, low-skilled operator). When the operation of the equipment continues, and the same operation occurs at a certain point in time (mid-term and later) when the number of occurrences of the operation gradually decreases, the degree of dispersion of the operation skills will be calculated in the same way. The degree of dispersion is calculated as 9.0 and 2.0, so Operator E will be drawn out.

Here, the predetermined standard is set arbitrarily, but as an example, the predetermined standard can be set by the following considerations. That is, the predetermined standard is set to 1.0, and when the degree of dispersion calculated in S305 is 1.0 or more, the working time of highly skilled workers (the shortest time) and the working time of low-skilled workers (the longest time) There is a gap of more than 2 times between ), so I want to improve the work skills of low-skilled workers. On the other hand, when the degree of dispersion is less than 1.0, it is considered that there is no significant gap in the work skills between the operators, and it is desired to seek further improvement in the skills of highly skilled operators.

At the start of the operation of the equipment, when there is no difference in the work level between the operators of the work, the simple work that should be handled occurs (the situation in Figure 7(b)), the same calculation and Judging, each of the early and mid-stages will select operator A or operator B (i.e. high-skilled operators), and in the later stage, operator E (i.e. low-skilled operators) will be selected. When a difficult operation that should be dealt with occurs, no matter when there is a difference in the work level between the operators of the work at the start of the operation of the equipment (the situation in Figure 7 (c)) and the situation where there is no difference in the work level (Figure 7 ( In the case of d), low-skilled workers or high-skilled workers are appropriately selected at various points in time according to the degree of dispersion.

Returning to FIG. 3, once a low-skilled worker or a high-skilled worker is selected by the operation skill determination unit 116, the operator selection unit 124 selects one of the operators as the responding operator for the task, and outputs the operator information (S307 or S308). 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 operator who is output to these information terminals performs necessary operations in response to the situation that occurs in the equipment P (S309).

Once the operation is completed, the responding operator or the manager of the operation, for example, 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. (S310). The operator selects the information update unit 126 of the system 100, and once the inputted operation completion information is obtained, the information is used to update any of the operation information, operator information, and operation skill information stored in the memory, or any of them as necessary. Combine (S311). 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 judging unit 112, when judging whether there is an experienced person for the task identified in S302 (S303), the task skill dispersion degree estimating unit 114 obtains the pre-set for the inexperienced person from the operator information storage unit 104 Assume homework skills. 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. For example, when 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 longest work time among other operators in the past when the work was performed Time of the job. 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. For example, when the shortest time is used as the work skill, the work inexperienced person determination unit 112 determines whether there is an experienced person for the necessary work. The operator selection system 100 can respond to this and obtain other operators from the operator information memory unit 104. The work time when the work is performed 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, 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 flow of FIG. 3 are mainly described.

In the processing flow 300 of FIG. 3, when a situation that requires work occurs, the degree of dispersion of the work skills of a plurality of operators is calculated for the work, and when the degree of dispersion is greater than a predetermined standard, the lowest work skill The operator is selected as the operator who performs the task. However, when there are certain situations where work must be performed, there may be situations where the operation of the equipment P needs to be stopped, and the production of the article will be stopped 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 perform the work in 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 required to 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 S808.

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 condition as the production before the stop, the production deadline is In the case that 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 longer if the production results so far exceed 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 task of the low-skilled worker extracted in S808 Compare with the allowable time (S810). 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 (S810), when the shortest work time is more than the allowable time, the work completion possibility judging unit 120 judges that the worker cannot Complete the job within the allowed time. In this case, the work skill determination unit 116 selects the operator with the lowest work skill from among the plurality of operators except for the operator (S811, S812, S808). Similarly for this operator, the work completion possibility judging unit 120 compares the allowable time and the shortest work time.

As a result of repeating the steps from S808 to S812, when it is determined in S812 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 (S813).

In S807 and S808, the case where the low-skilled worker is extracted is as described above, but even when the high-skilled worker is extracted, the same processing is performed (S807, S809, S814 to S817).

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 is to respond to the work. FIG. 10 illustrates the processing flow 1000 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, the degree of dispersion of the work skills of a plurality of operators is calculated, and when the degree of dispersion is greater than a predetermined standard, a low-skilled operator is selected as the operator to perform the task. Here, if we 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 do the work by making them do the work. Those who are expected to improve their work skills. In view of this, the processing flow 1000 is designed to consider the changes in the work skills of the extracted operators in the work in the past, 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 this case, other operators are selected.

In step S1009 of the process 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 improvement in 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 obtains the work time of the extracted operator from the work information storage unit 102 and compares the work time. 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.

On the other hand, the work skill improvement possibility judging unit 122 compares the multiple work time of the extracted operator in the past, 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 the operator with the lowest work skill from among the plurality of operators except for the operator (S1010, S1011, S1007). 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 from S1007 to S1011, when it is determined in S1011 that there are no job candidates left, the operator selection unit 124 will select the operator with the highest job skill among all the operators as the responder for the job (S1012 ).

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

Next, when selecting an operator to respond to the task, the process of selecting the operator 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 will be described. FIG. 11 illustrates the processing flow 1100 in the case where the allowable time of the work and the possibility of improving the skill of the work are considered in the process of selecting the operator at the same time. In the following description, the parts that are different from the flow of FIG. 3 are mainly described.

In step S1103 of the processing flow 1100, when it is determined that there is no inexperienced person for the work identified in S1102, the operator selects the work allowable time calculation unit 118 of the system 100, and calculates the work allowable time in S1105. The calculation of the work 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 in S1108 is selected. The calculation method of the work allowable time is as described above 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. Regarding the possibility of improvement in work skills, it is as described above in the description of the processing flow 1000 in FIG. 10. The work skill improvement possibility judging unit 122 obtains the work time of the extracted operator from the work information storage unit 102 and compares the work time. If the work time tends to be shortened every time the work is performed, It is determined that the operator has a high possibility of improving the work skills of the work.

Next, in step S1111, the work completion possibility determining unit 120 compares the shortest work time of the work with the work allowable time with respect to the low-skilled worker whose work skill is determined to be highly likely to be improved in S1110. As a result of the comparison, when the shortest work time is shorter than the work 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 respondent of the job.

When it is determined in step S1110 that the improvement of the operator’s work skills is impossible, or when it is determined in S1111 that the low-skilled operator cannot complete the work, the work skill determination unit 116 removes the work skill among the plurality of operators. Among the other operators of the operators, the operator with the lowest work skills is selected (S1112, S1113, S1108). Similarly for this operator, the work skill improvement possibility determination unit 122 determines the possibility of work skill improvement, and the work completion possibility determination unit 120 determines the work completion possibility.

In addition, in the processing flow 1100, for the low-skilled workers extracted in S1108, the possibility of improvement of the work skills is determined in S1110, and the possibility of completion of the work is determined in S1111, but the order of these determinations may be reversed.

As a result of repeating the steps from S1108 to S1113, when it is determined in S1113 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 worker of is regarded as the responding worker who responds to the job (S1114).

In S1007 and S1008, the case when the low-skilled worker is extracted is as described above, but even when the high-skilled worker is extracted, the same processing is performed (S1107, S1109, S1115 to S1119).

FIG. 12 illustrates a specific example of the improvement of work skills in the case where the operator selection processing flow 1110 shown in FIG. 11 is executed. Figure 12 (a) is a specific example of the improvement of work skills for simple tasks (that is, tasks that take a short time to perform the work), and Figure 12 (b) is for more complex tasks (that is, those that take a long time to perform the work). Homework) specific examples of the improvement of work skills. Either way, it is assumed that one of the five operators A to E will perform the assignment, and the shortest work time of the assignment is set as the work skill.

For the first operation in Figure 12(a), the operation time of Operator A or Operator B with the shortest operation time (set the initial setting to 5 minutes) and the operation time of Operator E with the longest operation time (set the The initial setting value is set to 15 minutes) to calculate the degree of dispersion of work skills, it becomes "2.0" as shown in the column of (4). If the predetermined reference value is set to 1.0, the degree of dispersion is greater than or equal to the predetermined reference value, and therefore the operator E is extracted. For the extracted operator E, compare the shortest work time (15 minutes) with the work allowable time (100 minutes) calculated based on the consideration method shown in FIG. 9, for example, to determine that the operator E can complete the work within the work allowable time, Therefore, the operator E (newcomer) is selected as the responder for the task. As a result of the work performed by the operator E, assuming that the work is completed in 12 minutes, the minimum work time of the work by the operator E is updated to 12 minutes.

When the second job occurs, it is judged that the degree of dispersion is greater than the prescribed reference value. Even the operator E with the longest job time can complete the job within the job allowable time. Moreover, the operator E is in the first One operation is completed in a shorter time (12 minutes) than the initial set shortest operation time (15 minutes). Therefore, it is judged that there is also a possibility of improvement in operation skills. Therefore, here, the operator E will be selected as the responding operator. In the same way when the third and fourth operations occur, operator D and operator C are selected as responders.

When the fifth job occurs, use the job time (5 minutes) of operator A or B with the shortest job time (5 minutes) and the job time of operator E (9 minutes) with the longest job time to calculate the degree of dispersion of job skills the size of. The degree of dispersion becomes "0.8", which is a value smaller than the predetermined reference value, so here, operator A or operator B will be extracted. These operators are judged to complete the assignment in the shortest work time, so here operator A or operator B is selected as the operator to perform the assignment. In addition, regarding which of the operator A and the operator B should be finally selected as the responding operator, it is ideal to follow the judgment result of the possibility of improvement of the work skills, but when the possibility of growth is the same (Figure 12(a) In the example of ), the past work time transitions of both are the same), and can be selected using other arbitrary standards. Here, it is assumed that the operator A (veteran) is selected as the responder.

Hereinafter, when the 6th to 10th tasks occur, the responders are selected in the same way. In this way, the operators are selected in order from the 10 assignments. By this, the skills of the operator E who originally had low work skills will be improved, and as a result, the skills of the entire group can also be improved.

To illustrate the example shown in FIG. 12(b), first, when the first job occurs, the degree of dispersion of job skills is calculated as described above. The degree of dispersion is "0.7", so if the predetermined reference value is set to 1.0, the operator A with the highest work skill is selected. The minimum work time of this operator is set to 60 minutes, which is shorter than the allowable work time of 95 minutes. Therefore, it is judged that the operator will finish the work within time, and operator A (veteran) is selected as the responder.

Next, when the second job occurs, the degree of dispersion of the job skills is 1.0 or more, so the worker E with the lowest job skill is selected. However, for the operator E, the minimum work time of the work is set to 100 minutes, which is longer than the work allowable time of 95 minutes, so it is judged that the operator E will not complete the work within the work allowable time. In this case, the operator with the lowest work skills among the other operators except operator E, that is, operator D, is selected as the responder (in addition, for the basis for selecting operator D among operator C and operator D, It is assumed that it can be based on arbitrary benchmarks). In the following, when the third to seventh tasks occur, the responders are selected in the same way.

When the eighth job occurs, the degree of dispersion is 0.9, and the shortest time of the job of the operator A is within the job allowable time, so the operator A should be extracted. However, the operator A was selected as the respondent for the 7th work as a result of the work performed, and there is no effect of shortening the work time, so it is judged that the improvement of work skills is impossible. Therefore, here, for the remaining operators B to E, the degree of dispersion and the possibility of completion of the work are determined, and as a result, the operator B is selected as the responding operator. In this way, the operators are selected in order from the 10 operations. By this, not only the operators C to E, but also the work skills of operators A and B will be improved, and the results will be improved. Improve the skills of the entire group.

As described in detail above, according to the present invention, not only the working skills of low-skilled people can be quickly improved, but also the working skills of high-skilled people can be further improved for various operations necessary 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.
