Description

Worker selection system, worker selection method, and worker selection computer program

The present invention relates to a system for automatically selecting a worker corresponding to a required work in equipment, and more specifically, a worker who should handle the work based on work skill information of a plurality of workers. A system for selecting workers automatically.

In the production facility of goods, various operations that need to be handled may occur during the operation of the facility. The work that needs to be dealt with is not only the work that can be performed without stopping the production of the article, but also the work that cannot be performed without stopping the production. When work that requires a response occurs, the location of the work must be searched, the cause of the work must be investigated, and measures must be taken to carry out the work. Among the work that requires measures, work that requires the production of goods to be stopped, for example, work to solve problems that occur in equipment, work to replace or replenish materials, etc. If the time to finish is long, the production of goods will not be carried out as planned, it will not be possible to produce the quantity and quality of goods required by the required date, and equipment and workers will not operate to achieve the production plan. There is a risk of overwork.

In the production facility of goods, multiple workers often form a team to operate the facility. In a team consisting of a plurality of workers, normally, experienced workers who have high skills in operations required to operate equipment, to low-skilled new workers who have little experience are arranged in a well-balanced manner. Even if the same work can be completed by a veteran worker in a short time and with high precision, a new worker often takes time or has low precision. Further, even the same worker has some work that he or she is familiar with, and some work that has little experience. When a work that requires handling occurs in equipment, a worker who handles the work is selected in consideration of various situations. For example, if it is a simple task that can be dealt with in a short time, it is suitable for new workers and workers with low skills for that task, and for difficult tasks that require long-term support, skills for that task are required. It is conceivable to deal with highly experienced workers.

Patent Document 1 is proposed as a technique proposed from the viewpoint of automatically selecting a worker to handle the work when some work to be performed in the facility is required and providing appropriate training to the worker. There is one disclosed in Patent Document 4.
Patent Document 1 relates to a worker education system for educating workers in a short period of time in planning a production line and appropriately allocating workers having appropriate skill levels to the line. This system searches for workers with an appropriate skill level based on the skill that indicates the standardized proficiency level for each work process on the production line, places them on the line, and determines the skill rank of each worker. You can then carry out training when you need it. Training is based on a schedule provided by educational tools and systems that allow workers to self-learn.

Patent Document 2 reflects the skill level of the worker, the arrangement status of the worker in the work process, and the educational achievement of the worker in real time, and by enabling these data to be grasped in a unified manner, the production efficiency can be improved. The present invention relates to a support system capable of improving and supporting a training plan for workers. In this system, the skill level of the worker is evaluated from the manufacturing record and the educational record, and the personnel is assigned in consideration of the skill level. The system extracts any workers who have not reached the skill level and creates an education plan for the workers. Education for low-skilled workers is planned for non-working hours that are not allocated to work processes.

Patent Document 3 is capable of automatically extracting an appropriate worker in a product manufacturing line so that the worker can perform the work, and at the same time, having the worker receive an appropriate education at an appropriate time. It is related to the system to improve the skill of workers. In this system, when a new work is performed, based on the processing level including one of accuracy and speed when the worker engages in the work and the performance level of the test the worker took, It is possible to select a worker who has an appropriate skill to engage in the work.

Patent Document 4 relates to a system that allows workers to be assigned to projects in consideration of changes in the skills of workers when creating project execution plans for maintenance work and engineering work. In this system, the worker is calculated based on the standard estimated work time according to the skill level of the worker for each work in the workflow that constitutes the project and the actual work time of the worker in charge of each work that has already been performed. It is possible to calculate and update the current skill level of, and calculate the estimated work time of each work based on the updated skill level of the worker assigned to each work.

The system constructed based on the idea proposed in Patent Documents 1 to 4 should appropriately perform the work based on the skill of each worker when the work requiring the handling occurs in the equipment. It is intended to automatically select a worker who can do the work. However, when workers are selected by these systems when work occurs, for example, new workers are always assigned to simple work, and veteran workers are always assigned to difficult work. However, there is a problem that it is difficult to improve the work skills of new workers early if they are continuously assigned. Moreover, in general, multiple operators work in teams to operate equipment, but if the skills of low-skilled workers do not improve, the equipment operation skills of the entire team cannot be expected to improve. It becomes difficult to further improve the efficiency of product production.

Further, in the systems proposed in Patent Documents 1 to 3, although the education for improving the skill of the worker is taken into consideration, in any of the techniques, the worker who has a low skill for the work is required to perform the work. It does not adopt the idea of improving skills through actual experience. The worker education implemented in these systems is conducted separately from the operation of the equipment, and as a result of the education, the workers whose skill level has improved can cope with the work according to the skill level. is there. Therefore, it is desirable to provide an opportunity for a new worker to deal with difficult work that occurs during actual facility operation so that more efficient education according to the actual situation can be provided.

In order to solve the above problems, the present invention makes it possible to improve the skills of low-skill workers at an early stage and also improve the skills of the entire team consisting of multiple workers involved in the operation of equipment. The purpose is to provide an automatic worker selection system for equipment.

A storage unit that stores work skill information that is information about work skills of a plurality of workers for the work. The storage unit can also store the production related information of the articles produced by the facility.

The worker selection system includes a work skill variation calculation unit, a work skill determination unit, a worker selection unit, and an information updating unit. The work skill variation calculation unit acquires work information, worker information, and work skill information from the storage unit when a work that needs to be handled occurs, and the work skill variation calculation unit obtains the work skill variation of a plurality of workers for the work. Find the size. The work skill determination unit extracts the worker having the lowest work skill when the variation is equal to or larger than a predetermined standard, and the worker having the highest work skill when the variation is smaller than the predetermined standard. To extract. The worker selecting unit selects the extracted worker as a worker who responds to the work, and outputs worker information of the worker. The information updating unit updates one or a combination of the work information, the worker information, and the worker skill information in the storage unit, based on the result of the work performed by the corresponding worker selected by the worker selecting unit. To do.

In one embodiment, the worker selection system acquires the production-related information from the storage unit, and calculates the allowable time for which the production plan can be achieved even when the operation of the equipment is stopped to perform the work. A time calculation unit and a work completion possibility determination unit that determines whether the worker extracted by the work skill determination unit can complete the work within the allowable time may be provided. . Furthermore, the worker selection system obtains a change in past work skill of the worker for the worker extracted by the work skill determination unit and determines a work skill improvement possibility based on the change. It is also possible to further include a skill improvement possibility determination unit. Furthermore, the worker selection system determines whether or not there is a worker who has no experience in performing the work among the plurality of workers, and if there is the worker, the worker has a temporary work skill for the work. It is also possible to further include a work inexperienced person determination unit for setting.

The second aspect of the present invention provides a worker selection method for automatically selecting a worker corresponding to a required work in a facility from a plurality of workers. In a third aspect of the present invention, there is provided a computer program executable on a computer system, which includes instructions for causing the computer system to execute each step of the worker selection method.

According to the present invention, not only can the work skills of low-skilled workers be improved early on, but also high-skilled workers can further improve the work skills of various works required in equipment. Further, it is possible to improve the work skills of the entire work team including a plurality of workers who operate the equipment.

An embodiment of a worker selection system according to the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of a worker selection system 100 according to an embodiment of the present invention. The worker selection system 100 receives a notification (work occurrence notification) that a work requiring handling has occurred in the equipment P, and outputs information on a worker who should handle the work (corresponding worker information). And includes a functional unit that executes various judgments and calculations based on the information of the work occurrence notification, and a storage unit that stores various information used for executing the function.

The worker selection system 100 includes a work information storage unit 102, a worker information storage unit 104, a work skill information storage unit 106, and a production related information storage unit 108. The work information storage unit 102 stores information about necessary work in the facility. The worker information storage unit 104 stores information about the worker and information about the past work of the worker. The work skill information storage unit 106 stores information about the work skill of each worker corresponding to the work that occurs in the facility. The production-related information storage unit 108 stores production-related information of articles produced by the equipment.

Regarding the information stored in each storage unit, the work information, worker information, work skill information, and production-related information do not have to be physically aggregated. For example, the data corresponding to the work skill information and the data corresponding to the worker information are mixed and are not limited to being collectively stored in any of the hardware. The work information may be stored in a distributed manner in the wear, and in that case, the area in which data corresponding to the worker information other than the work skill information is stored corresponds to the work information storage unit 104. An area in which data corresponding to is stored corresponds to the work skill information storage unit 106.

The work information stored in the work information storage unit 102 is information regarding necessary work in the facility, and can be information as shown in FIG. 4, for example. The information shown in FIG. 4 includes, for example, the state of the equipment, the cause of the state, the basis for determining the work required to respond to the state of the equipment, the content of the required work, the time required for the work, and the work. It is a table that includes the timing to perform.

The worker information stored in the worker information storage unit 104 includes information on a worker who can engage in necessary work in the facility and information on the past work of the worker. The worker information includes, for example, the name of the worker, the ID number, the department to which the worker belongs, the details of the work performed by the worker in the past, the time required to respond to the work, the date and time when the work was performed, It includes the results of the work done.

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

The production-related information of the article stored in the production-related information storage unit 108 includes, for example, the production capacity of the device, the production plan of the article (production amount, number of production days, production deadline, production safety level, production margin, etc.), article Can be the production record of

The worker selection system 100 preferably further includes a sensing data storage unit 109 that stores sensing data from a sensor or the like that monitors the state of each part of the facility P. The sensing data is used together with work information, for example, and can be used as data for determining necessary work.

As shown in FIG. 1, the worker selection system 100 includes a work classification unit 110, a work inexperienced person determination unit 112, a work skill variation calculation unit 114, a work skill determination unit 116, a work allowable time calculation unit 118, and work completion. It may include a sex determination unit 120, a work skill improvement possibility determination unit 122, a worker selection unit 124, and an information updating unit 126. The function of each of the functional units 110 to 126 will be sequentially described below.

The storage units 102 to 109 may be configured as one hardware database or a distributed database. Similarly, each of the functional units 110 to 126 of the worker selection system 100 may be built in one computer hardware, or may be built in a plurality of distributed computer hardware, and each of the computer units. It may be configured so that the functions of the respective parts are exhibited by the cooperation of the hardware.

The worker selection system 100 can be used, for example, in an RTP type device to automatically select a worker corresponding to a work required when operating the device. The RTP method is a normal sheet having no defects from a belt-shaped optical film laminate in which a plurality of sheet-shaped optical films are supported on a belt-shaped release film via an adhesive layer in a manufacturing process of a liquid crystal display device or the like. This is a method for continuously manufacturing a liquid crystal display device by sequentially peeling only the functional film together with the pressure-sensitive adhesive layer from the release film and adhering it to the rectangular panel via the pressure-sensitive adhesive layer. A continuous manufacturing system for liquid crystal display devices that realizes such a method is distinguished from a device that realizes a conventional individual bonding method in which a sheet of an optical film that has been cut out in advance is bonded to a rectangular panel, and is referred to as “continuous bonding (RTP;・ Panel) ”device.

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

FIG. 3 shows a processing flow 300 executed by the worker selection system 100 to select a worker to perform a work. For example, when some event requiring work occurs in the equipment P such as an RTP device, the equipment P notifies the worker selection system 100 that an event to be dealt with has occurred (S301). The occurrence of an event to be dealt with in the facility P can be detected by various measuring instruments such as sensors attached to a plurality of locations in the facility P, for example. For example, in an RTP device, when the accuracy of the bonding position of the optical film deteriorates in the process of bonding the optical film to the liquid crystal panel, the operator stops the operation of the device and the operator searches for the situation and Accordingly, for example, it is necessary to correct the bonding parameters and replace the feed roller. In such a case, the bonding position detection system detects an abnormality, and, for example, the bonding accuracy is deteriorated with respect to the worker selection system 100 from an information processing terminal having a function of collecting abnormality information in a unified manner. You will be notified that you have done it.

When notified that an event to be handled has occurred, the worker selection system 100 stores the work information of the work related to the event and the information about the necessary work in the facility based on the notified information. Acquired from the work information storage unit 102. An example of the work information is as shown in FIG. The work classification unit 110 of the worker selection system 100 performs work classification determination based on the acquired work information, and specifies the work content to be handled (S302).

For example, when notified that the bonding accuracy has deteriorated, the worker selection system 100 causes the work information storage unit 120 to cause the situation, a basis for determining necessary work, necessary work, and work. Acquire information such as the time required for work and the timing of work. In the work classification unit 110, based on these pieces of information and the sensing data from each part of the equipment P, the cause of the accuracy deterioration is deterioration of the bonding roller, and the bonding roller has not been replaced for a certain period of time. Specifies that the required work is "replacement of the laminating roller". The work classification unit 110 can also specify the time required for the work and the timing at which the work should be performed, if necessary.

Note that it is desirable that the classification determination of the target work is automatically performed by the worker selection system 100, for example, by using a predetermined abnormality code or the data shown in FIG. When a notification is given, the operator judges the cause based on various sensing data, past experience, work manual, etc., specifies the necessary work, and selects the specified work content from the input section. It can also be done by giving to the system 100. Further, for example, when an event in which an abnormal code or the like is not set occurs, the worker selection system 100 may determine the work content by analogy with the information stored in the work information storage unit 120.

Next, when the work to be handled is specified, the worker selection system 100 is involved in the operation of the equipment P, and the worker information and the worker information about a plurality of workers who can handle the work. Worker information including information on work performed in the past is acquired from the worker information storage unit 104 in which these pieces of information are stored. When the worker selection system 100 acquires the worker information, the work inexperienced person determination unit 112 determines whether or not there is an inexperienced person for the work specified in S302 (S303). If there is no inexperienced person, the worker selection system 100 then stores work skill information, which is information about work skills corresponding to the work, based on the worker information of the plurality of workers. It is acquired from the created work skill information storage unit 106.

The work skill is the work performance capability of the worker who performs the work at the facility when some work related to the facility is required. The index indicating the work skill is not particularly limited as long as it can represent the ability of the worker to perform the work, and various indexes can be considered. The work skill is preferably a quantitative index, but may be a qualitative index. When a qualitative index is used as the work skill, it is preferable that the system can automatically use a value obtained by converting the index into some numerical value. In the worker selection system 100 according to the present invention, it is preferable to use a quantitative value representing the work performance of each worker as the work skill.

As the work skill, for example, the average value of the time required for the work in the past when dealing with the work, the shortest work time of the time required when responding to the work in the past, the work performed in the past Numerical values such as the number of times and the moving distance / moving time when performing the work can be used. FIG. 7, which will be described later, shows an example in which the shortest work time of the times required to deal with the work in the past is used as the work skill.

Alternatively, as the work skill, it is possible to use the accuracy of the result of performing the work in the past or a value calculated based on the skill level separately determined. FIG. 5 shows an example in which a value obtained by weighting skill level values and summing them is used as a work skill. FIG. 5 shows the skills required to perform the work identified as requiring a response, using the skill level value given based on a separate evaluation (for example, a work training table) for each worker for each work. The value obtained by weighting the respective skill level values from the combination of and summing or averaging is used as the work skill. In the example of FIG. When the work of No. 3 occurs, the skill of each worker is calculated based on the weights in the items of “RTP basics” and “quality abnormality treatment” in the work training table. The work skill values of the worker A, the worker B, the worker C, and the worker D are 2.4, 3.3, 1.9, and 1.0, respectively. Therefore, the worker with the highest skill is the worker B, and the worker with the lowest skill is the worker D.

In the following description of this specification, an example will be described in which each worker uses the shortest work time among the work times required to deal with the work in the past as work skill. Returning to FIG. 3, after it is determined in S303 that there is no inexperienced person, and the work skill information of the plurality of workers is acquired, the worker selection system 100 causes the work skill variation calculation unit 114 to perform the operation among the plurality of workers. The size of the variation in work skills is calculated (S305). The process (S304) when it is determined in S303 that there is an inexperienced person will be described later.

FIG. 6 is an example of the case of calculating the degree of variation in work skills among a plurality of workers. For example, when the workers A to E are workers who can handle the work, the work skill variation calculation unit 114 acquires the shortest work time in the past work of all the workers. Of the acquired minimum work time, the difference (same (3)) between the shortest time ((1) in FIG. 6) and the longest time (same (2)) is obtained, and the difference is divided by the shortest work time (same (4). )), The size of the variation in the work skills of the workers A to E in the work is obtained. In the case of the example in FIG. 6, the magnitude of the variation in work skills is calculated as “2.0”.

Next, the work skill determination unit 116 of the worker selection system 100 compares the size of the variation calculated by the work skill variation calculation unit 114 with a predetermined reference value regarding the size of the variation (S306). When it is determined that the degree of variation in work skills is equal to or greater than the predetermined reference, the work skill determination unit 116 extracts the worker having the lowest work skill (Yes in S306). On the other hand, when it is determined that the variation of the work skill is smaller than the predetermined reference, the work skill determination unit 116 extracts the worker having the highest work skill (No in S306).

FIG. 7 shows an example of a pattern in which either a low-skill worker or a high-skill worker is selected according to the degree of variation in work skills. 7 (a) and 7 (b) are examples where the work to be handled is a simple work, and FIGS. 7 (c) and 7 (d) are examples where the work to be handled are difficult. . For example, when there is a difference in the work level between the workers of the work at the time of starting the operation of the facility, an example will be described when a simple work to be performed (case of FIG. 7A). When the work occurs at a time when the number of occurrences of the work is large (initial stage) and the magnitude of the variation in the work skill is calculated to be 2.0, assuming that the predetermined criterion is 1.0, the extracted workers are It becomes the worker E (that is, the low skill worker). When the same work occurs at any time (middle term and latter term) when the operation of the equipment continues and the number of occurrences of the work gradually decreases, the variation of the work skill is calculated in the same manner, and the variation is 9.0. Since it was calculated as 2.0, the worker E is extracted in each case.

Here, the predetermined standard is arbitrarily set, but as an example, the predetermined standard can be set according to the following concept. That is, when the predetermined criterion is 1.0 and the variation calculated in S305 is 1.0 or more, the working time of the high skill worker (shortest time) and the working time of the low skill worker (longest time) Since there will be a more than double difference with the time), the work skill of low skill workers will be improved. On the other hand, if the magnitude of the variation is less than 1.0, it is considered that there is no great difference in the work skills among the workers, and the skill of highly skilled workers is further improved.

In a case where there is no difference in the work level between the workers of the work at the time of starting the operation of the equipment, when a simple work to be performed (case of FIG. 7B) occurs, the same calculation and judgment are performed. Thus, the worker A or the worker B (that is, the high skill worker) is extracted in each of the initial and middle periods, and the worker E (that is, the low skill worker) is extracted in the latter period. When a difficult work to be handled occurs, when there is a difference in the work level between the workers of the work at the start of operation of the equipment (case of FIG. 7C) and when there is no difference in the work level (see FIG. Also in the case of 7 (d)), a low skill worker or a high skill worker is appropriately extracted at each time point according to the magnitude of the variation.

Returning to FIG. 3, when the low skill worker or the high skill worker is extracted by the work skill determining unit 116, the worker selecting unit 124 selects any worker as a corresponding worker corresponding to the work. Then, the worker information is output (S307 or S308). The output worker information can be displayed on, for example, a portable information terminal held by each worker or a monitor provided in the facility P. The worker output to these information terminals performs necessary work in response to the event that occurred in the equipment P (S309).

When the work is completed, the corresponding worker who performed the work or the manager thereof inputs work completion information including details of the work, work time, etc. from, for example, a portable information terminal or an input terminal provided in the facility P ( S310). When the information updating unit 126 of the worker selection system 100 acquires the input work completion information, any one of the work information, the worker information, and the work skill information stored in the storage unit, or these, is used by using this information. The combination is updated as needed (S311). Alternatively, the information updating unit 126 automatically acquires the start time and end time of the work, details of the work, and the like, and uses these information to store the work information, the worker information, and the work skill stored in the storage unit. Any of the information or a combination thereof may be updated.

When the work inexperienced person determination unit 112 determines that there is an inexperienced person for the work specified in S302 (S303), the work skill variation calculation unit 114 uses the temporary work skill set in advance for the inexperienced person. It is acquired from the person information storage unit 104. The information set as the temporary work skill can be set according to the index used as the work skill. For example, when the shortest work time of the time required to deal with the work in the past is used as the work skill, the temporary work skill of the inexperienced person is used by another worker in the past. It is possible to set the longest working time of the working time when performing. Alternatively, as the temporary work skill, it is possible to set the average value of the work time when another worker first performed the work in the past.

The temporary work skill of an inexperienced person can be set in advance as described above and stored as work skill information in the work skill information storage unit 106, but the worker selection system 100 automatically sets it. You can also For example, when the shortest time is used as the work skill, in response to the work inexperienced person determination unit 112 determining that there is an inexperienced person for the required work, the worker selection system 100 changes the worker information. It is possible to acquire the work time when another worker has performed the work in the past from the storage unit 104, compare the work times, set the longest work time as a temporary work skill, and store it in the work skill information storage unit 106. .

Next, when selecting the worker who corresponds to the work, the worker selection process when considering the time allowed for performing the work will be described. FIG. 8 shows a processing flow 800 in the case where the time allowed for work is taken into consideration in the worker selection processing. In the following description, parts different from the flow of FIG. 3 will be mainly described.

In the process flow 300 of FIG. 3, when an event requiring a work occurs, the work skill variations of a plurality of workers for the work are calculated, and when the magnitude of the variation is equal to or larger than a predetermined reference, the work skill The lowest worker is extracted as the worker who performs the work. However, when some event that requires work occurs, it may be necessary to stop the operation of the facility P, and the production of goods is stopped while the operation is stopped. Therefore, if it is possible that a worker with low work skills will not achieve the required production amount because it takes time to complete the work, he or she may not be allowed to perform the work. Instead, it is necessary to let an operator who can perform the work in a shorter time perform the work. Therefore, in the processing flow 800, the allowable time that can achieve the required production plan even when the operation of the equipment P is stopped is compared with the working time required for the extracted worker to perform the work. Then, the worker determines whether or not the work can be completed within the allowable time, and the working time of the worker exceeds the allowable time (allowable stop time for performing the work). Try to extract another worker.

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

Figure 9 shows an example of how to calculate the allowable time. In FIG. 9, the horizontal axis represents time and the vertical axis represents the production amount of the article. For example, when the required work occurs in the equipment, the operation of the equipment is stopped, the production is restarted after a certain stop time, and if the production is performed in the same situation as before the production is stopped, the production will be completed by the production deadline When it is assumed that the plan can be achieved, the certain stop time can be set as the “allowable time”. The allowable time can be made longer if the production record up to that time exceeds the production amount specified in the production plan when the work occurs. Also, the time calculated as the allowable time is, for example, how much the expected transition of the production amount after the work is restarted is set with respect to the transition of the production amount before the work is started, and how much the safety level of the production is expected. However, it will change depending on conditions such as how much margin the production plan has with respect to the production capacity of the facility.

For example, the allowable time calculated based on the concept shown in FIG. 9 is passed to the work completion possibility determination unit 120, and the work completion possibility determination unit 120 performs the relevant work of the low skill worker extracted in S808. The shortest working time and the allowable time are compared (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 skill worker can complete the work, and the worker selection unit 124 The low skill worker is selected as a corresponding worker corresponding to the work.

On the other hand, when the allowable time is compared with the shortest work time of the low-skill worker for the work (S810), if the shortest work time is equal to or longer than the allowable time, the work completion possibility determination unit 120 causes the worker Then, it is judged that the work cannot be completed within the allowable time. In this case, the work skill determination unit 116 extracts the worker having the lowest work skill from among the workers other than the worker among the plurality of workers (S811, S812, S808). Similarly for this worker, the work completion possibility determination unit 120 compares the allowable time with the shortest work time.

As a result of repeating the steps from S808 to S812, when it is determined in S812 that no work candidate remains, the worker selecting unit 124 sets the work selection unit 124 to complete the work in the shortest possible time. The worker having the shortest work time among all the workers is selected as a corresponding worker for the work (S813).

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

Next, we will explain the worker selection process when considering the possibility of improving the work skills of the workers who carry out the work when selecting the workers who will handle the work. FIG. 10 shows a processing flow 1000 in the case of considering the possibility of improving the work skill of the worker in the worker selection process. In the following description, parts different from the flow of FIG. 3 will be mainly described.

In this system, variations in work skills of multiple workers are calculated, and if the magnitude of the variations is equal to or greater than a predetermined standard, low-skill workers are selected as workers who perform the work. Here, considering the improvement of the skill of the entire team composed of a plurality of workers, for example, when there are a plurality of workers having the same work skill, the work skill can be expected to be improved by performing the work. It is desirable to select a worker. Therefore, in the processing flow 1000, when it is determined that the work skill can be improved in consideration of the change in the work skill of the extracted worker in the work in the past, the worker is directly extracted and the work is extracted. If it is determined that skill improvement is not possible, another worker is selected.

In step S1009 of the processing flow 1000, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility of the worker selected in step S1007. The possibility of improving the work skill can be determined by, for example, obtaining a change in the work time of the work in the past by the worker (for example, the work time over a plurality of past works or the work time of the previous work). it can. The work skill improvement possibility determination unit 122 acquires the past work times of the extracted worker a plurality of times from the work information storage unit 102, compares the work times, and shortens the work time each time the work is performed. If there is a tendency, it is determined that the work skill of the worker concerned can be improved.

On the other hand, the work skill improvement possibility determination unit 122 compares the extracted work times of the past multiple times of the worker, and if there is no tendency for the work time to be shortened for each work execution, the work skill improvement possibility It is determined that work skills cannot be improved. In this case, the work skill determination unit 116 extracts the worker having the lowest work skill from among the plurality of workers excluding the worker (S1010, S1011, S1007). Similarly, for this worker, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility.

As a result of repeating the steps from S1007 to S1011, when it is determined in S1011 that no work candidate remains, the worker selecting unit 124 selects the worker having the highest work skill among all the workers. A corresponding worker corresponding to the work is selected (S1012).

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

Next, a description will be given of a worker selection process in the case of selecting a worker corresponding to a work, in consideration of a time allowed for performing the work and a possibility of improving the work skill of a worker performing the work. . FIG. 11 shows a processing flow 1100 in the case of considering both the work allowable time and the work skill improvement possibility in the worker selection processing. In the following description, parts different from the flow of FIG. 3 will be mainly described.

In step S1103 of the process flow 1100, when it is determined that there is no inexperienced person for the work specified in S1102, the work allowable time calculation unit 118 of the worker selection system 100 calculates the work allowable time in S1105. The work allowable time is not limited to be calculated at this time, and may be calculated after the worker having the lowest work skill is extracted in S1108, for example. The concept of calculating the work allowable time is described above in the description of the processing flow 800 of FIG.

Next, in step S1110, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility of the worker selected in step S1108. The work skill improvement possibility has been described above in the description of the processing flow 1000 in FIG. 10. The work skill improvement possibility determination unit 122 acquires the past work times of the extracted worker a plurality of times from the work information storage unit 102, compares the work times, and shortens the work time each time the work is performed. If there is a tendency, it is determined that there is a high possibility that the worker will improve the work skill of the work.

Next, in step S1111, the work completion possibility determination unit 120 compares the shortest work time of the work with the work allowable time for the low skill worker determined to have a high possibility of improving the work skill in step 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 skill worker can complete the work, and the worker selection unit 124 determines , The low skill worker is selected as a corresponding worker corresponding to the work.

When it is determined in step S1110 that the work skill of the worker cannot be improved, or when it is determined in S1111 that the low skill worker cannot finish the work, the work skill determination unit 116 Of the plurality of workers, the worker having the lowest work skill is extracted from the other workers except the worker (S1112, S1113, S1108). Similarly, for this worker, the work skill improvement possibility determination unit 122 determines the work skill improvement possibility, and the work completion possibility determination unit 120 determines the work completion possibility.

In the process flow 1100, the work skill improvement possibility is determined in S1110 and the work completion possibility is determined in S1111 for the low skill worker extracted in S1108. The order may be reversed.

As a result of repeating the steps from S1108 to S1113, when it is determined in S1113 that no work candidate remains, the worker selecting unit 124 sets the work to be completed in the shortest possible time. A worker having the shortest work time among all the workers is selected as a corresponding worker corresponding to the work (S1114).

The above is the case when the low work skill worker is extracted in S1007 and S1008, but the same process is performed when the high skill worker is extracted (S1107, S1109, S1115 to S1119).

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

Regarding the first work shown in FIG. 12A, the work time of the worker A or the worker B having the shortest work time (the initial set value is 5 minutes) and the work time of the worker E having the longest work time (the original work time) The setting value is set to 15 minutes), and the magnitude of the work skill variation is calculated to be "2.0" as shown in the column (4). If the predetermined reference value is set to 1.0, the magnitude of the variation is equal to or larger than the predetermined reference value, and thus the worker E is extracted. For the extracted worker E, when the shortest work time (15 minutes) is compared with the work allowable time (100 minutes) calculated based on the concept of FIG. 9, for example, the worker E is within the work allowable time. Since it is determined that the work can be completed, the worker E (new employee) is selected here as the corresponding worker who performs the work. If the worker E finishes the work in 12 minutes as a result of performing the work, the shortest work time of the work of the worker E is updated to 12 minutes.

When the second work is performed, it is determined that even the worker E having the longest work time, whose magnitude of variation is larger than the predetermined reference value, can finish the work within the work allowable time. It is judged that there is a possibility that the work skill may be improved because the first work was completed in a time (12 minutes) shorter than the initially set minimum work time (15 minutes). Selected as a response worker. Similarly, when the third and fourth work occurs, the worker D and the worker C are selected as corresponding workers, respectively.

When the fifth work occurs, the work skill of the worker A or the worker B having the shortest work time (5 minutes) and the work time of the longest worker E (9 minutes) are used. The magnitude of the variation of is calculated. The magnitude of the variation is “0.8”, which is a value smaller than the predetermined reference value. Therefore, the worker A or the worker B is extracted here. Since it is determined that these workers can finish the work within the shortest work time, the worker A or the worker B is selected as the worker who performs the work here. Note that it is desirable to follow the judgment result of the work skill improvement possibility as to which one of the worker A and the worker B is finally selected as the corresponding worker, but when the growth possibility is about the same (FIG. 12). In the example of (a), both past work time transitions are the same), and other arbitrary criteria can be used for selection. Here, it is assumed that the worker A (experienced worker) is selected as the corresponding worker.

Hereafter, when the 6th to 10th work occurs, the corresponding worker is also selected. In this way, by sequentially selecting the workers in the ten times of work, the skill of the worker E having low work skill is improved, and as a result, the skill of the entire team can be improved.

Explaining the example shown in FIG. 12 (b), first, when the first work occurs, the size of the variation in work skills is calculated in the same manner as above. Since the magnitude of the variation is “0.7”, if the predetermined reference value is set to 1.0, the worker A having the highest work skill is extracted. The minimum work time of this worker is set to 60 minutes, which is shorter than the work allowable time of 95 minutes. Therefore, it is determined that this worker can finish the work in time, and the worker A (experienced worker) is the corresponding worker. Is selected as

Next, when the second work occurs, the variation of the work skill is 1.0 or more, so the worker E having the lowest work skill is selected. However, since the minimum work time of the worker E is set to 100 minutes, which is longer than the work allowable time 95 minutes, it is determined that the worker E cannot finish the work within the work allowable time. In this case, among the other workers except the worker E, the worker D having the lowest work skill is selected as the corresponding worker (note that among the workers C and D, the work is performed). The basis for selecting the person D can be based on arbitrary criteria). In the case where the third to seventh work occurs, the corresponding worker is similarly selected.

When the eighth operation occurs, the variation is 0.9 and the minimum work time of the worker A is within the work allowable time. Therefore, the worker A should be extracted. However, as a result of the worker A being selected as a worker corresponding to the seventh work and performing the work, there is no effect of shortening the work time, and thus it is determined that the work skill cannot be improved. Therefore, here, with respect to the remaining workers B to E, the degree of variation and the work completion possibility are determined, and as a result, the worker B is selected as the corresponding worker. In this way, by sequentially selecting the workers in the ten times of work, the work skills of not only the workers C to E who have low work skills but also the workers A and B are improved, and as a result, The skills of the entire team can also be improved.

As described above in detail, according to the present invention, not only can the work skills of low-skilled workers be improved at an early stage, but also the high-skilled workers can further improve the work skills of various works required in equipment. Can be made. Further, it is possible to improve the work skills of the entire work team including a plurality of workers who operate the equipment.
