(Embodiment)
<Configuration: Production system 1>
A configuration of the production system 1 according to the present embodiment will be described.

FIG. 1 is a block diagram showing a production system 1 according to an embodiment. FIG. 2 is a schematic explanatory diagram showing the production system 1 in the embodiment.

As shown in FIGS. 1 and 2, in the production system 1, workers and work supervisors perform various works on the floor of the production site. Hereinafter, in this embodiment, unless otherwise specified, the operator will be mainly described. A work supervisor is a person who has the authority to supervise a worker's work. In this embodiment, the work performed by the worker is work before and during production. During production is the time during production planning for executing the production plan at the production site. For example, during production, the power supply to the mounting line 40 is ON, the off-line work setup, in-line work, splicing work, etc., the period in which the mounting line 40 is in operation (the period in which the mounting line 40 is temporarily stopped is also included). including), etc. On the other hand, "pre-production" means, for example, the state before the mounting line is put into operation before the day's production starts on the floor of the production site.

The work performed by the worker includes, for example, the following work.

For example, the operator performs splicing work, parts supply work to the autoload feeder, feeder placement work, soldering work, empty tape box cleaning work, recognition error handling work, adsorption error handling work, and transport error handling. Work such as work is performed on the production floor.

The splicing work is a work for splicing a tape on a new reel to a tape on an old reel, which has been supplied with stored components and which has little left, and continuing to supply components from the old reel using the new reel. Specifically, the operator cuts off the leading end of the tape on the new reel and the trailing end of the tape on the old reel with scissors. Then, the worker brings the tape tip of the new reel and the trailing edge of the tape of the old reel into contact with each other at the above-mentioned break, and affixes the affixing tape to join them together.

The work of supplying components to the auto load feeder is the work of supplying reel tape to the auto load feeder attached to the production apparatus. Specifically, the worker cuts the leading end of the tape on the reel up to the portion where the components are stored. Next, the operator operates a switch for opening the shutter of the tape insertion port of the autoload feeder to open the shutter, and inserts the tape of the reel with the tip cut off into the tape insertion port. Then, when the setting of the tape is completed, the operator operates a switch for starting the automatic feeding of the tape to start the automatic feeding.

The feeder placement work is the work of attaching the tape feeder to the production device. Specifically, the worker attaches the tape feeder to a cart attached to the production apparatus. Then, the worker attaches the reel to the cart on which the tape feeder is attached.

The solder leveling work is a work of stirring solder used in a screen printing device or the like. Since solder is stored in a refrigerator or the like and becomes hard, it is necessary to stir the solder taken out of the refrigerator or the like before use. The operator stirs the solder for about 5-10 minutes, depending on the type of solder, to achieve good softness.

Empty tape box cleaning work is work for cleaning an empty tape box that is attached to a cart that is attached to a production apparatus and stores empty tape that has been emptied after components have been supplied. Specifically, the worker removes the empty tape box in which the empty tape is accumulated from the cart and discards the empty tape to clean the empty tape box. Then, the worker attaches the cleaned empty tape box to the cart.

Recognition error handling work is work to be performed when a recognition error occurs in a camera provided in a production apparatus. For example, a recognition error occurs when a part photographed by a camera is not in the correct position or orientation in the recognition image, or when the cover glass of the camera is dirty. In such a case, the operator should adjust the position, tilt or setting of the camera, adjust the position or tilt of the nozzle that holds the part, remove dirt from the nozzle, or cover the camera as work to deal with the recognition error. Wipe off the dirt on the glass and correct the data for recognizing the parts. In addition, for example, if the setting of the board recognition mark preset in the production equipment is incorrect, or if the board stop position is misaligned, a recognition error (specifically, the recognition mark of the board error) occurs. In such a case, the operator corrects the setting of the recognition mark or adjusts the position of the substrate as work to deal with the recognition error.

The suction error handling work is work to be performed when a nozzle suction error occurs. For example, when a pick-up error occurs, the operator checks whether the setting of the component pick-up position of the nozzle is correct as work to deal with the pick-up error, and corrects the setting if it is not correct. Further, for example, when a suction error occurs, the operator adjusts the setting of the suction speed to an appropriate speed as a work to deal with the suction error.

The board transfer error handling work is a work performed when a board transfer error occurs. For example, a substrate transport error occurs when the belt transporting the substrate or the guide of the transported substrate is dirty. In such a case, the operator cleans the belt or guide as work to deal with the board transfer error. Further, for example, when the board detection sensor of the conveyor is in the detection state even though the board is not detected, a board transfer error occurs. In such a case, the operator checks whether or not the substrate detection sensor is dirty, and wipes off the dirt if it is, as work to deal with the substrate transfer error.

In this production system 1, in order to improve the workability of the workers, that is, productivity, the work supervisor appropriately improves the work skills of the workers based on the work performed by the workers. It is possible to provide work education, which is the treatment of

In addition, on the floor of the production site, there are provided a monitoring camera 72 for capturing images of the mounting line and the like arranged on the floor, and a worker camera 71 for capturing images of workers' work. For example, the surveillance camera 72 images the floor of the production site. Moreover, the worker camera 71 images the work of the worker. The monitoring camera 72 and the worker camera 71 may be installed on the wall or ceiling of the floor, or may be installed on the workbench where the worker performs confirmation work.

<Action>
The operations of the work management system 20, the work management method, and the program in this embodiment will be described.

[Operation example 1]
First, the operation for allocating work to workers will be described.

FIG. 4 is a flow chart showing the operation when allocating work.

As shown in FIG. 4, the work management system 20 acquires a production plan database, a maintenance plan database, and the like from the upper management system 10. FIG. Specifically, the work allocation unit 25 receives the production plan database, the maintenance plan database, and the like from the upper management system 10 via the notification unit 32 . The work assignment unit 25 determines whether or not there is work to be assigned to the worker (S1). The work allocation unit 25 always makes the determination in step S1.

When the work allocation unit 25 determines that there is no work to be allocated to the worker (NO in S1), the process returns to step S1.

Further, when the work allocation unit 25 determines that there is work to be allocated to the worker in the work management database (YES in S1), the work allocation unit 25 allocates the work to the allocatable worker (S2). In the case of a worker, by applying for the work he/she wants to do, the work allocation unit 25 can allocate the work to the worker.

Specifically, the work allocation unit 25 acquires the skill information management database from the first management storage unit 21 , the work management database from the second management storage unit 22 , and the requested level database from the third management storage unit 23 . Based on the skill information management database, the work assignment unit 25 extracts workers who satisfy the skill level required to perform the work indicated in the required level database. The work allocation unit 25 calculates the number of workers required for each work shown in the work management database according to the extracted skill level of each worker. For example, the task allocation unit 25 determines that n workers with skill level a are required for task A, and n+α workers are required for task A with skill level b. Here, n and α are natural numbers of 1 or more. The work allocation unit 25 allocates the work shown in the work management database to each worker according to the determined number of workers so as not to cause excess or deficiency.

Note that the work allocation unit 25 may allocate appropriate work to workers who satisfy the skill level required to perform the work shown in the required level database.

The work assignment unit 25 associates the worker with the content of the work assigned to the worker, and updates the work management database in the third management storage unit 23 to update the work management database in the third management storage unit 23. memorize

When the work allocation unit 25 allocates work to the workers, the instruction information generation unit 26 generates instruction information, which is information for instructing the workers assigned by the work allocation unit 25 to perform the work. The instruction information generation unit 26 transmits the generated work instruction information to the manager terminal 60 and the worker terminal 50 via the notification unit 32 .

After allocating the work to the worker in step S2, the work allocation unit 25 determines whether or not there is work left to be allocated to the worker (S3).

When the work assignment unit 25 determines that there is work left to be assigned to the worker (YES in S3), the work management system 20 returns the process to step S1. Since there are a plurality of tasks indicated in the requirement level database, optimum task allocation may be performed so that the tasks indicated in the requirement level database are operated with the minimum number of people.

When the work allocation unit 25 determines that there is no work left to be allocated to the worker (NO in S3), the work management system 20 ends the processing of FIG.

[Operation example 2]
Next, the operation after the work training is given to the worker until the work training is completed will be described. In this operation example, it is assumed that the work is performed before production, but the work may be performed during production.

As shown in FIG. 2, the work management system 20 acquires work event information from the mounting line 40, the worker terminal 50, the worker camera 71, etc. (S10), and constantly monitors the worker's work (S11 ).

When the work event information is acquired via the notification unit 32 (S12), the work determination unit 27 of the work management system 20 determines whether inappropriate work has occurred by the worker based on the work event information. .

When the work determination unit 27 determines that inappropriate work has occurred, it notifies the manager terminal 60 of the occurrence of the inappropriate work via the notification unit 32 (S13). At this time, the work determination unit 27 also transmits information regarding the worker who caused the inappropriate work to the manager terminal 60 via the notification unit 32 .

The display unit 61 of the administrator terminal 60 associates and displays the fact that the inappropriate work has occurred and the information regarding the worker, which is acquired via the communication unit 63 . The manager determines whether or not to request work training for the worker indicated in the information about the worker displayed on the display unit 61 of the manager terminal 60 . For example, if the work of the worker indicated in the work event information is inappropriate, the manager requests work training to the worker who performed the inappropriate work. When the manager determines that work training should be performed for the worker indicated in the information, the manager inputs By inputting, the input unit 62 transmits the setting of the work training request to the work management system 20 via the communication unit 63 (S14). At this time, the skill management unit 31 rewrites and updates the skill information of the worker who performed the inappropriate work in the skill information management database. Specifically, the skill management unit 31 lowers the value of the skill information of the work (eg medium→low).

The work training determination unit 29 of the work management system 20 receives the setting of the work training request, determines that work training is necessary for the worker who performed the inappropriate work, and determines that the worker who performed the inappropriate work needs work training. Execution of work training is set for the worker (S15). At this time, the work training determination unit 29 notifies the worker terminal 50 via the notification unit 32 that work training is required for the worker.

In addition, in order to have the worker who performed the inappropriate work receive work training, the manager inputs to the input unit 62 of the manager terminal 60 , and the input unit 62 sends the work training request via the communication unit 63 . is transmitted to the operator terminal 50 (S16).

As a result, the worker who performed the inappropriate work receives work training from the work supervisor (S17). At this time, the work training management unit 30 manages the progress of work training given to the worker who performed the inappropriate work. For example, the work training management unit 30 manages the progress of work training by acquiring work event information of a worker receiving work training via the notification unit 32 .

When the work training for the worker who performed the inappropriate work is completed, the manager terminal 60 acquires a completion notification from at least one of the worker and the work supervisor. That is, when at least one of the worker and the work supervisor inputs completion of work training to the input unit 52 of the worker terminal 50 , the input unit 52 sends the work instruction to the manager terminal 60 via the communication unit 53 . An education completion notification is sent (S18). When the manager terminal 60 receives the work training completion notification, the manager inputs to the input unit 62 of the manager terminal 60, and the input unit 62 receives the work training completion notification via the communication unit 63. A completion request is sent to the work management system 20 (S19).

The work training management unit 30 determines that work training has been completed by receiving a completion request as a completion notification from at least one of the worker and the work supervisor via the notification unit 32 (S20). In the present embodiment, the work training management unit 30 determines that work training has been completed by receiving a completion request as a completion notification from each of the worker and the work supervisor via the manager terminal 60 .

When the work training management unit 30 determines that the work training for the worker has been completed, the skill management unit 31 of the work management system 20 updates the worker's skill in the work corresponding to the work training, thereby improving the worker's skill. set. For example, the skill management unit 31 resets the worker's skill to the initial value (eg, low→medium) for the work corresponding to the work training given to the worker. In this way, since the worker's skill is improved by receiving the work training, the worker can perform the work related to the work training.

<Effect>
Effects of the work management system 20, the work management method, and the program according to the embodiment will be described.

As described above, the work management system 20 according to the present embodiment performs work, which is a measure for improving the work skill of a worker based on the work event information of the worker working at the production site. A work training determination unit 29 that determines whether or not training is necessary, and a notification unit 32 that notifies the worker that work training is necessary based on the determination result of the work training determination unit 29 .

According to this, it is possible to identify a worker who needs work training by determining whether or not work training is necessary for the worker based on the work event information. Then, the work management system 20 instructs or encourages the worker to receive work training by notifying the worker who needs work training that work training is required. can be done.

Therefore, the work management system 20 can suppress variations in work at the production site by specifying the worker who made the mistake and giving instructions for work training.

Further, in the work management method according to the present embodiment, work event information of a worker working at a production site is acquired, and based on the acquired work event information, it is determined whether or not work training is necessary for the worker. , based on the determination result, notifies the operator that work training is required.

This work management method also has the same effects as those described above.

Also, the program in the present embodiment is a program for causing a computer to execute the work management method.

This program also has the same effects as described above.

In addition, in the work management system 20 according to the present embodiment, the notification unit 32 notifies at least one of the worker and the worker's work supervisor that work training is required.

According to this, since the worker can recognize that the work he or she has done is inappropriate, the worker will be conscious of receiving work training. As a result, workers can improve their own skills by receiving work training, so that variations in work at the production site can be further suppressed.

Further, the work management system 20 in the present embodiment further includes a skill management section 31 that manages the worker's skill from work event information by the worker. Then, the skill management unit 31 sets the worker's skill based on the result of work training by the worker.

According to this, since the skill management unit 31 manages the skill of the worker, for example, if the skill of the worker does not satisfy the skill required for a specific work, the work that does not satisfy the skill required for the work can be made to prevent workers from Therefore, it is possible to suppress a decrease in work efficiency at the production site.

Moreover, since the skill management unit 31 can manage the completion of the work training, the skill can be set when the work training is completed.

In addition, the skill management unit 31 manages the worker's skill, so that the worker can perform work according to his or her own skill. Therefore, it is possible to further suppress variations in work at the production site.

Further, the work management system 20 in the present embodiment further includes a work training management section 30 that manages the progress of work training. Then, the work training management unit 30 determines that work training has been completed based on a completion notification from at least one of the worker and the work supervisor.

According to this, the work training management unit 30 can recognize the work proficiency level (work skill) of the worker by managing the progress of the work training for the worker.

In addition, since the work training management unit 30 can recognize the completion of work training by acquiring a completion notice, for example, it is possible to reset the worker's skill in the work for which work training has been completed. As a result, the work management system 20 allows the worker to perform the work for which work training has been completed. Therefore, it is possible to further suppress variations in work at the production site.

(Modification 1 of Embodiment)
<Configuration: Production system 1>
The configuration of the production system 1 in this modified example will be described.

Below, as shown in FIG. 5, the basic configuration of the production system 1 in this modification is the same as the basic configuration of the production system 1 of the embodiment. A description of the basic configuration will be omitted as appropriate. This modification is different from the embodiment in that the work management system 20a includes a work limit setting unit 28 that limits the work of the worker, mainly assuming the case during production. FIG. 5 is a block diagram showing the production system 1 in Modification 1 of the embodiment.

The work management system 20a of this modified example determines the appropriateness of the work performed by the worker based on the work event information acquired during production. For example, a notice to the effect that education should be given is given. Here, the restriction means restricting the work of the worker so that the worker cannot perform a predetermined work. For work restrictions, for example, if the work allocation unit 25 does not allocate work to a worker whose work is limited, or if the worker requests work, the work limit setting unit 28 is required. In some cases, workers who do not have the required skills are not allowed to work.

The work management system 20a of this modification includes a first management storage unit 21, a second management storage unit 22, a third management storage unit 23, a fourth management storage unit 24, a work allocation unit 25, an instruction information generation unit 26, a work In addition to the determination unit 27 , the work training determination unit 29 , the work training management unit 30 , the skill management unit 31 and the notification unit 32 , a work limit setting unit 28 is provided.

When the work determination unit 27 acquires the work event information, based on the success or failure of the worker's work and the time required for the work included in the work event information, an event that requires a work restriction (interlock) occurs. Determine whether or not When the work determination unit 27 determines that the work must be restricted, the work determination unit 27 notifies the worker terminal 50 via the notification unit 32 that an event requiring the work restriction has occurred. The information about the worker includes an identifier, which is information for identifying the worker, and the details of the work and the number of times an event requiring work restriction has occurred.

The work restriction setting section 28 of the work management system 20a is an interlock control section that restricts the work of the worker based on the work event information. Specifically, if the work of the worker indicated in the work event information is inappropriate, the administrator can issue work lock authentication to the worker who performed the inappropriate work, that is, the worker whose work needs to be restricted. By doing so, the work restriction setting unit 28 restricts the work of the worker. For example, the work limit setting unit 28 determines to limit the work of the worker if the number of times the worker has performed inappropriate work indicated in the work event information or the cumulative failure rate is equal to or greater than a predetermined value. good too. In addition, the work training determination unit 29 restricts the work of the worker even if the time spent on the work is longer than or equal to a predetermined time, or the number of times or ratio of work that has passed the given time or longer is greater than or equal to a predetermined value. Then you can judge.

At this time, the work restriction setting unit 28 notifies the restricted worker of the work restriction via the notification unit 32 . In the present embodiment, the work restriction setting unit 28 notifies the worker terminal 50 whose work is restricted that the work is restricted via the notification unit 32 . Note that the degree or degree of restriction may be appropriately set by the administrator. Here, work lock authentication is authentication performed by the administrator to restrict the work of workers.

Note that the work restriction setting unit 28 may stop the production apparatus so that the worker whose work is restricted cannot work when the worker whose work is restricted tries to work. Further, in this case, the work restriction setting unit 28 notifies, via the notification unit 32, that the worker terminal 50 of the worker whose work is restricted cannot perform the work due to lack of work authorization (skill). good.

Further, the work restriction setting unit 28 releases the work restriction of the worker when the work training given to the worker is completed. For example, the work restriction setting unit 28 removes the restriction on the worker's work when receiving the completion notification of the work training.

In this modified example, this cancellation is performed when the worker and the work supervisor each notify the manager of the completion of the work training. For example, when a worker and a work supervisor work together as part of work training, the completion of work training is notified to the manager by authentication of the two, or the worker reports the work completion to the work supervisor. Then, the supervisor is notified of the completion of the work education by two-stage authentication, such as confirming the details of the work performed by the worker in response to the report. Note that the work training completion notification may be a notification from at least one of the worker and the work supervisor.

The work training determination unit 29 determines whether or not work training is necessary for the worker based on the work event information during production. The work training determination unit 29 acquires the setting of the work training request from the manager terminal 60, and determines that work training is necessary for the worker who performed the inappropriate work, that is, the worker whose work was restricted. Execution of work education is set for workers whose work is restricted. The work training determination unit 29 notifies the worker that work training is necessary via the notification unit 32 during production. In this modification, when the work training determination unit 29 determines that work training is necessary for the worker, the worker whose work is restricted by the work limit setting unit 28 is notified via the notification unit 32. In response, the worker terminal 50 is notified that work training is required.

Also, the notification unit 32 notifies the worker that work training is necessary during production based on the determination result of the work training determination unit 29 . In other words, when the work training determination unit 29 determines that work training is necessary for the worker during production, the notification unit 32 notifies the worker that work training is necessary.

Further, the notification unit 32 notifies the worker whose work is restricted by the work restriction setting unit 28 that the work is restricted. For example, the notification unit 32 may notify the worker that the work has been restricted via the worker terminal 50, or notify the worker that the work has been restricted via the manager terminal 60. good too.

<Action>
The operation of the work management system 20a, the work management method, and the program in this modification will be described. In the operation of this modified example, the operation after the work is restricted to the worker until the work restriction is lifted will be described. In this operation example, it is assumed that work is being performed during production.

FIG. 6 is a flowchart showing an operation in the work management system 20a according to Modification 1 of the embodiment, after the work is restricted to the worker, the work restriction is lifted, and the worker's skill is updated. be.

As shown in FIG. 6, the work management system 20a acquires work event information from the mounting line 40, the worker terminal 50, the worker camera 71, etc., and constantly monitors the worker's work (S21).

When the work event information is acquired via the notification unit 32, the work determination unit 27 of the work management system 20a determines based on the work event information whether or not an event requiring work restriction has occurred (S22). ). Specifically, when the work determination unit 27 acquires work event information from the worker terminal 50, the worker camera 71, and the like via the notification unit 32, the worker's work success or failure included in the work event information is determined. , based on the time taken for the work, it is determined whether or not an event requiring work restriction has occurred. If at least one of the work actually performed by the worker and the time spent on the work is inappropriate, the work determination unit 27 determines that the work needs to be restricted. For example, the work determination unit 27 determines that the work is inappropriate if the number of times the worker has performed inappropriate work indicated in the work event information or the cumulative failure rate is equal to or greater than a predetermined value. In addition, the work determination unit 27 determines that the work is inappropriate even if the time spent on the work is longer than or equal to a predetermined time, or the number of times or ratio of work that has passed the predetermined time or longer is greater than or equal to a predetermined value. judge.

When the work determination unit 27 determines that an event requiring work restriction has not occurred (NO in S22), the process returns to step S21.

When the work determination unit 27 determines that an event requiring work restriction has occurred (YES in S22), the notification unit 32 notifies the user that an event requiring work restriction has occurred and the work and information on the administrator is notified to the administrator terminal 60 (S23).

When the work management system 20a notifies the manager terminal 60 of the fact that an event requiring work restriction has occurred and the information about the worker, the work management system 20a determines the minimum number of personnel required to satisfy the production quality and work plan. If the minimum required number of personnel can be secured, but it is predicted that the important performance indicator will decrease due to the temporary suspension of work, even if this is also notified to the administrator terminal 60 good.

The display unit 61 of the administrator terminal 60 displays information about the worker acquired via the communication unit 63 and the like. The manager determines whether or not to restrict the work of the worker indicated in the information about the worker displayed on the display unit 61 of the manager terminal 60 . For example, if the work of a worker indicated in the work event information is inappropriate, the manager may give The administrator authenticates the work lock. When the manager determines to restrict the work of the worker indicated in the information, the manager inputs work lock authentication to the input unit 62 of the manager terminal 60 in order to restrict the work of the worker. Thus, the input unit 62 transmits the work lock authentication to the work management system 20a via the communication unit 63. FIG. Here, the work lock authentication includes the work and identifier of the worker whose work is to be restricted.

In addition, when receiving the work lock certification via the notification unit 32, the work restriction setting unit 28 of the work management system 20a limits the work of the worker indicated by the work lock certification (S24).

The work restriction setting unit 28 notifies the restricted worker of the work restriction via the notification unit 32 (S25). Specifically, the work restriction setting unit 28 notifies the worker terminal 50 of the worker whose work is restricted that the work is restricted via the notification unit 32 .

Based on the work event information, the work training determination unit 29 determines whether or not work training is necessary for the worker whose work has been restricted, that is, for the worker whose work is restricted (S26). . Specifically, the work training determination unit 29 determines whether or not the work restriction setting unit 28 has received work lock authentication via the notification unit 32, thereby providing work training to the restricted worker. Determine whether education is required.

If the work restriction setting unit 28 has not received the work lock authentication via the notification unit 32, the work training determination unit 29 determines that work training is not necessary for the worker whose work is restricted (S26). NO). In this case, the work management system 20a terminates the processing of FIG.

When the work restriction setting unit 28 receives the work lock authentication via the notification unit 32, the work training determination unit 29 determines that work training is necessary for the worker whose work is restricted (in S26). YES).

In the case of YES in step S26, the work training determination unit 29 notifies the worker determined to require work training through the notification unit 32 that work training is required (S27). That is, in the case of YES in step S26, the work training determination unit 29 notifies the worker terminal 50 of at least one of the worker and the work supervisor via the notification unit 32 that work training is required.

As a result, workers whose work is restricted receive work training from the work supervisor. At this time, the work training management unit 30 manages the progress of work training for the workers whose work is restricted (S28). For example, the work training management unit 30 manages the progress of work training by acquiring work event information of a worker receiving work training via the notification unit 32 .

The work training management unit 30 of the work management system 20a determines whether work training has been completed (S29). Specifically, the work training management unit 30 determines whether or not a work training completion notification has been received from at least one of the worker and the work supervisor.

Specifically, when the work education for the restricted worker is completed, the manager terminal 60 acquires a completion notification from at least one of the worker and the work supervisor. That is, when at least one of the worker and the work supervisor inputs completion of work training to the input unit 52 of the worker terminal 50 , the input unit 52 sends the work instruction to the manager terminal 60 via the communication unit 53 . Send education completion notifications. When the manager terminal 60 receives the work training completion notification, the manager inputs to the input unit 62 of the manager terminal 60, and the input unit 62 receives the work training completion notification via the communication unit 63. A completion request is sent to the work management system 20a. That is, the work training management unit 30 receives a completion request via the notification unit 32, and determines that the work training has been completed by receiving a completion notification from at least one of the worker and the work supervisor.

Accordingly, the work training management unit 30 receives a completion notification from at least one of the worker and the work supervisor via the notification unit 32, and determines that the work training has been completed (YES in S29). In this modification, the work training management unit 30 determines that the work training has been completed by acquiring completion notifications from the worker and the work supervisor. Further, when the work training management unit 30 has not received a completion notification from at least one of the worker and the work supervisor via the notification unit 32, it determines that the work training has not been completed (NO in S29). , the process returns to step S29.

When the work training management section 30 determines that the work training for the restricted worker has been completed, the work restriction setting section 28 releases the work restriction of the worker (S30). The work restriction setting unit 28 notifies the worker terminal 50 via the notification unit 32 that the restriction on the work of the worker has been lifted.

When the work training management unit 30 determines that the work training for the worker has been completed, the skill management unit 31 updates the worker's skill in the work corresponding to the work training (S31), thereby improving the worker's skill. set. For example, the skill management unit 31 restores the worker's skill to the initial value for the work corresponding to the work training given to the worker.

In this way, since the worker's skill is improved by receiving the work training, the worker can perform the work related to the work training.

<Effect>
The effects of the work management system 20a, the work management method, and the program according to this modification will be described.

As described above, the work management system 20a in this modified example further includes the work limit setting unit 28 that limits the work of the worker based on the work event information during production by the worker. Then, the work training determination unit 29 determines that work training is necessary for the worker whose work is restricted by the work limit setting unit 28 .

According to this, it is possible to limit the work during production to workers who need work training. In other words, the work management system 20a can prevent workers who need work training from working. Therefore, it is possible to further suppress variations in work at the production site.

Further, in the work management system 20a according to this modified example, the notification unit 32 notifies the worker whose work is restricted by the work restriction setting unit 28 that the work is restricted.

According to this, the worker can recognize that the work that he/she has done is inappropriate and that the work is restricted, so that he or she will not perform the restricted work. Therefore, it is possible to further suppress variations in work at the production site.

In addition, in the work management system 20a according to this modified example, the work restriction setting unit 28 releases the work restriction of the worker when the work training is completed.

According to this, the work management system 20a can make a worker who has completed the work training perform the work for which the work training has been completed. Therefore, since the worker can work again, it is possible to suppress a decrease in productivity at the production site.

Further, in the work management system 20a in this modified example, the work is work during production. Further, the work training determination unit 29 determines whether or not work training is necessary for the worker based on the work event information during production. Then, the notification unit 32 notifies the worker that work training is necessary during production based on the determination result of the work training determination unit 29 .

According to this, it is possible to identify a worker who needs work training by determining whether or not work training is necessary for the worker based on the work event information during production. In the work management system 20a, even during production, by notifying a worker who needs work training that work training is necessary, work training can be provided to the worker during production. You can direct or encourage to receive. Therefore, it is possible to suppress variations in work at the production site.

This modified example also has the same effects as those described above.

(Modification 2 of Embodiment)
<Configuration: production system 1a>
The configuration of the production system 1a in this modified example will be described.

Below, as shown in FIGS. 7 and 8, the basic configuration of the production system 1a in this modification is the same as the basic configuration of the production system of the embodiment. Description of the basic configuration of 1a is omitted as appropriate. This modification differs from the embodiment in that there is no administrator. FIG. 7 is a block diagram showing a production system 1a in Modification 2 of the embodiment. FIG. 8 is a schematic explanatory diagram showing a production system 1a in Modification 2 of the embodiment.

In this modified example, the production system 1 a includes a host management system 10 , a work management system 20 , a mounting line 40 and an operator terminal 50 .

When the work of the worker indicated in the work event information is inappropriate, the work determination unit 27 of the work management system 20 notifies the occurrence of the inappropriate work and the inappropriate work via the notification unit 32. The worker terminal 50 is notified of the information on the worker who has done the work.

When inappropriate work occurs, the work training determination unit 29 of the work management system 20 determines whether work training is necessary for the worker based on the work event information. When determining that work training is necessary, the work determination unit 27 notifies the worker terminal 50 via the notification unit 32 that an event requiring work training has occurred.

When the work education determination unit 29 determines that work education is required for the worker, the work education determination unit 29 notifies the worker who performed the inappropriate work that work education is required via the notification unit 32. The operator terminal 50 or the like is notified.

Further, the work training management unit 30 of the work management system 20 determines that work training has been completed based on a completion notification from at least one of the worker and the work supervisor. Specifically, when receiving a completion notice from at least one of the worker and the work supervisor, the work training management unit 30 determines that the work training for the worker has been completed.

The notification unit 32 of the work management system 20 performs wire communication or wireless communication with the work management system 20 and the worker terminal 50 via a communication network.

The communication unit 42 of the mounting line 40 performs wired communication or wireless communication with the work management system 20 and the worker terminal 50 via a communication network.

The worker terminal 50 can communicate with the work management system 20 and the upper management system 10 .

<Action>
Operations of the work management system 20, the work management method, and the program in this modified example will be described.

As shown in FIG. 8, work training is given to the worker and the operation until the work training is completed will be described. In this operation example, it is assumed that the work is performed before production, but the work may be performed during production. In this operation example, the same reference numerals are given to the same operations as in the operation example 2 of the embodiment, and the description thereof will be omitted as appropriate.

In the work management system 20, after steps S10 and S11, the work determination unit 27 of the work management system 20 acquires work event information via the notification unit 32 (S12). Determine whether inappropriate work has occurred.

When the work determination unit 27 determines that the inappropriate work has occurred, the work determination unit 27 outputs to the work training determination unit 29 that the inappropriate work has occurred.

The work training determination unit 29 determines whether work training is necessary for the worker based on the work event information. For example, if the number of times the worker has performed inappropriate work indicated in the work event information or the cumulative failure rate is equal to or greater than a predetermined value, the work training determination unit 29 determines that an event requiring work training has occurred. It may be determined that there is In addition, the work training determination unit 29 determines whether work training is required even if the time spent on work is a predetermined time or more, or the number of times or the ratio of work that has passed a predetermined time or more is a predetermined value or more. may be determined to have occurred.

When the work training determination unit 29 determines that work training is necessary for the worker who performed the inappropriate work, it sets execution of work training for the worker who performed the inappropriate work (S15). ).

By acquiring the work training request, the work training determination unit 29 determines that work training is necessary for the worker who performed the inappropriate work, and notifies the worker who performed the inappropriate work via the notification unit 32. A work training request is transmitted to the worker terminal 50 of the worker (S16).

As a result, the worker who performed the inappropriate work receives work training from the work supervisor (S17). At this time, the work training management unit 30 manages the progress of work training given to the worker who performed the inappropriate work. For example, the work training management unit 30 manages the progress of work training by acquiring work event information of a worker receiving work training via the notification unit 32 .

When the work training for the worker who performed the inappropriate work is completed, the work training management section 30 of the work management system 20 receives a work training completion notice (S18).

The work training management unit 30 determines that the work training has been completed by receiving the completion request (S20).

The skill management unit 31 of the work management system 20 updates the worker's skill in the work corresponding to the work training when the work training management unit 30 determines that the work training for the worker has been completed. In this way, since the worker's skill is improved by receiving the work training, the worker can perform the work related to the work training.

This modified example also has the same effects as those described above.

(Modification 3 of Embodiment)
The configuration of the production system 1 in this modified example will be described.

Since the basic configuration of the production system 1 in this modification is the same as the basic configuration of the production systems in the first and second modifications of the embodiment, the basic configuration of the production system 1 in this modification will be described below. The description of such a configuration is omitted as appropriate. This modification differs from the embodiment in that the work management system 20a includes a work limit setting unit 28 and does not have a manager.

<Action>
The operation of the work management system 20a, the work management method, and the program in this modification will be described.

FIG. 9 is a flow chart showing the operation after the work is restricted to the worker until the work restriction is released in the work management system 20a according to Modification 3 of the embodiment. In this operation example, it is assumed that the work is performed before production, but the work may be performed during production. In this operation example, the same reference numerals are assigned to the same operations as in FIG. 6, and the description thereof will be omitted as appropriate.

As shown in FIG. 9, in the work management system 20a, through steps S21 and S22, when the work determination unit 27 determines that an event requiring work restriction has occurred (YES in S22), the work is restricted. The information on the worker for whom an event that requires is generated is output to the work limit setting unit 28 (S23a).

Further, the work restriction setting unit 28 of the work management system 20a restricts the work of the worker for whom an event requiring work restriction has occurred (S24).

The work restriction setting unit 28 notifies the worker terminal 50 of the worker whose work is restricted that the work is restricted via the notification unit 32 (S25).

Based on the work event information, the work training determination unit 29 determines whether or not work training is necessary for the worker whose work has been restricted, that is, for the worker whose work is restricted (S26). .

For example, if the number of occurrences of an event requiring work restriction is less than a predetermined number, the work training determination unit 29 determines that work training is not necessary for the worker whose work is restricted (NO in S26). . In this case, the work management system 20a terminates the processing of FIG.

For example, if an event requiring work restriction has occurred a predetermined number of times or more, the work training determination unit 29 determines that work training is necessary for the worker whose work is restricted (YES in S26). ).

In the case of YES in step S26, the work education determination unit 29 notifies the worker determined that work training is required to the worker terminal of the worker via the notification unit 32 to the effect that work training is required. 50 (S27).

As a result, workers whose work is restricted receive work training from the work supervisor. At this time, the work training management unit 30 manages the progress of work training for the workers whose work is restricted (S28).

The work training management unit 30 of the work management system 20a determines whether work training has been completed (S29). Specifically, the work training management unit 30 determines whether or not a work training completion notification has been received from at least one of the worker and the work supervisor.

The work training management unit 30 determines that work training has been completed by receiving a completion notification from at least one of the worker and the work supervisor via the notification unit 32 (YES in S29). Further, when the work training management unit 30 has not received a completion notification from at least one of the worker and the work supervisor via the notification unit 32, it determines that the work training has not been completed (NO in S29). , the process returns to step S29.

Then, in this work management system 20a, the process is finished through steps S30 and S31.

This modified example also has the same effects as those described above.
