Next, each means 31-36 is demonstrated.

(Progress status management means 31)
The progress status management unit 31 detects the update of the progress status and instructs the work allocation unit 32 to update the work allocation. The progress status management means 31 detects completion of all work processes and instructs the work performance reflecting means 36 to reflect the work performance in the DB. Hereinafter, a processing example of the progress management means 31 will be described with reference to the drawings.

FIG. 7 is a flowchart illustrating an example of processing of the progress status management unit 31.
The progress management means 31 monitors the work progress information DB 42 and determines whether or not the progress status 111 has been updated (S101). For example, the progress status management unit 31 updates the progress status 111 when the progress status 111 of a certain work process is updated from “not started” to “start”, or from “start” to “complete” or “suspend”. Is determined to have been updated. When the progress status 111 has not been updated (S101: NO), the progress status management unit 31 waits until the progress status 111 is updated.

  When the progress status 111 has been updated (S101: YES), the progress status management means 31 executes a work allocation process (S102). This is because when a work process is “completed” or “suspended”, a new work process can be assigned to the worker who was engaged in the work process. Details of the work assignment process will be described later.

  Then, the progress status management unit 31 refers to the work progress information DB 42 and determines whether or not all the work processes are “completed” (S103). When there is a work process that is not “complete” (S103: NO), the progress management means 31 returns to step S101.

  When all work processes are “completed” (S103: YES). The progress status management means 31 executes work performance reflecting processing (S104), and ends the processing (end). Details of the work performance reflecting process will be described later.

  According to the above processing, the work location and the worker assignment for the subsequent work process are appropriately updated according to the update of the progress status, so that the work efficiency can be improved.

(Work allocation means 32)
The work assigning means 32 assigns a work place and a worker to perform the work process. The work assigning means 32 may assign a work place and a worker to a work process whose progress status 111 is “Unstarted” or “Suspended” in the work progress information DB 42. Hereinafter, a processing example of the work assignment unit 32 will be described with reference to the drawings.

FIG. 8 is a flowchart illustrating an example of processing of the work assignment unit 32.
The work allocating unit 32 executes the following steps S202 to S207 for each of all work processes whose progress status 111 is “Unstarted” or “Suspended” in the work progress information DB 42 (S201).

The work allocating unit 32 refers to the work process information DB 41 and specifies the required equipment 104, the required skill 105, and the required work number 106 in the work process to be processed (S202).
The work assignment unit 32 causes the work place determination unit 32 to execute a work place determination process (S203). Although details of the work place determination process will be described later, the work place where the work process is performed is determined by this process.

  The work allocating unit 32 determines whether or not a work place for performing the work process has been determined in step S203 (S204). When the work place is not determined (S204: NO), the work assignment unit 32 proceeds to step S208 as it is. This is because the work place cannot be secured and the work process cannot be started yet.

  When the work place is determined (S204: YES), the work assignment unit 32 causes the worker determination unit 34 to execute the worker determination process (S205). Although details of the worker determination process will be described later, an operator who performs the work process is determined by this process.

  Next, the work assignment unit 32 registers the work place and the worker determined in steps S203 and S205 in the work assignment information DB 45 (S206). Then, the work assignment unit 32 transmits the work place, the work content, and the like to the worker terminal 12 of the worker assigned to the work process. In addition, the work assignment unit 32 transmits the work contents and the like to the work place terminal 11 provided in the work place used for the work process (S207).

  Then, the work allocating unit 32 returns to step S201 if a work process whose progress status 111 is “Unstarted” or “Suspended” remains (S208), and ends the process if it does not remain (end). .

(Working place determining means 32)
The work place determination means 32 determines the work place where the work process is to be performed. The work place determination unit 32 extracts one or more work place candidates capable of performing the work process from the work place information DB 44, and selects one work place from the extracted one or more work place candidates based on a predetermined condition. May be determined. Hereinafter, a processing example of the work place determination unit 32 will be described with reference to the drawings.

FIG. 9 is a flowchart showing an example of processing of the work place determination means 32.
The work location determination means 32 refers to the work process information DB 41 and specifies the required equipment 104 for the work process (S301).
The work place determination means 32 refers to the owned equipment 132 and the usage status 134 of the work place information DB 44 and extracts candidate work places that have the specified requested equipment 104 and are unused (or will be unused in the near future). (S302).

  When no work place candidate has been extracted (S303: NO), the work place determination means 32 returns to the work assignment means 32 that the work place has not been determined (S310), and the process ends (step S310). End).

  When one or more work place candidates can be extracted (S303: YES), the work place determination unit 32 determines one work place from the work place candidates based on a predetermined condition (S304). For example, the work place determination means 32 may determine the work place having the smallest number of failures 137 or failure rate 138 as one work place. This is to reduce the probability that an unexpected failure will occur during work. For example, the work place determination unit 32 may compare the requested equipment 104 with the owned equipment 132 and decide the work place where the excess retained equipment 132 is the smallest as one work place. The possibility of using the surplus holding equipment 132 in the subsequent work process is taken into consideration.

Then, the work place determination means 32 returns the determined work place to the work assignment means 32 (S305), and ends the processing (end).
With the above processing, an appropriate work place can be assigned to the work process.

(Worker determination means 34)
The worker determination means 34 determines a worker who should perform the work process. The number of workers can vary depending on the work process. The worker determination means 34 refers to the worker information DB 43, extracts one or more worker candidates capable of performing the work process, and based on a predetermined condition from the extracted one or more worker candidates, A predetermined number of workers may be determined. The predetermined number of persons may be determined by the requested number of persons 106 in the work process information 100. Hereinafter, a processing example of the worker determination unit 34 will be described with reference to the drawings.

FIG. 10 is a flowchart illustrating an example of processing of the worker determination unit 34.
The worker determination means 34 refers to the work process information DB 41 and identifies the required skill 105 and the required number of workers 106 for the work process (S401).
Then, the worker determination means 34 refers to the possessed skill 123 and the work situation 124 in the worker information DB 43, and has the required skill 105 identified in step S401 and is not working (or is not working in the near future). Candidate candidates are extracted (S402).

  When the number of candidate workers is less than the required number of workers 106 (S403: NO), the worker determination means 34 determines all the extracted candidate workers as workers in the work process (S410), and step The process proceeds to S406. In this case, the worker determination means 34 may return to the work assignment means 32 that the required work number 106 is not reached in step S406.

When the worker candidate is equal to or more than the required number of workers 106 (S403: YES), the worker determination unit 34 requests the requested work based on a predetermined condition (for example, the degree of relationship) from the extracted worker candidates. Determine the number of workers. For example, the worker determination means 34 selects a leader in the work process from the worker candidates, and calculates the degree of relationship between the leader and other workers (S404). Here, the leader may be selected based on the years of experience 122, the level of the possessed skill 123 and / or the number of process experiences 126, and the like.
Then, the worker determination unit 34 determines the remaining workers to be assigned to the work process based on the calculated degree of relation (for example, in descending order of degree of relation) (S405).

  Here, the degree of relationship is a value indicating a high degree of relationship between workers. For example, the degree of relationship between workers who frequently collaborated may be calculated high. This is because there is a high possibility that workers who have collaborated frequently will be able to work more efficiently.

  For example, the degree of relationship between workers with high likability may be calculated high. The good sensitivity may be obtained, for example, by a questionnaire survey from the worker terminal 12, or may be obtained by analyzing data acquired from an electroencephalogram sensor provided in the worker terminal 12. The degree of relationship may be set manually by an administrator or the like.

  For example, the degree of relationship between other workers having a relatively high level of possessed skills 123 with respect to the possessed skills 123 of a relatively low level among the retained skills 123 of the leader corresponding to the required skill 105 of the work process is as follows. It may be calculated higher. This is because the weak points can be complemented with each other when working together.

Then, the worker determination means 34 returns the determined worker to the work assignment means 32 (S406), and ends the processing (end).
With the above processing, an appropriate worker considering the relationship between workers can be assigned to the work process.

(Work instruction means 35)
When the work assignment is updated in the work assignment means 32, the work instruction means 35 is provided with the work place terminal 11 provided in the work place used for the work process, and the worker assigned to the work process. The information regarding the work process is transmitted to the worker terminal 12 of the. The work instruction unit 35 may transmit information on a work place where the work process is performed to the worker terminal 12. The work instruction means 35 may transmit the fact to the worker terminal 12 of the worker selected as the leader. The work instruction unit 35 may transmit to the work place terminal 11 equipment used in the work process, points to be noted in the work process, a list of workers assigned to the work process, and the like.

(Work result reflecting means 36)
The work result reflecting means 36 reflects the results of each work process in the worker information DB 43 and the work place information DB 44 after completing all work processes. For example, the work performance reflecting means 36 reflects the performance of the current work process in the work place information 130 relating to each work place used in the current work process. For example, the work performance reflecting means 36 reflects the performance of the current work process in the worker information 120 of each worker who has performed the current work process.

  Through these processes, the work management apparatus 10 can appropriately assign a work place and a worker who perform the work process in the cell production method or the like. That is, the work efficiency in the cell production method or the like can be improved.

  The above-described embodiments are merely examples, and are not intended to limit the scope of the present invention only to these embodiments. Those skilled in the art can implement the present invention in various other modes without departing from the gist of the present invention.
