JP 2002-215215 A

  In the conventional production management system, when calculating the production schedule, worker assignment, and equipment assignment to achieve production requirements, priority is given to the start / end schedule of each work, and the work efficiency of the worker is taken into consideration. There wasn't. For this reason, until the worker completes a certain task, the worker is not instructed to perform another task. Therefore, when a worker handles multiple tasks and performs them in parallel, there are frequent operations where there is no work to be performed and there is no worker to be worked on, and there is no worker to be worked on and there is a work waiting for the worker. It was.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to obtain a production management system capable of reducing the waiting time for the worker and the waiting time for the worker.

  The present invention is a production management system for sequentially instructing work to be performed to an operator who is engaged in a plurality of operations in a production line for producing a product, and records the worker information including the processing capability of the worker An operator information recording unit, an apparatus information recording unit for recording apparatus information including processing capability of an apparatus used by the operator for work, an operation result recording unit for recording an operation result of work performed by the operator, Based on information recorded in a production request input unit for inputting a production request including the product type, quantity and delivery date of the product, and the worker information recording unit, the device information recording unit and the work result recording unit, the production A host computer that sequentially outputs a work instruction indicating work to be performed by the worker in order to achieve the production request input to the request input unit, and the work instruction output by the host computer A production management system comprising: a display terminal for displaying, wherein the host computer outputs a work instruction so that the worker performs another work even before the worker completes a certain work. .

  According to the present invention, it is possible to reduce the waiting time for the worker and the waiting time for the worker.

It is a figure which shows the production management system which concerns on embodiment of this invention. It is a figure which shows the operation | work instruction | indication which the host computer of FIG. 1 output.

  FIG. 1 is a diagram showing a production management system according to an embodiment of the present invention. This production management system is a system for sequentially instructing work to be performed to an operator who handles a plurality of work in a production line for producing products.

  The worker information recording unit 10 records the processing capability of the worker. The device information recording unit 12 records the processing capability of the device used by the worker for work. The work record recording unit 14 records the work record of the work performed by the worker. The production request input unit 16 receives a production request including the product type, quantity, and delivery date.

  The host computer 18 uses the information recorded in the worker information recording unit 10, the device information recording unit 12, and the work performance recording unit 14 to produce a production schedule for achieving the production request input to the production request input unit 16. And calculate worker assignment and equipment assignment. Then, the host computer 18 sequentially outputs work instructions indicating work to be performed by the worker from the calculation result. The work instructions output by the host computer 18 are displayed on display terminals such as the production information display terminals 20 and 22 fixed at a predetermined place and the portable terminals 24 and 26 carried by the worker.

  FIG. 2 is a diagram illustrating work instructions output by the host computer of FIG. First, the start work of work A is instructed (S1). Next, the start work of work B is instructed during the machine time of work A (S2). Next, the start work of work C is instructed during the machine time of work A and work B (S3). Next, the end work of work A is instructed (S4). Next, the start work of the second work A is instructed during the machine time of the work B and the work C (S5). Next, the end work of work C is instructed (S6). Next, the end work of work B is instructed (S7). Next, the start work of the second work B is instructed during the machine time of the work A (S8).

  In this way, the host computer 18 outputs a work instruction so that another work is performed on the worker even before the worker completes a certain work. Thereby, it is possible to reduce the waiting time for the worker and the waiting time for the worker. Therefore, personnel, equipment, and production time can be reduced.

  The host computer 18 automatically acquires the work record recorded in the work record recording unit 14, statistically processes it, and automatically updates the worker information recorded in the worker information recording unit 10. This eliminates the need for the system manager in charge to regularly update the worker information. And even if a worker's processing capability changes with time by work experience, worker information recording part 10 can hold the newest worker information.

  The host computer 18 automatically acquires the work record recorded in the work record recording unit 14, statistically processes it, and automatically updates the device information recorded in the device information recording unit 12. This eliminates the need for system managers to regularly update device information. Even if the processing capability of the apparatus changes with time due to improvement of the apparatus, the apparatus information recording unit 12 can hold the latest apparatus information.

  Further, by using the portable terminals 24 and 26 carried by the worker as display terminals for displaying the work instruction, the worker needs to go to the production information display terminals 20 and 22 fixed at a predetermined place to see the work instruction. There is no. Accordingly, it is possible to shorten the time for the work instruction to be transmitted to the worker.

  Further, when the priority order of the work is changed due to a sudden change in the situation such as an abnormality in the apparatus or a product quality, the host computer 18 allows the first work even while the worker is performing the first work. Is interrupted and the worker is instructed via the portable terminals 24 and 26 to start the second work having a higher priority than the first work. Thereby, even when the priority order of work is changed, work with higher priority can be started by the worker without delay.

  Further, conventionally, a production schedule was created by calculating the upper limit of the current number of workers / processing capacity and the number of apparatuses / processing capacity. However, there are cases where the required number of workers or the like cannot produce the required product by the required delivery date. Therefore, in the present embodiment, the host computer 18 first calculates the number of workers / processing capacity and the number of machines / processing capacity required for producing a product of the requested product type / quantity by the delivery date. . Next, the host computer 18 compares the number of workers and the processing capacity with the current number of workers and the number and processing capacity of the devices, and compares the number of workers and the processing capacity and the number and processing capacity of the surplus or insufficient workers. calculate. Then, the host computer 18 displays the calculation result on the production information display terminals 20 and 22. As a result, it is possible to increase the capacity required to produce the required product type and quantity by the delivery date without delay.
