Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a production management system, and more specifically, it automatically creates a job submission sequence for improving production efficiency in accordance with a production plan of a multi-product job given by a host system. It can be applied to a production management system, and in particular, it allows each operator to accurately grasp the progress status of the working time included in the manufacturing plan, and it can be artificially reduced due to lack of personnel or operator's lack of awareness of the manufacturing plan. The present invention relates to a production management system capable of accurately grasping the progress status of working hours even if a manufacturing plan is delayed.

[0002] In recent years, production management systems are required to operate each facility without waste and manage the production schedule in order to realize more efficient product production. for that reason,
There is a demand for a production management system capable of performing production schedule management for each product based on the production plan that is considered to be the best in all processes.

[0003]

2. Description of the Related Art FIG. 5 is a block diagram showing a system configuration of a conventional production management system. The conventional production management system is composed of a plan creating unit 1001, an evaluating unit 1002, an analyzing unit 1003, an improvement plan creating unit 1004, and a history recording unit 1005.

Here, the plan creating means 1001 has basic information 1006 including product information, process information, production in process information, and dispatching rules, and a job production plan 1007 of what kind of thing should be produced and how much.
In the specific process in the target production system, by the start order determination rule 1008 including the start order determination rule and the dispatching determination rule for determining the priority order based on the plan of how to actually flow the products. By determining the start order of the jobs and performing simulation of all processes developed along the time axis with a simulator such as PC or WS, the manufacturing plan for all processes is output, and the evaluation means 1002 outputs the basic information 1006. The manufacturing plan 1 is applied by applying the evaluation rule 1009, which is an element for evaluating how much can be produced for the variety to be produced.
010 is compared with the actual manufacturing result, and the evaluation result 1011 is output.

The analysis means 1003 refers to the basic information 1006 and the manufacturing plan 1010, applies the analysis rule 1012 for judging what is wrong when the evaluation result 1011 is bad, and applies the evaluation result. Among the evaluation items in 1011, with respect to the evaluation item that does not reach the preset target value, the analysis result 1013 regarding the job and the process that causes it is output.

The improvement plan creating means 1004 uses the basic information 10
06 and the analysis result 1013, the judgment rule 1014 of which part should be improved is applied to improve the evaluation result 1011 of the evaluation item that did not reach the target value, and evaluate other evaluation items. In order to keep the deterioration of the result 1011 within a preset range, a strategy for partially changing the starting order, equipment allocation and dispatching adopted by the plan creating means 1001 is sought and displayed, and the history recording means 1005.
Records the history of the rules applied by the plan creating unit 1001, the analyzing unit 1003, and the improvement plan creating unit 1004.

In this conventional production management system, it is difficult to make a manufacturing plan satisfying all the evaluation items in one operation in a wide variety of situations in which high-mix low-volume production is targeted. Based on experience, we make trial and error one by one, and support the repetition of re-planning to create the best production plan, and then it is configured to produce at the factory based on this production plan.

[0008]

The above-described conventional production management system tries to obtain the best production plan by assisting the operator in rescheduling the production plan 1010, but regarding the items that have not reached the target value. Depending on the analysis result of the above, although the target value cannot be achieved due to the delay factor with respect to the manufacturing plan 1010, the production plan 1007 should be reviewed how the production plan 1007 is correctly executed. It's difficult to confirm. For this reason, it is difficult to accurately grasp the progress status such as the work time of the operator included in the manufacturing plan 1010 being extended, and thus it is difficult to steadily execute the manufacturing plan 1010.

Further, in the conventional production management system, since the simulation of all processes is performed to create the manufacturing plan 1010, the basic information 1006 for that purpose must be reliable. In this case, mechanical things such as processing time and transportation time of each equipment are almost constant except when there is a failure,
Even if a failure occurs, it can be detected immediately by referring to the equipment operation information.

However, in the conventional production management system, in order to process a product in each facility, it is necessary to depend on the work of the operator, and man-made production due to lack of personnel or lack of recognition of the operator's production plan 1010. When the plan 1010 is delayed, if the item is not specified, the evaluation of other items is adversely affected, and at the same time, it becomes difficult to perform the analysis. There was a problem that it was difficult to grasp.

Therefore, according to the present invention, each operator can accurately grasp the progress status of the working time included in the manufacturing plan, and at the same time, the artificial manufacturing plan can be changed due to lack of personnel or operator's lack of recognition of the manufacturing plan. The present invention relates to a production management system capable of grasping the progress of working hours even if a delay occurs, and steadily and easily executing a manufacturing plan.
