NUMERICAL SIMULATION OF DYNAMIC PRODUCTION SCHEDULING BASED ON ICAM

Abstract

In order to resolve the problem of unreasonably allocating resources during the production process in discrete manufacturing enterprises, a method of dynamic production scheduling based on Information Coordinates Analysis Method (ICAM) was put forward. The communication modes of manufacturing equipment and the characteristic of the manufacturing process were analyzed, and the real-time data acquisition system for production field was established. The production information repository was built by analyzing the collected real-time data. With abstracting the correlative information, the information nodes were produced and the information coordinates were established. With the support of real-time information repository, the information in the production field could be available at any time by analyzing the typical information nodes. The feedback information could affect the original scheduling, thus the dynamic production scheduling was realized. Comparing with the classical analysis methods, ICAM can reflect the utilization state of the resources more directly during the process of the production scheduling, the scheduling rules can be set down more conveniently, and it is easier to apply the Object-Oriented method into the numerical simulation of production scheduling. The result of the numerical simulation proves that ICAM can effectively optimize the process of the typical production scheduling.
