Research and Implementation of Customization MES with Improved Scheduling Based on RFID

Abstract

Industrial customization MES (manufacturing execution system) has become an important part of industrial 4.0 and China-made 2025 background. However, in the process of customization production, because of the large and complex demand information, a single scheduling algorithm obviously cannot meet the requirements and the production efficiency cannot reach the satisfaction level. In order to realize customized production and effective scheduling, this paper analyzes and designs the MES system on the basis of RFID radio frequency identification technology. Firstly, it presents the RFID Tag data structure as a guide to the production and feedback of the information carrier, to achieve customized production with collaboration of PLC. At the same time, an improved scheduling scheme and its evaluation method are proposed, which collects the mainstream intelligent scheduling algorithm and makes use of the logic evaluation method to make the decision, which effectively solves the problem that the single algorithm is difficult to solve the large quantity and complicated customization scheduling problem. Finally, the scheme is applied to a processing lines, and the design and development of the system is completed. At the same time, it is pointed out that the improved scheduling scheme can promote the practice of scheduling algorithm and have some practical and research significance.
