[Abstract]:Radio Frequency Identification (RFID) is the basic technology to realize the standardization of information. It can realize the rapid and accurate information collection and processing in real time. It is an important technical support and means for modern enterprises to reduce production cost, improve the degree of logistics automation, realize the sharing function of production management information and improve the core competitiveness of enterprises. Radio Frequency Identification (RFID) technology is very suitable for discrete assembly lines, which can meet the requirements of discrete assembly lines for logistics systems and the complexity of assembly production. Through the rational application of RFID, the resources are allocated reasonably, and the production efficiency of discrete assembly line is improved by improving the automation degree of the system. Based on the analysis of the characteristics and present situation of the logistics system of modern automobile enterprises, this paper analyzes the logistics system and current situation of the automobile enterprises, and constructs the discrete production logistics system of products based on RFID technology. The whole complex and huge logistics system is simplified into three simple logistics modules, which are the storage logistics system module, the outbound logistics system module and the assembly line logistics system module. Combined with the advanced information processing technology of RFID technology, the production process and information management system of the whole discrete assembly line logistics system are optimized and designed, and the rationality of the optimized scheme is verified by Flexsim simulation software. In the logistics system, the main operations involved are the inventory of goods, the transportation and parts picking, and the information management of the whole module. A modern optimization algorithm is used to calculate the shortest path, and the RFID technology and the PLC technology are combined to realize the real-time information transmission and timely management. In the assembly and production module of the logistics system, the radio frequency identification technology is used to distribute the parts, and the mechanical rotation part of the simple shunt module is designed, which makes the whole device realize the automatic sorting function and reduce the labor intensity of the workers. Enhanced the flow of information throughout the process. In the process of analysis and optimization, the simulation of actual production is carried out by setting the parameters of Flexsim software, including the logistics system module, the assembly production module, and the simulation results before and after the optimization. The feasibility of applying RFID to logistics system simulation is analyzed. Through the whole logistics system more comprehensive, fast, accurate monitoring and management, not only can improve the automation of assembly line, warehouse management efficiency, but also improve the information flow of the entire logistics system.
