Abstract: Aiming at the accuracy and timeliness issue of materials distribution for mixed model assembly line under uncertainty,a dynamic Just-In-Time(JIT)material distribution control system based on Radio Frequency Identification(RFID)technology was presented.With the research of material distribution characteristics and material classification,the uncertain factors in material distribution such as production plan change,production takt fluctuations,line-side inventory,material requirement and required time were analyzed.By considering various uncertain factors,the overall architecture of dynamic JIT material distribution system based on RFID was presented.The hardware and software architecture of material distribution control system were designed after studying the material distribution program models of computation and establishing visual monitor system for the assembly process.With the mixed model assembly line of a company 1.5 TGDI engine plant as an example,a RFID-based dynamic JIT material distribution system was developed based on J2EE framework.The integration and visualization of material distribution's management and control was realized,and the feasibility and the effectiveness of proposed system were verified.

Key words: mixed model assembly line, radio frequency identification, material distribution system, uncertainty
