Research of the Material Collaborative Distribution and Management for Mixed Model Automotive Assembly Process Based on Just-in-Time

The material distribution system provided an efficient just-in-time material supply from the warehouse to workstations for the mixed model automotive assembly. The material were classified into three kinds: direct distribution parts, sequencing parts and bundle parts in according to different shape and demand on the basis of analyzing the logistics of an automotive shop. The material coordinating control process were developed based on the material pull system and the Kanban control method. The work-in process mathematical formulate of assembly material based on AGV and AS/RS were analyzed. The material information collecting and calling system of three network structure based on field-bus was established. The function module and the software architecture of material management information system for the mixed model assembly line were developed according to the material demand of the automotive assembly process. The material management information system could distribute material timely and properly for the mixed model automotive assembly process.
