产品族演进驱动下的装配线适应性动态平衡研究

Assembly line dynamic balancing (ALDB) for product family (PF) evolution is very important to raise productivity, reduce the production cost and achieve sustainable development for mass customization (MC) enterprises. PF evolution mechanism is the starting point in the present study, and dynamic market analysis, the core technology of PF, modeling and simulation and decision evaluation are used in ALDB. Theories, methods and application system based on PF evolution mechanism are presented and the positive analysis is done simultaneously. Firstly, the evolution features of customer needs, technology and product data are analyzed and obtain PF evolution laws. And then the causal association between balancing factors is studied in PF assembly line. Additionally, the model for assembly line adaptive evolution balancing is established, in which PF assembly line is adjusted and optimized using principles of changing-design and intelligent optimization technology, etc. Meanwhile, the balancing process of PF assembly line is simulated and evolution programs are evaluated. Finally, the web-based software tool is developed for ALDB in PF evolution. This study aims to reveal PF evolution laws, establish adaptive balance model for PF assembly line and obtain the best option, which provides theoretical and technical support for enterprises to improve PF manufacturing system.
