摘　　要：为评价和优化串行多环返工生产系统的生产性能表现,结合质量管理与精益生产的理念,区别于传统的返工机制,提出一种全新的"即刻返工"检查机制,将生产系统建模扩展至多机多缓冲区的复杂生产系统.基于生产系统的两大要素,机器与缓冲区的生产状态变化,依据概率论与马氏定理,构建缓冲水平的动态概率转移矩阵,以在制品库存水平及系统平均生产率作为研究指标,针对生产设备及缓冲区展开瞬态分析,通过迭代计算,表明设置合理的系统规模与缓冲区阈值能达到优化系统生产性能的目的,并通过数值实验验证其有效性.To evaluate and optimize the performance of the serial production lines with multiple rework loops,according to the principles of quality management and lean production,a novel inspection mechanism,"Instant Checking",different from the traditional ones,was introduced in this paper.The PSM problems to the systems with multiple machines and buffers were investigated.Based on the probability theory and the Markov chain,a dynamic probability transition matrix was built to disclose the relationships between the production performance(WIP:work-in-process inventory and PR:production rate)and the status of machines and buffers.Further,the transient analysis on the machines and buffers was conducted with iterative computation.The results of the analysis show the feasibility to improve the production performance by optimizing the system′s scale and buffer capacity.The numerical experiments were conducted to verify the effectiveness of this model.
