摘要
研究了芯片制造封装生产线上由于存在多种运输车辆而形成的两环闭型排队网络模型,在考虑制造系统随机特性的基础上,构建了问题的数学模型,并提出一种重叠式分解迭代解析算法,获得了系统的产率解析结果.仿真实验和生产应用表明,该算法是有效的.
This paper described a system in semiconductor assembly line in which two type of carts cycling around.It is a typical two-loop closed production line.The mathematical model was constructed considering the stochastic character of the line.An approximation algorithm based on the overlapping decomposition philosophy and the iterative procedures to estimate the throughput were proposed.The accuracy of the estimates was studied by the experiments and the real case and it proves that the approximation method is effective.
