基于可靠性的连续生产在制品库存的建模分析

Modeling of In-process Inventory in Continuous Production Based on Reliability

以可靠性理论中的可修复系统模型为基础,运用可靠性框图及马尔科夫状态转移过程、从可靠性角度分析为保证连续生产所需的在制品库存数量问题,并构建串行生产线缓冲量可靠性模型。利用可靠性模型推导出为保证连续生产、瓶颈工序前应持有的在制品库存数量的计算公式。并通过实例计算验证了该模型的有效性。

Based on the repairable system model in the theory of reliability,using reliability block diagram and Markov state transition process,the in-process inventory which should ensure continuous production was analyzed from the point of view of reliability,and a serial production line buffer capacity reliability model was established.The formula of the number of in-process inventory that was used to ensure continuous production was deduced with the help of the reliability model.It is concluded that the reliability model is valid through the calculation of an example.
