摘　　要：以关联多工序制造系统为对象,综合考虑机器的暂态过程以及加工工序的关联性,构建了关联多工序制造系统暂态过程的马尔科夫质量分析模型,并对相关质量特性瓶颈参数进行了研究分析.通过F系列航天阀门多工序制造系统案例验证了提出的模型和分析方法的有效性.Modern manufacturing systems usually adopt multi-stage and multi-product production mode. When changing product type, due to the adjustment of fixture and craft, system goes through a transient phase. The phase can be long or short depending on parameters of the system, and affect the rate of quali- fied products seriously. There are many mature analysis methods and successful cases about steady-state, but lacking transient phase models which connect product quality and parameters of a system. In this paper, we focus on transient analysis of Markovian model of manufacturing systems. The transient phase of manufacturing system and the relevance of processing steps are analyzed, and a Markovian model of multi- stage manufacturing systems in transient phase is developed and some analysis is carried out for quality bottleneck parameters identification. The effectiveness of this model is validated by multistage manufacturing system of astronautic valve used in a domestic rocket manufacturing company.
