摘    要:本文对带有中间缓冲库的可修CIMS可靠性进行了深入系统的研究.中间库是将刚性联 结生产线进行柔性化的手段,是提高系统可靠性和生产率的有效措施.另一方面,工作站的维 修也能起到同等重要的作用.但这样组成的大系统存在生产线的畅通、生产率的协调等问题, 给系统可靠性与优化设计造成了很大的困难,长期以来没有得到很好的解决. 本文从马尔可夫过程的排队论出发,运用系统可靠性理论,对缓冲库、工作站及系统进行 分步分析,综合求解,从而得出一条工件流平衡定理,解决了各站之间生产率丢失的问题,并给 出了系统可靠性的有关指标.

关 键 词:计算机综合制造系统(CIMS)    大系统可靠性    排队论    中间缓冲库

Abstract:A new analysis method is proposed for studying the reliability of a repairable CIMS with finite buffers. These buffers lead to blockage and starvation in the transfer lines and is very difficult to solve in a system.By means of queueing theory of Markov process, we analyze the intermediate buffer, equivalent workstation and system reliability in steps. From the principle of equilibrium, a theorem of necessary and sufficient condition without loss of any working parts in the transfer lines is given, which can help us to solve the problem and obtain the accurate result. Finally, two examples are given for illustrating the application of this method.
Keywords:Computer integrated man facturing system  reliability of large scale system  queueing theory  intermediate buffer
