具有多层次变动环境的CIMS可靠性的位相分析

The Phase Type Analysis of Reliability on CIMS with Multiple Levels Changing Environment

本文研究了多层次变动环境，带有有限缓冲库的ＣＩＭＳ可靠性问题．其中假定两级工作站的寿命都服从指数分布，其它所有随机因素都是马氏调节泊松过程．利用准生灭过程理论，给出了系统的各种可靠性指标和生产指标，给出了由环境小变化而引起的系统指标扰动的界值。讨论了系统运行中的局部渐近性态．

This paper considers the reliability problem of CIMS with a finite buffer and multiPle levels changing environment.The life times of two working stations are assumed to take exmpential distributions,all other random factors are the Markov-modulated poisson processes.By means of quail birth and death processes theory,we obtain all reliability indexes and procuction indexes of system, give some random perturbations boundaries of system when there is a small changing of the environment, and consider some asymptotic proprties of system.
