基于Markov方法的多阶段任务系统可靠性分析综述

摘要

基于Markov方法的PMS任务可靠性建模方法大致可以分为统一建模、分阶段建模、层次化建模以及模块化建模，介绍了各种建模方法的主要思路及优缺点；同时，分析总结了基于Markov的任务可靠性模型求解方法，并指出大规模PMS的Markov可靠性建模与分析方法是下一步需要研究解决的问题。%The modeling methods based on Markov process of PMS mission reliability can be divided into four categories:unified modeling method,separate modeling method,hierarchical modeling method and modular modeling method.The main ideas,advantages and disadvantages of above modeling methods were introduced.Also,the mission reliability computing methods for Markov model were analyzed.On the basis of the latest research advance,the reliability modeling and analysis methods of large-scale PMS based on Markov process was pointed as an important issue in the future.
