摘 要: 三维系统广泛应用于空间环境监测领域。Consecutive-(r1, r2, r3)-out-of-(m, n, w):F系统是典型的三维可靠性系统,由m×n×w个单元组成,系统的失效准则为当且仅当存在一个三维矩阵(r1, r2, r3)区域,该区域内所有单元均失效。这里针对特殊三维系统Consecutive-(2, 2, 2)-out-of-(m, n, w):F系统,应用有限马尔可夫链嵌入法,构造了状态空间和转移概率矩阵,进而给出系统可靠度的解析表达式。数值结果表明:研究提供的方法对给定的特殊三维系统可靠度计算有效。
关 键 词: 马尔可夫过程;可靠度;质量控制与可靠性管理;三维系统

Abstract: Three-dimension systems can be used to monitor space environment. Consecutive-(r1,r2,r3)-out -of-(m,n,w):F systems is a typical three-dimension system. It consists of m譶譿 components. The system fails if and only a three-dimension (r1,r2,r3) area exists, and all components failed in this area. In this paper, for Consecutive-(2, 2, 2)-out-of-(m, n, w):F system, the state space and transition probability matrix was constructed and analytical expression of reliability was proposed by using finite Markov chain imbedding approach. Numerical example showed that the new method was effective.
Key words: Markov process; reliability; quality control and reliability management; three-dimension system
