摘要
首先简要介绍了战略储备系统及其寿命过程。然后从分析系统的寿命过程入手 ,将其寿命过程分为两个阶段 ,每个阶段分别用一连续时间马尔可夫链来描述系统的动态过程 ,在此基础上给出了战略储备系统最优战略储备量计算的解析方法 。
The problem of optimum spare parts quantities of strategic storage system (n:k(S)) is first introduced by the Second Artillery Army of PLA for their needs. A major challenge of this problem is that the aging process of n:k(S) is quite different from others and more complex than that of ordinary redundant systems. In this paper, the aging process of n:k(S) is split into two stages. Each stage is modeled by a continuous-time Markov chain. An analytical method based on such Markov chain models is provided for calculating the optimum spare parts quantities of n:k(S) under the reliability restriction. Moreover, a simple and efficient formula is presented to deal with unrepairable n:k(S). The present work can be used as the guidance in the spare-part supply planning of n:k(S).
