摘　　要：本文对航天系统中应用广泛的一类典型的非单调关联系统（ｎ中取ｒ至ｓ系统）进行了可靠性分析，比较了目前对系统进行可靠度计算的几种方法的优劣，详细研究了给定ｒ，ｓ及不同部件可靠度ｐ_ｉ的情况下，使系统效益达到最高的条件ｎ值的最优配置问题，并结合国外某类航天系统工程中的计算机集成系统给出了一个数值例子，并用面向 Ｗｉｎｄｏｗｓ的 ＶＢ６． ０实现了一个图形交互的求解系统最优配置和系统可靠度的软件．In this paper,reliability analysis for a typical non-coherent system (r-to-s-out-of-n) commonly used in the aerospace field is discussed. Several existing computing methods for the system reliability are also analyzed. Also studied in detail are problems of optimal design under the condition of given r,s and components of different reliability p, and when system has its highest efficiency. Through the study of a computer integrated system in a certain aerospace system engineering aboard,we have shown a numerical example. We also compiled a software based on VB6. 0 for solving the optimal design of a system and its reliability.
