卫星可靠性分配优化方法研究

A Study on the Optimum Approach of Satellite Reliability Apportionment

为达到满意的系统可靠性，除了采用不同的设计思想和工艺准则外，本文现介绍不改变系统的总体结构而提高某一部件可靠性的几种方法及带约束冗余变（串并联）系统可靠性的设计方法，并给出了优化设计结果，说明了方法的有效性．

n order to obtain satisfactory system reliability,in addition to adopting different design ideas and technological standards,this paper introduces several methods to illustrate how to improve the reliability of a certain part of system instead of changing the whole system's structure,and the design method to raise the reliability of system with restricted redundancy(Serial-parallel system).Furthermore, this paper presents the result of optimum design to show the effectiveness of the Approach.
