一种用于可靠性参数指标分配的新方法

提出了一种按组成系统的各单元任务失效率比例，并考虑各单元的重要度来分配系统可靠性参数指标的新方法；给出了分别以失效率、平均故障间隔时间表达的分配比例因子及分配公式。该方法是ＡＧＲＥＥ分配法的改进。文末举例说明该方法的应用及其分配结果的合理性

A New Method of Index Allocation for Reliability Parameters

A new method of index allocation for reliability parameters of a system is presented according to the proportion of mission failure rates of the units of which the system is composed,and their degrees of importance. The proportional allocation factor and the allocation formulae expressed in terms of failure rates and mean time between failures respectively are given.The method is an improvement on the AGREE allocation.At the end of the paper,an example is given to illustrate the application of the method and the rationality of its allocation results.
