摘要
型号研制初期,为合理确定测试性指标,需要对系统故障检测率和故障隔离率进行初步预计,但是目前工程上尚未该阶段的测试性预计方法,文中根据多年从事测试性顶层设计的工程经验,通过潜心研究,摸索出一套适合工程实际的测试性初步预计方法,通过系统各组成部分的故障率和指标初始值,经过一些列的工程计算,预计其系统的测试性指标,该方法操作简单,计算方便,工程实用性较强。
Early in the project development, to determine the test index, initially need to expect the system fault detection rate and fault isolation rate, but the project has not yet been tested in the stage of the prediction method, according to the long--term engaged in the testing of top--level design engineering experience, through painstaking research, to explore a set of practical test preliminary estimate method, the failure rate and index of each part of the system of the initial value, expected to test index of the system by engineering calculation, the meth- od is simple, easy to calculate, strong practicability.
