测试的离散信道模型与信息量

针对系统级故障诊断过程中测试信息量的计算问题,建立了测试过程的离散信道模型,提出了基于信道平均交互信息量的测试信息计算方法,并证明算法的复杂性为O(mnlogn2),为系统级故障诊断提供了精确的定量分析基础。

Discrete Channel Model and Information Gain of Test

In system-level fault diagnosis,the computation of test's information gain directly affects the efficiency of diagnosis strategy.After the building of the channel model of test,the computation method of test's information gain based on mean mutual information is presented.The complexity of the method is 0(mnlogn2).The channel model and its information gain computation method build a precise foundation for quantitative analysis of system-level fault diagnosis.
