A New Sample Selection Method for Testability Verification Experiment
To solve the difficulty of equipment testability verification experiment sample selection, a sample selection method of testability verification experiment was presented. The failure-test dependency matrix and its extended matrix, failure modes function equivalence set and failure modes test equivalence set were analyzed, on the basis, failure modes sample equivalence set was proposed. Meanwhile, importance characteristic was analyzed and maximum entropy was solved, and the sample selection method was presented, its process was obtained. Moreover, the method was comparatively analyzed with actual methods in the experiment. The results show that application the method in paper, can reduce sample number, save test expenses, and meet the test requirement of adequacy, so the method in paper is proved effective and feasible.
