A Novel Testability Optimization Algorithm Counting the Reliability of Test Points

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

The traditional testability mathematical model is attributed with inaccurate when applied in real industry occasions for it ignores the reliability of the test points (usually considered fully convinced). In this paper, we devise a novel testability optimization algorithm regarding withthe reliability of test points. First, the D-matrix of uncertainty is acquired based on the Bayes-learning. Then, quantizing the loss function with the information entropy and utilizing the global searching ability of Genetic-PSO algorithm and the efficiency of the Greedy algorithm to form the test group. The proposed algorithm is validated with test data of avionics. The experiment result shows the method is able to select the optimal test group considering the uncertainty.
