Early Prediction Method of Software Reliability based on Reuse Analysis

Based on the reuse reliability analysis of software function modules, a new early prediction method of software reliability is proposed. At the same time, the problem of quantitative measurement of software reuse reliability is solved, that is, the evaluation result of the reliability of each reuse component in the module is obtained by estimating the reuse similarity, and combined with the expert opinion, the principal and objective weights based on the Pearson correlation coefficient are utilized. The integration method uses the correlation degree of the weight vector as a measure of the importance of different weighting methods, and then obtains the reliability evaluation value of the entire functional module. Finally, the method is verified and illustrated by the example. The software of the "Broadcast TV Monitoring System Android Client" is used as the test object, and the evaluation results of the reliability of each multiplexing component in the module are obtained.
