Software quality evaluation method and system based on secondary evaluation

Abstract

The invention provides a software quality evaluation method and system based on secondary evaluation. The method includes the steps that a software quality evaluation index space is selected, and a software quality evaluation result identification framework is built; sample data and data of software to be evaluated are collected; the number and the topological structures of BP neural networks aredetermined; the BP neural networks are trained in parallel, and the credibility levels are calculated; the quality evaluation index data of the software to be evaluated is input into each trained BP neural network, and preliminary evaluation results are obtained according to output results of the BP neural networks; the preliminary evaluation results are corrected in combination with the credibility levels of the BP neural networks to generate basic probability assignment of each proposition in the identification framework, and all pieces of evidence are fused according to the DS evidence theory to obtain a fusion result; decision-making is conducted on the fusion result based on decision criteria to generate a final evaluation result. By means of the method, software quality evaluation can be effectively achieved.

Description

technical field [0001] The invention relates to the technical field of software quality evaluation, in particular to a software quality evaluation method and system based on secondary evaluation. Background technique [0002] Software quality is the sum of all characteristics and all characteristics related to the ability of a software product to satisfy stated and implied requirements. Software quality evaluation is to use appropriate technology to measure the quality characteristics and sub-characteristics of the evaluated software and evaluate the measurement results, so as to give the evaluation results of whether the software product can meet specific requirements. Software quality evaluation can quantitatively give the quality level of software, and can carry out corresponding management and quality improvement of software according to the evaluation result data of software quality. [0003] At present, the evaluation methods of software quality mainly include: [00...
