An evaluation approach to software quality based on quality cloud

Quality evaluation is the key technology for software quality assurance,with characteristics of fuzziness,uncertainty and multi-attribute.In view of the outstanding characteristics of the cloud model during the process of transforming a qualitative concept into a set of quantitative numerical values,a novel software quality evaluation method based on quality cloud and quality change cloud is proposed.The expected value and hyper entropy of software quality cloud is used to evaluate software quality,and a software quality change cloud model is designed to depict changes in software quality so as to provide additional evidence.The empirical study indicates that the proposed method is effective in assessing software quality,with an apparent advantage in effectiveness and precision.
