Software Quality Comprehensive Evaluation Model Based on Rough Set Theory and Grey Theory

From the beginning of software development to the present software development, the assessing of the software quality and the assurance of the software quality has already become an important and indispensable factor in software development So it is important to evaluate the software to improve its quality. This paper first analyses the current software quality evaluation methods and their shortages. By establishing evaluation index systems, it proposes a fuzzy comprehensive evaluation model of software quality based on rough set theory and grey theory. Namely, it uses grey statistic method to establish fuzzy evaluation matrix and obtains the weight of every index by rough set theory, then evaluates software quality by fuzzy comprehensive evaluation method. The model gives a beneficial academic reference to promote software quality. Finally, an example is given to show how to use the model to evaluate software quality.
