Research on Fuzzy Extension Synthesis Evaluation Method for Software Quality

Based on the requirements and characteristics of software quality comprehensive evaluation, the defects caused by original fuzzy synthesis evaluation algorithm and multilayer matter-element extension evaluation algorithm are systematically analyzed and discussed. These defects are mainly resulted from the calculation of "taking large and taking small value" of the fuzzy comprehensive evaluation algorithm and the complex computing process of the multilayer matter-element extension evaluation algorithm, and also lead to the loss of a large amount of valid information and the multilayer transmission distortion of intermediate measurement data. Therefor, this paper extracts the excellent calculating structure from the two original algorithms and creates a new fuzzy extension synthesis evaluation method for software quality. The accuracy and reliability of software quality metrics are also obviously improved with the new algorithm.
