Quantitative evaluation method and device for software product quality

The invention relates to the technical field of software quality evaluation, and provides a quantitative evaluation method and device for software product quality. According to the method, the quality index set of the to-be-evaluated range is obtained, the evaluation index hierarchical structure is constructed, a universal software quality evaluation method is established, the advantages and disadvantages of software products are quantitatively and comprehensively measured from multiple angles, and time and resources consumed by software quality evaluation are reduced; determining a criterion weight of each quality index according to the to-be-evaluated range; the index weight of each quality index is determined by obtaining the original data containing all the quality indexes, the comprehensive score of the to-be-evaluated range is obtained according to the criterion weight, the index weight and the original data, and finally the to-be-evaluated range is ranked according to the comprehensive score to obtain
