A software quality evaluation model based on hesitant fuzzy set is proposed. Firstly, according to the expert score, hesitant fuzzy set and intuitionistic fuzzy set are combined to obtain a comprehensive hesitant fuzzy evaluation matrix of software quality characteristics. Then, by calculating the hesitant fuzzy generalized comparison table, the scores of each quality attribute of the software are obtained. Finally, the quality order of the software is given according to the score. It better solves the he- sitant problem when experts evaluate software quality indicators. Specific case analysis proves that the proposed software quality evaluation model is feasible and effective.
