Abstract
Software reliability evaluation is important to attribute of software quality. A new group decision-making is provided to evaluate software reliability, where the model is based on an extended VIsekriterijumska optimizacija i KOmpromisno Resenje technique. The individual utility and individual regret in general VIKOR technique are extended to group utility and group regret. A specific regret matrix is provided in new VIKOR-based GDM method. A new ranking method is provided in a static environment. Another new ranking method is provided in a dynamic environment. To implement a user-based evaluation for software reliability, the picture fuzzy set is used for handling the questionnaire information. It is noted that the existing projection measure is not always reasonable in picture fuzzy setting. To solve this problem, a new normalization projection measure is provided in picture fuzzy setting. And a new GDM method is established for software reliability evaluation. The feasibility and practicability developed method in this work are illustrated by an experimental analysis.
