Novel similarity measures, entropy of intuitionistic fuzzy sets and their application in software quality evaluation

Intuitionistic fuzzy sets (IFSs), including member and nonmember functions, have many applications in managing uncertain information. The similarity measures of IFSs proposed to represent the between different types sensitive However, some existing do not meet axioms similarity. Moreover, cases, they could be applied appropriately. In this study, we novel constructed by combining exponential function membership functions negative non-membership functions. paper, also a new entropy measure as stepping-stone calculate weights criteria multi-criteria decision-making (MCDM) model. used rank alternatives Finally, MCDM model evaluate quality software projects.
