The score function is used to compare intutionistic fuzzy numbers. In this paper, a novel score function of intuitionistic fuzzy sets (IFSs) is investigated. The novel score function was constructed by combining the polynomial and exponential functions working on the degree of membership and degree of non-membership of intuitionistic fuzzy sets. Then, the newly obtained measure overcomes the limitations of some existing score functions. Next, we applied the new measure to construct a method to deal with a multi-criteria decision-making (MCDM) problem. Finally, this MCDM model was used to assess the quality of software projects. The results showed that the new measure was well done and better than other score functions in some cases. This demonstrate the effectiveness of the newly proposed method.
