Fuzzy multi-criteria decision making on combining fuzzy analytic hierarchy process with representative utility functions under fuzzy environment

In 1980, Saaty proposed the analytic hierarchy process (AHP) to evaluate alternatives with multi-criteria being multi-criteria decision making. Then, numerous approaches engaged on extension of AHP under fuzzy environment named fuzzy analytic hierarchy process (FAHP) for evaluation of multi-criteria alternatives under fuzzy environment being fuzzy multi-criteria decision making (FMCDM). In the current approaches, the extent analysis method proposed by Chang in 1996 was a famous FAHP method for FMCDM. However, computing priorities in matrix by Chang’s method is difficult for comparing pairwise fuzzy numbers, and calculating possibility degrees has drawback for some special fuzzy numbers. To resolve above ties, we combine FAHP with representative utility functions under fuzzy environment. Through combination of FAHP and representative utility functions to FMCDM, our method easily and quickly solves FMCDM problems.
