Fuzzy analytic hierarchy process (FAHP) integrates many merits of AHP and fuzzy comprehensive evaluation organically. It determines the weight of each affecting factor using analytic hierarchy process at first, and then uses the fuzzy comprehensive evaluation method to determine each scheme index. FAHP can effectively enhance the decision-making efficiency.展开更多
