“…MCDM methods have been applied for evaluating and ranking of alternatives under conflicting criteria with respect to subjective judgements of decision makers (DMs). Since classical MCDM methods cannot deal with imprecise and vagueness information in the decision making process, many fuzzy MCDM methods based on fuzzy sets (also known as type-1 fuzzy sets) proposed by Zadeh [30], have been presented: Fuzzy AHP (Van Laarhoven and Pedrycz [26], Buckley [4], Chang [5]), Fuzzy TOPSIS (Triantaphyllou and Lin [25], Hwang and Yoon [15], Chen [6], Wang and Elhag [28], Ashtiani et al [2]), Fuzzy VIKOR (Park et al [22], Wan et al [27]), Fuzzy COPRAS (Zavadskas and Antucheviciene [32], Yazdani et al [29]), Fuzzy PROMETHEE (Chen et al [12], Goumas and Lygerou [14]), and etc.…”
