“…9 −1 ∀i = j criterion i is relative importance to criterion j criterion i is equal importance to criterion j criterion i is relative less importance to criterion j (4) Transforming fuzzy scales into triangular fuzzy numbers As shown in Figure 2, this work used a fuzzy five-scale linguistic scaling to weigh the importance of each dimension/criterion. It includes "equally important," "moderately important," "important," "very important," and "extremely important;" and each has its related triangular fuzzy numbers (1,1,3), (1,3,5), (3,5,7), (5,7,9), and (7,9,9), respectively. Referring to Mon et al [39], each scale of fuzzy number is defined by three parameters (i.e., the left, middle, and right points) of the symmetric triangular fuzzy number.…”
