“…Equally important 2= (1,2,3) Somewhere between equally important and slightly important 3= (2,3,4) Slightly important 4= (3,4,5) Somewhere between slightly important and more important 5= (4,5,6) More important 6= (5,6,7) Somewhere between more important and much more important 7= (6,7,8) Far more important 8= (7,8,9) Somewhere between far more important and important 9= (8,9,9) Vital The fuzzy consistent matrix is established Fuzzy consistent judgment matrix R represents the comparison of the relative importance between this level and its related elements for an element in the upper level. It is assumed that the element C in the upper level is the same as the element a1, a2,..., and is connected, then the fuzzy consistent judgment matrix can be expressed as Figure 7 (1) Establish a fuzzy consistent matrix A fuzzy consistent matrix is consistent with human decision thinking.…”
