Abstract

AHP is an effective tool for dealing with complex hierarchical decision making problems (Saaty, 1980). It divides a large complex problem into small and easily solvable sub-problems and then combines the solutions of these small problems in order to obtain the solution of the large problem. AHP uses a 1 to 9 scale whose linguistic expressions are defined accordingly. However, the representation of a linguistic term by an exact number may not fully reflect a decision maker’s judgments in his/her mind. Fuzzy numbers and scales have been developed to consider this issue in the literature (Zadeh, 1965). In this essay, a brief literature review on fuzzy AHP studies is given.
