Restaurant location selection by utilizing the fuzzy preference relations

Location is a significant factor leads to the success of a restaurant operation and management. This paper utilizes the fuzzy preference relations to select a restaurant location. Pairwise comparisons are conducted to obtain the importance weights of evaluation criteria and the performance rating of alternative locations. By multiplying the importance weights of evaluation criteria and the performance rating, a performance value is determined to rank the alternative locations. Compared with the AHP, the major contributions of this proposed framework are: 1) it just takes n - 1 comparisons rather than n(n-1)/2 comparisons to obtain a complete decision matrix which has n elements; 2) the inconsistency is not occurred in this process because of additive reciprocity transitivity.
