Study on ranking method for reciprocal judgment matrix with fuzzy numbers based on Hausdorff metric distance

Propose method for ranking reciprocal judgment matrix with trapezoidal fuzzy numbers based on Bonissone calculational method, Hausdorff metric distance and fuzzy compromise decision method. By introducing the methods for transforming exact numbers and triangular fuzzy numbers into trapezoidal fuzzy numbers, the ranking method is also practicable for ranking reciprocal judgment matrix with exact numbers and triangular fuzzy numbers. The computational process is illustrated by a numerical example.
