In this paper, a new method is proposed to find the optimum solution of fuzzy networking problem. The fuzzy networking problem has been transformed into crisp network problem and it is solved by using forward and backward calculation. In this problem, denotes the duration from activity i to activity j. The distance is taken as trapezoidal fuzzy numbers, which are ranked by using ranking method. The proposed method is easy to understand and to apply for finding the fuzzy critical path of fuzzy networking problem. Numerical example shows that the fuzzy ranking method gives an effective result of fuzzy networking problem.
