In a fuzzy project network, the higher risk path is called possible critical path. Secondary critical path is one of the possible critical path in fuzzy project network and it plays an important role in the project scheduling, risk analysis and time-cost trade-off problems in fuzzy environment. In this paper, triangular fuzzy numbers are used to express the operation times for all activities in fuzzy project network. We propose a method to find secondary critical path(s) in a fuzzy project network using the fuzzy free float. RM approach is used to rank fuzzy numbers to find fuzzy critical path. Two examples are given to describe the method.
