Abstract. The task of finding the crisp critical path has received researcher's attention over the past two decades which has wide range of applications in planning and scheduling the large projects. In most cases of our life, the data obtained for decision makers are only approximate, which gives rise to fuzzy critical path problem. In this paper, new ranking methods are introduced to identify the fuzzy critical path and the fuzzy critical length is presented in the nature of fuzzy membership function. The fuzzified version of the problem has been discussed with the aid of numerical example.
