In this paper, characteristics of fuzzy project network using statistical data are discussed in detail in order to calculate the fuzzy critical path, fuzzy earliest times, fuzzy latest times and fuzzy total float. Fuzzy number as fuzzy activity time is constructed using interval estimate by calculating mean, variance and standard error. A new ranking function is used to discriminate the fuzzy numbers used as activity times in the fuzzy project network and used it in distance measure. The appropriateness and contribution of characteristics of fuzzy project network to ship building is discussed and calculated as an application to real life problem using statistical parameters.
