Analysis of the Critical Path of Fuzzy Network Plan Base on S-type Membership

Based on the study on triangle or trapezoidal fuzzy network plans,this paper analyzed the feasibility of determining the critical path of fuzzy network plan with S-type membership function,and pointed out the problems when using the zero total float time to determine the critical path of fuzzy network plan,and therefore the concept of correlation area was suggested.Depending on the principle that the closest path to the total time limit is the most significantly influential on the project duration,the paper obtained the method of determining the critical path.
