• FUZZY CRITICAL PATH BASED ON INTERVAL VALUED LINGUISTIC FUZZY SETS

Abstract

Fuzzy set theory plays an important role to aid research in fuzzy critical path analysis when the dynamics of the activity times are provided by fuzzy numbers. Previous studies on critical path analysis have demonstrated the use of fuzzy numbers as activity times in a fuzzy project network.  In this paper, interval valued linguistic fuzzy sets are used to find fuzzy critical path in a fuzzy project network. The interval valued linguistic fuzzy variables can provide a more accurate activity times in project network analysis. New arithmetic operations on linguistic fuzzy numbers are defined to get accurate fuzzy critical path in a fuzzy project network using Technique for order preference by similarity to ideal solution (TOPSIS) method.
