Project Scheduling Method Using Triangular Intuitionistic Fuzzy Numbers and Triangular Fuzzy Numbers

The critical path problem is a classical and important network optimization problem appearing in many applications, especially in planning and controlling the complex projects. However the result of classical critical path method computation cannot properly match the real-world problem. This gives rise to fuzzy environment and hence we have fuzzy critical path method. In this paper, two different algorithms are presented to obtain the critical path in a fuzzy network, where the edge weights are taken as triangular intuitionistic fuzzy numbers and triangular fuzzy numbers respectively. Definitions are coined for ranking techniques which are utilized to identify the fuzzy critical path. Illustrative examples are included to demonstrate the proposed approach. Furthermore simulation result is exhibited for the ranking techniques. Mathematics Subject Classification: 90B10, 90B15, 90B50, 90C06
