Application of Multiple Attribute Group Decision Making to Solve Fuzzy Time Cost Trade off Problems

Abstract

This research article gives out the Mathematical design and system for solving a time cost trade-off problems by using fuzzy linear programming problem and Multiple Attribute Group Decision Making (MAGDM) problems. A linear numerical template for project time cost trade-off problem is evolved through this work which gives the optimum solution. The activities presented in the network take the form of decision matrices which are solved by using aggregation operators available in the literature. Several aggregation operators are employed in the decision process and the best alternative which comprises the normal cost, normal duration, crash cost and crash duration is selected for each activity and then the optimal solution of the network is obtained. The proposed method is explored through numerical illustration.
