On solving fully intuitionistic fuzzy transportation problem via branch and bound technique

Abstract

In dealing with real world transportation problems, several issues are frequently encountered as a result of uncontrollable factors. To deal this uncertainties, many authors have suggested transportation problems with intuitionistic fuzzy parameters. In this article, fully intuitionistic fuzzy transportation problem (InFTP) is considered in which the parameters are triangular intuitionistic fuzzy numbers. To solve this, initially intuitionistic fuzzy branch and bound technique is applied to get the initial basic feasible solution and then intuitionistic fuzzy modified distribution method is applied to acquire the optimal solution of the fully InFTP. Also a new ordering is developed here in which the compensation, linearity and additive property is satisfied. The optimal solution obtained from the proposed method satisfies the condition of optimality and feasibility. Finally two numerical examples are provided to show the effectiveness of the proposed method. From the comparative analysis, the proposed approach shows better optimal solution than existing methods.
