Abstrak

The purpose of this paper is to study fully fuzzy multi-choice multiobjective linear programming problem (FFMMOLPP), in which, right hand side of each constraint has two choices. With the help of ranking function, deviation distance and deviation degree between two fuzzy numbers are defined. A new method is proposed to find the d - fuzzy pareto optimal solution of FFMMOLPP which is defuzzified by using deviation degree and ranking function. Furthermore, a comparative study of the existing methods in the literature and proposed method is conducted for the particular case of FFMMOLPP. Hereafter, a real world problem is presented to illustrate the efficiency of proposed method.
