A Fuzzy approach using generalized Dinkelbach's algorithm for multiobjective linear fractional transportation problem

Abstract

We consider a multiobjective linear fractional transportation problem (MLFTP) with several fractional criteria, such as, the maximization of the transport profitability like profit/cost or profit/time, and its two properties are source and destination. Our aim is to introduce MLFTP which has not been studied in literature before and to provide a fuzzy approach which obtain a compromise Pareto-optimal solution for this problem. To do this, first, we present a theorem which shows that MLFTP is always solvable. And then, reducing MLFTP to the Zimmermann's "min" operator model which is the max-min problem, we construct Generalized Dinkelbach's Algorithm for solving the obtained problem. Furthermore, we provide an illustrative numerical example to explain this fuzzy approach. © 2014 Nurdan Cetin and Fatma Tiryaki.
