Abstract

In the existing methods for solving unbalanced (availability < demand) fully fuzzy transportation problems generally a dummy source is added with zero fuzzy transportation costs. Since this dummy source does not have any significance in reality, by doing so it is not possible to find the availability of which source should actually be increased so that the total demand is met and the total fuzzy transportation cost is minimized. Till now, in literature there is no such method which could give us this kind of information. In this paper, a method is proposed for solving unbalanced fully fuzzy transportation problems. The fuzzy optimal solution, obtained by the proposed method, is in terms of the original sources only and total demand is also satisfied. From the fuzzy optimal solution obtained it can be found that the availability of which source should be increased.
