Modelling Approach

This paper presents an optimization based mathematical modelling approach for a transshipment problem with fuzzy cost coefficients is formulated and solved as a quadratic mixed integer linear programming problem. In this paper, it is illustrated how convert the fuzzy form to crisp form an illustrative numerical example is gives to clarify the formulation and the solution.
