The aim of this paper is to build and solve a bi-objective fuzzy transportation model with three types of transshipment in equilibrium condition. In this paper, availability at the sources, demand at the destinations, transportation cost for unit quantity of the commodity and transportation time are presented by trapezoidal fuzzy numbers. Fuzzy buffer stock, α-cuts, linear membership function and minimal operator have been used to derive the optimal compromise solution, and the specific steps of the algorithm are also given. The model proposed in this paper has practical significance, and the algorithm is easy to apply to transportation problem in real life be- cause it is drawn from classical transportation algorithms. A numerical example is presented to demonstrate the validity of the proposed algorithm.
