A time_variant model of a transshipmint_related products assignment problem is stablished in this paper. The problem is formulated as a bilevel programming problem. The lower_level subprogram is the basic transshipment problem,which can be solved by common linear programming routines. The upper_level subprogram is to make the system cost lowest, which can be solved by a genetic algorithm. A lot of computational experiments are carried out and during the experiments, the comparison between genetic algorithm and common routine is presented. It is shown that the proposed model has the advantages of simplicity and short convergence time by using genetic algorithm.
