Study on the location of distribution center: a genetic algorithm combining mechanism of simulated annealing

The location of distribution center (DC) is one of the most important decision issues for logistics managers. In this paper, 0-1 mixed integer linear programming model of location of distribution center of two-stage logistics chain network is given. The design tasks of this problem involve the choice of distribution center to be opened and the optimal assignment of product flow between suppliers and customers via distribution centers to meet the demand with minimum cost As the solution method, a genetic algorithm combining mechanism of simulated annealing that is proved effective in dealing with the NP-hard problem is proposed.
