从系统的角度考虑在配送中心选址决策过程中，处于物流企业上层和下层之间的有机联系，深入的分析了两者所追求的目标、面临的约束以及相互影响，并在此基础上构建了上层以总成本最小为目标，下层以无法及时响应所带来的服务惩罚最小为目标的双层规划模型。根据模型的特点，利用免疫遗传算法求解在不同配送中心方案数目下，上下层模型的最优解，并最终确定双层规划的解。以某电网公司的电力物资配送网络的实际数据和配送中心选址问题为算例验证了模型和算法的有效性和实用性。

From the perspective of system,the paper analyzes the relationship between the upper and lower of logis-tics enterprises in the decision-making process of distribution center location,and carries out in-depth analysis of the objectives,constraints and interaction between these two levels.On the basis of above analysis,the paper builds a bi-level programming model.The objective of the upper model is to minimize the total cost (including re-construction costs and distribution costs),and the objective of the lower model is to minimize the service punish-ment cost caused by the failed service response.According to the model’s characteristics,the above issue is equiva-lently to solve the optimal solutions for the upper and lower under the different numbers of distribution centers,and ultimately determines the solution of bi-level programming model.Due to the fact that bi-level programming problem is a NP hard problem,the paper uses the immune genetic algorithm to solve this problem.Finally,the practicality and effectiveness of the proposed model and the algorithm are verified by an example of a power grid company with actual data.
