提出一种将库存控制决策和设施选址模型相结合的优化方法，用来解决一类多商品物流网络优化设计问题，网络内的用户需求是随机的且服从正态分布，优化设计的目的是在满足一定服务水平的前提下，最小化物流网络内包括建设费用、储存费用和运输费用在内的总成本费用，建立了一个能同时描述设施选址决策和库存决策的多商品物流网络设计问题的非线性混合整数优化模型，并使用组合模拟退火算法对其进行求解分析，最后的算例计算结果验证了模型和算法的有效性．

A simultaneous approach that incorporates inventory control decision into facility location model is proposed, which is used to solve the multi-commodity logistics network design problem. The retailers＇ demands are stochastic and normal distribution. The objective is to minimize the total cost that includes location costs and inventory costs and transportation costs under given service level. A non-linear mixed integer programming model which simultaneously described the inventory decision and the facility location decision is presented. The combined simulated annealing algorithm（CSA） is developed to solve the problem. The model and effectiveness of the algorithm are clarified by computational experiments.
