摘要
针对已存在的多级物流配送网络没有充分考虑配送节点的可能状态的问题,根据一段时期产品的需求量不同等特点,通过动态调整节点关闭状态,以最小化企业物流网络的总体费用为优化目标,构建了可描述带能力约束的多级配送网络设计问题的优化模型.根据物流配送网络设计问题的特点,基于模拟退火算法思想,结合该模型对算法做出了改进,并使用改进后的模拟退火算法对模型进行求解分析.算例的计算结果表明,该优化方法运算快捷,所求结果合理,是解决相关物流问题的一种有效方法.
In order to solve the problem that the possible states of distribution nodes are not fully considered in the existing multi-level logistics distribution network,according to the feature that the demand of products in a certain period is different,and through dynamically adjusting the closed states of nodes and taking the minimization of overall cost of logistics network as the optimization goal,the optimization model,which could describe the capacity constraint, for the multi-level logistics distribution network design was established. According to the characteristics of logistics distribution network design problem and based on the simulated annealing algorithm,the algorithm was improved in combination with the proposed model,and the solution and analysis of the model was performed with the improved simulated annealing algorithm.The calculated results of examples showthat the optimization method has fast operation speed,can give the reasonable results,and is an effective method of solving the related logistics problems.
