【摘要】 在实际物流配送系统中,需求和成本会随时间的变化而变化。针对已有选址模型没有考虑时间变化对最终选址决策的影响问题,本文建立了一种需求基于时间变化的动态选址模型,提出基于矩阵运算求解方法。并以实例说明如何找出配送中心动态最优的选址方案,使得计划期内的累计总成本最低。该方法较动态规划方法更为简单直观且无需反推最优序列。更多还原

【Abstract】 In the actual logistics distribution systems,the demand and the cost can change with time.Many models solving the location problem are stationary models,in which time factors are not considered.This paper develops a dynamic location model in which the time influences the demand,applies matrix operation method to a case and analyses how to make a loca-tion decision and bring the minimum total costs,during a company’s planning horizon.This method is visual and simple,es-pecially,it isn’t necessary that the optimizing decision is obtained by working backward from the end of a problem toward the beginning comparing with dynamic programming.更多还原
