【摘要】 本文在现有连续近似(CA)模型的基础上,从供应商管理库存(VMI)角度出发,引入了PowerofTwo(POT)周期配送策略,构建了VMI环境下分销网络设计的CA模型。该模型的目标函数不仅包括了分销中心的建设 运营费用、运输费用,而且引进了实际中关注的存储费和订货费;该模型在确定分销网络结构的同时,也确定了各分销中心的库存策略和对其客户的配送策略。文中给出了模型的解法,利用此解法对算例进行求解,并分析了求解的结果,得出各参数变化对解的影响。更多还原

【Abstract】 The strategies of vendor managed inventory and ’power of two’ policy are introduced in the continuous approximation model of distribution network designing.The objective of this novel model is to minimize the sum of distribution centers’ fix cost and variable cost,transportation cost and inventory cost.Through the novel continuous approximation model,we can get the solutions of distribution network,distribution centers’ ’power of two’ policy at the same time.A solution of this model is proposed,and 13 numerical examples are computed to validate the feasibility of this algorithm,and the influences of the parameters to computed results are analyzed in this paper.更多还原
