摘要
为提高物流管理绩效,考虑到农产品的易腐败特征和配送中心的配送能力限制,建立了易腐农产品配送中心选址问题的0-1整数非线性规划模型。利用该模型可以确定配送中心的开设位置、各配送中心与用户之间的配送关系,以及配送途中的农产品损耗量。为求解该模型,提出了嵌入改进表上作业法的混合遗传算法,给出了算法的实现步骤。最后通过算例,验证了模型和算法的有效性。
In order to improve logistics management performance,by considering the spoilage trait of agricultural product and the capacity limit of distribution center,this paper developed a 0-1 integer nonlinear programming model for the location problem of perishable agricultural product distribution center.With the help of the model,the following items could be determined,such as the site of the opening distribution center,the relation of distribution center to consumer,even the decay loss on the distribution way.To solve the model,it presented a hybrid genetic algorithm embedded with modified table-working ope-rations,and introduced its realization steps.Finally,it verified effectiveness of the model and its algorithm by several instances.
