物流中心选址数学模型
内容摘要

本文基于规模经济理论的思想,利用德尔菲法和层次分析法,提出了符合规模经济要求的物流配送中心选址模型,该模型既能确保物流中心满足本区域的物流需求量,又可通过对有物流服务需求的区域进行分块,减少物流服务中物流成本的重复计算,降低数据调查的难度与模型求解的难度。在定量方法上,针对第三方物流企业选址的要求,以物流中心收益最大化为目标,并同时考虑物流中心固定运营成本和可变运营成本以及退货所产生的损失费用等因素,提出了一种改进的启发式算法,并建立了实现收益最大化的数学模型。

Abstract

The author adopts the Delphi method and analytic hierarchy process to make research on the problem of the choice of logistics distribution center based on the thought of the scale economy theory. At the same time ensuring the logistics distribution center to satisfy the logistics demand in this zone,the author puts forward a model for the location of logistic distribution center based on the scale economy theory. The logistic center based on this model can meet the requirement of the quantity of demand within its own region,decrease the difficulty of data investigation. The logistics center location occupies an important strategic position for the programming and design of logistics centers. To meet the third party physical distribution enterprise's requests, take the maximization of logistic center's income as the goal, and consider the factors such as the fixed cost and the invariable cost of logistic center, as well as the loss of the returned goods, a new model of selecting logistic center is constructed. According to the model, a new improved particle heuristic algorithm is proposed.
