冷链物流“最后一公里”快速配送方法研究

冷链物流“最后一公里”的品质配送，对于实现全程冷链以及提升企业形象有着重要的意义。为了实现冷链物流的快速配送，本文提出了一种基于复杂网络的“最后一公里”物流配送区域划分方法。该方法构建了现实生活中物流配送的复杂网络模型，然后基于两阶段的LinkRank社区发现算法实现了物流配送区域的划分，最后建立了一套完善的物流配送体系。该体系明确了配送中转站以及配送点所覆盖的区域，这些区域所包含的社区物流关系紧密、易于配送。本文通过案例研究，验证了方法的有效性，最终方案可有效提高“最后一公里”的配送效率和降低物流成本。

Research on Rapid Delivery of "Last Mile" of Cold-Chain Logistics

The quality delivery of“last mile”of cold-chain logistics is of significance on achieving the whole cold-chain and improving the corporate image.A logistics distribution region partitioning method of“last mile”based on complex networks is proposed in this paper in order to realize the rapid distribution of cold-chain logistics.A complex networks model derived from the logistics distribution in thereal world is established by this method.Then,the logistics distribution regionpartition is realized based on the two-phase LinkRank community detection algorithm.Finally,a perfect logistics distribution system is founded.The coverage area of distribution sites and transfer station are clearly defined in this system.The communities closely connect with each other and easy to be delivery in thosearea.The effectiveness of the method proposed in this paper is verified throughcase study,and the final scheme can effectively improve the efficiency of distribution and reduce logistics distribution cost of the“last mile”.
