我国农产品物流网络分析与重构

Analysis of the Farm Products Logistics Network Structure and Reconstruction of China Based on the Directed Graphs Theory

本文对我国现阶段农产品物流网络结构进行系统分析,从物流场所出发,用系统模型描述了系统的状态,构建了我国现阶段的物流系统有向图,以此为工具,估算了有向图的流量及损失,分析了农产品物流损耗的影响因素。在此基础上,充分考虑农产品物流面对的各种环境,重新构建了包括逆向物流在内的降低农产品物流损耗的物流系统有向图,为提升我国农产品物流系统功能提出建议。

This paper analyses farm products logistics of China today systematically and shows the system＇s condition with system model.The directed graphs is constructed about farm products logistics system at present.At the same time,we estimate flux and loss of the directed graphs and analyse the factors of loss.Then a new farm products logistics system directed graphs is constructed including reverse logistics,which can reduce the loss of farm products logistics efficently.The paper is anticipated to provide some references for the function promotion of present farm products logistics system in China.
