试论物流系统的网络模式

1 物流的网络概念 从系统论的整体观念来看,可以将物流系统看作网络结构来进行研究,用流和积累等流机理来进一步掌握和控制网络。这种网络结构一般至少有一个源(发点,如油井、油库、车站、港口和计算中心的处理机等)和一个汇(收点,如炼油厂、另一个输送站和计算机通道等),网络中有多条支路,各支路的交点称为网络节点(如输油线上的阀门,计算机系统中的门电路等),每一对收发点间都有许多带方向的动态连线,以表示两点间的运动路线。相对静止的节点和动态的连线,构成一个系统网络。

A Discussion on a Model for Logistics Network

A basic model for logistics network is proposed using the system theory and lux mechanism of fluid dynamics.It is pointed out that the logistics network is a mesh type structure constructed with many static in-out junctions, dynamic lines and a net-orientated set of information flow networks. The main problem in the study of a commercial logistics network is to determine the places, scales and numbers of plants, storehouses, transfer stations and retail stations while that of the logistics network of an enterprise is to determine the places, scales and numbers of plants, workshops, warehouses, machines and equipments, logistics channels, import and export.Problems that deserve attention in establishing a logistics network and junctions are discussed with the reality in China taken into consideration.
