基于物流场理论的物流生成及运行机理研究

随着现代物流规模的增大和物流所依托交通资源的日益社会化,物流运作形态呈现出物流源、物流迹线、物流节点、物流汇等各要素协调作用的系统效应,构成了物流场的演变形态.由于现代物流系统具备"场"的基本要素,具有明显的"场"的特征,可将场论引入物流研究领域,建立以需求力作为物流活动驱动力、以需求地作为激发场源的物流场理论.文章在物流场理论基础上,根据物流场势能、物流阻抗、物流场强等特征量的相互作用关系,推导出物流的生成机理及运行模型.研究结果表明,物流场理论能有效揭示物流活动的本质,物流生成的过程是动力、阻力相互作用的结果,在物流实践中,应尽量顺应物流场原理来设计、优化物流系统.一要安排物资在物流场势能相差最大的物流源、汇点之间流动,以保证物资价值得到最大程度的利用;二要尽量减小物流迹线中的物流阻抗,使物资流动过程损耗更小,物流活动更为高效顺畅.

Logistics Formation and Operation Mechanism Based on Logistics Field Theory

With the rapid increase of the logistics size and the socialization of the traffic resources which logistics is dependent on, the operation pattern of the logistics system gradually presents the associative field effect with the form of logistics sources, nodes, corridors and sinks. In order to make clear the essential characteristics of logistics, provide theoretical support for logistics practice, starting from the practical form and basic operation characteristic of the modern logistics, the authors intr...
