基于节点环的物流网格配送方法

为解决网格之间的物流配送问题,研究了有容量节点在物流配送中的调节作用,提出使用带扩展的有节点环流的NIO网络流模型。首先扩展网络节点,节点由入点、出点、中转弧和节点环组成;接着根据NIO网络模型特点,改进了流量守恒约束条件,给出了控制网络流的弧容量配平算法;最后对配平后的网络使用最大流算法,生成网格间的物流分配优化方案。计算得出物流通过节点环流调配后的增强效果。

Logistics Distribution Method Based on Network with Node Loop

To deal to solve the logistics problem between the grid capacity nodes in the logistics and distribution regulation, proposed with an extender node loop NIO network flow model. The first extended network node that is consist of inflow node, outflow node, transit arc and node loop; Then according to the NIO the network model, the flow conservation constraints conditions improve, the arc capacity balancing algorithm is put forward to control network flow; Finally, trim network using the maximum flow algorithm to generate the the logistics distribution between the grid optimization program. By calculating the distribution of the increasing effect is generated from the deployment flow of node loop.
