考虑位置信息的物流配送网络节点重要性评估

网络化和信息化的发展使得物流配送变得日益复杂和庞大。对于一个配送节点而言,它除了满足给需求者提供货运物流,还会出现给其他配送节点提供货物调配运输的情况。在整个物流配送网络中,每个配送节点的关键性就会由多种影响因素共同作用。借助总强度法,结合信息论和网络复杂特性,综合考虑节点间的货运互信息量和位置信息,提出了一种新的适用于有向加权物流配送网络的节点关键性评估方法。并在小规模的加权网络中对该方法和已有的方法进行对比分析,证明该方法中的有效性和可行性,计算简单,更有利于细化各节点关键性。

Evaluation for Critical Node in Logistics Distribution Network Involved with Position Information

Networking and informatization make logistics distribution more complex and larger. As far as one distribution node is concerned, it provides goods transportation for demanders in time. By the way, it also can finish cargo deployment and united transit. So, in the whole logistics distribution network, the criticality of each distribution node can be effected by multi-factors. In this paper, based on total strength method, considered information theory and network complexity, combined with multi- information and position information of each node, it proposes a new evaluation method for critical nodes in a directed weighted network of logistics distribution. Finally, it is tested in a small-scale network and contrasted with other former methods through examples. And it is proved the new method valid, feasible and easier computing that can be useful to distinguish the criticality of each node.
