一种基于成长的物流网络建模方法研究及实证分析

分析了当前流行的物流理论及其建模方法，结合复杂网络理论的最新应用，提出了一种基于成长特性的物流网络基本建模方法NGM。在建模的过程中，首先建立了一个原始模型，考虑到实际物流网络具有的成长特性、优先连接特性、赋权路径特性等方面的实际情况，在原始模型的基础上对该模型进行了修正和优化。结合物流配送中心的需要对该模型的一些特性进行了分析，最后给出了本模型的仿真实证结果。实验结果表明：基于NGM的物流网络能够按照节点的富集程度，形成了“一个核心节点，少量中心节点，大量外围节点”构成的层次型物流网络结构。该结构在经济性、时效性、安全性、沟通性和方便性方面都能使网络的性能达到最优状态。该模型对于物流网络的建模分析、系统设计和网络管理提供了一种新的思路和优化方法。

Study on Growth-based Logistics Modeling Method and Demonstration

Based on the analysis of the popular logistics theories, modeling methods and the newest application of complex network theory, a basic logistics network modeling method named NGM is presented. Firstly, a basic model is put forward in the paper, then according to some special characteristics of the real logistics network such as growth, preferential attachment, edge-weighted, the basic model is emended, improved and optimized. The demonstration is applied to analyze the selecting method of the logistics center. The results show that the hierarchical structure of “a key node, a small mount of center nodes, and a large mount of branching nodes” can be obtained in the model, which is the result of optimal selection in the whole network, and the model has some advantages in economy, timeliness, secrecy, communication and convenience contrasting the traditional logistics theories. The model gives us a new thought and optimal way of modeling analysis, system designing and network management of logistics network.
