【摘要】 根据物流外包业务的发展特点和规律,利用复杂网络理论,构建并分析了基于节点度和基于自适应的两类物流外包网络的演化过程,利用平均场理论分析了前者的度分布的近似形式以及平均路径长度和聚类系数,证明了该网络符合幂律分布,并且具有"小世界"和"高聚类"的特性;利用Matlab对基于自适应的物流外包网络进行模拟,统计了其度分布、平均路径长度和聚类系数,并且与NW小世界网络和BA无标度网络进行了对比,结果显示该网络同样较好地保持了复杂网络的基本特性,即"无标度"、"小世界"和"高聚类"。更多还原

【Abstract】 In this paper, in accordance with the characteristics and development pattern of the logistics outsourcing business, and using the complex network theory, we built and analyzed the evolutionary process of two types of logistics outsourcing network which were based on nodality and adaptivity respectively, and then used the average field theory to analyze the approximate form of the nodal distribution as well as the average path length and clustering coefficient of the former to prove that the network was following the power law distribution and that it had the characteristics of little world and high conglomeration. Next, using the Matlab program, we compared the NW little world network and the BA scaleless network and found that the network had also retained well the basic characteristics of a complex network.更多还原
