快递网络构成「2019网络总结」

快递网络由节点和线组成，有整体性、层次性、适应性、复杂性的特点，组成要素包括呼叫中心、服务网点、分拨中心、运输路线，结构模式分为点点直达模式，即节点直接建立运输路线，单一轴辐模式中根据中心节点的数目分为单枢纽轴辐模式、多枢纽轴辐模式、混合轴辐模式。

Express delivery network is composed of nodes and lines, with the characteristics of integrity, hierarchy, adaptability and complexity, the constituent elements include call centers, service outlets, distribution centers, transportation routes, the structural mode is divided into dot direct mode, that is, nodes directly establish transportation routes, single-axis spoke mode is divided into single hub spoke mode, multi-hub hub spoke mode, hybrid hub spoke mode according to the number of central nodes.

快递网络有度分布、匹配形式、平均路径长度、聚焦系数社区结构、富人俱乐部结构特性，网络模型有WS小世界模型、BA无标度网络模型，行为指标有强度-度相关性、鲁棒性。

The express delivery network has a degree distribution, matching form, average path length, focus coefficient community structure, rich club structure characteristics, network model has WS small world model, BA scaleless network model, and behavioral indicators have intensity-degree correlation and robustness.

航空快递网络是小世界网络、单标度分布、不存在明显的社区结构、具有富人俱乐部现象、异配特性的结构特性，演化机制主要体现在增长、偏好两方面；陆运快递网络是小世界网络、无标度特性、有明显社区结构、具有富人俱乐部现象、节点度整体表现为异配特性，演化机制不仅包括增长、偏好两方面，也包括节点之间的地理位置。

Air express network is a small world network, single scale distribution, there is no obvious community structure, with the phenomenon of rich clubs, heterogeneous characteristics of the structure, the evolution mechanism is mainly reflected in growth, preference two aspects; the land express delivery network is a small world network, no scale characteristics, there is a clear community structure, with the phenomenon of rich clubs, node degree as a whole is manifested as a heterogeneous characteristics, the evolution mechanism not only includes growth, preference two aspects, including the geographical location between nodes.
