Abstract
In this paper, we construct a regional logistics model from a macroperspective. First, based on the gravity model, the index of logistics attraction between cities is established as the weight of the model, and hence the regional logistics weighted model is constructed. Next, we use the social network analysis method to analyze its structure and make specific recommendations for the construction of logistics networks. Finally, we analyze the model’s response to random attacks and deliberate attacks. From our study, it is found that when the failure nodes or edges reach a certain percentage, the regional logistics network will collapse on a large scale. Therefore, it is important to optimization the threshold of the regional logistics network. This clearly provides a new perspective for the study of the regional logistics networks.
Highlights
With the rapid development of e-commerce and the increasing close cooperation between enterprises, the logistics industry has become the focus of attention from all walks of life
The location of the logistics center problem has been studied from the perspective of covering problem [6,7,8,9] and fixed-charge facility location problem [10,11,12,13]. e layout of the regional logistics network is mainly modeled as a hub-and-spoke network, where the logistics center is the “axis” and the logistics connections with other nodes are the “spokes”
Our study was mainly focused on the construction of regional logistics network and the development of robust optimization
Summary
With the rapid development of e-commerce and the increasing close cooperation between enterprises, the logistics industry has become the focus of attention from all walks of life. E layout of the regional logistics network is mainly modeled as a hub-and-spoke network, where the logistics center is the “axis” and the logistics connections with other nodes are the “spokes” Such networks are studied to achieve minimum cost or optimal transportation efficiency [14,15,16,17,18]. Such an investigation provides a new approach to construct the regional logistics weighted network model On this basis, combined with complex network theory, the statistical properties and topological structure of the regional logistics weighted network are discussed, the stability and robustness of the network are analyzed, and a more stable topological structure model of the regional logistics network is found.
