Embodiment Construction

[0016] The specific embodiments of the present invention are described below so that those skilled in the art can understand the present invention, but it should be clear that the present invention is not limited to the scope of the specific embodiments. For those of ordinary skill in the art, as long as various changes Within the spirit and scope of the present invention defined and determined by the appended claims, these changes are obvious, and all inventions and creations using the concept of the present invention are included in the protection list.

[0017] Since the rail transit industry chain is a double-chain structure, that is, the rail transit engineering construction industry chain and the rail transit product industry chain, if only a single-layer complex network is used to build it, the relationship between the two sub-chains cannot be well reflected. Therefore, the multi-layer complex network theory is adopted to construct a complex network for the two sub-chain...

Abstract

The invention discloses a method for configuring a rail transit industry chain based on a multi-layer complex network. Based on the multi-layer complex network theory, the SpaceL method is used to establish a dependent multi-layer complex network topology structure of a weighted rail transit industry chain. Attack and random attack, attack the nodes and edges in the network respectively, and select the corresponding evaluation indicators, use the entropy weight method to determine the weight of each index, and analyze the change trend and correlation of network performance under the attack on the edge and point. Characteristic performance, analyze and determine the relative importance of nodes and edges in the rail transit network, and finally use the weighted node contraction method to obtain its key nodes, and analyze the changing trend of important nodes in the network under the condition of continuous increase in investment, so that Provide corresponding decision-making support for the rational allocation of the rail transit industry chain.

Description

technical field [0001] The invention belongs to the technical field of rail transit industry chain configuration, and in particular relates to a rail transit industry chain configuration method based on a multi-layer complex network. Background technique [0002] With the continuous upgrading and development of the rail transit industry chain, it has gradually become a complex network structure. Enterprises interact and restrict each other, showing a certain complexity. Improving the overall network performance of the rail transit industry chain and rationally allocating various production factors and functional links in the rail transit industry chain have become urgent problems for the rail transit industry to solve. The industrial chain itself is a complex network structure. Applying the complex network theory to the research of the industrial chain is of great significance for enriching and deepening the theory of the industrial chain and improving the overall performanc...
