Abstract

The invention relates to a flow network key node identification method and device based on multi-attribute information fusion. The method comprises the following steps: constructing a node flow network according to a to-be-identified event; obtaining a maximum flow counting index, a minimum cut counting index and a maximum flow centrality index of each node in the node flow network; constructing an identification framework of node importance in the node flow network; respectively calculating basic probability assignment functions corresponding to the maximum flow counting index, the minimum cut counting index and the maximum flow centrality index in the identification framework; fusing the basic probability assignment functions corresponding to the maximum flow counting index, the minimumcut counting index and the maximum flow centrality index to obtain importance indexes of the nodes; and sorting the nodes in the node flow network according to the importance indexes, and determiningkey nodes in the node flow network according to a sorting result. By adopting the method, the accuracy of key node identification can be improved.

Description

technical field [0001] The present application relates to the technical field of flow networks, in particular to a method and device for identifying key nodes of flow networks based on fusion of multi-attribute information. Background technique [0002] In the real world, our lives are dominated by a large number of networks. Flow networks can represent many models, such as oil in a pipeline, electricity in a high-voltage line, or data in a computer network. Network flow can also solve many problems, such as how to control road traffic in order to effectively alleviate morning peak congestion; in logistics network transportation, how to minimize channel costs while satisfying supply and demand; when bombers carry out bombing missions, How to deal a more serious blow to the enemy's supply lines. [0003] At present, the evaluation of the importance of nodes in flow networks is defined by the edges connecting nodes, such as in-degree, centrality, etc. However, identifying k...
