Abstract:

Aiming at the problem of not fully considering the heterogeneity of nodes in the equipment system network modeling process, a system effectiveness evaluation method based on node importance and improved information entropy is proposed. Firstly, the equipment system of system network model based on the operation loop theory and equipment layering method is buit. Secondly, the importance of nodes is comprehensively evaluated from the three aspects of the overall network, the network part, and the integrity of the equipment in wartime. Finally, based on the node weights and the number of node participation operation loop, a combat effectiveness evaluation model with improved information entropy is constructed. The bombing of the enemy's rear base combat system was analyzed as an example to verify the feasibility and rationality of the method.

Key words: operation system of system, operation loop, interpretation structure model, fuzzy evaluation, information entropy
