Node importance evaluation in multi-platform avionics architecture based on TOPSIS and PageRank

Abstract In this paper, a node importance evaluation method for multi-platform avionics architecture oriented to collaborative task capability is proposed, aiming at the evaluation problem of node contribution under the air combat collaborator, focusing on the influence brought by collaborative task information activities, considering the charged relationship between nodes, link networking relationship, collaborative task style relationship, data information processing, storage mode, and other factors. The evaluation results mainly reflect the contribution and importance of nodes to collaborative tasks. First, the TOPSIS method was used to evaluate the overall contribution of nodes under different indicator scales. 2) Secondly, a PageRank evaluation method is proposed to reflect the node-pointing relationship. The comprehensive weight of nodes considers the rationality of TOPSIS and PageRank algorithms. 3) Finally, the information entropy method is used to evaluate the overall combat capability.
