Abstract: Aiming at the problem of networked ammunition attack decision-making, an algorithm of networked ammunition attack decision-making based on AHP-TOPSIS was presented. The key attributes affecting the networked ammunition attack decision-making were analyzed. The AHP algorithm was used to construct the hierarchical structure, the judgment matrix was constructed and the weights of the attributes were determined. Then, the improved TOPSIS algorithm was used to get the ranking result of the decision scheme. The simulation results show that the algorithm has the advantages of low computational complexity and high real-time performance. The proposed algorithm can effectively solve the multi-node attack decision-making problem, and effectively restrain the algorithm from reverse order, and has certain robustness and practicability.
