Improved TOPSIS Based on IAHP and Entropy for Threat Assessment

Abstract

Aiming at the problem of threat assessment for ballistic missile, a comprehensive assessment method of ballistic missile based on Improved TOPSIS is proposed to assess and rank the threat of incoming ballistic missile, which provides the basis for early warning resource scheduling, development of interception strategy, implementation of fire interception and other operations. First of all, the paper analyzes the shortcomings of TOPSIS method, and improves it in two aspects: one is the improvement of data standardization, the other is the improvement of index weight calculation method. The experimental results show that, compared with the typical methods such as fuzzy set and Bayesian network, the comprehensive threat assessment method of ballistic missile in this paper is more scientific and reasonable.
