A novel air combat target threat assessment method based on three-way decision and game theory under multi-criteria decision-making environment

Threat assessment of air combat target (TAoACT) is an important issue in air combat decision-making. Current methodologies for threat assessment are insufficient in capturing the systematic and time-sensitive characteristics of air combat, lacking a comprehensive analysis for the complex threat of air combat target (ACT). To address this issue, we propose a multi-criteria three-way decision-making (MCTWD) method based on game theory for TAoACT. The proposed method comprises three key components: (1) a single-criteria three-way decision (TWD) model based on the relative utility function with a new multi-criteria attribute system; (2) a multi-criteria aggregation mechanism based on game theory to analyze and integrate diverse decision outcomes derived from various criteria; and (3) decision conditions based on joint criteria to rank and classify ACTs. The effectiveness and applicability of the proposed method have been validated through three numerical examples. Comparative analysis results indicate that the proposed method demonstrates superior performance in ranking and classification when compared to five widely-used MCTWD methods. [Display omitted]
