A Threat Assessment Method Based on Prioritized Visibility Graph Ordered Weighted Averaging Operator

Multi-target threat assessment is a considerable issue of air combat tactical decision. As the conventional approaches are deficient and imperfect in the procedure of determining the attribute weights and result display of the threats, a novel threat assessment method based on Prioritized Visibility Graph Ordered Weighted Averaging (PVGOWA) operator is proposed. In this work, the relative threat function and the multi-target assessment model of air combat are established. The VGOWA operator is used to calculate the objective weights, which can fully utilize the information in the combat situation. In order to avoid the randomness and uncertainty of expert scoring in the subjective weight determination process, the POWA operator is used to get the final attribute weights by fusing the objective weights and the priorities of the attributes of each target, which are identified by the decision maker. Besides, the radar-chart model is adopted to display the assessment results. Simulation indicates that the proposed method is more reasonable and intuitional for multi-target threat assessment compared to the conventional method.
