To reasonably assess the operational status of air traffic control (ATC) equipment and provide a reference for its maintenance and upkeep, a method for assessing the operational status of ATC equipment based on D-S evidence theory is proposed. Firstly, the relevant knowledge of D-S evidence theory is introduced. Then, an operational status level assessment standard that conforms to the reality of ATC equipment is constructed. Following that, initial evidence for each assessment indicator is constructed based on the membership function, and the evidence conflict is comprehensively measured using evidence distance and conflict coefficient, and then perform discount correction and integration. Finally, the rationality of the proposed method is verified through experiments, which can provide a reference for related research.
