Abstract: To address the limitations of "small sample size and poor information" in the winter operation efficiency evalua鄄 tion of airport electric tractors, this paper first constructs an efficiency evaluation index system. Secondly, a com鄄 bined weighting method integrating the analytic hierarchy process (AHP) and the entropy weight method is em鄄 ployed to determine index weights. These weights are then incorporated into a grey clustering analysis model to evaluate the winter operation efficiency of airport electric tractors. Finally, an empirical analysis is conducted based on actual winter operation data of airport electric tractors from an airport in Northwest China. The results demonstrate that the proposed method can accurately evaluate the winter operation efficiency of airport electric tractors, verifying its effectiveness and applicability.
