Abstract: In order to improve the scientific airport slots allocation, Borda count method of the social choice theory is applied to the decision making of the slots allocation. Taking Beijing Capital International Airport as an example, the paper builds an evaluation index system in terms of market scale, operational efficiency, market potential and policy factors and determines the index weights by analytic hierarchy process model. The paper establishes a Borda model for slot allocation and applies numerical example to verify the feasibility of the model. The result shows that the established slots allocation model is scientific and rational. The decision-making process and decision outcomes can be improved effectively by the Borda count method applied to slots allocation.
