Scheme comparison of new airport site selection based on lattice order decision making method in the integrated transportation system

Abstract

In view of the limited rational decision made by decision-makers in reality, multi-objective Lattice Order Decision Making is introduced in the new airport site selection and Lattice Order Decision evaluation index system is constructed. Based on the types of index, processed the index into dimensionless, Integrate decision-makers' subjective judgment and the data dispersion feature to calculate the relative weights of the evaluation index. Combined with Decision-making moment, calculate the value of comprehensive differences of the schemes, and realize the Lattice Ordering of the schemes. Apply this decision-making method to evaluate three sets of alternative airport site selection schemes in Chengdu. The outcome is consistent with the actual situation, which proved that the decision-making method is reasonable.
