Evaluation of Homogenization in Metroplex Operations Based on Multi-Dimensional Indicators

The development of a Multiple Airport Region (MAR) could lead to fierce competition. To evaluate the level homogenization between airports in MAR, evaluation method based on multi-dimensional indicators was developed. A indicator system is proposed that takes into account infrastructure, integrated support, operational efficiency and airline networks. Then Critic Delphi are used assign hierarchical weights for each dimension indicators. multi-layer matrix airport pairs within MAR derived. For with high comprehensive homogenization, suggestions provided according analysis This study paper selected three typical MARs internationally demonstrate advantage approach. homogenous coefficient (greater than 0.5) were analyze reasons causing homogeneity. Results show fusion captured characteristics MAR. Most New York London had strong differentiation route network layout, Greater Bay ambiguous division labor low network, except CAN SZX airports. Suggestions discussed separately mitigate homogeneity MAS, thus, improve operation performance MARs.
