The 20th and 21st joint COTA International Conference of Transportation Professionals (CICTP 2020-21)

The point merge system (PMS) aims to solve the sequencing and scheduling problem for the inbound traffic, which is currently handled by controllers. This study proposes a modeling method and a heuristic algorithm for arrival sequencing and scheduling problem by taking advantage of the particular structure of the PMS. Firstly, the structure and operational mode of the PMS were introduced. Secondly, the PMS based arrival sequencing and scheduling model was constructed considering the operational constraints (like safety separation, time windows) and objective functions (maximize capacity enhancement). Thirdly, a heuristic algorithm (Adaptive genetic algorithm based on elite strategy) was proposed to solve such a problem. Finally, the inbound traffic of Changsha Huanghua International Airport was taken into consideration to carry out the validation.
