Abstract: In order to solve the airport gate pre-assignment problem, stratified sequencing method in multi-objective programming is adopted to divide the gate assignment into two stages, and a gate assignment optimization model which coordinates different targets by priority is established. In the first stage, the optimization model is constructed with the objective of minimum number of soft conflicts under hard constraints. In the second stage, the soft constraint conditions are relaxed by the first stage assignment results, and the model is built with the highest gate occupancy rate and the best robustness of the pre-assignment scheme. A hybrid genetic algorithm for solving the assignment model is designed by combining genetic algorithm with greedy algorithm. According to the actual operation data of a large domestic airport, validity of the model and algorithm is verified by comparing with the results of CPLEX optimization, providing theoretical reference for coordinating various optimization objectives to solve the problem of gate assignment by priority.
