To solve the imbalance problem of resource allocation of each link in the ground support process of transit flights, a support process equilibrium optimization model was proposed based on the systematic analysis of link business characteristics and equilibrium influencing elements. The link start time and resource usage were considered to constrain the priority and operation mode for good applicability. Based on the optimization objectives of minimizing the effective deviation, total operation time and comprehensive resource consumption of the links, a model objective function was established to measure the resource balance of each link in the support process. By NSGA-II algorithm with improved chaos and differential evolution, the optimization scheme of the constructed model was solved and designed with the actual operation data of a hub airport in central China. To verify the effectiveness of the model, the optimization scheme was evaluated based on the equilibrium evaluation index. The results show that the equilibrium optimization model is effective in terms of time utilization and resource allocation, and the total operating time is reduced by 10.6% with saving 30.3% of the total amount of idle resources. The evaluation shows that the equilibrium rate is increased by 10.7%, and the time loss coefficient and the resource smoothing coefficient are reduced by 65.7% and 54.7%, respectively.
