It serves as a key foundation for achieving mutual benefits and driving high-quality growth in the low-altitude economy. Based on the conceptual model of the urban air mobility industrial innovation ecosystem, the Lokta-Volterra symbiotic evolution model is introduced. Different symbiotic evolution patterns within the system are simulated. Taking the innovation ecosystem of the low-altitude air mobility industry in Shenzhen as an example, the grey estimation method is used to measure the coefficient of symbiosis. This method helps identify the symbiotic relationship of the subjects within the system and analyze the mechanism of symbiotic evolution of the subjects within the innovation ecosystem of the urban air mobility industry under different evolutionary stages. The results show that: (1) The symbiotic relationship between the symbiotic subjects is determined by the symbiotic coefficient. (2) The symbiotic relationships among system subjects vary at different stages. When the symbiotic coefficients are all greater than zero, the subjects reach a reciprocal symbiotic relationship. (3) The innovation ecosystem of the low-altitude air traffic industry in Shenzhen is in the transition stage from growth to higher-order growth evolution. The subject has experienced the evolution process of dual-subject competitive symbiosis, single-subject biased symbiosis, and dual-subject competitive symbiosis.

Then, a data-driven method is proposed to discover contributing factors to conflict priority assignment and obtain more realistic conflict resolution behaviors. Finally, the adaptive traffic situation and updated conflict priority approach are embedded into the proposed dynamic airport ground movement optimization framework. One month aircraft trajectory data is collected from a representative mega airport in China to illustrate the procedure. The results reveal that the dynamic control method could achieve better performance of airport ground movement than sequential approach through timely path-adjustment and effective collaboration with other aircraft. Moreover, the adaptive traffic situation approach could achieve better trade-off between computation efficiency and optimal solution, and the updated conflict priority approach tends to coordinate the taxiing aircraft to the route plan with lower additional taxi time and achieves a more balanced utilization of taxiway network.

In some busy airports, coordinators are responsible for allocating slots according to the priority order outlined by the WSG.

However, when airport capacity decreases, there may be situations where historical priority slots cannot be met, rendering the existing allocation guidelines ineffective. Currently, no research considers this situation. To complement the existing coordination priority, this paper first defines a new priority category from an operational perspective, referred to as operational priority. Furthermore, a weighted dual-objective slot optimization model is constructed, integrating both coordination priority and operational priority within the same optimization model framework. A constraint-based hierarchical search strategy is adopted to find the optimal results for different priority slots. Applying the model to Shanghai Pudong International Airport (ZSPD) in China, experimental results show that the proposed model can effectively meet the requests of airlines, with a slot adjustment amount of only 3.15% and a maximum displacement of fewer than 40 min.

Furthermore, most studies rely on multicriteria analyses with weights obtained through expert interviews, potentially introducing subjectivity. Therefore, this paper presents a unique approach: criteria and sub-criteria values in the AHP are determined by the results achieved in the SEM, providing a reliable scale of priorities among variables in the process of choosing a hub. The SEM tested two hypotheses that were supported by comparing two latent variables related to airport and region characteristics with another latent variable referring to aspects present in the activity of the dominant airline within each facility. Subsequently, an AHP was implemented, with criteria and sub-criteria weights based on the standardized loading factors and regression coefficients from the SEM, using sets of airports for each established world region in the study. Results indicated that airport characteristics, particularly those related to the passenger terminals, have a greater influence on the main carrier activity than region characteristics. A regional analysis revealed that in the Americas, Europe, the Middle East, and Africa, this predominance is even more pronounced, whereas in Asia-Pacific region, there is a contrary trend in which the socioeconomic factors of the city appear to be more important than airport infrastructure.

To ensure optimal safety performance, screening lines have a limited capacity of passengers they can handle. Thus, to prevent extended waiting times for passengers, airports can only adjust the number of simultaneously open check lines. The airport operator must establish optimal schedules for opening security checkpoints and allocating necessary staff.
