Abstract:

To address the scheduling problem of aircraft fleet support processes under limited resources, a fleet support process optimization model that covered multiple aircraft, activities, and resource constraints was developed. An activity node graph model was used to establish the temporal logic, resource competition, and other constraints in the fleet support process, forming a "time–activity–resource" multidimensional optimization model. A genetic algorithm based on priority encoding was proposed, incorporating a serial decoding strategy and a dynamic penalty function to handle the complex constraints in the model, efficiently solving the optimization problem under complicated temporal and resource constraints. A fleet support process simulation model was developed, and a discrete event simulation was performed to verify the effectiveness and adaptability of the optimized solutions. Simulation results demonstrate that the proposed method significantly reduces the fleet support time and improves the utilization efficiency of limited resources.
