Combinatorial Growth Under Disruptions
Irregular operations driven by crew availability and tighter duty-time limits cause exponential growth in gate assignment combinations as flights, gates, and constraints interact.
Feasibility Limits of Classical Heuristics
With cascading delays and compressed schedules, classical algorithms frequently fail to produce feasible gate assignments at operational scales.
Constraint-Heavy Optimization
Minimizing gate idle time while enforcing strict non-overlap constraints becomes computationally intensive within fixed airport operating windows.
