Urban Air Mobility (UAM) requires a planning framework that captures how operational decisions shape passenger behavior and how behavioral responses feed back into service performance. Many UAM fleet planning studies treat demand as exogenous, so their models cannot represent behaviorally stable operations under changing supply conditions.
This thesis addresses this gap by developing a framework that internalizes endogenous demand--supply interaction and targets a behaviorally consistent operating point. This thesis proposes an iterative optimization framework that jointly updates demand, service frequency, and fleet deployment until the system reaches an equilibrium consistent with passenger choice behavior. The framework integrates hub-and-spoke network design, demand estimation based on service attributes, and fleet mix optimization with integer-feasible deployment decisions. The framework ensures numerical stability through attribute-level smoothing and behavioral waiting-time tolerance, and it avoids convergence heuristics that rely on relaxing integer constraints.
A case study in the Seoul Metropolitan Area compares compact and expanded vertiport networks and evaluates impacts on service frequency, fleet efficiency, and operational robustness. The results show that heterogeneous and route-specific aircraft deployment reduces demand oscillations across iterations and sustains reliable service levels across routes with different distance and demand profiles. Overall, the proposed framework provides a scalable basis for early-stage UAM network design and operations by explicitly internalizing demand--supply feedback.
