Secure Coordination for Vertiport Sequencing in Advanced Air Mobility
Jaehan Im, Filippos Fotiadis, Ufuk Topcu +1
Advanced air mobility operations will require reliable coordination mechanisms for managing dense traffic near vertiports. However, sequencing decisions may become vulnerable when…
Scalable Coordination with Chance-Constrained Correlated Equilibria via Reduced-Rank Structure
Jaehan Im, David Fridovich-Keil, Ufuk Topcu
Chance-constrained correlated equilibrium enables coordination of noncooperative agents under cost uncertainty through probabilistic incentive-compatibility guarantees. However, co…
Chance-Constrained Correlated Equilibria for Robust Noncooperative Coordination
Jaehan Im, Ufuk Topcu, David Fridovich-Keil
Correlated equilibria enable a coordinator to influence the self-interested agents by recommending actions that no player has an incentive to deviate from. However, the effectivene…
Noncooperative Virtual Queue Coordination via Uncertainty-Aware Correlated Equilibria
Jaehan Im, David Fridovich-Keil, Ufuk Topcu
Collaborative virtual queueing has been proposed as a mechanism to mitigate airport surface congestion while preserving airline autonomy over aircraft-level pushback decisions. A c…
Noncooperative Coordination for Decentralized Air Traffic Management
Jaehan Im
Decentralized air traffic management requires coordination among self-interested stakeholders operating under shared safety and capacity constraints, where conventional centralized…
Iterative Negotiation and Oversight: A Case Study in Decentralized Air Traffic Management
Jaehan Im, John-Paul Clarke, Ufuk Topcu +1
Achieving consensus among self-interested agents remains challenging in decentralized multi-agent systems, where agents often have conflicting preferences. Existing coordination me…
