Current investigations into urban aerial mobility, as well as the continuing growth of global
air transportation, have renewed interest in Conflict Detection and Resolution (CD&R) …

Computer-aided air traffic management has increasingly attracted the interest of the
operations research community. This includes, among other tasks, the design of decision …

Airline operations are subject to frequent disruptions typically due to unexpected aircraft
maintenance requirements and undesirable weather conditions. Recovery from a disruption …

We consider the air traffic conflict resolution problem and develop an optimization model for
generating speed trajectories that minimize the fuel expended to avoid conflicts. The …

This paper presents a supervisory algorithm that prevents side collisions among vehicles at
an intersection by taking control of vehicles when necessary. Based on the vehicles' current …

We consider the problem of aircraft conflict avoidance in Air Traffic Management systems.
Given an initial configuration of a number of aircraft sharing the same airspace, the main …

Air-conflict resolution is a bottleneck of air traffic management that will soon require powerful
decision-aid systems to avoid the proliferation of delays. Since reactivity is critical for this …

This paper proposes a taxonomy of conflict detection and resolution (CD&R) approaches for
operating unmanned aerial vehicles (UAVs) in an integrated airspace. Possible approaches …

We formulate fuel-optimal conflict-free aircraft trajectory planning as a hybrid optimal control
problem. The discrete modes of the hybrid system capture the air traffic procedures for …

The approach presented in this paper aims at finding a solution to the problem of conflict-
free motion planning for multiple aircraft on the same flight level with trajectory recovery. One …
