This paper describes a novel optimization-based approach to conflict resolution in air traffic control, based on geometric programming. A key feature of this approach is its ability to also take into account various metering directives issued by the traffic flow management level, in contrast to most methods that focus purely on aircraft separation issues. Moreover, the proposed methodology can account for some of the nonlinearities present in the formulationsofconflictresolutionproblems,whileincurringonlyasmallpenaltyincomputationtimewithrespectto the fastest linear-programming-based approaches. Integer variables can be introduced to improve the quality of the solutions and to include combinatorial choices, for example, to optimize over aircraft sequences in merging streams. Simulation results demonstrate the efficiency of the approach on various aircraft separation problems, including miles-in-trail and minutes-in-trail restrictions through airspace fixes and boundaries.read more

Conflict resolution problems for air traffic management systems solved with mixed integer programming
TL;DR: This paper proposes two different formulations of the multiaircraft conflict avoidance problem as a mixed-integer linear program: in the first case only velocity changes are admissible maneuvers, in the second one only heading angle changes are allowed.

3-D Decentralized Prioritized Motion Planning and Coordination for High-Density Operations of Micro Aerial Vehicles
TL;DR: This paper presents a decentralized motion planning method for multiple aerial vehicles moving among 3-D polygonal obstacles resembling an urbanlike environment that combines a prioritized $A^\star$ algorithm for high-level planning, along with a coordination method based on barrier functions for low-level trajectory generation and vehicle control.

Graph Implementations for Nonsmooth Convex Programs
Michael C. Grant,Stephen Boyd +1 more
TL;DR: Graph implementations as mentioned in this paper is a generic method for representing a convex function via its epigraph, described in a disciplined convex programming framework, which allows a very wide variety of smooth and nonsmooth convex programs to be easily specified and efficiently solved.

TL;DR: A survey of 68 CDR modeling methods, several of which are currently in use or under operational evaluation, and a framework that articulates the basic functions of CDR is used to categorize the models.
Conflict resolution for air traffic management : a study in mutiagent hybrid systems
TL;DR: In this article, the authors present a method to synthesize provably safe conflict resolution manoeuvres for free flight, in which aircraft choose their own optimal routes, altitudes, and velocities.
