Planning function is essential for increasing the autonomy of aerial systems. This paper presents some improvements dedicated to the management of degraded events in an existing control architecture. These events may start an online replanning. In a military observation mission context, a complex modeling and several efficient algorithms for planning are… (More)
In this paper, we show how genetic algorithms can be used to compute automatically a balanced sectoring of airspace to increase Air Traac Control capacity in high density areas 1. systems in high density areas by balancing load of sectors .
In this paper, we show how genetic algorithms can be used to compute automatically a traac assignment of aircraft on the air network to increase Air Traac Control capacity in high density areas.
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 contribution of this work is to develop three consistent models, i.e., from a continuous-time representation to a discrete-time linear approximation. Each of these models… (More)
Possibilistic and qualitative POMDPs (π-POMDPs) are counterparts of POMDPs used to model situations where the agent's initial belief or observation probabilities are imprecise due to lack of past experiences or insufficient data collection. However, like probabilistic POMDPs, optimally solving π-POMDPs is intractable: the finite belief state space… (More)
Qualitative Possibilistic Mixed-Observable MDPs (π-MOMDPs), generalizing π-MDPs and π-POMDPs, are well-suited models to planning under uncertainty with mixed-observability when transition, observation and reward functions are not precisely known and can be qualitatively described. Functions defining the model as well as intermediate calculations are valued… (More)
This article presents the integration of on-line mission planning and flight scheduling for an unmanned aerial vehicle in military observation missions. Planning selects and orders the best subset of observations to be carried out and schedules the observations while accommodating time windows. The vehicle is subjected to speed, fuel supply and flight… (More)
