Abstract: A method and device generate the path of a moving apparatus, within a predetermined time constraint, between a start and end points, the moving apparatus having predetermined movement constraints. The method includes: calculating a grid of a movement area of the mobile device, the start point and the end point belonging to the movement area, the grid being formed by a set of adjacent grid elements; calculating a cost map associating at least one cost value with each grid element; calculating, by a wavefront propagation method using the grid and the calculated cost map, a first integrated cost map associated with the point of departure and a second integrated cost map associated with the point of arrival; and determining a diverted path linking the points of departure and arrival via a detour point, using the first and second integrated cost maps.

Abstract: Disclosed is a method for determining tactical actions for protecting a reference entity with respect to a plurality of entities in a battlefield environment, the method including: segmenting the battlefield environment into a plurality of layers; associating actable deterrent systems with each layer; obtaining data representative of the probability, for each deterrent system, that the considered deterrent system deters an entity in the associated layer; providing, for each entity, the level of threat of the entity; and computing a cost function for determining the deterrent systems to be engaged by the reference entity for rendering extremal the cost function, the cost function being a function depending from the provided level of threat and the obtained data.

Abstract: Disclosed is a method for evaluating the level of threat of at least one entity among a plurality of entities in a battlefield environment, the level of threat being evaluated with respect to a reference entity to be protected, the method including the steps of: segmenting the battlefield environment into a plurality of layers; obtaining data representative of a position of the entity with respect to the layers of the battlefield environment; and determining the level of threat of the entity using the obtained data.

Abstract: A method for generating a taxi trajectory of an aircraft in an airport area includes the acquisition of a clearance including departure, arrival and intermediate elements of said area, the acquisition of a graph, and the determination, based on said graph, of entry and/or exit nodes for each element. It also includes the calculation, in the graph, of paths that are external to the elements and a path that is internal to each intermediate element, each external path connecting an exit node of one element to an entry node of the following element, each internal path connecting the entry node and exit node of said intermediate element, the paths calculated at first among the external and internal paths having a minimal cost; the calculation of a global path based on the internal path(s) and external paths and the generation of said taxi trajectory based on the global path.

Abstract: The method in accordance with the invention is a method according to which several decision criteria and a preference relation based on these criteria between the solutions of the problem are established. Modeling of the problem to be solved is established by obtaining solutions constructively via a tree search process. A tree search strategy has been established for each criterion. The strategies are alternated so as to find solutions of increasing quality; the strategies are chosen dynamically as a function of the last solution found. The alternation of strategies continues until a stopping condition is satisfied. The last solution found before the satisfaction of the stopping condition is exhibited as the solution to the problem set.
