Some viewpoints about the optimization of the management of detection resources for the search of a moving target

We present here various point of views about the optimization of search effort for detecting a target. An important aim is to show the diversity of possible approaches. Algorithmic difficulties are emphasized. Various modelling are also considered as well as their implications for defining and solving the search problem.On expose ici quelques aperçus sur l'optimisation de la répartition des efforts de recherche d'une cible. Il s'agit de mettre en évidence la diversité des approches proposées. On examine plus particulièrement les difficultés algorithmiques. Diverses modélisations du problème sont aussi considérées
