Méthode d’aide à la décision basée sur un raisonnement évidentiel pour évaluer l’efficacité d’un ouvrage torrentiel de stabilisation

Abstract : Assessment of structural, functional and economic effectiveness of civil protective works against natural hazard, such as torrential check dams, is a key issue for infrastructures assets owners and managers such as French government who owns many of them. This assessment relies on imperfect information (imprecise, incomplete, uncertain), provided by several sources, which relates as far to structures themselves than to natural phenomena scenarios. Decision-aid methods in uncertain contexts, coupling fuzzy sets, possibility and belief function theories (notably ER-MCDA and FCOWA-ER) are used to assess protective single works and devices effectiveness indicators. Information fusion considers multiple more or less reliable sources and combine them together in order to help decision-making (choosing, sorting or ranking alternatives). This paper describes their principles and demonstrates their interest for helping the assessment of torrent check dam functional effectiveness assessment in an environment of high uncertainty.
