Chapter 457. Belief function theory based decision support methods: Application to torrent protection work effectiveness and reliability assessment
Abstract : Civil engineering protection works mitigate natural risks in mountains, such as torrents.
Analysing their effectiveness at several scales is an essential issue in the risk management. Based on expert
knowledge, used methods have been developed under risky environment. However, decision is made under
uncertainty because of 1) the lack of information and knowledge on natural phenomena and 2) the het-
erogeneity of available information and 3) the reliability of sources.
In this paper, we propose to help decision-makers with advanced multicriteria decision making methods
(MCDMs). Combining classical MCDM approaches, belief function, fuzzy sets and possibility theories,
they make it possible decisions based on heterogeneous, imprecise and uncertain evaluation of criteria
provided by more or less reliable sources in an uncertain context. COWA-ER (Cautious Ordered Weighted
Averaging with Evidential Reasoning), Fuzzy-Cautious OWA or ER-MCDA (Evidential Reasoning for
Multi Criteria Decision Analysis) are thus applied to several scales of effectiveness assessment.
