Fusion of sources of evidence with different importances and reliabilities

Abstract : This paper presents a new approach for combining sources of evidences with different importances and different reliabilities. Usually, the combination of sources of evidences with different reliabilities is done by the classical Shafer's discounting approach and very often the taking account of different importances of sources, if any, is done with a simliar discounting way by assimilating the notion of importance with the notion reliability. These two notions are actually different and appears fundamental in most of hierarchical Multi-Criteria Decision Analysis (MCDA) problems, and thus they must be treated differently. We show in this paper how this can be done and we provide simple examples to show the differences between both solutions for managing importances and reliabities of sources. We also discuss the possibility for mixing them in a global fusion process.
