description: Complex systems are now integrating many sensors, physical or logical, in order to be able to take the best decision knowing the exosystem and endosystem. These sensors are data sources, which deliver partial information, imprecise and/or uncertain, partially complementary and partially redundant. The theory of belief functions is now widely used in data fusion because it provides a formal framework for the representation of both imprecise and uncertainty information. However, even modeling the ignorance and the imprecision of the sources, the source combination usually lets appear some disagreement/conflict between sources.A disagreement between sources makes the system unstable and can impact the decision. Thus, for managing the disagreement, several authors have developed different combination rules where the “Dempster's conflict” is transferred to a set of elements. A few works have proposed to consider the conflict as a piece of information exploitable beyond the scope of the combination. In this work, we aim at decomposing the Dempster's conflict in order to better interpret it. We propose a decomposition with respect to different assumptions simple or compound of discernment space. We show the uniqueness of this decomposition and we specify the algorithm, based on the canonical decomposition of belief function. We then interpret each term of the decomposition as the contribution, to global conflict, brought by each hypothesis simple or compound. This decomposition is applied to the analysis of intra-conflict source (i.e. the conflict inherent in the source) or inter-conflict sources (i.e. the conflict appearing during the fusion of sources). We illustrate on toy examples how observing the distribution of conflict with respect to different assumptions may allow the identification of the origin of some conflicts.Three applications of our measurement have been developed to illustrate its usefulness.The first application deals with the preventive detection of fal…
