A New Discounting Approach to Conflict Information Fusion Using Multi-criteria of Reliability in Dempster-Shafer Evidence Theory

Dempster-Shafer evidence theory (DSET) is an important tool to combine uncertain and imprecise information from multiple sources. However, when combining information with highly conflict, it will lead counterintuitive results. A lot of research has been done to resolve the problem. In this paper, we focus on the approach to revise the basic probability assignment of information (evidence) through discount factors. Two methods are proposed to computer discount factors by multi-criteria of reliability measurement. Then we combine multi-source information in the improved Dempster's rule. Finally, some numerical examples are used to illustrate the efficiency of our proposed methods.
