Shujin Pu, Lei Yang, Shenyuan Yang, Weiwei Hu · 2006
According to the insufficiencies existing in Dempster-Shafer theory of evidence when it deals with the conflicting evidences, many scholars have presented modified rules based on reallocation of the basic probability assigned to conflict. A new combination rule is presented to mend the disadvantages of the rules. This rule analyzes the validity of evidence set according as the extent of conflict with the use of the reliability of evidential sources and support measure of the evidence, and realizes information fusion rationally. Experiments shows that the new combination rule overcomes the limitations, and the outputs are constringent on the aspect of rationality, which enhances robustness of systems effectively.
