Abstract Dempster-Shafer (D-S) theory of evidence is one of the main methods of decision fusion, but typical D-S theory is sensitive to high conflict evidences. A method based on the pretreatment mode is presented. The basic probability assignments of conflict focal elements are partly transferred to the union of focal elements before the Dempster combination rule is used. The combination order is determined based on the conflicted measurement. Therefore, D-S theory could deal with the cases with high conflict evidences since conflict information is translated into unknown knowledge representation.
