Abstract :
The Dempster-Shafer evidence theory (DST) is widely used in many fields of information fusion. However, counter-intuitive results may be obtained by the classical Dempster combination rule (DRC) when collected evidences conflict highly with each other. However, Haenni gave confutation based on Zadeh´s criticism of DRC, reasons for conflict between evidences concluded by him were not comprehensive. So, reasons for conflict between evidences are analyzed and summarized in this paper, that is, sensor reliability, incompleteness of the frame of discernment which is also called imprecise definition of GBBA model, and integration results of the above two reasons are the material reasons for conflict.
