Study on the Modification on DS Theory of Evidence Based on Evidence Support Level

To avoid the unreasonable evidence theory caused by the high conflict evidence, the modification on DS Theory of Evidence (DSTE) based on evidence support level is proposed in this paper. First of all, various modifications on DS theory of evidence are generally analyzed. On this basement, the novel conflict information weighted allocation method based upon evidence support level is presented in detail. It realizes the unification of subjective objective diagnostic knowledge and the uncertain information, which is able to settle the fusion failure caused by the evidence conflict.
