Abstract: As traditional multiple source information fusion system based on D-S evidence theory can not measure conflict and solve other problems,a conflict-measurable multiple source information fusion system was presented．Firstly,we presented a method which takes subjectivity and objectivity into consideration to get BPA based on decision-making table．Secondly,we defined a conflict measure based on conflict value and consistent value followed in the conflict matrix and consistent matrix．Next,we determined the weight value of the evidence in the combination rules based on the avera-ge conflict value of the evidence with others．Finally,we made full use of information produced from conflict evidence,and presented a new combination rules based on conflict information．Simulation experiment shows that the conclusion obtained by the fusion method is not only in accordance with human logical reasoning,but also reduces the uncertainty of the conclusion greatly.
