Aiming at disadvantages in description of evidence conflict by only using conflict coefficient,from two combination factors point of view which are conflict coefficient and pignistic probability distance,in rectangular plane coordinate system defined by conflict coefficient and pignistic probability distance,the conflict is represent by the distance of point to the straight-line,then the conflict information is transformed into support information.After the evidence sources are modified by the weight coefficient,the Dempster' s combination rule is implemented.Examples analysis and comparison prove that the modified combination method of evidence has feasibility and superiority.
