Abstract: This paper presents a general math expression of step by step combination results for evidence combination problem, and studies the theoretical rationality of step by step combination method and the convergence of the combination results. The step by step combination algorithm mixing Dempster evidence combination formula and the weighted average method is proposed for combination of severe conflicting evidence. The corresponding combination formula is selection and used according to the preset threshold of conflict. The simulation results show that the proposed algorithm has simpler calculation process and better convergence effectiveness than representative alternative rules.
