The existence of the evidence of weak decision making in combination of evidence may lead to counter-intuitive results even under the condition of low conflict. To solve this problem, this paper proposes an evidence combination method based on decision distance correction. Firstly, the definition of weak decision-making evidence is proposed. A new measure called decision distance is proposed, which can describe the decision of one evidence and the difference between weak decision-making evidence and other evidences more effectively by using Jousselme distance. Then, two different discounting factors are provided by identifying whether weak decision-making evidence and "one ticket veto" evidence exist at the same time or not, which can effectively expand the difference of discounting factors of the majority of evidence and those of other evidences, so that the effect of "one ticket veto" evidence is weaken. Finally. Dempster fusion rule is used to combine the revised evidence. Multiple experiments show that, the proposed evidence combination method can well solve the problem of weak decision evidence fusion, and the fusion result has rapid convergence rate and can make more reliable decisions with low uncertainty, which is a good complement to existing research.
