Abstract：In this paper,the shortage of D-S evidence theory as well as its modification are analyzed,then a new combination method based on degree of gray relationship is proposed.The method uses degree of gray relationship as evaluation criteria,then regards each piece of evidence as discrete points and computes the similarity between every two evidences in evidence collection.Then the obtained similarity which represents the importance of evidences is normalized.The similarity obtained above is regarded as the weight of every evidence and generate new evidence model.Finally fusion result is got by means of evidence model.The numerical examples show that the method proposed in this paper compared to other methods has following advantages,including fast convergent rate,simple calculation method,easy realization in a project.
