Conflict Evidence Combination Method Based on VIKOR

In the process of applying Dempster-Shafer (D-S) evidence theory to evidence fusion, it is often impossible to solve the serious conflict of evidence. This paper proposes a conflict evidence combination method based on compromise ranking method (VIKOR). Firstly, using the precedence order chart method to calculate the weight of each focus element, according to the weight to distinguish the type of index and standardized decision evaluation matrix. Secondly, determine the positive and negative ideal solutions of the standardized matrix, calculate group utility value and individual regret value. Finally, calculate the compromise decision index, it is inverted and normalized as a weight to correct the evidence source. The final result is obtained by using Dempster's rule of combination. Compared with other combination methods through experimental analysis, the effectiveness of this method is illustrated.
