Conflict evidence DS combination method research based on Minkowski distance
Da Zhang · Journal of Sichuan University · 2012
One novel conflict evidence combination method based on evidence pretreatment was studied. The importance degree of the evidence were different,the directly combination conclusion of them may be opposed to the real.According to the different coefficients of Minkowski distance,absolute distance, Euclidean distance and Chebyshev distance were obtained,which have certain differences.The evidence distance was obtained through integration of the three distances,and represents a more accurate evidence relationship.Evidence distance was further changed into the weight which reflects the importance of evidence. According to weight,the basic probabilities were reallocated,and then were used to get the final combination result by the improved combination method.The superiority of the new method is shown by the different algorithms comparison example.
