Abstract

When evaluating the flight reliability of guided munitions, the results of using D-S evidence theory to fuse conflicting evidence will be biased. Aiming at this problem, an improved method of D-S evidence theory based on weighted Lance distance is proposed. The evidence is preprocessed first, and the weighted Lance distance is used to calculate the degree to which different evidence is supported by other evidence. The product of the credibility determined by the Lance distance and the uncertainty determined by the entropy weight is used as the fusion weight to modify the mass function, and then the D-S evidence theory is used to obtain the result. Finally, the method is compared with the traditional D-S evidence fusion theory and Bayes fusion theory. The results show that this method can more effectively fuse conflicting evidence than other methods and improve the accuracy of the reliability assessment of the flight reliability of guided munitions.
