The thesis puts forward an improvement method for the combination rule of Dempster-Shafer evidence theory based on the reliability of evidence and the correlation between evidences. Different from D-S theory, two key parameters are introduced, one is the reliability of evidence, and another is the correlation coefficient between evidences. By weighting the evidence based on its reliability, the negative effect of unreliable evidence is reduced. By decreasing the probability evaluation of certainty and increasing the probability evaluation of uncertainty, the effect of correlative evidence to fusion result is reduced too, and then we can get better fusion result.
