Xiaojuan Tang · Journal of Jiangxi Normal University · 2004
D-S evidence theory is a useful method for dealing with uncertainty problems. Because there exist shortcomings in its combination rule, it hasn't been successfully applied. This paper presents an improvement of combination rule. Not only may the combination result be acceptable if the evidences involved conflict with another one highly and the evidence's conflicting probability is distributed to every proposition according to its average supported degree, but it is also capable of handing related evidence focusing to the amount of information resident in piece of evidence. Experiments show that the new combination rule improves the reliability and rationality of the combination result.
