An evidence combination rule based on the support degree of focal element

According to the management and assignment of conflicted evidences in the evidence combination, the paper introduces the supporting degree of focal element of conflicted evidences to the combination rule according to these issues, and suggests a new way of combination assignment. Based on the support degree of focal element, we establish a combination rule of evidence theory. Besides, the paper also gives the strict demonstration and makes simulated experiments of the new rule. The new rule rationally assigns the probability of conflicted evidences to every focal element according to the support degree. The experiments show that the results of the new combination rule are very reliable and rational.
