摘要
Abstract
To deal with the problem arising in using D-S combination rule for the combination of highly conflicting evidences,disadvantage of existing improved method have been analysed. So a new modified method is proposed,the new method has first calculated the evidence primary weight via similarity degree of evidence. Then the concept of the evidence weight discount coefficient is introduced,weight of conflict evidence times discount coefficient is calculated and the evidence weight to form an overall weight of evidence is marged into. Finally,D-S combination rules is used to combined the weighted average evidence. An example indicates that the new method can give the more reasonable combination results compared with D-S combination rule and the other modified methods.关键词
