基于证据源和组合规则双修正的证据合成
Evidence Synthesis Based on Double Modification of Evidence Source and Combination Rule
摘要
Abstract
In view of the problems existing in the traditional evidence synthesis and the single correction improvement method,a new evidence combination method is proposed,which is based on the combination of evidence sources preprocessing and combination rules. According to the concept of included angle co-sine,the multi-dimensional vector distance formula is inferred. Evidence distances representing the con-flict degree are calculated using the evidence vector, which are further converted into the weight coeffi-cient. The evidences probability is redistributed by using the weight coefficient. Finally,the improved dy-namic synthesis rule is used to complete the combination of the evidence. At the same time,a new algo-rithm analysis model is proposed. The experimental results show that the algorithm has the best results, strong versatility and stability in the evidences combination,and it can be applied in information fusion,un-certain information decision-making and other fields.关键词
