【摘要】：系统研究了近年来关于D-S证据理论合成规则的相关成果,提出一种新的基于证据可信度的合成方法,并就解决证据合成悖论的有关问题做了必要讨论.鉴于Dempster规则处理冲突的不足及修正原始证据模型方法的可靠性,决定在分配冲突的同时应对证据模型进行修正,实现两者紧结合,在对一致性证据的"与"运算合成问题上,以及证据冲突在各合成命题的比例分配问题上,均有效利用了各证据的可信度等全局信息.实验结果表明:该方法在证据一致和高度冲突的情况下均表现出良好的适应性,具有较快的收敛速度和高可靠性,明显优于同类其他合成方法,可应用于多源信息融合、模式识别、不确定信息决策等领域.
[Abstract]:This paper systematically studies the relevant achievements of D-S evidence theory synthesis rules in recent years, puts forward a new method based on evidence credibility, and makes a necessary discussion on solving the paradox of evidence synthesis. In view of the deficiency of Dempster rule in dealing with conflicts and the reliability of the method of modifying the original evidence model, it is decided that the evidence model should be modified while the conflict is allocated, so as to realize the tight combination of the two methods, and to solve the problem of "and" operation synthesis of consistent evidence. And the evidence conflict can effectively utilize the global information such as the credibility of each evidence in the problem of proportion distribution of each synthetic proposition. The experimental results show that this method has good adaptability in the case of consistent evidence and high conflict, and has faster convergence speed and higher reliability. It is obviously superior to other similar synthesis methods, and can be applied to multi-source information fusion. Pattern recognition, uncertain information decision-making and other fields.
