D numbers theory:Dempster-Shafer理论的推广

D numbers theory: a generalization of Dempster-Shafer theory

Xinyang Deng, Yong Deng

摘要:

Dempster-Shafer理论因其表达不确定性信息的能力而被广泛应用于不确定性建模和知识推理。然而,由于存在着一些条件,如排他性假设和完备性约束等,在很大程度上限制了它的发展和应用。为了克服Dempster-Shafer理论的这些缺点,提高其对不确定信息的表达能力,本文系统地提出了一种新的理论--D数理论。在该理论中,不确定信息用D数表示,信息的推理和综合由D数组合规则实现。提出的D数理论是Dempster-Shafer理论的推广,继承了Dempster-Shafer理论的优点,增强了其不确定性建模能力。

英文摘要:

Dempster-Shafer theory is widely applied to uncertainty modelling and knowledge reasoning due to its ability of expressing uncertain information. However, some conditions, such as exclusiveness hypothesis and completeness constraint, limit its development and application to a large extend. To overcome these shortcomings in Dempster-Shafer theory and enhance its capability of representing uncertain information, a novel theory called D numbers theory is systematically proposed in this paper. Within the proposed theory, uncertain information is expressed by D numbers, reasoning and synthesization of information are implemented by D numbers combination rule. The proposed D numbers theory is an generalization of Dempster-Shafer theory, which inherits the advantage of Dempster-Shafer theory and strengthens its capability of uncertainty modelling.
