Abstract:
Aiming at the problem that the Reliability of Evidence Source(RES) is only derived from objective evidences but ignoring the subjective cognitively information such as knowledge, experience or intuition in RES reasoning and evidence combination, this paper introduces the RES objective matrix and the RES subjective matrix to reflect the objective and subjective RES information based on evidence distance and pair- wised judgment matrix. An integrating RES model for deriving overall RES information is established by minimizing the whole adjusting errors, and evidence reasoning steps are proposed by using Dempster combination rules. Numerical value example proves the feasibility of this method.

摘要： 现有证据理论研究侧重于从客观证据中提取证据源可靠性(RES)信息，而未考虑知识、经验、直觉等主观认知信息对RES推断及证据融合的积极作用。为此，基于证据距离和两两比较判断矩阵，提出反映证据源相对可靠性的主客观RES矩阵，以调节总误差最小为目标函数，构建用于提取证据源综合可靠性信息的RES整合模型，并结合Dempster组合规则给出证据推理步骤。数值实例验证了该方法的可行性。
