基于BPAF判决的决策层目标属性融合研究

Research of the target characteristics fusion in the decision layers based on objector BPAF

在D-S证据理论框架下,研究了基于目标基本概率赋值(BPAF)判决的决策层目标属性融合问题。简要介绍了D-S证据组合理论框架,阐述了基于BPAF判决的决策层目标属性融合策略、步骤;分析了证据严重冲突时,Dempster证据组合规则不合理的本质原因;提出必须对D-S证据组合规则进行改善等需要继续深入探讨的几个问题。

Based on the target BPAF (basic probability assignment function) in D - S evidence theory,the target characteristics fusion problems in the decision layers had been studied.First, a few concepts of D - S evidence theory, D -S evidence combination rule and decisions method are briefly introduced, and the programs of D - S evidence combination rule based on BPAF is described. Second,the unfair reason is analyzed about D - S evidence theory when combing evidences with high degree of conflict; Last, some problems are deeply researched, e.g,modifying D - S evidence combination methods.
