摘　　要：针对现有将基本概率赋值转换为决策概率方法的不足,提出一种基于确定度的决策概率转换方法。该方法根据基本概率赋值的特点,将单子集命题的基本概率赋值之和作为系统对命题的确定度,并用其对比例信度转换方法和比例似真度转换方法进行线性组合,得出命题的决策概率。通过算例对比新方法与已有方法,结果表明新方法更加合理有效。In order to overcome the drawbacks in current transformation methods of basic probability assignment to decision-making probability,a decision-making probability transformation method based on the certainty degree is proposed. According to the characteristic of basic probability assignment,the sum of each the Singleton proposition＇s basic probability assignments is regarded as the certainty degree of the system in this paper,and the decisionmaking probability of each proposition was achieved by linear combination,which is the transformation method of decision-making probability based on proportional belief and proportional plausibility. The proposed method was compared to the other usual methods with examples. The experimental results show that the proposed method is more reasonable and effective.
