| 摘 要： | 对信息熵的相关性质进行研究，在 Pignistic 概率转换方法的基础上融合信息熵的性质提出信任函数概率逐步逼近的新算法，决策者根据决策需要可以设定逼近阀值，以此确定是否继续逼近，达到降低决策风险的目的，最后通过算例说明新方法的优越性。

| Abstract: | The correlation properties of the informations entropy are studied. Based on the conversion method of pig-nistic probability,the new algorithm of gradual approximation belief function is proposed by fusion on the nature of entropy. According to the need of decision makers can set the threshold,to determine whether to continue the algo-rithm,in order to reduce the risk of decision-making. Finally,the advantages of this method through examples are explained. |
