【摘要】 在处理不确定信息的方法中,D-S证据推理性能突出,应用广泛。但也存在决策方面的困难,事实上,有效的决策方法仍是它未解决的问题之一。该文从两方面研究了这一问题。首先根据测度论中代数(域)扩张理论,引入决策命题集的概念,对决策命题加以约束;其次分析了现有的决策方法,对线性加权组合决策方法提出了改进,并结合应用实例给出了详细可行的算法。更多还原

【Abstract】 Evidence reasoning has good performance in dealing with uncertain in formation and has been used in many fields.As the matter of fact,the effectiv e decision making procedure remains an open problem for D-S theory.In this pap er,based on algebra field extending theory,to restrict the proposition number ,a concept of decision making proposition set is introduced.After analyzing t he existing decision rule,a new improved rule,the linear combining of belief f unction and plausibility function,is proposed.At the end,the algorithm and e xamples are given.更多还原
