提出了一种新主观逻辑.原主观逻辑是进行不确定性推理的一个理论框架,它建立在D-S证据理论的框架之上,是标准逻辑和概率演算的扩展,由于其在信任管理中的成功应用而被广泛关注.但是它要求鉴别框架元素必须是互斥的.提出的新主观逻辑是在Dezert-Smarandache理论的框架上对原主观逻辑的一个扩展,解决了这个强约束,能够同时处理不确定和矛盾的信息.另外,推导了3个逻辑算子,并且证明是原主观逻辑的逻辑算子的扩展.定义了两个证据算子,并指出原主观逻辑的合意算子的缺点.最后,通过实验说明其计算复杂度是可以接受的. 相似文献

To solve multiple attribute decision-making problems with attribute values or decision values characterized by trapezoidal intuitionistic fuzzy numbers (TIFNs), we define a trapezoidal intuitionistic fuzzy induced ordered weighted arithmetic averaging (TIFIOWA) operator, which is an extension of the induced ordered weighted arithmetic averaging operator. We derive and prove some related properties and conclusions of the TIFIOWA operator. To compare the TIFNs, we define possibility degrees of the TIFNs. Based on the possibility degrees of the TIFNs and the TIFIOWA operator, we construct a new method to determine the order of alternatives in multiple attribute decision making and to choose the best alternative. Finally, a numerical example shows that the developed method is feasible and effective. 相似文献
