【摘要】 针对群体复杂决策中知识的不确定性的表示问题,给出了基于云理论的知识表示和处理方法,首先给出了基于云模型的语言变量表示和命题的描述,然后阐述了不确定知识的产生式表示,最后给出了基于相对贴近度和最大隶属度的两种知识推理方法,基于云模型的知识表示和推理方法能够充分的表达出不确定知识的模糊性和随机性,具有较大的客观性.更多还原

【Abstract】 In order to express the uncertainty of knowledge in group complex decision making, the presentation and reasoning of knowledge based on cloud theory is proposed. At first the expression of language variable and description of proposition based on cloud model is studied. Then production presentation of uncertain knowledge is given. At last two knowledge reasoning method based on relative distance and maximum degree of subjection is expounded. The blurring and ransomicity of uncertain knowledge in the presentation and reasoning method based on cloud theory is fully expressed. So the method has more objectivity.更多还原
