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.
