摘　　要：首先,设计CP-nets一致排序生成算法,该方法通过量化用户的每个结果属性的偏好,获取结果属性的偏好优先级,这些值能准确地反映出用户的偏好,从而得出任意结构CP-nets的一致排序。最后通过实验验证,与其他方法相比,该方法获得一致性序列所需的运行时间少,推理速度快,得到结果的效率更高。The key to CP-nets research is to consistently ordering CP-nets to obtain preference relationships among user attributes.First,design the CP-nets consistent ordering generation algorithm.This method obtains the preference priority of the result attribute by quantifying the preference of each result attribute of the user.These values can accurately reflect the preference of the user,so as to obtain an arbitrary structure consistent ordering of CP-nets.Finally,it is verified by experiments that compared with other methods,this method requires less running time to obtain a consistent sequence,faster inference speed,and higher efficiency in obtaining results.
