摘要
本文研究和探讨了社会选择中的模糊偏好，在一组模糊理性条件下证明了一个不可能性定理，并将其中的独裁者区分为一般、α－和完全三种，分析了这些独裁者与偏好传递性间的关系，在一特殊传递性下还找到了一个存在α－独裁者或完全独裁者的模糊集结规则．最后。
Fuzzy preferences in social choice are investigated and probed into. An imposibility theory is proved under a serves of fuzzy rational conditions. Furtherly, dictator are divided into general, α and complete dictators. The relations between these dictators and a preference transitive condition are analyzed. Under a special transitive condition, a fuzzy aggregation rule is also found in which these exists a α dictator or a complete dictator. Finally, an example is given.
