摘要
对普通选择函数所导出的偏好关系R*,R,R,■及其之间的联系进行了讨论,并以此为基础,深入研究了模糊情况下对应的偏好关系及其之间的联系,给出了它们相等的一些充要条件。
In this paper, we investigate the revealed preference relations R ＊, R,R^-, R~, revealed by crisp choice functions and the links between them. Based on the conclusions for crisp choice functions, we carry out a further research on the fuzzy preference relations corresponding to the crisp ones and the relationships between them. In the end, we obtain some necessary and sufficient conditions under which some of these preference relations are equal.
