Abstract: This paper presents a new connection numbers of Vague sets similarity measure method, using set pair analysis in the connection numbers theory and Vague sets theory. The method depicts the similarity measures of Vague sets IDC state relations by connection numbers theory certain and uncertain law, overcomes the defects and shortcomings of the traditional method of similarity measure, and points out connection numbers is the general form set for Vague sets. Example shows that the method is feasible, is an effective method of Vague similarity measure.

Key words: Vague sets, similarity measure, connection numbers method

摘要： 运用集对分析法中联系数理论与Vague集理论，给出了一种新的Vague集相似度量的联系数方法。该方法用联系数理论确定与不确定规律，刻画了Vague集相似度量的同异反状态关系，克服了传统相似度量方法的缺陷与不足，并指出联系数是Vague集的一般形式及表示。通过实例表明该方法切实可行，是一种有效的Vague相似度量方法。
