Abstract: In vague sets the applications of the similarity measure formulas between vague sets are most broad.But we regret that the great majority of the formulas have the faults .In this paper with a method of the piecewise functions we try to mend these formulas,such that the vast majority of the formulas will can continuously use.And a new similarity measure formula between vague sets was presented. This formula more possess the rationality.

摘要： 在Vague集中，Vague集间相似度量的应用是最广泛的，但遗憾的是这些公式中的大多数是有缺陷的。本文中，我们用分段函数的方法试图修补这些公式，使得这些公式中的大多数能够继续使用。本文还给出一个新的Vague集间的加权相似度量公式，该公式更具合理性。
