Second Discuss on the Similarity Measure Formulations between Vague Sets
再论Vague集间的相似度量公式

A great quantity of similarity measure formulations between vague sets is enumerated. The analyzing of these formulations show that most of the formulations have some kind of shortcomings. Using the method of the piecewise functions to try repairing all these formulations could make most part of the formulations effective. This effort has proved useful for the development of Vague sets.
