摘　　要：作为Vague值概念的拓广,文中引入三参数Vague值,给出三参数Vague值上一个较为一般的贴近度表达式.在此基础上,对相应的Vague值上的贴近度进行研究,给出一个较为一般的Vague值上的贴近度表达式.当文中提出的Vague值上的贴近度的参数取某些特定的值时,可得到已有的一些Vague值上的贴近度表达式.最后,给出所提贴近度在模式识别及医疗诊断中的应用.As an extension of vague values, the concept of three-parameter vague values is introduced in this paper, and a general similarity measure expression between three-parameter vague values is presented. Based on this expression, a corresponding general similarity measure between vague values is researched and a relatively general expression is given. When the parameters of the proposed similarity measure between vague values are selected as some special values, some existent similarity measure formulas between vague values can be obtained. The applications of proposed similarity measure in pattern recognition and medical diagnosis are shown.
