Abstract: The σ-measures and weak σ-measures are important concepts in fuzzy information measure.Entropy,distance measure and similarity measure are special cases of σ-measures and weak σ-measures.Based on the definition of intuitionistic interval-valued fuzzy sets,this paper gives the definitions and properties of σ-entropy and weak σ-entropy,σ-distance measure and weak σ-distance measure,σ-similarity measure and weak σ-similarity measure,then discusses basic relations among them.

Key words: intuitionistic interval-valued fuzzy sets, σ-measures, weak σ-measures, entropy, distance measure, similarity measure

摘要: σ-度量和弱σ-度量是模糊信息度量的重要概念。熵、距离测度和相似测度是σ-度量和弱σ-度量的特例。在直觉区间值模糊集定义的基础上,给出了σ-熵和弱σ-熵、σ-距离测度和弱σ-距离测度、σ-相似测度和弱σ-相似测度的定义与性质,并讨论了它们之间的关系。
