摘要
给出了反对称指标的新定义,并将其与王等文中的相关定义作了比较.接着在彭等提出的条件下,讨论了T-传递、S-负传递、T-S-半传递、T-S-Ferrers性质、反对称以及非自反等模糊关系性质指标之间的关系,从而将Fodor关于非自反、T-传递、T-S-半传递以及T-S-Ferrers性质之间关系的结论和王关于非对称、S-负传递、T-传递、T-S-半传递以及T-S-Ferrers性质之间关系的结论推广为程度描述.
Asymmetry indicator of fuzzy relations was redefined and compared to the definition proposed by Wang et al.Then the relation among some property indicators of fuzzy relationships,including Ttransitivity,negative S-transitivity,T-S-semitransitivity,T-S-Ferrers property,asymmetry and irreflexivity indicators were investigated under the conditions proposed by Peng ea al.Some results on irreflexivity,T-transitivity,T-S-semitransitivity and T-S-Ferrers property done by Fodor and ones on asymmetry,negative S-transitivity T-transitivity,T-S-semitransitivity and T-S-Ferrers property done by Wang were extended to the degree description.
