摘要
根据实际中的三种信息传递情况,本文利用粗糙模糊集、模糊子集、截集等理论讨论了λ-模糊粗传递模型的特性,得到了λ-模糊粗传递模型与模糊粗传递模型的关系,给出了两种分解定理。以此为基础,分析了λ-模糊粗传递模型中信息的变化情况,给出了信息精确传递的条件,进一步得出了提高信息传递精确性的方法。λ-模糊粗传递是粗糙模糊集的一种新的应用。
According to three practical situations of information communication,this paper discusses the properties of λ-fuzzy rough communication model using rough fuzzy sets,fuzzy set and cut set.It obtains the relations between λ-fuzzy rough communication model and fuzzy rough communication model,and presents two decomposition theorems.Basing on these,this paper analyzes the change of information in λ-fuzzy rough communication model,and gives the conditions that information is communicated accurately.It further gives a method of improving the accuracy of fuzzy information rough communication.λ-fuzzy rough communication is a new application of rough fuzzy sets.
