摘要
针对实际中两种信息传递情况,提出了两种信息粗传递概念—下近似和上近似信息粗传递。利用粗糙集理论对这两种信息粗传递进行了讨论,分析了粗传递信息保持不变、发生损失和发生增益的条件,得到了下近似和上近似粗传递信息不变定理,下近似粗传递信息损失定理,上近似粗传递信息增益定理,下近似和上近似信息粗传递原理以及提高信息粗传递精确性的方法。信息粗传递是粗糙集理论的一个新的应用。
According to the two practical situations of information communication, this paper proposes the concepts of lower and upper approximation information rough communication using rough sets. It analyzes the conditions that cause information to remain invariable or cause information to be lost or gained, and obtains rough communication information invariability theorems, an information loss theorem, an information gain theorem, information rough communication principles and the methods of improving accuracy of information rough communication. The rough communication is a new application of rough sets theory.
