Dynamic Upper Approximation Fuzzy Information Rough Communication Model

Ji-qin LIU, Hai-yue ZHANG


According to practical situations that any potentially useful information cannot be lost and the communicated concept is a dynamic fuzzy set, using the two-direction S-rough fuzzy set with dynamic characteristics, a dynamic fuzzy rough communication model is constructed. The concept of dynamic fuzzy information communication quantity is defined by using the cardinality of a fuzzy set, and the condition of information fidelity in the process of information communication is obtained. Dynamic fuzzy rough communication is a new application of two-direction S-rough fuzzy set theory.
