摘要
模糊信息处理是信息科学领域的一个热点和难点。针对一类带有三角模型的模糊信息系统,提出一种基于粗糙集的有序规则获取方法。证明了三角模糊数之间基于可能度的序关系是一种弱序关系,进而将模糊信息系统转化为二元信息系统,利用粗糙集理论推理出模糊信息系统的最优有序规则。仿真实例表明了该方法的有效性。
Fuzzy information processing is a hot and hard topic in the area of information science. A novel rough set-based approach to ordering rule acquisition in fuzzy information systems with triangular fuzzy numbers is presented. it is prowved that the order relation between triangular fuzzy numbers based on possibility is a weak order relation, then the fuzzy information systems are fransformed into binary information systems. Finally, optimal ordering rules are induced using rough set theory. Simulation results show that the method is effective.
