摘要
粗糙集理论和D-S证据理论都是重要的不确定性推理方法,两者各有优缺点。现实生活中,不完备信息系统广泛存在。研究了将两种理论结合用于不完备信息系统以进行规则提取,并用实例进行了验证。
Both of rough set theory and D-S evidence theory are important uncertainty reasoning methods, and each one has its own advantages and disadvantages. Incomplete information system is widely existed in true life. To study rule extracting in in- complete information system on the basis of two theories. Practical application shows that the result is satisfactory.
