【Abstract】 Decision analysis of information system can be implemented by using concept of approximations in Rough Sets Theory,Genetic Algorithms provide a general frame to optimize problem solution of complex system without depending on the domain of problem,it is effective and robust to many kinds of problem.The paper combine Genetic Algorithms and Rough Sets Theory to complete decision rule analysis by an example of information table,the combination enable us to process decision rule analysis of information system effectively,it is also useful for computer auto -computing and information processing.更多还原
