The applications of rough set in integration system evaluation and the setting up of evaluation index system are discussed. The evaluation process is similar to the decision process. Rough set has a lot of advantages in the decision process and is used for the evaluation of the system. The general way of integration system evaluation using rough set is presented. Rough set can also be used in the attribute reduction. The classifying ability of the remaining attributes is not declined when some redundant attributes are moved from the decision table. It can be applied to the setting up of the evaluation index system. This paper investigates the method for establishing the evaluation index system using rough set and its advantages. Two UCI databases are used to validate the method. Experimental results reveal the efficiency of the method.
