Although Rough sets with the nonliner feature is expected in the research of Design evaluation, it is a significant problem how to analyze a great deal of decision rules extracted from a decision matrix. Thus, the method to analyze and evaluate a lot of decision rules based on Covering Index of Rugh sets from a statistical viewpoint would be proposed in this paper (No. 1). By the method of the proposal, the view of "Column scores" corresponding to the category score used by Multi-variable analysis was defined and introduced. Therefore, there is a useful advantage that consideration of an analysis result can be performed easily. In addition, this "Column scores" condenses the information on decision rules. The validity of this proposal would be verified using the case study of a digital camera in another paper (No. 2).
