ABSTRACT：Rough set theory is an effective approach to processing imprecise and uncertain data, but the decision rules obtained through rough sets method are uncertain for the inpleteness of the information system and the randomness of the data. A reliability evaluation method for decision rules is presented in this paper which is independent of any specific means of inducing rules, and the parameters can be adjusted to suit different information systems.
KEYWORDS：Rough set, information system, decision rule, reliability evaluation, pleteness
