Abstract: A novel rough set model,called double quantitative rough fuzzy set model,was established based on the “logical and operator” and “logical disjunct operator” in ordered information system.It overcomes fuzzy problems which cannot be solved by using traditional “logical and operator” and “logical disjunct operatror” rough model.Some important properties were presented,and significance of the model was shown by the supermarket case study.
