| Abstract: | A probabilistic information system was used to express the uncertainty relationship between objects and attributes.Based on rough sets and average operator,extended decision rules of the probabilistic information system were obtained.Decision inference of the extended decision rules was implemented using fuzzy CRI(compositional rule of inference). |
