| Abstract: | For fuzziness of enterprise decision activities,a method combined with variable precision rough-fuzzy sets and GRAI Methodology is proposed to realize rules acquisition.GRAI Models are used to model the enterprise decision activities with GIM.Variable precision rough-fuzzy sets make dimensionality reduction based on the subjective decision information and realize rules acquisition.This method improves the objectivity and effectiveness of decision activities.Finally,an example is used to verify this method.Numerical results show the feasibility and effectiveness of this method. |
