A Study Of Rough Set Theory And Application Of Uncertain Managerial Decision Based On Rough Set Theory

The Rough set theory has been applied in many areas as a powerful tool in processing uncertain knowledge.In this dissertation ,we discuss the fundamental concepts of Rough set theory and the main points in Rough set applications, including the basic view points and characters of Rough set theory ,the universal models of the theory implication, the main algorithm ,the attributes reduction program ,common used software of Rough set theory and the applications of Rough set theory in the partner selection of enterprise annexation . The research and discussions in this dissertation have formed a well-established Rough set application theory and technical proposal .Prepare for the combination of uncertain managerial decision and rough set theory by reviewing the managerial decision methods .Discuss the fundamental viewpoints and characters of Rough set theory ,summarize the research and application status of Rough set theory.Discuss the possibility and necessity of the application of Rough set theory in uncertain managerial decision .Discuss the knowledge reduction method based on Rough set theory.Bring forward the flow chart of Rough set application .Apply the Rough set theory to the importance estimation of index in partner selection during the real case of annexation between Chinese enterprise and foreign enterprise. Greatly improve the efficient of enterprise uncertain managerial decision and get the important conclusion behind the numerous data by laying out the decision-making tables and reduce them through the methods of decision-making tables and attributes reduction ,all of which has proved the efficiency of resolving decision-making problems by rough set theory. Finally, a recapitulative conclusion is given, and the future research directions are proposed.
