Grey Cloud Model and Its Application in Intelligent Decision Support System Supporting Complex Decision

Abstract

In order to improve the support ability of dealing with the complex decision problem, grey cloud model and intelligent decision support system (IDSS) based on grey cloud model is proposed. A new uncertain model, grey cloud model is proposed. Firstly the definition depiction of grey model is given. Then representation uncertain of knowledge based on grey cloud model in knowledge database is proposed. The data mining method based on is proposed. Lastly the case of data mining based on grey cloud model in intelligent decision support system is given to verify the validity of grey cloud model. The innovation of method is that the grey cloud model and intelligent decision support system based on grey cloud objectively express the character of complex problem. This increases the support ability of dealing with the complex decision problem in IDSS.
