Present Situation and Development Tendency of Grey System Theory in Fault Forecast Application

Grey system theory has been spread rapidly and applied in all kinds of scientific field since it was put forward.It can deal with data and information,analyse the phenomena,build up its models and forecast the future development situation of the system under the background of the uncertainty in less data.At first,the application of GST(grey system theory)in the field of fault forecast was introduced.Then the theory base and the modelling method of grey forecast model were described by use of a typical application example.Based on this,the present application situation of grey forecast theory and its advantage and insufficiency were analysed.Finally,the future development tendency of its application in the field of weapon equipment system fault forecast was discussed.
