An Improved MCGC and Its Application in Credit Evaluation of High-Tech Enterprises

An improved evaluation method of membership cloud gravity center(MCGC) is proposed and applied in credit evaluation of high-tech enterprises.Using the basic idea of TOPSIS method for reference,the comprehensive membership cloud gravity center vector is normalized based on ideal state and negative ideal state.Through the modified weighted deviation degree,the change of membership cloud gravity center is measured scientifically. Thus,the draw back of traditional MCGC is overcome.And then,in view of uncertainty usually existing in credit evaluation of high-tech enterprises,an empirical credit evaluation for high-tech enterprises is carried out by the improved MCGC.The empirical analysis results show that the improved MCGC is reasonable and suitable.
