Aiming at the characteristics of complex system simulations,such as a lack of information,and the possibility of QSIM modeling method employing differential equations,a qualitative modeling method combining QSIM and GM( 1,N) is proposed. First the realtive researches are reviewed. The variable space expression of uncertain information based on the cloud model is provided. Then the process and principles of combination of QSIM and GM( 1,N) qualitative simulation are given. Lastly,the modeling method was applied to the case of modeling in the modeling and simulation of the complex system to verify the feasibility of the method. The results show that this method has full use of fewer system information. Both quantitative and qualitative information can effectively be integrated into modeling and simulation of complex systems.
