针对复杂系统仿真中系统信息缺乏、QSIM建模方法可使用微分方程的特点,在复杂系统仿真方法中,提出了一种GM(1,N)和QSIM相结合的定性建模方法.首先给出了相关研究的现状,然后提出了GM(1,N)和QSIM相结合的仿真建模方法的基本原理和主要过程.最后通过一个系统仿真建模实例验证了该方法的可行性.结果表明,该方法具有充分利用系统较少信息,能将定量和定性信息有效地融合与复杂系统的仿真建模之中的特点.

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.
