Qualitative modeling of complex system based on cloud model using QSIM
基于云模型以约束为中心的复杂系统定性建模

The absence of effective depictive expression of uncertain information causes the insufficient usageof uncertain information. The qualitative modeling method of complex system based on QSIM and studied cloud model according to the theory and method of cloud model. Firstly this paper gave the expression of uncertain information based on cloud model. It created the value space of variable by the cloud model and group experts. Then constructed construction of system qualitative constrain function based on cloud model. Lastly applied the modeling method to the case of modeling in the agile supply chain management. The proposed method has the merit of objective expression the uncertain information, and the fusion of qualitative and quantitative information can be used in complex system simulation.
