英文摘要：

ABSTRACT：As the absence of effective depictive expression of uncertain information which causes the insufficient usage of uncertain information, the representation of uncertain information and qualitative modeling method based on cloud model was proposed with digital simulation. Firstly, the variable space expression of uncertain information based on cloud model was given. Then, the method fused with qualitative information of improved quantitative simu- lation was studied based on cloud model. The principle of improved quantity simulation and process was given in this article including the key problems about the fusion calculation of qualitative and quantitative information, the lasting and cycle variation of qualitative information and so on. Lastly, the modeling method was applied to the case of mod- eling in the complex supply chain management system simulation to verify the feasible of method. The results verify that method proposed in this paper has the merit of objective expression of the uncertain information. And the fusion of qualitative and quantitative information can be used in complex system simulation.
