摘要：

复杂系统日益呈现出不确定性、非线性等定性特征,已有的建模方法不足以构建具有定性特征的复杂系统。基于此,提出一种复杂系统定性模型描述方法(QMDM)。QMDM结合定性仿真理论,在UML基础上对其组件图、时序图以及状态图进行扩展,可视化地表达出定性模型的建模过程。组件图用于静态的表达出定性模型包含的定性约束关系。时序图和状态图用于动态的表达出定性模型的时序性,以及状态迁移。此外,给出QMDM的形式化定义,便于以后模型验证,并将研究成果在空调制冷系统中进行了初步应用。

Abstract:

Hardly can the existing modeling methods meet the demands of constructing the complex system with qualitative attribute that presents a trend towards uncertainty and nonlinearity.Thus,a description method of complex system qualitative model (QMDM) is put forward.Based on the combination between the qualitative simulation theory and the extension of UML component diagram,sequence diagram and state diagram,QMDM visually expresses the modeling process of qualitative model.The component diagram gives a static expression of qualitative constraint relations including in the qualitative model,while the sequence diagram and state diagram dynamically convey the time sequence as well as state transition embedded in the qualitative model.In addition,the formal definition of QMDM is given to provide convenience for later validation.Finally,the research achievements find a preliminary application in the air conditioning refrigerating system.
