【摘要】 已有的建模技术较好地解决了连续系统、离散系统和连续离散混合系统等定量系统的建模问题,但是针对定性定量混合系统的建模问题尚缺乏很好的技术支持。首先介绍了复杂系统建模技术背景;对于复杂系统中的定量模型,基于已有的多学科虚拟样机系统高层建模语言进行建模,并在其基础上进行了改进以支持复杂系统中定性定量集成建模,提出了复杂系统定量定性综合建模方法,以及定量定性集成建模语言。在复杂系统中基于因果关系的定性系统的建模方面,引入了因果图理论,并做了适应性修改,形成了基于因果关系的定性系统的建模文本规范。最后,给出了一个应用示例和结论。更多还原

【Abstract】 The former modeling technology can solve the quantitative systems modeling issues well,which include continuous system,discrete system and continuous-discrete system,but there are not effective technology strategies about the qualitative and quantitative integration system modeling.The complex system modeling technology background was firstly presented.The modeling of quantitative parts of the complex system is based on the System High Level Modeling Language for Multidiscipline Virtual Prototype,which was improved in order to support complex system qualitative and quantitative synthetically modeling.Then the complex system qualitative and quantitative synthetically modeling methods and the modeling language were studied.The cause and effect diagram theory was introduced and modified,and Causality-based Qualitative System Modeling Textual Criterion was given for the causality-based qualitative models of the complex system.Finally,an application demonstration and the conclusion were also provided.更多还原
