摘要
在建模和仿真领域,很多模型因为与仿真系统结合过于紧密,导致模型难以重用。本体驱动建模理论是一种为模型重用而生的仿真建模方法论,基于该理论提出了一种新的DEVS(Discrete Event System Specification)建模方法。该方法建立了DEVS建模本体DEVSMO(DEVS Modeling Ontology),将具体的DEVS模型描述为DEVSMO的实例,这种形式的DEVS模型脱离的具体的仿真环境,在一定程度上提高了模型的复用性。利用DEVS规范和具体仿真环境下的可执行模型的对应关系,开发了DEVSMO实例映射工具DEVSMO_Mapper,将这种DEVSMO实例映射为DEVS可执行模型,验证了该方法的有效性。
In the field of modeling and simulation, it's difficult to reuse the models because the models and simulation system are coupled seriously. The Ontology-driven modeling theory is a simulation modeling methodology for model reuse. A new DEVS modeling method was proposed based on this theory. The DEVS modeling ontology DEVSMO was built and the DEVS model could be described as the instance of the DEVSMO. This form of DEVS model was independent of the DEVS simulation environment, which improved the model reusability. A tool was developed to translate the DEVSMO instance to DEVS executable models to verify the effectiveness of the method.
