A method of SysML-based visual transformation of system design-simulation models

Aiming at the problem of weak simulation capability of the system design models described formally in model-based system engineering, by applying the meta-model transformation method, this paper presents a visual method of transforming system design models to executable simulation model based on SysML. According to the characteristics of model transformation, two transformation meta-models, transformation rules and transformation activities, are defined abstractly based on SysML and its extension mechanism. The mapping relationships between design meta-model and simulation meta-model are established firstly, and then the visual transformation of the system design-simulation models is achieved by instantiating the transformation meta-model to reduce the complexity of the model transformation. Finally, a case of simple mechanical system is used to verify the feasibility of the proposed method.
