Model driven simulation and validation of system architecture

One effective way to reduce the cost and risk of development of complex systems, such as C⁴ISR and space maintenance systems, is the simulation and validation of the system architecture. The mapping method from activity model, rule model, dynamic model and data model of the system architecture to Simulink simulation model is proposed, and the transformation between them is automated based on the model transformation technique of the model driven architecture, which can improve the effectiveness of the construction of the simulation model, and can ensure the consistence between architecture and the simulation model. The case study of the simulation and validation of the architecture of the Hubble space telescope servicing system shows that the proposed method can not only validate the consistence of the architecture, but also pre-evaluate the performance of the system.
