摘要
在综合电子信息系统(command,control,communication,computer,intelligence,surveillance and reconnaissance,C4ISR)和航天维修等复杂系统建设前,对系统的体系结构进行仿真和验证是降低系统后期开发成本和风险的有效方法。提出了基于系统体系结构中的活动模型、规则模型、动态模型和数据模型等向统一的Simulink仿真模型的映射方法,并基于模型驱动架构中的模型转换技术实现了前者向后者的自动转换,不仅能够提高仿真模型构造的效率,还能保证仿真模型和体系结构模型的一致性。哈勃太空望远镜维修系统的体系结构仿真验证案例说明了方法不仅能够验证系统体系结构模型之间的逻辑一致性,还能够对系统体系结构的性能进行有效预评估。
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 meth od from activity model, rule model, dynamic model and data model of the system architecture to Simulink simu- lation model is proposed, and the transformation between them is automated based on the model transformation tech- nique 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 meth- od can not only validate the consistence of the architecture, but also pre-evaluate the performance of the system.
