SysML及其在C4ISR系统建模中的应用研究

针对C4ISR分析与设计中建模手段的不足,提出了基于SysML对C4ISR系统的组成、接口与通信、功能、状态变迁、系统事件跟踪等进行建模的方法.在分析SysML四层元模型体系结构基础上,分析了SysML的语义与图形表示机制,探讨了SysML对C4ISR系统建模的支持作用,并以某防空指挥系统的建模为例,对系统的组成、接口与通信关系、系统功能、状态转移以及事件跟踪进行了描述,系统分析了基于SysML的C4ISR系统建模过程.对于提高C4ISR系统建模能力提供了一种可行的思路.

SysML and Its Application in Modeling C4ISR System

Aiming at the deficiency of modeling method in C^4ISR analysis and design, this paper brings forward a method based on SysML to model the composing, interface, communication, function, state transition, system event tracing of the C^4ISR system. By analyzing the four - layer meta - model architecture of SysML, the paper analyzes the semantic and graphic representation mechanism, discusses the supporting effect of SysML in modeling C^4ISR system. Lastly, the paper uses the modeling of some anti - air command system as an example, describes the composing, interface, communication, function, state transition, system event tracing of the system, and analyzes the modeling process of C^4ISR system based on SysML. This method provides a feasible solution to improve the modeling capability of C^4ISR system.
