摘要:

阐述了复合大系统(system of systems, SoS)的特点及基于仿真的性能分析需求,介绍了传统的自底向上和自顶向下两种基本系统仿真方法,并分析了各自的优缺点。在对状态图、随机状态图和代理模型等基本概念介绍的基础上,提出了一种新的适应于SoS性能分析的仿真方法,并通过一个弹道导弹预警信息系统仿真案例对新方法的可行性进行了验证。

Abstract:

The characteristics of system of systems(SoS) and its needs of performance analysis based on simulation are described. Two traditional bottom-up and top-down simulation methods are introduced, and their advantages and disadvantages are discussed. On the basis of introducing the basic concept of statecharts, stochastic statecharts and surrogate model, a new simulation method adapting to SoS performance analysis is proposed, and a simulation case of the ballistic missile early warning information system is presented to test the feasibility of this new method.
