摘　　要：在组件化建模与仿真领域内,基于BOM规范的KD-XSRFrame组件建模与仿真框架得到了广泛的应用,但是以离散时间仿真为手段的设计模式使得由BOM组件构成的仿真系统性能不高。因此,如何提高运行效率成为基于BOM的组件式建模与仿真必须解决的问题。根据现有组件系统的不足,引入离散事件的概念重新设计了BOM组件模型和仿真引擎,提出了基于离散事件系统规范的BOM组件建模框架,实现了以事件为中心的仿真引擎。测试结果表明该系统能有效地减少模型调用和引擎工作的开销,显著地提升了整个仿真系统的运行性能。In the field of MS of Component, the modeling and simulation framework based-on Basic Object Model （BOM） named KD-XSRFrame has been used widely, but its performance is inefficient for the design basis of discrete time. And the key issue in BOM component MS is how to improve the performance of simulation application. The deficiencies of legacy system was profoundly discussed, the BOM component and its engine were reengineered by using the concept of discrete event, a new modeling framework of BOM base-on Discrete Event System Specification was put forward, and a new engine was designed which focused on events. The experiment shows that the BOM component and engine of discrete event can sharply decrease the spending of model function calling and time advancing, and greatly improves the performance of simulation application system.
