摘要： DEVS是一种层次的模块化的系统说明方法,它提供了一种层次的模块化的系统说明方法。文中给出的UML-BD方法就是在UML中结合DEVS这一特点,对UML进行一定的扩展;同时还在UML中增加了时间的约束,满足系统的实时性的要求。该方法适合一类层次结构清晰、实时性强的系统的建模,如C4I系统。

Abstract: DEVS is a formal description of discrete event system and it provides a hierarchical and modular system specification. In this paper, the UML-BD method is the extension of UML through integrating the DEVS feature, at the same time adds the time restriction in order to satisfy the need of real-time system. This method adapts to model the distinct hierarchy and high real-time system, such as C4I system.
