事件图模型及其在分布交互式仿真中的扩展

Event Graphs Model and Its Extension for Distributed Interactive Simulation

随着离散事件仿真的不断发展,涌现出许多建模方法,事件图模型就是其中之一。事件图模型具备简单、通用、快速和可扩展等优点,因此首先对事件图基本结构、要素和图形进行介绍,然后针对复杂仿真的需求,在基本事件图基础上,借鉴面向对象的思想进行的扩展,增加封装、接听模式和桥对象等概念;最后为适用于分布交互式仿真,提出在事件图中增加镜像事件的概念。事件图是图形化的建模方法,为能对其进行清晰和无二义的描述,还采用了集合论的方法对事件图和扩展事件图分别进行刻画。

With the development of discrete event simulation, many modeling approaches come forth. Event Graphs （EG） is one of them. It is simple, common, faster for building models and has better extendibility. So firstly, the basic structure, elements and graphs are introduced. Then, EG is extended based on object - oriented theory to meet the requirements of complex simulation. It has additions： encapsulation, listener pattern, bridge object and so on. Lastly, EG is extended again for being used in distributed interactive simulation with mirror event. EG is a graphical modeling technique. So EG and extended EG have been described by set theory for clear and nonambiguous representation.
