SysML中的模块定义图,英文为 “Block Definition Diagram”,简称BDD,是系统建模过程中最为常见的图之一,BDD是一种结构图,它主要对系统的结构组成以及组成元素间的关系进行描述。SysML中的图类似于UML中的类图,在学习的过程中可以以类比的方式进行学习。 二、模块定义图介绍 如下图所示,BDD中可以包含 包、模型、模...

最常见的一种SysML图就是模块定义图(Block Definition Diagram,BDD)。可以在BDD中显示不同类型的模型元素和关系,以说明系统结构的信息。 1、目的 在BDD中显示的模型元素——模块、执行者、值类型、约束模块、流说明、接口——都是其他模型元素的类型,它们会出现在其他8种SysML图中。把出现在BDD中的元素叫做定义元...
