If you still prefer to model this in a sequence diagram, here’s the notation to use. Both loop and conditional use interaction frames, which are ways of marking off a piece of a sequence diagram. The sequence diagram example below shows a simple algorithm based on the following pseudocode:...
What is a SysML Sequence diagram? Definitions Message: AMessage(notation: arrow) represents communication from one object to another, with the expectation that a useful behavior will ensue. Messages may besynchronous(notation: open arrowhead) orasynchronous(notation: black-triangle arrowhead). ...
Sequence Diagram,用于描述对象间的消息交互序列。 状态机图 State Machine Diagram,通过状态以及状态之间的转移对离散行为建模,它把行为表示为对象的状态历史。在状态的转移、进入和退出过程中会调用活动,并指定相关的事件和守卫条件。 用例图 Use Case Diagram,描述外部参与者对系统的使用,这是通过系统向参与者提供一...
SysML 序列图(Sequence Diagram) SysML序列图是另一种可以用来说明系统动态行为信息的图。你可以使用叫做生命线的元素,为系统行为中的参与者建模,然后使用生命线之间的消息,为那些参与者之间的交互建模。你可以指定交互的时间约束和持续期间约束。还可以使用各种交互操作符来指引交互的执行。使用交互可以对一系列交互之间...
SysML was designed to allow further language extensions. Seidewitz expects various disciplines to specify new extensions that are more powerful than current UML profiling mechanisms. Examples include the Software Engineering Institute'sworkto extend SAE Architecture Analysis and Design Language and OMG's...
the method could transform sequence diagrams into colored Petri nets,and made its simulation and analysis.Besides of this,it could verify the characters of the model,such as absence-deadlocks,boundness,liveness,etc.Finally,the examples of digital certificates updated analysed the semantic of the ...
