Modeling the use case diagram related to system behavior
Modeling the use case diagram illustrating global system behavior
The figure on the right provides an abstract overview of system behavior through a SysML use case diagram. The use case illustrates the system behavior that is visible to the end user and external to the system. In the figure, there are several use cases present, related to how the system is operated, controlled, supervised etc. Here, plant refers to the experimental industrial automation unit.
