UseCases define the offered Behaviors of the subject without reference to its internal structure. These Behaviors, involving interactions between the Actors and the subject, may result in changes to the state of the subject and communications with its... Source Unified Modeling Language 2.5.1
This diagram expresses only the nominal states. Exception states, like “acceleratorFailure,” are not expressed on this diagram. Source OMG Systems Modeling Language (SysML) 1.6
Also note that this state machine refines the requirement “PowerSourceManagment,” which will be elaborated in the requirements sub clause of this sample problem. Source OMG Systems Modeling Language (SysML) 1.6
Note that this state machine was developed in conjunction with the DriveBlackBox interaction in Figure D.7. Source OMG Systems Modeling Language (SysML) 1.6
Figure D.8 depicts the operational states of the HSUV block, via a State Machine named “HSUVOperationalStates.” Source OMG Systems Modeling Language (SysML) 1.6
The conditions for each alternative in the alt controlSpeed sub clause are expressed in OCL, and relate to the states of the HybridSUV block, as shown in Figure D.8. Source OMG Systems Modeling Language (SysML) 1.6
“BlackBox” for the purpose of this example, refers to how the subject system (HybridSUV block) interacts only with outside elements, without revealing any interior detail. Source OMG Systems Modeling Language (SysML) 1.6
