SysML Simulation (Activities & State Machines)

Session 16: Introduction to SysML Simulation

• Why simulate SysML models?
  
  

• Benefits of execution: validating logic before implementation
  
  

• Supported diagrams for simulation (Activity, State Machine, Sequence)
  
  

• How tools like Cameo, Rhapsody, and Papyrus enable simulation
  
  

Demo: Facilitator runs a simple Activity Diagram simulation in a tool

Session 17: Activity Diagram Simulation

• Mapping actions to simulation steps
  
  

• Token flow semantics in activity diagrams
  
  

• Using decision nodes, forks/joins, and object flows in simulation
  
  

• Monitoring execution path and validating scenarios
  
  

Hands-On Exercise:

• Simulate the example system
  
  

• Observe different paths
  
  

Session 18: State Machine Simulation

• Understanding state machine execution semantics
  
  

• Events, triggers, guards, and transitions during simulation
  
  

• Entry/exit/do actions
  
  

• Visualizing state transitions in simulation view
  
  

Hands-On Exercise:

• Simulate a Coffee Machine State Machine
  
  

• Trigger events and observe state changes
  
  

Session 19: Scenario-Based Simulation (Integration)

• Linking requirements to simulated behaviors
  
  

• Using simulation for “what-if” analysis
  
  

• Combining activity and state machine simulations
  
  

• Comparing alternative flows
  
  

Hands-On Group Exercise:

• Each team simulates both Activity & State Machine diagrams for their mini-project
  
  

• Capture outputs and validate against requirements
