Example: CONOPS
• MBSE Animator developed by SERCO – Visualize operational scenario CONOPS to play out
mission threads
– Evaluate effects of system characteristics
• Inputs – System architecture definition
from COTS tool (i.e. IBM Rational)
– System specific parameters (vehicle routes, sensor information, etc.)
• Results – Dynamic, system-driven, event-based,
physics verified, 3D visualization
– Verification of CONOPS and early system designs
