2. Integrated Systems Engineering Vision
Automatic Cruise Control <FAULT>
Thermal/Heat Dissipation: 780°
Ergonomic/Pedal Feedback: 34 ERGS
Hydraulic Pressure: 350 PSI
Sensor MTBF: 3000 hrs
Power Rating: 18 Amps
Hydraulic Fluid: SAE 1340 not-compliant
Integrated Systems Engineering Vision
If we can pull this off we can achieve this ultimate vision for integrated requirements…, visualizing where requirements go and how they interact with various systems… For example, …starting with the car, what are the requirements associated with the front end of this vehicle.
Shows current requirements by graphically clicking on the car…
What about changing a requirement…stopping distance
Show the potential impact of changing stopping distance including…
Thermal/heat problems with brakes
Ergonmic feedback problems with brake pedal
Hydraulic fluid rating violation
Failure modes/MTBF rating problems with sensors
Hydraulic pressure problems
Electrical fault problems
Zooming into the electrical box, highlights a fuse
Clicking into the fuse brings up the schematic and highlights a fuse link
Clicking into the schematic zooms in on the wire harness that has the problem—including the signal for a failed sensor that in this particular failure mode causes the short.
…which allows us to go look at the Failure Modes document and update appropriately.
Updating the software to handle that fault
…and even seeing the impact on our safety rating and insurance costs.
Minimum Turn Radius: 24 ft.

Presentation for the INCOSE Symposium 2011 Denver, CO, USA

4. Questions to be Addressed
1) What should other engineering disciplines expect from MBSE, and what should systems engineering expect from other disciplines to enable MBSE?
2) What can MBSE learn from model-based approaches used in other engineering disciplines? 
3) How should the practices and tools be integrated/coupled across disciplines? 
4) How are the system, hardware, and software models managed to ensure an integrated technical baseline?
5) How should a program be organized to achieve more effective utilization and application of model-based engineering?
