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. Dry Pavement Braking Distance at 60 MPH : 110 ft. 90 ft Minimum Turn Radius: 24 ft. Dry Pavement Braking Distance at 60 MPH : 110 ft. 2

MBSE Panel What are the implications and issues for integrating MBSE Into a Multi-Disciplinary Engineering Environment? Panel Representation Systems Software Electrical Mechanical Integration & Test Presentation for the INCOSE Symposium 2011 Denver, CO, USA

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?
