2. Outline Model Management and the MBSE Vision Introduction
Challenges in Model Management
Questions…hold for the end of the session

3. 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.

4. A Vision: Managing Information and Knowledge – The Technology
Current Practice
Someday Soon
Duplicated files, document-centric, pictures, static diagrams, mostly non-indexed and unsearchable, stove-piped applications (file to presentation).
Memory-based, 3D, live, searchable, non-duplicative, layered.
The fundamental building blocks exist.
It’s a re-purpose, integration exercise.

5. A Vision: Managing Information and Knowledge – The People
Current Practice
Someday Soon
Write Victorian novels in a naturally ambiguous language.
Use technology to do things the same old way.
Outdated skills and thinking.
A precise and concise language.
Fresh leadership and thinking.
A critical mass with a fresh view.
Building on the core concepts used in modeling the regional highway enterprise (Activity, Resources, Performance, Location, etc.) and domain specific models for communications, dynamic network models, resource / performer models and socio economic models….the combination of all of these modeled factors can help determine how to control the features of the highway to get the transit time delays reduced from say 15 minutes to 5 minutes, perhaps simply by eliminating the tolling price all together for a short period of time.

6. Introduction to MBSE Model Management
It is so much more than just the configuration management of models.
With current technology:
Which repositories contain what
Access to and settings for repository applications
The effect of repositories on model content (model scope, packages and relations)
Dealing with generations of data (baselines, product lines, engineering changes, defects)
Exchanging data among models and applications
Sequencing the execution of models
Generating and controlling documents and reports
Generating and controlling code generation and source code
Application settings across projects and teams
Developing, sharing and using utilities
Application and model simulation logs
Generating, reporting and controlling metrics
Controlling and communicating workflows, methods, tools, practices, guidelines
Versions of standards applicable to a project baseline
Mechanisms for collaboration
Its time to get real to realize the vision
Provide some basic definitions and examples related to the SoS / Enterprise modeling context.
