Journey to a Model-based Approach

"We make the magic."
That's our motto at Walt Disney
Imagineering, and it's a belief that
permeates everything we do.

OPPORTUNITIES
• Deliver more innovative guest experiences with lower technical risk
• Lower Development Costs
• Optimize Performance/Cost

OPPORTUNITIES
Deliver more innovative guest experiences with lower technical risk
• The earlier that a Model-based approach is used the lower the risk
• Don’t want to be the Physics Police
• Want to be the enablers of the Creative Vision

OPPORTUNITIES
Lower Development Costs
 Become less dependent on physical prototyping
 Shorten the amount of time and people dedicated to field development
Optimize Performance/Cost

REAL-WORLD ENGINEERING AND CULTURAL
CHALLENGES
• Teams
• Requirements & Creative Process
• Document-driven process
• Phase-gate process

Concurrent ≠ Collaborative

REQUIREMENTS
 Not great about creating requirements
 But, know what we want when we see it

Never thought I would be part of projects where there are serious discussions about
a “Barrel of Monkeys” and how to work gags into the show!

• Presenting to wider groups

VISION
Vision for starting in the earliest "Blue Sky" phase to define the Creative Intent all the
way through the final Commissioning

BLUE SKY
Capture the experience that the Creative team is looking for
 Paths
 Accelerations
 Environment (wind, temperature, water)
 Visuals
Create dynamic simulations with realistic visualizations (not just animations) to
present back
 Do not concentrate on how to do this
 Just can it be done?
Develop a simulator (both a model and a real one) to discover what the experiences
described may actually feel like
Then develop the architectures (physical and controls) that can realize the creative
intent (develop as many alternatives as possible)

FULL LIFE-CYCLE SUPPORT
Model-Based approach along with an Incremental (Spiral) Development Process
allows for more reviews without spending too much time preparing for phase
reviews
• Test Plan = Simulation Plan
• Deploy Code
• Simulators
• Hardware-in-the-Loop

POLL
Do you think it would be easier or harder to implement a Model-
based approach in a creative industry where technical
requirements may be less rigorously defined?
A. Easier
B. Harder
C. MBSE is always hard
