Model Based Manufacturing Challenge
• Desire early Manufacturing involvement during system design
• Requiring systems engineers to “speak manufacturing” is a challenge
• How can Manufacturing engage during the systems design phase without “getting in the way?”

Today’s Manufacturing Analysis Workflow
• Two problem classes • Analytical (mathematical relationship, or rule, can be verified) • Visual (difficult to write a rule, but easy to see)
• Start at detailed design • ECAD (Electrical Computer Aided Design) • MCAD (Mechanical Computer Aided Design) • Rule checkers (geometric features) • Reports
– Auto-placed components – Preferred parts – Cost rollup
• Manufacturing Readiness Assessment (MRA) • Virtual Prototype Models (visual) • Manufacturing process modeling (discrete event
simulation) • Automate where possible

Today’s Focus
Start Here In the Future
• Evolve from focus on “in series” analysis of detailed design to include . . .
• . . . “in parallel” input during architecture trade studies . . .
• . . . Driving need to speak the language of Systems Engineering
Reduce Cost Impact

Manufacturing Process Model in OMG SysML
• Contains all the necessary inputs needed for an ARENA® model – BOM, production schedule, resource,
process routings/times
• Shows the graphical representation of the BOM (Bill of Material) and each part’s process routing

OMG SysML to ARENA® Translation Process
9
OMG SysML model (.uml)
Formatted XML (.xml)
Access® database (.mdb)
ARENA® model (.doe)
ARENA® metamodel
(.ecore / .ecore_diagram)
UML®
metamodel (.url)
ATL translation (.atl)
XML definitions for ARENA®.
ATL translation code based on the
manufacturing DSL.
UML®/OMG SysML definitions.
XSL (.xsl)
Unformatted XML (.xml)
Java® (.java) 1
2
Using the Atlas Transformation Language (ATL) translation engine within the
Eclipse™ framework, translate the OMG SysML model with the ATL translation script. During translation, the model’s
UML constructs are compared with manufacturing DSL and the appropriate XML semantics for ARENA® are chosen.
Create an OMG SysML manufacturing model in MagicDraw® and then export the OMG SysML
file (XMI® export). XML format definitions.
Java® script to format XML file.
3
Using the Java® engine within the Eclipse™ framework, format the
translated XML to a format importable by Access with a Java® script. This
formats the XML data based on Extensible Stylesheet Language (XSL)
definitions.
4
Import the formatted XML file into a pre-built Access database. The database
contains tables and relationships that are recognizable by ARENA®. XML data is
placed in the appropriate tables.
5
Import the database into ARENA® discrete-event simulation
software. This will create a model for simulation and analysis.

Translating OMG SysML to ARENA®
10
ARENA® model
and statistics
• ARENA® manufacturing model can be simulated to identify system capabilities/constraints
• Production (overall/monthly) • Production lead times • Resource capacities • Bottlenecks
• Using these results, decisions can be made by manufacturing support teams

Who Uses Process Simulation?
• Boeing • Used ARENA® to model entire manufacturing and logistics
processes for 787 integration* – Assembly lines across the U.S. – Included suppliers of ~50 mechanical components – Simulated Dreamlifter usage for global logistics – Demonstrated potential effects of production ramp-up
• Many medium to large companies use process modeling**
• Examples: Toyota, Ford, GM, Lockheed Martin, NASA, EADS, Bombardier, Lufthansa, Honeywell, Goodrich, Cessna, Pratt & Whitney, HP, IBM, UPS
• Colleges and universities • ARENA® alone is used in over 150 programs in the U.S. and
over 500 worldwide

Benefits of Process Modeling Projects
• Tactical applications: allows for elements in a system to be adjusted without interrupting the current state
• Strategic applications: allows for new systems to be created and
examined before key decisions or investments are made • Provides leadership with a decision support tool to aid in the decision
making process • Generates data on which to base decisions • Helps to eliminate “best-guess” scenarios
• Identifies problem areas so effort can be focused where it will result in maximum benefit
• Helps communicate, promote change and receive buy-in from key stakeholders
• Gives stakeholders a better understanding of the entire system as a whole and the interactions that take place within the system
• A model is essentially a living and breathing Value Stream Map!

Integration Challenges
• Human Interface • Graphical user interface – “language” of systems engineers
• Formal methods/analysis – requires semantic precision • Integration
• OMG SysML is very flexible, graphical interface • AADL is semantically precise • MARTE, DARPA META translator: integrate OMG SysML-
AADL • XMI® implementation for tool interoperability • Automated connection with ERP (Enterprise Resource
Planning) systems • Need for producibility measures that can be applied
during system design (research) • Consistency checking of shared properties across
model environments (SAVI – Systems Architecture Virtual Integration)

How Can MBSE Address these Challenges?
• Promote and drive toward certified XMI interoperability • Cax-IF (Computer Aided “x” Implementor Forum) model?
• Architecture language mapping to STEP AP-233 • OMG SysML to AP-233 mapping – is it complete? • AADL to AP-233 mapping
• Develop a layered systems architecture “data interchange” model for interoperability between architecture descriptions
• Analogous to OSI (Open Systems Interconnection) model for communications architectures?
• Abstract systems modeling language at the top (MOF®?) • Concrete data storage model at the bottom (AP-233?) • Architecture models can take various forms
– Language – Instances – Database – File storage
