My focus today:My focus today:
• What does it mean “to integrate manufacturing with design?”
• What does it mean “to integrate manufacturing system design with manufacturing system simulation?”
• How can we make these two things happen?

Design to Manufacturing IntegrationDesign to Manufacturing Integration
• EBOM to MBOM Transformation
• Or “EBOM to WBS”
• More than “interoperability” or “converting a file format”; “how” based on “what”– Sourcing (=> logistics, cost, schedule …)– Resource organization/assignment (=> mfg cost)– Inventory/WIP positioning (=> cycle time …)
13
R&D StrategyR&D Strategy
• Conform factory design to product design– Functional design– Detailed design
• Recognize process planning as the “design to manufacturing” bridge
• Manufacturing as part of a federated “enterprise” model
• NOT structure—NIST CMSD is one start toward a practical standard for structure
• Modeling Control!– State machine/Sequence Diagram?– Activity Diagram?– Executable UML?– What’s the fundamental conceptual model?
• Moore machine• Mealy machine• DEVS• Other?

If you want to play this gameIf you want to play this game
• Formal languages– SysML is our bet
• Model transformation– MOFLON? QVT? We’re not completely sold…
• Implicit/Explicit paradox
• Domain specific languages– Profiles of SysML
49
ConclusionConclusion
• SysML and formal models (potentially) enable an unprecedented integration of manufacturing system “description” and manufacturing system simulation (like the MCAD and ECAD domains now enjoy)
• Rationalization of factory control remains the fundamental challenge—how can we reconcile the complexity of real factory control with the need to create (in finite time and finite cost) useful factory simulations?

Main Questions Addressed by ProjectMain Questions Addressed by Project
• Process: How do we include engineering analysis tools in the MBSE process?
• Representation: How do we represent engineering analysis models in SysML?
• Execution: How do we integrate engineering analysis tools & models with SysML tools & models?
