  22. 22. Conclusions• Ability to create SysML models using manufacturing semantics.• Provide a central repository of manufacturing systems specifications to all stakeholders.• Automatically translate SysML models into discrete- event simulation in Arena which reduces the time of building simulation models in order-of-magnitude.

  23. 23. Future Opportunities with this Technology• Extend this technology to different application domains.• Possibility of translating SysML models into multiple simulation tools simultaneously (i.e., Arena, AnyLogic, etc.) and to different analysis models (i.e., discrete-event simulation, optimization, etc. )• Productize this approach to make it available for different companies to analyze their manufacturing systems.
