To Manage The Complexities Of Today’s Products, Engineering Teams Are Adopting Model-based Systems Engineering Practices


Optimizing System Performance


Model-Based Systems Engineering


Model-based Systems Engineering: Integrated Models From Requirements To System Realization

Document-Centric Systems Engineering

Documents the authoritative source of the system design

Models the authoritative source of the system design

• Requirements are text-based • Doesn’t adequately capture dependencies • Static, fragile, burdensome to maintain


• Textual requirements complimented by system models • Better visualize large amounts of complex data • Consistency of information • Automated traceability and verifications


Model-Based Systems Engineering with ANSYS Tools

Collaborative design and verification with Systems and Software Synchronization

Avoid duplication of efforts and inconsistencies between system definition and software design

System Architecture Software Design


Customer Case Studies and Testimonials

Eurocopter relied on fragile manual processes with drawing tools (Powerpoint, Visio, Excel..) to design systems use cases, functional decomposition and architecture

Example of architectural design realized by Eurocopter with ANSYS model-based system engineering platform

Customer Case Study

Problem • Transform conventional aircraft into UAV • Certify command & control architecture • Highly accelerated project schedule

Solution • Used SCADE Suite to automatically generate

and test all functions before putting on target hardware

Result • Development process accelerated by a factor of

three.

Our target is to have a complete simulation of our system on the host computer using SCADE Display and SCADE Suite then integrate all models and graphical interfaces
