A V&V masterclass from the experts.
Engineering simulation plays an increasing role in industry’s search for competitiveness and technology based innovation at every stage of the design, qualification and certification of products. Key decisions and product qualification & certification increasingly rely on virtual tests and digital simulation, creating a major paradigm shift in which the objective of physical tests is progressively moving from a demonstration of compliance to a reference for analysis validation. This trend in industry is shown through adoption of terms such as realistic simulation and virtual testing. This situation creates new responsibility for the engineer to guarantee the required confidence level.
This new approach requires secured processes for the verification and validation of models and analyses bringing evidence of their predictive capability. In particular, programme managers now require formal evidence on“simulation fit for purpose” on which they can build confidence and take decisions. In addition, the increasing situation for extended enterprise creates new constraints to guarantee safe and robust analysis processes.
At the same time, and due to the economic pressure, Verification & Validation activities are frequently seen as an additional cost that can easily be reduced or even fully cut, thus underestimating the induced risks. In addition, V&V is not easy to implement because of the diversity of involved persons: managers, simulation experts,test specialists, software developers and quality controllers, software vendors…
