The final objective of this project is to develop an efficient methodology for the optimization of industrial processes m.i.v. uncertainties. Uncertainties of the parameters influencing the process, as well as that of the design variables are themselves charged in the optimization cycle. It focuses on a variety of design variables and uncertainties. By adding uncertainty in the design cycle is the exploration of the design space (optimization) to be combined with the exploration of space stochastic (uncertainties) and submit accurate and efficient surrogate models to be developed.
