The needs to assess robust performances for complex systems have lead to the emergence of a new industrial simulation challenge: to take into account uncertainties when dealing with complex numerical simulation frameworks. The industrial aspect means that both the methodology and the numerical methods for uncertainty management have to be validated by the academic world and the certification authorities. In France, a generic methodology has emerged from the joint effort of several industrial companies and academic institutions. This joint effort has led to the development of an Open Source software platform dedicated to uncertainty propagation by probabilistic methods, named OpenTURNS for Open source Treatment of Uncertainty, Risk ‘N Statistics.
