About us

History

Since the beginning of 2005, a partnership of three companies has been working on building together a tool designed to perform uncertainty treatment and reliability analysis.

  • 2008: 4 releases (0.11.3-0.12.3) More distributions, more wrapping facilities

  • 2009: 2 releases (0.13.0, 0.13.1) Multithreaded wrappers, new algorithms, polynomial chaos expansion

  • 2010: 1 release (0.13.2) Windows port, modularization of the Python bindings, parallelization

  • 2011: 2 releases (0.14.0, 0.15.0) TBB and CMake support, sparse chaos, Numpy compatibility

  • 2012: 1 releases (1.0) Stochastic processes

Meetings

Each year a users day event is planned at the beginning of the summer allowing users to exchange on their use of the library and keep up with the new features. User days have been organized annually at EDF Lab Saclay (France) in June. Presentations can be found here .
