A generic off-line approach for dealing with uncertainty in production systems optimisation

International audienceThis paper addresses production systems optimisation in uncertain context. A standard framework for solving such type of problems is depicted in a 3-step approach. The two first steps are addressed in this paper. They consist of off-line characterisation of the problem and calculation of solutions with some desired performance. A generic approach to implement these off-line steps is introduced in this paper. This approach relies on calculation of robust off-line solutions. A generic framework of robustness is defined. Then five standard optimisation problems are derived and related to the so called stability and sensitivity analysis. This generic approach is then applied to a multi-purpose machines problem
