 We based this scenario on a use case presented at the Conference on Prognostics and Health Management (PHM08) in 2008. The goal is to predict remaining useful life (RUL) of a set of turbofan airplane engines. This data was generated using C-MAPSS, the commercial version of MAPSS (Modular Aero-Propulsion System Simulation) software. This software provides a flexible turbofan engine simulation environment to conveniently simulate the health, control, and engine parameters.
