ABSTRACT
The recent worldwide development of Bridge Management Systems and the extension of Life Cycle Cost considerations as performance studies make Civil Engineering enter the wide field of the domains where process optimization is the basis of productivity. Indeed, these domains are non-exhaustively military, industrial, aero naval and nuclear fields. No one can ignore the risk management as a foundation in those activities. The FMECA method appeared as a standard in military field in 1953, then adaptation of the FMECA to machines and processes came in the industry. Finally, aero naval and nuclear fields are well known for their failure rate normalized limitation to 10−7. Therefore, it is normal to consider that the optimization science of the civil processes and costs cannot extend itself without going though risk assessments, and that techniques used for surveillance and maintenance design would avoid it.
