UML Based FMECA in Risk Analysis

International audienceToday, as systems become more and more complex, safety is becoming critical. Reducing the risk to an acceptable level with a complete risk management activity is necessary. This paper more precisely focuses on risk analysis; its demonstrate how the use of a risk analysis technic such as the Failure Modes, Effects and Criticality Analysis (FMECA) can be coupled to a object oriented system modeling process in order to guide the designer to exhaustively consider all potential risk, to increase the system security. For the system model, we chose the UML notation, which is now a standard in system and software engineering
