3. Illustrating the method: the Challenger case

This section presents the test carried out on the matrix calculation model for the implementation of the feared events evaluation step. It is based on feedback from the Challenger accident (explosion of an American space shuttle on January 28, 1986, killing 7 people). Analysis of the accident enabled us to establish the various hazard processes that led to the accident. The system taken into consideration is that of NASA. The hazard processes were designed to be consistent with the overall risk analysis approach presented above.

In the end, we obtained 23 hazard processes (see table 6 ).

• The matrix of impacts between the various hazard processes obtained for the Challenger accident is illustrated in table . This table has been filled in...
