A mixed models integration approach, both top-down and bottom-up, is presented. Top-down approach is justified by the will to offer a generic and structuring framework; due to the complex nature of the problematic, a systemic approach has been chosen. Bottom-up approach concerns information extraction from database, including knowledge of experts. This mixed approach has been applied to build common representation of accident scenario for accidentologists and designers of new safety systems.
