A Dissonance Management Model for Risk Analysis


This paper proposes an original approach to analyze risks based on a dissonance management model called DIMAGE. A dissonance occurs when divergences between individual or collective knowledge occurs. The control of such dissonance relates to the risks associated to the current dissonance and the possible risks due to its treatment. The knowledge control consists in reinforcing knowledge regarding the results of the dissonance management. The dissonance control of the DIMAGE model takes advantage of positive and negative feedback from the other modules in order to improve the knowledge control. Stability profiles are used to analysed possible hazardous dissonance production associated to knowledge dimensions such as the expert knowledge level, the believe level on knowledge, the perceived, the interpreted or the real risks of a dissonance. A case study is discussed using these stability profiles with two dimensions: the knowledge content and the interpreted risks. It concerns the identification of possible dangerous dissonances related to the use of an automated tool to control the car speed. The stability profiles are used to model the possible evolution of knowledge and of the interpreted risks related to the control of several dissonances, and to identify possible problematic dissonances in terms of erroneous or conflicting knowledge or erroneous interpreted risks on safety or consumption.
