Risk Analysis Model Using UML and MADS Model

International audienceThe purpose of this paper is to propose a model of risk analysis which combines two tools belonging to a different context. These both tools are MADS (Model of Analysis of Dysfunctional Systems) and UML (Unified Model Language). The proposed method aims to integrate UML language, especially the collaboration diagram, in the MADS model. We represent the danger source system of MADS model with the collaboration diagram in order to define and model the scenarios of risk. The application of this method is illustrated with an example of a storage unit of chemicals. On the one hand, the proposed model provides a comprehensive view that facilitates the understanding of the organization of an industrial system, and on the another hand, it leads to more effective analysis of risks taking into account the interactions between the system components
