Abstract: This paper deals with risk assessment in maintenance taking into account the interactions between all components of maintenance activity. These interactions reflect the complexity of this activity. The proposed methodology in this work combines UML language and MOSAR method. The UML-MOSAR methodology developed in this paper is successfully used to identify and to model the mechanism of hazard between sources of hazard and targets in maintenance activity. In addition, this methodology allows to quantify the criticality of risks and to treat them on a hierarchical basis according to several risk factors (human, technical, organisational and environmental). The UML-MOSAR methodology allows creating a database as an information system for learning from accidents and provides a comprehensive view that facilitates the understanding of the organisation of a maintenance activity and leads to more effective analysis of its safety.

Keywords: occupational safety; risk assessment; maintenance risks; complexity; Unified Modeling Language; UML; MOSAR; interaction; information systems; decision support systems; DSS; risk factors; accidents.
