La “Santé-Sécurité au Travail“ (SST) est au cœur des politiques d'entreprise et la judiciarisation de la société concourt à une inflation du nombre de textes réglementaires publiés chaque année. Les préventeurs sont donc confrontés au traitement croissant de données afin de rester en conformité. Ils se forment au droit et s'entourent de compétences interne (direction juridique) ou externe (bureaux de contrôle et de conseil) et se dotent de systèmes d'information. Ces derniers sont principalement des bases de données de "veille juridique" proposant des textes réglementaires accompagnés de commentaires. L'ensemble de ces données demeure complexe à interpréter et à exploiter en raison du nombre croissant de textes, de l'expertise nécessaire à fin de les comprendre et de la difficulté à s'assurer qu'ils concernent les activités de l'entreprise. Ce besoin peut être satisfait par le recours aux modèles et méthodes de l'intelligence artificielle. Parmi ceux ci, les concepts d'ontologies et de bases de connaissances ont été retenus. Une ontologie est un modèle d'un domaine particulier de connaissances réalisé dans un but précis. Un cas pratique de gestion des connaissances est décrit dans le cadre d'une expérimentation conduite avec une entreprise du domaine de la production d'énergie. / Occupational health and safety (OHS) is at the heart of corporate policies and the increasing trend towards litigation has contributed to the inflated number of regulatory texts published each year. OHS professionals are therefore faced with the need to process a growing amount of data in order to remain in compliance. They train themselves in law, draw upon internal expertise (the company's legal department) or external consultants (advisory and enforcement agencies) and equip themselves with information systems. These systems are mainly ‘judicial monitoring' databases that contain regulatory texts and associated comments. For the most part, this data is complex to interpret and difficult to exploit given the growing number of texts, the expertise needed to understand them and the difficulty in being sure that they are relevant to the activities of the company. This need for clarity may be met by models and methods from artificial intelligence. Amongst these, we have selected the concepts of the ontology and the knowledge base. An ontology is a model of a particular domain of knowledge created for a specific purpose. A case study of the knowledge management is described as part of an experiment with a company in the energy production sector.

This exploratory research is based on an objectivist epistemology with a positivist theoretical perspective that deployed concurrent mixed methods (MMR) design through a quantitative administered survey alongside an in-depth qualitative analysis through interviews exploring the perspectives of leaders on EHS leadership and governance. The research literature review focused on EHS leadership, corporate governance and strongly related topics. This MMR research employed both an expert panel-validated survey and a semi-structured interview protocol which explored 9 themes which emerged from the literature review including EHS/Safety Leadership; Risk Management; Influence and Accountability. Due to pragmatics relating to the number of leaders accessed (N=30) the statistical analysis is limited to descriptive type statistics. Almost all respondents supported the monitoring role of the Board of Directors (BoD), but disagreed that the BoD should play an active role in risk management. Comparisons are drawn between the Oil and Gas and non-Oil and Gas organizations with interesting results especially in matters relating to risk management. Structured thematic content analysis yields that Safety Culture; Leadership; Influence and Accountability were the three leading themes accounting for just over 50% of the responses analysed. Many sub-themes have also emerged and are discussed. A Model of EHS Leadership and Governance was created and is presented which positions themes and factors that influence monitoring of EHS performance and ultimately risk management. The research can be considered as a unique contribution as a relatively small body of currently published work in this subject area, both globally and more so in the GCC.

This master’s thesis focus on the analysis of work conditions and risk assessment for specific company and specific project. It brings better condition to current action in health and safety area during all working activities. Emphasis is placed on safety of work and health protection of workers. The work provides information about theory of security work explores its practical application in the organization and gives a view into risk assess and risk management.
