Contribution à la formalisation et à l'identification de la stabilité humaine au regard de la sécurité : application aux transports guidés

Abstract : The work of the thesis presents an original contribution based on the concept of human stability by identifying the associated risks as part of the safety system assessment. In a first part, the difficulties to take into account human factors in safety studies are highlighted and definitions of new ways for the integration of human factors based on the concept of stability are aimed. The second part presents a state of the art resting on stability and resiliency concepts. Although the stability concept is usually defined around a sustainable equilibrium point that induces a feeling of safety control during normal operation, it appears that the stable behavior of a human operator can lead to risks in certain situations such as hypovigilance, inattention and so on... The third part lays the foundation of human stability for risks assessment. Human stability is defined as the ability of the operator to stay in a stable operating state under specified conditions. This concept is then formalized and three modes of stability are developed(time, frequency and sequential modes). The following part proposes to apply this concept of human stability in the framework of ERTMS/ETCS. Then, some perspectives highlight the interest of human stability for the definition of risk indicators to assess system safety.
