Towards a Method Evaluating Control Actions in STPA-Based Model of Ship-Ship Collision Avoidance Process

As system-theoretic methods of safety assessment are developed, certain aspects of them remain under-explored, including the question of prioritizing one control action’s adequacy over another. This paper investigates this feature based on an analysis of a process of merchant vessels’ collision avoidance. We first elicit experts’ views on the structure of the process and importance of particular interactions occurring therein. Thence, we analyse...
