Engineering safety cases for autonomous vehicles is a complex and evolving challenge. Safety cases—structured arguments supported by evidence—are used to justify that a system is acceptably safe. In practice, these arguments are often developed using Goal Structuring Notation (GSN). However, as systems grow in complexity, so too does the difficulty of understanding and managing the interplay between different sources of uncertainty. In autonomous vehicle development, uncertainty arises at multiple stages: in the specification of system requirements, in the validation and verification processes, and in real-world operation. These uncertainties do not exist in isolation; they propagate through and influence the overall safety argument. Conventional tools for constructing and analyzing GSN-based safety cases offer limited support for visualizing these interactions, making it difficult for engineers to reason about the robustness and completeness of safety justifications.
Hier sorgst Du für Veränderung
This thesis explores the use of Virtual Reality (VR) as an innovative medium for representing and interacting with safety cases. By leveraging immersive visualization, the goal is to create a framework that allows users to intuitively explore GSN-based safety arguments and better understand how uncertainty affects them. The project will also lay the groundwork for integrating this visualization framework with a simulation environment (e.g., CARLA), enabling dynamic linking between simulated driving scenarios and the safety case evidence they support. This integration aims to provide a more tangible and interactive way of demonstrating how safety arguments respond to operational uncertainty. The thesis is expected to span approximately six months and will combine elements of safety engineering, visualization, and software development.
