SoSSE1: System-of-systems safety evaluation, pre-study
Purpose and goal
The project´s aim was to study method for safety analysis of komplex systems on an application of cooperative driving (platooning). A method based in systems theory, Systems Theoretic Accident Model and Processes (STAMP), was evaluated with promising results. Open challenges are integration of this method with today´s safety work in the vehicular industry and adaption of the method to larger and more realistic systems-of-systems. This project laid the foundation for a step in that direction.
Expected results and effects
The project demonstrated pros and cons of the STAMP method for safety analysis of systems-of-systems (SoS). As a result, a base was created for future method research within this area, as well as applications to more realistic SoS. These two tracks will be necessary to enable SoS technology to actually reach the market. The work also led to interesting discussions about how the method could be incorporated into current safety workflow in industry.
Planned approach and implementation
The project consisted of two parts, knowledge aggregation and safety analysis. The first part was conducted through self studies, mapping of relevant scientific publications, and a visit to MIT. The analysis was done in close cooperation between the project partners in order to capture both the research frontier and important technical aspects of the studied example application. The close cooperation and knowledge exchange was maintained through regular project group workshops (5 working days).
