Important results from the project
The goal was to be able to analyze safety in new complex systems, by building an easy-to-use tool for modeling and analyzing safety architectures on top of Matlab Stateflow. Fulfilled sub-goals: - create the tool and release it as freeware - evaluated it on case studies at Scania - use it in sharp projects where we have shown that proposed new architectures are safe. These new architectures have potential to save a lot of money in product costs. - scientific articles and dissertations
Expected long term effects
Long-term effects are more cost-optimized safety architectures. These architectures have less redundancy and have cheaper components, but through analysis by our method and tools, still have been verified to be secure. These cost-optimized architectures increase competitiveness.
Approach and implementation
The project was carried out through collaboration between Scania, RiSE and KTH. One success factor was that the project and supervision were led by an adj Prof who has strong roots in both academia and at Scania. Another success factor has been that the project has been driven by case studies throughout. We have iteratively tested methods and tools on a case study, evaluated what did not go well, then improved methods and tools, then new case studies, etc.
