Applying model-oriented approach for functional safety analysis management

Abstract

Functional safety analysis of complex systems is a large and important task. The more complex is the system, the more effort is required to analyze it. As the functional safety analysis starts very early in the system lifecycle, a lot of modifications in the analyzed system are to be expected, with the respective impact on the analysis. A software tool is required to facilitate the analysis and the implementation of changes while reducing the number of errors and minimizing the time analysts spend on the formalities. These goals can be achieved by model-based approach both to safety analysis and the specification. The model-based approach includes modelling of the “as is” process, optimization performed on the process model, and finally the implementation of the tool is based on the optimized process model.
