Abstract

The development of safety-critical systems requires the hazard identification and risk assessment during early development phases. For this task, Preliminary Hazard Lists (PHL) or Preliminary Hazard Analysis (PHA) can be used. Innovative systems can be found considering those hazards in a smart systems engineering. During development, the problem may arise that the information exchange is document-based only. If document-based development is unavoidable, an approach is required to enable a seamless data exchange among development tools. We describe a seamless approach used in FLHYSAFE during the Preliminary System Safety Assessment. Due to the widespread use of Excel, a template is created to perform the Functional Hazard Analysis (FHA). FHLYSAFE is used as an example project to show how the FHA can be integrated in the applied model-based development. Additionally, results of the seamless lean FHA as well as findings in system development are described.
