Center node: "model based hazard and impact analysis"
  Abstract: Hazard and impact analysis is an indispensable task during the#R##N#specification and development of safety-critical technical systems, and#R##N#particularly of their software-intensive control parts. There is a lack of methods supporting an effective (reusable, automated) and#R##N#integrated (cross-disciplinary) way to carry out such analyses.#R##N##R##N#This report was motivated by an industrial project whose goal was to survey and propose methods and models for documentation and analysis of a system and its environment to support hazard and impact analysis as an important task of safety engineering and system development. We present and investigate three perspectives of how to properly #R##N#(i) encode safety-relevant domain knowledge for better reuse and automation, #R##N#(ii) identify and assess all relevant hazards, as well as #R##N#(iii) pre-process this information and make it easily accessible for reuse in other safety and systems engineering activities and, moreover, in similar engineering projects.#R##N##R##N#The first perspective focuses on the transition from informal to a#R##N#formal, model-based representation of knowledge about hazards and system requirements.#R##N##R##N#The second perspective provides a methodology to identify and treat#R##N#hazards based on a state-machine model of the considered system.#R##N##R##N#The third perspective shows a tool-supported procedure for modeling faulty behaviors of both, physical and software components in a qualitative way and for automatically determining their impact based on the structural description of the physical and computational/software parts of the system and a model of the environment.#R##N##R##N#All perspectives are shown in their characteristics and capabilities by means of a case study on a drive train in the commercial road vehicle domain.
