To handle stricter safety regulations combined with increasing complexity and shorter development cycles, it is necessary to consider safety aspects starting from the early phases of design. This paper presents an approach to link methods of safety analysis and modeling (SysML). Even though SysML and MBSE are common in the early stages of system design, there is a lack of methods integrating model-based design activities and safety analyses. Existing approaches either focus on particular tasks or build models after conducting separate safety analyses. Our presented approach, tailored to early stages of system design, introduces a "Hazard Analysis" SysML profile accompanied by a procedure for its application within a model-based safety analysis. It provides a preliminary hazard analysis and facilitates the systematic identification of safety-critical functions and components.

Increasing complexity of products and safety regulations combined with an increasing amount of variants complicates the process of safety analysis within systems engineering. Moreover, it is known that the early avoidance or prevention of failures saves costs and improves the quality. As methods of safety analysis, i.e. fault tree analyses require immense manual efforts and expert knowledge, the efficiency of these analyses has to be improved. Our paper thus presents an approach to generate and evaluate fault trees by the usage of matrix-based models. It is an approach tailored to the early phases of system design and provides a preliminary fault tree analysis. It automatically generates fault trees and evaluates them. Thus, it facilitates the efficient identification of safety critical elements and the assessment and comparison of alternative system architecture concepts. This paper provides a brief introduction to fault tree analysis and presents existing approaches to automate the generation or synthesis of fault trees. The limitations of these approaches during early stages of design are discussed and the need for a tailored approach is derived. The developed approach consists of four phases and six steps which each are explained in detail. The whole approach is validated within a small industrial case study and its benefits and limitations are discussed. The case study shows, that the approach successfully improves the efficiency of a preliminary fault tree analysis.
