Abstract

In the context of the project Software Platform for Embedded Systems 2020 (SPES2020) the conceptual foundations have been researched that allow to integrate the creation and analysis of safety models into the system design process for safety-critical and software-intensive embedded systems. Furthermore, a generic safety exchange format has been developed that enables the exchange of safety models between different modeling and analysis tools. In order to make the researched approach applicable in practice, it has to be integrated into those tools that are commonly used in the industry. This thesis deals with the development of a prototype for the modeling tool Enterprise Architect (EA) that is able to create and analyze safety models within this tool. The considered analysis technique is the fault tree analysis with component-integrated fault trees (C²FT). It’s demonstrated that C²FT models that are created in EA can be transformed into the generic safety exchange format and subsequently analyzed with the fault tree analysis tools of the Fraunhofer IESE and the commercial software FaultTree+ by Isograph Company. The greater part of this thesis consists of the documentation for developers including the introduced layered architecture as well as its implementation for EA. In addition, the existing C²FT meta-model is evaluated and the generic safety exchange format is extended in a way that on the one hand, further safety analysis techniques like Failure Mode and Effect Analysis (FMEA) can be easier integrated into the format and on the other hand, safety analysis can be performed for safety models that incorporate different analysis techniques at the same time.
