Modelling Rules for Engineering Under Safety aspects (MORFEUS)

Alt Text

In German, "Sicherheit" cannot be clearly differentiated between security and safety as it is in English. The term functional safety has become established here, but indicates the safety of a function and limits the view to safety. In order to be able to consider safety more completely, it should be considered more holistically in relation to systems in its environment. It is also seen as part of system development and should be integrated at an early stage.

In system development, SysML has established itself as a possible language for describing systems. Since 2018, the “Safety and Reliability for UML” Working Group has been working on integrating the methods for describing safety-relevant aspects of models such as Functional Hazard Analysis (FHA), Fault Tree Analysis (FTA) and Failure Mode Effect Analysis (FMEA) into the modeling language.

This working group serves as a forum for exchanging experiences and working on common issues.

Current Goals and Topics

The following goals are in focus:

  • Supporting systems engineering in the model-based development of safety-critical systems
  • Developing the current state of knowledge of existing methods and approaches
  • Creation of a conceptual model
  • Validation of the model using existing methods and practical examples

Preparation of the topic for the members of the GfSE:

  • Identifying and developing guidelines
  • Access to workshop resources
  • Mediating between users, tool manufacturers, consultants and standardization committees

Current Topics

  • Definition of common safety terms
  • Definition of a conceptual model for integration into the SysML standard
  • White paper on the safety of highly automated systems
  • White paper on the topic of safety patterns
  • Creation of guidelines for FHA, FTA and FMEA?
