A method is developed to combine techniques of reliability and safety analysis with the Modelica language, which is now widely used for the modelling and simulation of technical systems. The method allows to perform a reliability or safety analysis on the system model that is created and used for simulation studies. The procedure automatically determines the so called minimal path sets or minimal cut sets of a system, its failure probability and critical components. The reliability and safety analysis methods are incorporated in a Modelica library that is established for the modelling and simulation of aircraft on-board electrical power systems. The recent trend towards a broader use of electric system technologies on commercial aircraft has motivated the creation of this kind of model library, which supports the conceptual design and optimisation of on-board electrical systems regarding power behaviour, weight, reliability and safety.
