Many technical systems need to guarantee a specific level of availability. Therefore, predicting the availability of a system early is often necessary. In this thesis, we suggest a method for specifying and analyzing availability requirements of a system. We extend an existing artifact model for software-intensive systems by additional artifacts capturing availability properties. We furthermore provide a method that supports the systematic application of our artifact model. Finally, we evaluate our approach in an industrial case study and report on prototypical tool support.
