MOSEL - MOdeling Specification and Evaluation Language

Abstract

In this paper the new model description language MOSEL (Modeling Specification and Evaluation Language) - developed at the Institute for Operating Systems at the University of Erlangen-Nuernberg - is described using many examples. To evaluate the performance of systems, like computer systems, networks, production lines and so on, the system has to be specified. Currently there already exist many different performance evaluation tools, which all have different input languages. The input languages for these tools are not only different, but they are also hard to use, since they all have a syntax which is oriented on the characteristics of the tool and not on the system which the user wants to describe. They are comparable with assembly languages for specific processors. The basic idea of the new language MOSEL is, to have only one language which is easy to use and reflects the real structure of the system the user wants to describe. MOSEL could be compared with a higher programming langu..
