This paper presents an analysis of models used for software system requirements. A range of models have been chosen to demonstrate the diversity of notation, application and intention and they have been considered separately from the methods used for their creation. A set of criteria is established as a basis for comparison of the chosen models. The criteria are intended to cover aspects of a requirements model which allows for assessment of its suitability for a particular application. Various classes of models have been distinguished and a comparative overview of those classes is given. The paper provides information for a reader who is looking for a suitable model for a particular domain. Information is presented that will be of use to researchers and practitioners who are interested in the provision of tool support for requirements engineering. It also serves as an introduction to the research area of software system requirements models.
