Formal Specifications of Real-Time Requirements for Building Automation Systems

• A generic approach to the formal specification of system requirements is presented. It is based on a pool of requirement patterns, which are related to design patterns well-known in object-oriented software development. The application of such patterns enhances the reusability and genericity as well as the intelligibility of the formal requirement specification. The approach is instantiated by a tailored real-time temporal logic and by selecting building automation systems as application domain. With respect to this domain, the pattern discovery and reuse tasks are explained and illustrated, and a set of typical requirement patterns is presented. Finally, the results of a case study where the approach has been applied are summarized.
