From Semiformal Requirements To Formal Specification

This paper presents an approach for translating semiformal specification in formal ones. For a semiformal representation two approaches were taken: an approach from A. Fleischmann and a message sequence charts representation. A semiformal specification represented by one of these approaches can be translated to a formal specification in Focus, a a framework for formal specifications and development of interactive systems. This approach was applied on the case study during the project DENTUM between Denso Deutschland GmbH and the chair for Software & Systems Engineering at Technische Universität München. The goal of this project was to define a methodology for the model-based development of automotive systems. This methodology was evaluated by developing an Adaptive Cruise Control system with Pre-Crash Safety functionality
