Interacting Entities Modelling Methodology for Robust Systems Design

This paper describes the theoretical principles and the practical implementation of OpenCookbook, an environment for systems engineering. The environment guides and supports developers during requirements and specification capturing over architectural modelling and work plan development till validation and final release. It features a coherent and unified system engineering methodology based on the interacting entities paradigm. In order to implement it, a generic web portal was developed. Targeting embedded systems, it nevertheless was proven to be an effective tool for a wide range of other system domains. OpenCookbook can be tailored to the needs of a specific organisation as well as accommodate engineering standards like IEC61508.
