The project focuses on the development of a goal-oriented requirements engineering (RE) approach for collaborative system networks consisting of networked, dynamically interacting individual systems. RE is a part of computer science that deals with the systematic elicitation, analysis, documentation and management of requirements for systems in order to ensure their successful development. This is particularly challenging when the system is a collaborative system network, such as an autonomous robot fleet. Such networks are characterized by the fact that they are formed at runtime from individual systems whose interaction enables new functionalities that could not be realized by the individual systems in isolation. The aim of the "ZoREkS" project is to create a practical and industry-compatible RE approach that integrates existing modeling concepts, analysis methods and specification techniques and closes gaps. In particular, the approach takes into account the different types of target dependencies within and between the systems of a network. The integration and automated analysis of target fulfillment enables a consistent target modeling process.
