Towards Early Emergent Property Understanding: Merging Behavior Space Exploration and Model-based Software Engineering
During early phases of complex systems engineering typically many structural and behavioral aspects are unclear. In particular, when it comes to constraints on the result of interactions between distributed components (emergent properties) current software engineering approaches provide limited support. Therefore, we propose an extension to current software models for describing the goals of interaction rather than the underlying decision logic. Further, we propose a generic algorithm for obtaining goal-oriented behavior. Finally, the concepts are evaluated in a case study.

A Rapid Prototyping Approach for Smart Energy Systems Based on Partial System Models
A key success factor for building smart control software for today's energy systems is a precise understanding of their behavioral requirements. However, current engineering approaches lack the possibility to validate these requirements in early phases of development. The validation is hampered by the difficulty estimating the impact of requirements on the overall system behavior before a complete system model is built. To overcome this situation, we propose a model-based rapid prototyping approach based on partial system models enabling early validation of behavioral requirements through tool-supported behavior estimation. For evaluating the approach we demonstrate our approach through a case study showing the interaction between customer and software engineer over three iterations. Finally, the approach is discussed with respect to modeling effort and required model resolution.
