Integration of SysML with Trade-off Analysis Tools

Changes in technology, economy and society create challenges that force us to rethink the way we develop systems. Model-Based Systems Engineering is an approach that can prove catalytic in this new era of systems development. In this work we introduce the concept of the modeling "hub" in order to realize the vision of Model-Based Systems Engineering and especially we focus on the trade-off analysis and design space exploration part of this "hub". For that purpose the capabilities of SysML are extended by integrating it with the trade-off analysis tool Consol-Optcad. The integration framework, the implementation details as well as the tools that were used for this work are described throughout this thesis. The implemented integration is then applied to analyze a very interesting multi-criteria optimization problem concerning power allocation and scheduling of a microgrid

Aspect-oriented modeling of business processes

Concerns such as compliance, auditing, activity monitoring or accounting need to be addressed in the early stages of modeling and not only at the implementation or execution levels. AO4BPMN is an aspect-oriented extension of BPMN that facilitates the modularization of crosscutting concerns
