Integration Beyond Components and Models: Research Challenges and Directions

Recent research in embedded and cyber-physical systems has developed theories and tools for integration of heterogeneous components and models. These efforts, although important, are insufficient for high-quality and error-free systems integration since inconsistencies between system elements may stem from factors not directly represented in models (e.g., analysis tools and expert disagreements). Therefore, we need to broaden our perspective on integration, and devise approaches in three novel directions of integration: modeling methods, data sets, and humans. This paper summarizes the latest advances, and discusses those directions and associated challenges in integration for cyber-physical systems.
