In the Hybrid Analysis project, we investigated combining static and dynamic information in order to analyse large-scale industrial software. Our goal was to assess the value of adding dynamic data to the static analysis that is already being done on a routine basis and to discover best practices for performing such hybrid analysis.

High-mix low-volume (HMLV) production systems are crucial for enabling mass customization to meet diverse and rapidly changing customer demands. These systems require optimization across various time scales to handle fluctuations in job mix and ensure robustness against unforeseen changes, such as rush orders.

In applied research projects, we want to create impact by developing innovative solutions, and land them in the organization. Successfully landing innovations typically requires a direct collaboration with stakeholders in the organization. They need to adopt the results in the system they develop or embed them in their systems development process and way-ofworking.

High-tech cyber-physical systems (CPS) are becoming increasingly diverse: they may have many variations and configurations, might be part of product families, and may be highly customizable. Additionally, CPSs tend to continuously evolve—have variation in time—for example due to technology updates, changing demands, or changing requirements.

The performance of cyber-physical systems (CPS) is a determining factor for their success and often needs to be guaranteed. When performance issues occur, their analysis and the identification of the root-cause should be fast. Typically the analysis requires the relation of system observations (i.e., tracing) to design and implementation artifacts.

The functionality that we use as organizations and citizens increasingly arises from a complex interplay of man-built systems, individuals and organizations, and the environment. It is a challenge to get the desired functionality and features consistently, reliably and affordably, without unwanted side effects.

To meet the goal of net-zero greenhouse gas emissions by 2050, the Netherlands must scale its electricity grid by a factor of five. Limited building space, a lengthy process to obtain building permits and shortage of skilled labor pose a major constraint. This paper explores how modular building, embedded within a Systems Engineering (SE) and Product Line Engineering (PLE) approach, can help accelerate electricity grid extension, and, ultimately, the energy transition.

The high tech equipment industry in the Netherlands develops cyber physical systems that are increasingly enabled by software. The interplay between Systems Engineering (SE) and Software Engineering (SWE) remains persistently problematic. Organisations report recurring symptoms such as integration issues, emergent behaviour problems, rework, delays, and budget overruns.
