Technical diversity of a complex system can be reduced using modularity and interface management. At the multi-disciplinary system level, this can be modelled using MBSE (Model-Based System Engineering) where typically the focus is on the system structure with the components and their interfaces. At the mono-disciplinary level this is further refined where each discipline uses its own tools and techniques to include more behavioural aspects.

During systems design, systems engineers would like to reason about systems feasibility as early in the process as possible. In this chapter, we present a model-based systems engineering (MBSE) method to support design decisions early in the process of systems development by quantitative information about important system qualities.

Sustainability embodies the concept of responsible management and care of the planet's resources and the well-being of both current and future generations. In line with the European Green Deal (EGD), the high-tech industry wants to be climate-neutral by 2050 and is actively engaged in exploring methods to integrate sustainability into its product development processes.

This technical report describes the learnings and the state of the Canvas project at the end of 2023, a collaboration between Canon Production Printing (CPP) and TNO-ESI. The topic addressed in this project is systems architecting for environmental sustainability (carbon footprint in particular) and circularity (ES&C in short).

The purpose of this document is to guide ESI research in Systems Architecting (SA) and Systems Engineering (SE), including collaborative studies. ESI aims to address the upcoming needs of the high-tech equipment industry. For this purpose, industry needs and consequential research outlooks have been elaborated in this document as a vehicle to support coordination and alignment of ESI research with the high-tech equipment industry.

An execution trace is a model of a single system behavior. Execution traces occur everywhere in the system’s lifecycle as they can typically be produced by executable models, by prototypes of (sub)systems, and by the system itself during its operation. An execution trace can be visualized and analyzed with various techniques, providing insight into the dynamic behavior, performance, bottlenecks, etc.

This report presents an overview of the work done by TNO-ESI and ASML in the Matala 2023 project. The main objective of the Matala project is to show how model-based testing can be used to improve efficiency and effectiveness of testing system-of-systems (SoS) in industry. The focus of testing is to ensure that systems are syntactically and semantically interoperable with each other, and deliver on promised functionality in an operational context.

When designing a system, one would like to have early information on how well a system design addresses stakeholder needs and concerns. Design Space Exploration (DSE) involves exploring the design space for system design candidates, including variants of specific system design aspects. For this, quantitative information on various system aspects is desired.
