Safety assurance of software systems has never been as imminent a problem as it is today. Practitioners and researchers who work on the problem face a challenge unique to modern software systems: uncertainties. For one, the cyber-physical nature of modern software systems as exemplified by automated driving systems mandates environmental uncertainties to be addressed and the resulting hazards to be mitigated. Besides, the abundance of statistical machine-learning components massive numerical computing units for statistical reasoning such as deep neural networks make systems hard to explain, understand, analyze or verify.The book is the first to provide a comprehensive overview of such united and interdisciplinary efforts. Driven by automated driving systems as a leading example, the book describes diverse techniques to specify, model, test, analyze, and verify modern software systems. Coming out of a collaboration between industry and basic academic research, the book covers both practical analysis techniques (readily applicable to existing systems) and more long-range design techniques (that call for new designs but bring a greater degree of assurance).The book provides high-level intuitions and use-cases of each technique, rather than technical details, with plenty of pointers for interested readers.

From the Foreword"Getting CPS dependability right is essential to forming a solid foundation for a world that increasingly depends on such systems. This book represents the cutting edge of what we know about rigorous ways to ensure that our CPS designs are trustworthy. I recommend it to anyone who wants to get a deep look at these concepts that will form a cornerstone for future CPS designs."--Phil Koopman, Carnegie Mellon University, Pittsburgh, Pennsylvania, USATrustworthy Cyber-Physical Systems Engineering provides practitioners and researchers with a comprehensive introduction to the area of trustworthy Cyber Physical Systems (CPS) engineering. Topics in this book cover questions such asWhat does having a trustworthy CPS actually mean for something as pervasive as a global-scale CPS? How does CPS trustworthiness map onto existing knowledge, and where do we need to know more? How can we mathematically prove timeliness, correctness, and other essential properties for systems that may be adaptive and even self-healing? How can we better represent the physical reality underlying real-world numeric quantities in the computing system? How can we establish, reason about, and ensure trust between CPS components that are designed, installed, maintained, and operated by different organizations, and which may never have really been intended to work together? Featuring contributions from leading international experts, the book contains sixteen self-contained chapters that analyze the challenges in developing trustworthy CPS, and identify important issues in developing engineering methods for CPS.The book addresses various issues contributing to trustworthiness complemented by contributions on TCSP roadmapping, taxonomy, and standardization, as well as experience in deploying advanced system engineering methods in industry. Specific approaches to ensuring trustworthiness, namely, proof and refinement, are covered, as well as engineering methods for dealing with hybrid aspects.

Smart cities are a new vision for urban development. They integrate information and communication technology infrastructures – in the domains of artificial intelligence, distributed and cloud computing, and sensor networks – into a city, to facilitate quality of life for its citizens and sustainable growth. This book explores various concepts for the development of these new technologies (including agent-oriented programming, broadband infrastructures, wireless sensor networks, Internet-based networked applications, open data and open platforms), and how they can provide smart services and enablers in a range of public domains.The most significant research, both established and emerging, is brought together to enable academics and practitioners to investigate the possibilities of smart cities, and to generate the knowledge and solutions required to develop and maintain them.

This book constitutes of the proceedings from the 28th International Conference on Engineering of Complex Computer Systems, ICECCS 2024, held in Limassol, Cyprus, during June 19–21, 2024. The 18 full papers and 4 short papers presented here were carefully reviewed and selected from 68 submissions.

This book constitutes the refereed proceedings of the 11th International Conference on Rigorous State-Based Methods, ABZ 2025, held in Düsseldorf, Germany, during June 10–13, 2025.The 10 full papers, 4 short papers, 2 PhD Symposium papers and 5 case study papers presented in this book were carefully reviewed and selected from 33 submissions. The proceedings also contain one invited talk in full paper length. The ABZ conference series is dedicated to the cross-fertilization of state-based and machine-based formal methods. Abstract State Machines (ASM), Alloy, B, TLA, VDM, and Z are examples of these methods. They share a common conceptual foundation and are widely used in both academia and industry for the rigorous design and analysis of hardware and software systems. The ABZ conferences aim to be a forum for the vital exchange of knowledge and experience among the research communities around different formal methods.
