Safety assurance of software systems has never been as selected 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 cyberphysical nature of modern software systems—as exemplified by automated driving systems—mandates environmental uncertainties to be addressed and the resulting hazards to be mitigated. Furthermore, the abundance of statistical machine-learning components—massive numerical computing units for statistical reasoning such as deep neural networks—makes systems hard to explain, understand, analyse, or verify. Facing the challenge of these physical and statistical uncertainties, no single established method for software safety and reliability would suffice. Rigorous formal verification requires formal modelling of every detail of the target system, which is impossible under uncertainties. Testing suffers from uncertainties, too: notably, it is unclear to what degree of safety assurance a given test result should translate. Therefore, modern efforts towards safe software systems must unite techniques from different disciplines—formal methods, software science, software engineering, control theory, machine learning, etc.—in a way driven by real-world examples and supported by a common theoretical ground. This 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, analyse, 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). It consists of eleven chapters covering a variety of topics and techniques. Their diversity reflects the diversity of facets of safety assurance of modern software systems. Each chapter is written by experts of the corresponding field. Although there are loose connections between chapters, our intention is that each chapter is self-contained and can be read independent of others. The book’s exposition aims at giving high-level intuitions and use-cases of each technique, rather than technical details, with plenty of pointers for interested readers.
