Formal methods traditionally address the question of transforming software engineering into a mature engineering discipline. This essentially refers to trusting that the software-intensive systems that form our societyâs infrastructures are behaving according to their specifications. More recently formal methods are also used to understand properties and evolution laws of existing complex and adaptive systemsâman-made such as smart electrical grids or natural ones such as biological networks. A tribute to Professor Kaisa Sereâs contributions to the field of computer science From Action Systems to Distributed Systems: The Refinement Approach is the first book to address the impact of refinement through a multitude of formal methods ranging from Action Systems to numerous related approaches in computer science research. It presents a state-of-the-art review on the themes of distributed systems and refinement. A fundamental part of Kaisa Sereâs research consisted of developing Action Systems a formalism for modeling analysing and constructing distributed systems. Within the design of distributed systems Kaisa Sereâs main research focus was on refinement-based approaches to the construction of systems ranging from pure software to hardware and digital circuits. Presenting scientific contributions from renowned researchers around the world this edited book consists of five sections: Modeling Analysis Proof Refinement and Applications. Each chapter has been thoroughly reviewed by experts in the field. The book covers both traditional aspects in formal methods research as well as current and innovative research directions. It describes the transition from the strong theory of refinement to a methodology that can be applied in practice with tool support. Examining industrial applications of the methods discussed this book is a suitable resource for graduate students researchers and practitioners interested in using formal methods to develop distributed systems of quality. .
