The development of information processing systems requires§models, calculi, and theories for the analysis of§computations. Complex software systems are best constructed§in a careful, systematic, and disciplined structuring of the§development process. Starting from basic requirement§specifications in which all the relevant details are§formalized, the envisaged solution should be developed step§by step by adding more and more details and giving evidence§or formal proofs to show the correctness of the steps, until§a description of a solution is obtained that has all the§required properties.§The Marktoberdorf Advanced Study Institute 1992 presented§scientific highlights in approaches to the systematic study§ofreliable software and hardware systems using functional,§algebraic, and logical calculi. Leading scientists treated§the specification, development, verification, and§implementation of complex time-sensitive systems, such as§signal processing systems, process control systems, and§general software systems. The mathematical foundations of§specification and refinement were carefully treated, and§several formalisms for describing processes were introduced.§Emphasis was put on application-oriented descriptions§of signal processing systems with real-time dependencies.§Formalisms for reasoning about distributed causality-based§computations were presented and new styles of programming§leading to shorter and more expressive notations were§demonstrated.§This book is based on the Institute, and gives an impressive§demonstration of the state of the art and the essential§progress in our formal abilities to specify, refine, verify,§develop, and implement complex software systems including§embedded systems and hard real-time dependent systems.
