Formal Techniques in Real-Time and Fault-Tolerant Systems: Second International Symposium, Nijmegen, The Netherlands, January 8-10, 1992. Proceedings [Paperback]

This book presents state-of-the-art research results in thearea of formal methods for real-time and fault-tolerantsystems. The papers consider problems and solutions insafety-critical system design and examine how wellthe useof formal techniques for design, analysis and verificationserves in relating theory to practical realities.The book contains papers on real-time and fault-toleranceissues. Formal logic, process algebra, and action/eventmodels are applied:- to specify and model qualitative and quantitativereal-time and fault-tolerant behavior,- to analyze timeliness requirements and consequences offaulthypotheses,- to verify protocols and program code,- to formulate formal frameworks for development ofreal-time and fault-tolerant systems,- to formulate semantics of languages.The integration and cross-fertilization of real-time andfault-tolerance issues have brought newinsights in recentyears, and these are presented in this book.ISL: An interval logic for the specification of real-time programs.- Duration specifications for shared processors.- A compositional semantics for fault-tolerant real-time systems.- Modelling real-time behavior with an interval time calculus.- Multicycles and RTL logic satisfiability.- Voluntary preemption: A tool in the design of hard real-time systems.- Observing task preemption in Ada 9X.- Real-time scheduling by queue automata.- Broadcast communication for real-time processes.- Analysis of timeliness requirements in safety-critical systems.- Verification of a reliable net protocol.- Mechanical verification of a generalized protocol for Byzantine fault tolerant clock synchronization.- Formal specification and verification of a fault-masking and transient-recovery model for digital flight-control systems.- On fault-tolerant symbolic computations.- Temporal logic applied to reliability modelling of fault-tolerant systems.- Specifying asynchronous transfer of control.- Protl‡
