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.
