RIGOROUS DEVELOPMENT OF COMPLEX FAULT-TOLERANT SYSTEMS

Many software systems have reached a level of complication, mainly because of their size, heterogeneity and distribution, which results in faults appearing that cannot be traced back easily to the code. Some of these "faults" could also be unexpected program behavior that appears as a result of interactions between different parts of the program; this is commonly known as complexity. New methods, approaches, tools and techniques are needed to cope with the increasing complexity in software systems; amongst them, fault-tolerance techniques and formal methods, supported by the corresponding tools, are promising solutions. This book brings together papers focusing on the application of rigorous design techniques to the development of fault-tolerant, software-based systems.
