Formal reasoning for fault-tolerant systems
Speaker: Larissa Meinicke, ITEE

Abstract:
A fault-tolerant system is one that is capable of performing safely or correctly in the presence of faults. Commonly, systems that are required to be fault-tolerant are composed of communicating hardware and software components that interact with their environment. Such systems are likely to have timing constraints. These characteristics suggest that reasoning about fault-tolerant systems involves reasoning about the interaction between discrete and continuous components and real-time constraints. Because most fault-tolerant systems are unable to function correctly (or in a fail-safe way) under all circumstances it is necessary to be able to reason about their reliability. Software reliability is a measure of the ability of a software component to satisfy its specification in certain operational conditions over a period of time. Formal methods may be used to specify, verify and derive programs in a mathematically vigorous way. Currently however, formal methods for reasoning about continuous concurrent program behaviour are underdeveloped compared to methods for reasoning about discrete concurrent behaviour. Also, most formal techniques for the development of programs do not facilitate reliability reasoning. It would be useful to be able to reason formally about system reliability in the same framework that that is used to develop and verify other program characteristics. The aim of this seminar is to construct a formal framework that can be used to reason about the behaviour and reliability of fault-tolerant systems. Specifically this work will explore ways in which the reliability of discrete and continuous real-time interacting software components can be expressed and reasoned about.
