Abstract :
The paper puts forward the idea of using fault tolerance refinement patterns to assist system developers in disciplined application of software fault tolerance mechanisms in rigorous system design. Two patterns are proposed to support a correct introduction of recovery blocks and N- version programming into a system model; these are formally defined and their correctness proven. We also discuss several important issues involved in the use of these patterns in engineering systems, including tool support and pattern composition.
