Abstract
Fault tolerance so far was considered as a property of a system. In fact and instead we introduce a generalized algorithm of fault tolerance (GAFT) that considers fault tolerance as a system process. There is no doubt we have to analyze GAFT implementation using redundancy types of computer systems. Properties of GAFT implementation impact on overall performance of the system, coverage of faults, and ability of reconfiguration. It is clear that separation of malfunctions from permanent fault simply must be implemented and reliability gain is analyzed. A ratio of malfunctions to permanent faults is achieving 105−7 and simple exclusion from working configuration of a malfunctioned element is no longer feasible. In this chapter, we consider GAFT extension in terms of generalization and application for support of system safety of complex systems. Our algorithms of searching correct state, “guilty” element, and analysis of potential damages become powerful extension of GAFT for challenging applications like avionic systems, aircraft as a whole.
