GAFT Generalization: A Principle and Model of Active System Safety

Fault toleranceFault tolerance so far wasActive system safety considered as a property of a system. In fact and instead we introduce A Generalized AlgorithmActive system safety algorithm of Fault ToleranceFault tolerance (GAFT) that consider fault toleranceFault tolerance as a system process. There is no doubt we have to analyze GAFT implementation using redundancyRedundancy types of computer systems. Properties of GAFT implementation impact on overall performance of the system, coverage of faults and ability of reconfigurationReconfiguration. Clear that separation of malfunctions from permanent fault simply must be implemented and reliabilityReliability gain is analyzed. A ratio of malfunctions to permanent faults is achieving 105–7 and simple exclusion from working configuration 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.
