Fault isolability with different forms of the faults–symptoms relation [PDF]
International Journal of Applied Mathematics and Computer Science, 2016 AbstractThe definitions and conditions for fault isolability of single faults for various forms of the diagnostic relation are reviewed. Fault isolability and unisolability on the basis of a binary diagnostic matrix are analyzed. Definitions for conditional and unconditional isolability and unisolability on the basis of a fault information system (FIS),
