Reliability of reconfigurable control systems: a fuzzy set theoretic perspective

From a fuzzy set theoretic perspective, the paper analyzes the relationship of overall system reliability to performance requirements on subsystem modules in a reconfigurable control system. A performance measure is introduced, accommodating the multiple impairment parameter situation, in the form of coverage that indicates the likelihood of success in a reconfiguration action. This definition of coverage can also be used as a fuzzy ranking criterion for making the decision in selecting the most reliable control law
