Description
Summary:Conventionally correct problem definition value assessment of design functional element characteristic when in use gas turbine engine operation with common-cause failure on the base of symptom data dimensions is offered. Assigned task quasidecision synthesis was realized by smoothing functional extremum seeking regularization with A. N. Tihonov’s method for solution uniqueness and stability assurance relative to input data low variation. Regularization parameter choice was carried out in concordance with misalignment generalized principle. Evolutional method of assigned task decision was developed, this method founded on genetic algorithm application. Suggested method realization examples were considered by diagnostics problem decision for modern turbojet engine of regional passenger aircraft.
