Application of Fuzzy Theory to Comprehensive Evaluation of Cockpit Ergonomics

Cockpit is a complex man-machine-environment system composed by pilot, equipments and working environment. Many types of fuzziness are present in the cockpit system. These fuzziness should be accounted for when evaluate the ergonomics of cockpit system. In this paper, based on the theory of fuzzy, the quantification methods of evaluation indexes and the mathematical model of the comprehensive evaluation of cockpit ergonomics were proposed. This provided a theoretical basis and a practical approach for quantificational comprehensive evaluation of cockpit ergonomics. Utilizing the method, the geometry ergonomics of an aircraft cockpit was evaluated, and the results got approve from aviation engineering experts.
