Research on weight factors of the evaluation indexes of cockpit display ergonomics

The ergonomic evaluation of cockpit display plays key role in the new-type cockpit development. In the previous research, the ergonomic evaluation indexes of cockpit display were build. This study is to determine the weight factors of the evaluation indexes of cockpit display ergonomics. For this purpuse, the order relation analysis method is proposed. With the aid of this method, 15 experienced pilots on active service who flied several types of aircraft were recruited as experts to be surveyed. The weight factors of evaluation indexes are calculated according to the investigation results. Then, the weight factors based on different numbers of experts are analyzed in order to study their reliability. The analysis results indicate that the weight factors are stable when the expert number up to some threshold value. Therefore the weight factors of the evaluation indexes calculated according to the investigation results can be used as the guidance to the design and evaluation of cockpit display ergonomics. © 2013 Asian Network for Scientific Information.
