Application of grey relational analysis in cognitive ability evaluation of operator

摘要

It was proposed that grey relational analysis method was adopted to comprehensively evaluate the cognitive ability of the operator aiming at the condition that human cognition ability has characteristics of multi-factor, incomplete information and the like, and example analysis was carried out. Firstly, comparison sequence and reference sequence were established according to the influence factor level value of the evaluation object, the correlation coefficient between the influence factor and the optimal index of the evaluation object was calculated, the weight of the evaluation index was combined in order to calculate the correlation degree, and all evaluation objects were sequenced according to the correlation degree. The results show that the method is flexible and accurate with strong maneuverability.
