Human-machine interface evaluation method based on grey interval relation membership degree

Due to the incompleteness and complexity of the evaluation information in the human-machine interface evaluation, it is difficult to evaluate the human-machine interface with the traditional evaluation methods. In order to overcome these problems, grey interval relation membership degree is applied in the field of human-machine interface evaluation in this paper. The concept of membership degree is imported and integrated with grey relation analysis in the method. By comparing the relation membership degree between the design schemes and the reference schemes, including the ideal scheme and the negative ideal scheme, the optimal scheme can be found. Based on the proposed method, a novel evaluation model of human-machine interface is set up and applied in the evaluation on computer monitoring and controlling interface of nuclear power plant. Results of the evaluation example prove that the proposed method for human-machine interface evaluation is reasonable and feasible.
