To support multifactor decision problems about usability evaluation,especially when studies fall short of comparable objects,a fuzzy synthetic evaluation model is explored in this paper. Grey relational analysis (GRA) is brought in the model to calculate weight vectors of the usability factors. And membership functions of a remark vector are constructed in the context of use of the operation interface. The present method is applied in usability evaluation of operation interface and is proved to be effective. The comprehensive usability gradation of the operation interface to good is 0.6164 that meets the requirements in practice.
Key words:    usability evaluation    fuzzy synthetic evaluation method    grey relational analysis    membership function
