Comprehensive evaluation model of users' satisfaction based on gray relational analysis and AHP

Abstract:

For the issue of less effective usability comprehensive evaluation on users' comments with uncertain information and complex evaluation indexes, a users' satisfaction comprehensive evaluation model is applied on usability research of production, which integrates gray relational analysis and AHP (Analytic Hierarchy Process). In order to enhance the objective of gray relational analysis, AHP method is used to determine the relative weights of evaluation index so as to establish comprehensive evaluation model of users' satisfaction model. With contrast experiment on the dataset of smart mobiles in different price, the satisfaction rank from our model is very similar to the one of actual sales. In addition, experiment result shows gray relational analysis can distinguish the satisfaction difference of productions more clearly. So above experiment results illuminate our model can comprehensively effectively evaluate users' satisfaction of production with incomplete assessment information
