Quality Function Configuration (QFD);  multi-objective decision-making;  Envelopment analysis (DEA).

Based on the analysis of quality function configuration, a quality function configuration model based on data envelopment analysis method is proposed. The model makes full use of the input and output information of the quality house, weighs and optimizes various contradictions and conflicts in the quality house, and judges and evaluates the technical characteristics in new product development or old product transformation by analyzing the production effectiveness of each decision-making unit, so as to help product developers make effective decisions and make the products they design meet the needs of customers to the greatest extent. Case studies show that the model is feasible and effective.
