Quality function deployment （QFD） puts the customer demands into multi-level deduction and commutation, and finally realizes the product design and technical design based on customer de- mands. In order to make up the subjectiveness and one-sidedness of QFD method during demands commutation, the analytic hierarchy process（AHP） is introduced into QFD. Through the AHP analy- sis of the customer demands, the importance degree of different customer demands is obtained. Final- ly by taking the multi-objective optimization design of planetary gear reducer as an example, the prac- tical effect of QFD-AHP design method is verified.文章介绍了质量功能展开（QFD）是一种将顾客需求进行多层次的演绎与变换，最终实现基于需求的产品方案设计及技术设计方法；为了弥补QFD方法需求变换中的主观片面性，将层次分析法（AHP）引入OFD应用过程中，对需求进行分析并得到不同需求的重要度，进而进行优化设计，以行星齿轮减速器的多目标优化设计为例，验证了AHP-QFD设计方法的实用效果。
