Aiming　at　product　configuration　problem　oriented　to　customer　requirements　analysis,　a　mapping　method　of　customer　requirements　by　integrating　Quality　Function　Deployment　(QFD)　and　rule-based　reasoning　method　was　put　forward.　The　mapping　relationships　between　customer　requirements　parameters　and　module　attribute　parameters　were　established　based　on　House　of　Quality　(HOQ)　of　QFD,　and　rule-based　reasoning　was　used　to　determine　the　target　values　of　technical　requirements　and　select　the　module　instances.　Then,　the　product　modular　configuration　scheme　set　was　obtained　to　meet　customer　requirements.　Finally,　the　proposed　method　was　verified　by　case　analysis.
