In order to improve the reasoning efficiency of PC (Product Configuration) and reduce the diversity of variant product in manufacture enterprise

the product reconfiguration technology in PC for manufacturing is studied.In view of the similarity and centrality of user’s requirements in some conditions

the reconfiguration study begins from the existing configuration results to resolve the customized configuration problem.On the basis of PC design based on generic product structure

a description method of configuration results with XML format is proposed.Based on this work

a product reconfiguration method and its key algorithms are given

in which the configuration page is used as the minimal processing unit.The experiment result shows that the above reconfiguration method can reduce the reasoning time with the reconfiguration proportion increasing.
