Abstract: In order to effectively support mass customization production, Product Family Architecture (PFA) needed constant evolution. To tackle this problem, PFA evolution based on customized product data was presented. Part change and structure change were two factors causing PFA evolution. Part change leading to PFA evolution was discussed in particular. Firstly, part was modeled with non-numerical information and numerical information. And then similarity between part instance in customized product and part model in PFA was identified, the parts similar to those in PFA were eliminated so as to generate new type of part. Secondly, the amount of new part used in customized product was calculated. Only those new parts which satisfied threshold condition would be appended to PFA. As a result, PFA evolution could meet with individual demand of customers. Finally, the effectiveness of these principles and methods were verified by product data of a textile machine company.
