Abstract: Considering the fast changing market demand in apparel supply chain, a XML-based middleware framework of the quick response system for apparel supply chain is presented. The system uses XML format to unify the data in all supply chain sectors, uses XML documents linking mechanism to integrate the heterogeneous data. The XML-based process design of the system and the computing model of the time delays in a order cycle are also introduced. By analyzing the reduction of time delays during the clothing and fabrics order process before and after the application of this system, the effect of the application of the system is verified: Through effectively sharing information among supply chain members, the order processing delay is eliminated, the manufacturing delay caused by upstream enterprises’ order processing delay and the fabric’s receiving delay are reduced, thus the goal of making quick response to the change of the market is achieved.
