QR (Rapid Response System) is a supply chain management strategy that originated from American clothing industry. From the topic of the e-commerce exam. 1982, a study on this industry shows that the time of clothing in the supply chain needs 66 weeks, and such a long detention time has caused huge costs, so it is impossible to accurately predict the actual demand. To reduce the loss caused by too many or too few products in the supply chain, it is necessary to shorten the time of products in the supply chain. In order to improve the competitiveness of products, American textile and clothing industry began to adopt QR strategy.
