On one side, the enterprise could avoid manufacturing products which cannot be sold out and cut the production cost; on the other side, the enterprise could meet customer requirements as fast as possible. However, there is no perfect method for identifying the customization level till now. A new dynamic method is presented to solve this problem through gradual thought and management information system technology. The method is capable for promptly determining and alerting the product customization level.展开更多
