Study on the key quality parameter decision for multi-process by CART method

It has the features of data missing and nonlinear in multi-process manufacturing the quality data, the quality knowledge mining and key parameter decision-making based on CART method is carried out. Then the object data model, implementation method is discussed. At last, an application case in Alumina Ceramic Tube production is given which shows the CART method has strong applicability in multi-process manufacturing.
