Defect Classification Using Decision Tree

Product defect is any design fault, manufacturing failure or labeling matter which makes a product unsafe to use. It can be classified into several types, such as unacceptable dimensions, defects on the material, and others. However, due to the various factors that may cause the defect, it is not easy to pinpoint what actually causes the defect on the products. By using a decision tree, it is easier to determine the root cause of each defect as well as providing fast-response solution for each case. In the Quality Control (QC) department of a grinding wheel manufacturing company, the QC staffs need to answer some questions about the characteristics of the products. The decision tree certainly will help to find the root cause and it also generates the action for solving the problems. At the end of the session, the staff will get the decision whether the product can be accepted or should be destroyed.
