Decision trees turn a lot of facts into decision trees that represent rules. The results achieved are rules that can be used to describe the processes associated with ship repair tender. The characteristics of the classified data can be obtained clearly, both in the form of a decision tree structure and rules so that in the testing phase it can help in analyzing ship repair tender.} }
