Abstract: This paper analyzes a great deal of charge data that a supply heating company provides. It establishes a data mining model for customers by constructing a data warehouse and using the data generalization, and finds out some association rules from the frequent itemsets and some features of time to pay by using decision tree, so that it can draw a conclusion that different customers have different custom of charge.
