Abstract: In CRM，customer segment is the base of other function.Completely thinking over the customer’s lifecycle value，it develops a novel customer segment method that combines group decision-making and data mining techniques.Firstly，it applies the analytic hierarchy process to determine the variables and the relative weights of every variable.Then，clustering techniques is applied to do customer segment according to the weighted variables.Finally，the data of an enterprise is used to validate the new method.The experimental results demonstrate that the method is effective for customer segment.
