The Research of Customer´s Repeat-Purchase Model Based on Data Mining

It costs something like five times to serve a new customer than a regular customer. Regular customer is very import to enterprise. This paper proposes a model of customer´s repeat-purchasing. Customer behavior patterns are first identified using association rule mining. Then, the customer´s repeat- purchase model is identified by comparing two sets of association rules generated from datasets of different periods. The experimental results demonstrated that the method is effective.
