Abstract: In order to evaluate, classify and manage customer resources effectively, an evaluation index system for the steel enterprise's direct customer was established. In order to overcome the shortcomings of weight initialization of self-organizing map (SOM), a new classification method of K-SOM combining K-means algorithm with SOM was proposed. Then a customer classification method based on analytic hierarchy process (AHP) and K-SOM was provided. The characteristics of each type were analyzed and a set of suggestions on customer management was presented for different types of customer. Finally, a case study was provided to demonstrate the practicality and efficiency of the evaluation index system and methods.
