Study on Credit Classification of Practicing Qualification Personnel in Construction Market Based on BP Neural Network

The paper introduces BP neural network technology and establishes the evaluation index system of credit of practicing qualification personnel in construction market based on relevant characteristics. Then a classification model of the two kinds of practicing qualification personnel based on BP neural network technology is proposed. In order to test the validity of the classification model, the paper conducts an empirical study on 60 practicing qualification personnel and the results confirm that BP neural network is a simple and valid method which is appropriate for the credit classification of practicing qualification personnel, and it has settle well theoretical foundation for credit management of practicing personnel.
