针对电信领域客户初始信用值获取问题,构建了一种信用评分模型,包括属性域和属性域信用权重的定义、信用权重的约束规则、初始信用度计算公式以及评价函数.该模型根据客户的基本数据和消费行为数据进行信用评分.在此模型的基础上,提出了一种基于蚁群算法的属性域信用权重分配算法,实验结果表明,该模型能有效解决电信客户初始信用评分问题.
A credit scoring model depending on customer application data and behavior data is developed in order to obtain the score of telecom customers' initial credit. The model includes : the definition of the attribute domain and its weight; some rules on the weight; the formula to calculate initial credit; and the evaluating function. Meanwhile, an allocation algorithm for customers' attribute weight is proposed using ants algorithm based on the model. Simulation demonstrates the rationality and feasibility of the model.
