舰船建造项目的规模和复杂性日益增大,预付款风险也得到了军方的日益重视.针对传统风险评估方法的不足,应用基于支持向量机的模型进行舰船建造预付款风险评估.建立了预付款风险评估指标体系,将支持向量机方法与BP神经网络方法进行对比,结果显示支持向量机可以很好的应用于风险评估.评估结果可供预付款管理决策时参考. The scale and complexity of the shipbuilding project are increasing day by day, and the advance payment risk is getting more and more attention from the military.According to the deficiency of the traditional risk assessment methods, the risk assessment of the shipbuilding pre-payment is established by using the model of support vector machine The evaluation index system of prepayment risk is compared with the support vector machine method and BP neural network method. The results show that the SVM can be applied to risk assessment well, and the evaluation results can be used as reference in the decision of prepayment management.
