摘要
风险评估是项目风险管理过程中最困难、最耗时的一个过程,论文给出了项目风险评估的基本流程和评价方法,采用模拟生物神经元基本功能的BP神经网络技术建立了风险评估模型;并通过matlab神经网络工具箱学习训练该网络模型。经测试数据验证,结果比较准确,具有广泛的实用性。
Risk assessment of project is the most difficulty in the risk management of project.The procedure and method of risk assessment of project are introduced in detail and the relative appraisal model is built with BP neural network based on biology nerve cell.Through training of the matlab neural network tools and testing ,the model shows the preciseness and comprehensive practicability.
