【摘要】 从工程项目风险管理理论入手,结合工程项目特点,将工程风险因素按层次关系分组形成递阶层次结构,构建了工程项目风险的评价指标体系。同时,建立了一个基于多级动态模糊综合评判与BP神经网络相结合的工程项目风险评价模型,以多级动态模糊评判为采样基础,用人工神经理论建立评价模型,采用反向传播(BP)算法训练网络,为工程项目风险评价提供了新思路。更多还原

【Abstract】 Based on management theory in engineering project risk and characteristics of engineering projects,causes of project risks are grouped on the basis of hierarchical relation.A hierarchical structure is formed and an assessment index system of engineering project risk is constructed afterwards.A risk assessment model for engineering project of dynamic fuzzy evaluation on multiple stages and BP neural network is established.Sampling basded on multi-stage dynamic fuzzy evaluation,an assessment model of BP training network is established according to artificial neural theory and a new idea for risk assessment for engineering project is put forward.更多还原
