基于贝叶斯网络的电力工程项目延迟风险研究
Research on schedule risk in power construction project using Bayesian network
-
摘要: 将电力工程项目发生延迟的各个风险因素通过BN模型进行了量化,结果显示,天气状况恶劣、项目时间计划过紧、技术工种能力低、缺乏先进设备仪器和供应商不能按时供货这5种风险因素会直接对项目的延迟产生影响;供应商不能按时供货、技术工种能力低、项目计划安排不当3种风险因素对项目的延迟十分敏感.项目经理应该重点控制这些敏感因素.Abstract: Schedule risk factors of power projects are quantified by Baysian networks (BN) model.Results showed that five kinds of risk factors such as poor weather conditions,tight project schedule,low-skilled jobs,lack of equipment and not timely supplier will directly impact on project schedule.Factors including not timely supplier,low technical work ability,improper plan arrangement are sensitive to project schedule,which should be the focus of control.
