工程项目进度-费用优化的占线风险补偿模型
发布时间：2018-10-19 16:53
【摘要】：针对关键活动发生不确定性延误的项目进度-费用优化问题,从占线策略与竞争分析的角度,设计了占线预赶工策略,给出了策略竞争比,同时分析了一般赶工策略与离线最优策略的关系,得到了关于一般策略费用与最优策略费用比值的三条性质,进而证明占线预赶工策略是最优确定性竞争策略.在此基础上,引入风险补偿模型,设计了具有不同风险偏好的风险补偿策略,使具有不同风险偏好的项目管理人员可以根据自己的偏好与预期选择最优的风险策略.
[Abstract]:Aiming at the problem of project schedule cost optimization with uncertain delay in key activities, a busy line pre-rush strategy is designed from the point of view of busy strategy and competition analysis, and the competitive ratio of strategy is given. At the same time, the relationship between general rush strategy and off-line optimal strategy is analyzed, and three properties about the ratio of general strategy cost to optimal strategy cost are obtained, and it is proved that busy line pre-rush strategy is the optimal deterministic competition strategy. On this basis, risk compensation model is introduced to design risk compensation strategies with different risk preferences, so that project managers with different risk preferences can choose the best risk strategy according to their preferences and expectations.
