摘要:
提出克服传统计划评审技术(PERT)网络进度风险的局限性进度网络风险概率的改进算法.考虑网络路径之间相关性的约束条件,去除在规定工期内高完工率和高相关性的路径,利用多元正态积分技术,计算PERT网络进度风险概率.算例结果表明:与传统的蒙特卡洛模拟方法相比,该模型能够减少大量的计算时间,且误差较小,可忽略不计.
Abstract:
The risk probabilistic method of program evaluation and review technique(PERT)construction schedule network is presented, which overcomes the limitations of the current PERT. Considering the constraints of correlation between the network paths, removing the paths with high completion and high correlation in time limit for a project network, and using multivariate normal integral method, the network schedule risk is calculated. The results illustrate that: by comparison with Monte Carlo simulation methods, the new model is able to reduce greatly the computational time, the error is small and negligible.
