桥梁施工进度控制随机网络解析算法

Analytic method of graphical evaluation review technique(GERT) network to control bridge construction progress

将 GERT网络技术应用于桥梁施工进度控制 ,通过分析矩母函数、梅森公式阐述了 GERT网络的解析法 ,提出确定工序参数的方法。建立了实桥机械成孔的随机网络图 ,并利用解析法原理计算分析 ,得出了实桥的合理工期 ,并与实际工期相符。

The analytic calculation of GERT network was presented by solving moment function and Mason formula to determine the construction procedure parameters. A GERT network model for an example bridge was developed. By this model, the resonable construction time limit was given, and it tollied with actual one.
