大型机场项目群进度的界面网络优化

包含多种类型单体项目的大型工程进度界面复杂,总工期延后的风险大.以上海浦东机场三期扩建工程为例,通过与项目总控人员访谈,总结出进度实施界面的划分原则.在划分原则指导下,利用WBS-Matrix对重点单体项目的任务过程进行分解和编码;利用界面网络算法对比分析关键界面点(IPs)的影响指数.在建立总进度纲要的界面点嵌入模型基础上,对比分析界面调整前后总工期的变化,证明进度界面优化模型的有效性.

Interface Network Optimization of Schedule of Mega Airport Programs

Mega construction projects (MCPs) with different types of project components have complex schedule interfaces, which increase the risk of delay in construction period. Taking the Phase III expansion project of Shanghai Pudong Airport as an example, the interface division principles of megaproject implementation were summed up for construction headquarters through the interview with project controlling consultants. Under guidance of the division principle: three pairs of main interface projects were identified, decomposed and encoded by using WBS-Matrix firstly. Secondly, the influence indexes of each key interface point (IP) were analyzed by using interface network algorithm. Finally, based on the IP embedding model for the overall schedule outline, changes of total duration due to interface optimization were compared, which shows that the effectiveness of the optimization model is proved.
