Interface Network Optimization of Schedule of MegaAirport Programs

Abstract:

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 summarized for construction headquarters through the interview with project controlling consultants. Under guidance of the division principle, first, three pairs of main interface projects were identified, decomposed, and encoded by using the WBSMatrix. Secondly, the influence indexes of each key interface point (IP) were analyzed by using the 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 was proved.
