Pre-Project Schedule Optimization of Airport Based on Design Structure Matrix

Abstract:

In the early stage of large-scale complex airport projects， there are usually many complicated tasks and time-consuming progress management problems. In order to solve these problems， this paper first proposed the management idea of preliminary work， and determined the key processes by identifying the starting path and establishing the conceptual model of preliminary work to sort out the contents of the preliminary work， based on which the idea of activity overlap is introduced， and the construction period calculation model based on design structure matrix（DSM） is established by using ternary parameter sets. The key processes are imported into the model， and the logical relationship is determined through the algorithm and the work cycle in the early stage of the project is shortened. Taking a certain airport project as an example， the DSM matrix is effectively applied in the early schedule control of the project to provide reference and guidance for the schedule management of large airport projects.
