基于设计结构矩阵的大型复杂机场项目前期进度优化

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

摘要:

大型复杂机场项目前期阶段通常会存在任务复杂繁多且耗时较长的进度管理问题，针对这些问题，提出了前期工作管理思路，通过识别开工路径和建立前期工作概念模型梳理前期工作内容来确定关键工序。在此基础上，引入活动重叠思想，利用三元参数组建立基于设计结构矩阵（DSM）的工期计算模型，将关键工序导入到模型中，通过算法确定工序逻辑关系和缩短项目前期工作周期。以某机场项目为实例，将DSM矩阵有效地应用在项目前期进度管控中，为大型机场项目进度管理提供借鉴和指导。

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.
