Assessing the Vulnerability of Megaprojects Using Complex Network Theory

This article examines the vulnerability of megaprojects using complex network theory. The megaproject is first abstracted as a weighted directed network, after which a novel vulnerability metric is designed to quantify megaproject vulnerability. The proposed approach is then applied to a megaproject, which demonstrates its effectiveness in assessing vulnerability and identifying critical projects. Several protection strategies are finally proposed to enhance megaproject management. Overall, this study proposes a quantitative method to assess megaproject vulnerability that can reduce vulnerability and assist in the development of proactive risk approaches to ensure successful megaproject completion.
