Risk Propagation Model and Simulation of Schedule Change in Construction Projects: A Complex Network Approach

Abstract: Construction schedules play an important role in construction project management. However, during construction activities, risks may arise due to unexpected schedule changes, resulting in the ineffective delivery of projects. This study aims to reveal the law of schedule change risk propagation and to analyze the effects on the risk propagation through numerical simulations. First, construction projects are represented by activity-on-node (AON) networks. A model of risk propagation is then built based on a sus… Show more

“…A network is a common way of dissecting complex relationships between individuals. Some scholars have introduced complex networks to analyze risks in project risk management, such as risk propagation [22,[26][27][28] and risk evolution [29,30]. The PPR evolution network (PPREN) is essentially an interactive network driven by project interactions [17].…”
