Simulation modeling and sensitivity analysis of a tunneling construction project's supply chain

Abstract

Purpose – The purpose of this paper is to develop a simulation model capable of capturing the complex variables impacting the productivity of tunneling construction projects.Design/methodology/approach – Simulation modeling is used to construct high‐level models of construction supply networks in order to perform quantitative analysis, enabling planners to work out the embedded complexities of the system.Findings – This study presents a detailed simulation model of a real life tunnel construction project along with its supply chain of liner segments. Using this detailed model, a sensitivity analysis for the tunneling project shows the impact of chosen variables on the duration of a tunneling project; these results are used to verify the importance of considering the whole supply chain of a construction project in the planning stage.Practical implications – Effective quality control, consideration of the shortage of storage space, and anticipation of required lead time when placing the first order to achie...
