Agent-Based Modelling as a Decision-Support System for Project Delivery Methods

Abstract

Cost overruns, schedule delays, claims, and disputes are regularly faced issues in most construction projects. While the reasons are numerous, one common cause is inappropriate selection of the project delivery method. Founding a project on an inappropriate delivery method not only disrupts schedule and cost plans, but also wrecks professional relationships and puts stakeholders’ futures at stake. Several attempts have been made to assist owners in selecting a suitable project delivery method. However, there is not much research that uses computer simulation to aid in the delivery method selection process. The aim of this study is to develop a decision-support system for project delivery methods. Agent-based modelling and simulation (ABMS) are employed to simulate different scenarios of different project conditions, allowing owners to select the best delivery method for each case. This decision-support system calculates scores for each delivery method and displays expected results that facilitate the selection process. A sample application is implemented to demonstrate the system. Finally, the conclusion and future recommendations are presented.
