Overview of Fuzzy Simulation Techniques in Construction Engineering and Management

Simulation has long been used in the construction domain to model construction systems. Simulation techniques (e.g., discrete event simulation, system dynamics, and agent-based modeling) are well-equipped to handle complex systems; however, they fail to account for the subjective uncertainties present in many construction systems. Fuzzy logic, on the other hand, is a powerful tool for dealing with subjective uncertainty; therefore, integrating these two techniques is advantageous in modeling construction systems. In this paper, we present an overview of simulation techniques in construction. Then, we introduce the advancements that have been made by incorporating fuzzy logic with simulation techniques, and we propose methodologies for developing fuzzy simulation models. Finally, we discuss the process of choosing a suitable simulation technique for construction modeling. In addition to providing an overview of simulation techniques accessible to the construction domain, the main contribution of this paper is in introducing methods for integrating fuzzy logic with simulation techniques.
