The proposed research will develop a hybrid System Dynamics and Discrete Event Simulation system in order to understand and manage complex and dynamic large-scale construction projects. Considering the persistent cost and schedule overruns present in construction, there is a tremendous need to provide an effective tool to facilitate a better understanding of large-scale construction. In essence, the PI seeks to identify complex interactions among various processes in large-scale construction, particularly through feedbacks (i.e., interactions) between construction operations and their surrounding contexts given that these feedbacks result in the severe dynamics and complexities present in large-scale construction. A hybrid System Dynamics and Discrete Event Simulation approach is pursued in order to effectively model and analyze these feedbacks, utilizing System Dynamics and Discrete Event Simulation to their fullest potential. In other words, maintaining Discrete Event Simulation's excellent capability to analyze discrete operations, the PI integrates System Dynamics in order to utilize its strength in representing the feedbacks between operation and context.
