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.

拟议的研究将开发混合系统动力学和离散事件仿真系统，以理解和管理复杂和动态的大型建设项目。考虑到施工中持续存在的成本和进度超支问题，非常需要提供一种有效的工具来促进更好地了解大规模施工。从本质上讲，PI 旨在识别大规模施工中各个流程之间的复杂相互作用，特别是通过施工作业与其周围环境之间的反馈（即相互作用），因为这些反馈导致了大规模施工中存在的严重动态和复杂性。我们采用混合系统动力学和离散事件仿真方法，以便有效地建模和分析这些反馈，充分利用系统动力学和离散事件仿真的潜力。换句话说，在保持离散事件模拟分析离散操作的出色能力的同时，PI 集成了系统动力学，以利用其在表示操作和上下文之间的反馈方面的优势。
