Development of a Cell-based Simulation Model for Earthmoving Operation using Real-time Location Data

Simulation is a proven technique for effective construction site layout planning and resource optimization. Historical data is used as input for task durations in traditional simulation approaches. This data is fed into activity cycle diagrams which do not consider spatial constraints. Cell-based simulation with real-time location data can be implemented for more realistic modeling and incorporating spatial changes on the site during project execution. Despite the potential, very little research has been done towards it. The objective of this research is to develop a framework of utilizing real-time data for spatial simulation of cyclic activities on a construction site. Continuous data was collected using Global Positioning System and cell-based simulation model was developed for spatial consideration of earthmoving cycles. The potential of analyzing and visualizing the effects of varying resource combinations on productivity and traffic congestion on site were explored. The approach will aid in increasing insight and awareness for decision making in resource management, site layout and internal traffic control plan. It will also serve as an education and training tool for project managers.
