Abstract

Tower cranes are considered to be one of the most important equipment in large construction projects. The layout planning of tower cranes that defines the types, the quantities and the positions of the tower cranes, has a significant impact on the overall productivity and cost-effectiveness of construction projects. The previous research utilized either mathematical methods or visualization tools to find an optimal tower crane layout plan. But such methods and tools are not adequate to evaluate the effect of conflict among tower cranes in terms of time and cost calculations. Moreover, they don’t assure the maximum efficiency of tower crane layout to fulfill the needs of crane-based executed activities. This research develops an Agent-Based Simulation (ABS) model to overcome the limitations of previous research. It calculates the time and the cost of tower cranes operation cycles, taking into account the potential conflict among the working tower cranes. A case study is provided to demonstrate the capabilities and contributions of the developed ABS model.
