Key Points

To develop a computerized optimization model that identifies optimal placement for a group of tower cranes while balancing workloads, avoiding spatial conflicts, and maximizing operational efficiency.
Designed a three-stage framework that first groups tasks and defines feasible crane zones based on geometric proximity.
Adjusted initial task allocations across cranes to smooth individual workloads and minimize crane-to-crane collision conflicts.
Applied a single-crane optimization submodel iteratively to locate precise crane coordinates that minimize total hook transportation time.
Successfully produced coordinated spatial layouts that distributed lifting tasks evenly across multiple simultaneous crane operations.
Achieved reductions in hook travel times and minimized spatial overlap among adjacent cranes during simulated construction operations.
