The effect on a handshake operation between twin overhead shuttle cranes under demand uncertainty

We propose a scenario-based handshake location determination (SHLD) model that balances the average workload of twin overhead shuttle cranes (OSs) sharing a single rail in a rail-based container terminal (RACT). The handshake operation is necessary to decrease the side effect of interference between the twin OSs as they store and transfer containers between locations. We design computational experiments considering demand uncertainty over the available scenarios in a decision-making period. The results show that the SHLD optimizes the workload balance of twin OSs in multiple scenarios under demand uncertainty. We use the simulation for validation and evaluation of the proposed model. The simulation results show that the SHLD guarantee the workload balance of twin OSs and reduce the waiting time of vehicles significantly.
