The yard operation efficiency is an important index reflecting the sea-side loading and unloading capacity of automated container terminal and the level of receiving and dispatching containers on the land-side.Aiming at the unreasonable and low efficiency problems of yard scheduling condition that occur during the yard operation of automated container terminal,we carry out the research on yard scheduling rule.By analyzing the actual operational requirements of each working condition in the yard,we establish the scheduling principles for sea-side and land-side operations in the yard,optimize the scheduling sequence for different working conditions,and increase the ratio of re-entry and re-exit of automated yard operations to improve the logic of scheduling in the yard of the automated terminal.Then we compare yard operation efficiencies before and after the optimization of the scheduling rules.The results show that the optimized yard scheduling rules can significantly improve the efficiency of automated terminal yard operation and external service level,and improve the core competitiveness of automated terminals.
