Abstract: Rail mounted gantry cranes (RMGCs)are the key resources of railway container terminals.The han-dling strategy of RMGCs significantly impacts the operation efficiency and service quality of railway container terminals.In this paper,to deal with the RMGC scheduling optimization problem of railway container termi-nals,the RMGC scheduling optimization model was established to determine the optimal loading-unloading se-quence and to ensure loading-unloading operations to be implemented within the least possible period of time. The hybrid particle swarm optimization algorithm was designed to solve the model.Verification was made by numerical examples.The research results show that the proposed algorithm is effective to shorten the RMGC loading-unloading time and idle running time.
