The integrated allocation and scheduling of handling resources are crucial problems in the railway container terminal (RCT). We investigate the integrated optimization problem for handling resources of the crane area, dual-gantry crane (GC), and internal trucks (ITs). A creative handling scheme is proposed to reduce the long-distance, full-loaded movement of GCs by making use of the advantages of ITs. Based on this scheme, we propose a flexible crossing crane area to balance the workload of dual-GC. Decomposing the integrated problem into four sub-problems, a multi-objective mixed-integer programming model (MIP) is developed. By analyzing the characteristic of the integrated problem, a three-layer hybrid heuristic algorithm (TLHHA) incorporating heuristic rule (HR), elite co-evolution genetic algorithm (ECEGA), greedy rule (GR), and simulated annealing (SA) is designed for solving the problem. Numerical experiments were conducted to verify the effectiveness of the proposed model and algorithm. The results show that the proposed algorithm has excellent searching ability, and the simultaneous optimization scheme could ensure the requirements for efficiency, effectiveness, and energy-saving, as well as the balance rate of dual-GC.

Improving operational efficiency and reducing energy consumption are common objectives for all ports.In previous research by authors, a new high operation platform mode was proposed. It had been proven to reduce energy consumption and be economically feasible. On this basis, this paper studied the influence of high operation platform mode on automated container terminal (ACT) efficiency. This paper took U-shaped ACT as the research object, put forward the operation characteristics of U-shaped ACT under high operation platform mode, and constructed the operation time model of high and low operation platform mode respectively. This paper took 30 containers at the same bay as an example to calculate and verify. The computational results shows that when 𝑉 𝑣 1 /𝑉 ℎ 1 is above the 𝑉 𝑣 1 /𝑉 ℎ 1 − 𝛼 curve, the operation time of high platform mode is shorter, and the operation efficiency of ACT is higher (𝑉 𝑣 1 represents the speed of spreader with container vertically moving; 𝑉 ℎ 1 represents the speed of spreader with container horizontally moving.); when 𝑉 𝑣 1 /𝑉 ℎ 1 is under the 𝑉 𝑣 1 /𝑉 ℎ 1 − 𝛼 curve, the shortening time of quay cranes operation is greater than the increasing time of yard cranes operation, so the overall operational efficiency of ACT is still improved. Therefore, high operation platform mode can improve efficiency of ACT.

Automatic guided vehicles (AGVs) in the horizontal area play a crucial role in determining the operational efficiency of automated container terminals (ACTs). To improve the operational efficiency of an ACT, it is essential to decrease the impact of battery capacity limitations on AGV scheduling. To address this problem, this paper introduces battery swapping and opportunity charging modes into the AGV system and proposes a new AGV scheduling problem considering the hybrid mode. Firstly, this study describes the AGV scheduling problem of the automated container terminals considering both loading and unloading tasks under the hybrid mode of battery swapping and charging. Thereafter, a mixed-integer programming model is established to minimize the sum of energy costs and delay costs. Secondly, an effective adaptive large neighborhood search algorithm is proposed to solve the problem, in which the initial solution construction, destroy operators, and repair operators are designed according to the hybrid mode. Finally, numerical experiments are conducted to analyze the effectiveness of the model and the optimization performance of the algorithm. The results demonstrate that the hybrid mode of battery swapping and charging can effectively reduce the number of battery swapping times and scheduling costs compared to the existing mode.
