Abstract

Port operational efficiency and energy consumption are pivotal, but sometimes contradictory factors influencing its competitiveness. In light of this, the simultaneous optimization of these two objectives within the port integrated scheduling of quay cranes, internal vehicles, and yard cranes, can aid in sustaining port development in the era of digitalization and autonomy. Furthermore, given the persistent fluctuations in uncertain operation time of the cranes and vehicles in port, it becomes imperative to consider the robustness of their scheduling plans collectively. This paper therefore aims to develop a new tri-objective mixed-integer programming model for the first time that enables the incorporation of operational uncertainty and energy efficiency into the context of port operation scheduling consideration. The three objectives are makespan, energy consumption, and scheduling plan robustness, which is represented by anti- cascade and robustness evaluation indices. To effectively address complex optimization challenges, a novel multi-objective solution algorithm has been developed, featured with a dynamic f itness evaluation method selection mechanism. This mechanism utilizes a new crowding distance operator based on the cosine distance of objective value vectors to enhance population diversity in the early stages of the algorithm’s iterations. At the later stages, it employs a fuzzy correlation entropy operator to ensure rapid convergence and high-quality solutions. Comparative experiments conducted in scenarios involving emerging technologies such as U-shaped ports and double-cycling operational mode demonstrate the evident improvements achieved by the new model in terms of makespan, energy consumption, and computational efficiency. Based on the compelling experimental results, meaningful insights and implications are put forward, including the potential time and energy savings in port operations, and the practical applicability of these models and algorithms in both port and various other industries.
