The integrated scheduling of quay cranes, internal vehicles, and yard cranes in container terminals aims to improve port operations often requires robustness under uncertainty with cascade effects. In terminal operations, equipment operating time poses challenges effective scheduling, as even small fluctuations can create effects throughout the rendering original schedule ineffective. This research develop a new method that enables balance between optimization scheduling. Additionally, double-cycling operation mode U-shaped layout, known for their improved efficiency terminals, are gaining increasing attention hence incorporated into this study. It creates three-stage hybrid flow shop problem bi-directional flows, waiting time, uncertain time. To address complex problem, mixed integer programming model is proposed characterize an index based on network structure entropy designed evaluate anti-cascade effect well schedule. makespan serve bi-objectives, transforming bi-objective one. non-dominated sorting genetic algorithm-Ⅱ appropriate coding decoding rules utilized solve obtain set Pareto frontier solutions. feasibility verified through real case analysis.
