Horizontal operations scheduling optimization for automated lifting vehicles at automated container terminal
For the coordination scheduling optimization problems between automated lifting vehicles(ALV) and quayside container cranes, based on loading and unloading operation mode and considering the time series constraint when ALV handling events happened and the time windows constraint of quay handling events, a bi-objective mathematical formulation was proposed in view of the dual cycle-loading/unloading simultaneously in quayside operation. The operation sequences of ALVs were optimized, the compared results of the optimized as well as the time costs under different constraints were gained and the optimized practicality was proved. Four experiment scenarios were performed to further analyze those above-mentioned results. Effects of parameter changes and the model features were analyzed by adjusting parameters. Comparison results show that the ALV total time costs increase with the amount of container handling task and the length of ALV preparation time, while reduce with the time windows increasing. The faster the speed of ALVs is, the more adaptations of time windows changes it gets.
