A Refined Collaborative Scheduling Method for Multi-Equipment at U-Shaped Automated Container Terminals Based on Rail Crane Process Optimization

A U-shaped automated container terminal (ACT) has been proposed for the first time globally and adopted to construct Beibu Gulf Port ACT. In this ACT layout, double cantilevered rail crane (DCRC) simultaneously provides loading unloading services external trucks (ECTs) automatic guided vehicles (AGVs) entering yard. The DCRC a complex scheduling coupling relationship with AGV ECT, its mathematical model is extremely complex. There an urgent need study practical collaborative optimization algorithm DCRC, AGV, ECT. paper, we optimize process flow of DCRCs refined DCRCs, AGVs ECTs in ACTs. Firstly, analyze operation divide 16 conditions into four modes optimization. Secondly, different variables parameters are set DCRC’s operating modes, dispatching proposed. Finally, adaptive co-evolutionary genetic solves model. Meanwhile, arithmetic examples verify correctness practicality algorithm. experimental results show that total running shortest when number quay cranes (QC) ratios 1:2 1:10, respectively. At same time, QCs more significant impact on efficiency than AGVs, priority should be given allocation DCRCs. research have essential guidance value ACTs under construction enrich theory method equipment.
