Multiobjective Optimization for Autonomous Straddle Carrier Scheduling at Automated Container Terminals

---

A multiobjective optimization model is presented in this paper for the Autonomous Straddle Carriers Scheduling (ASCS) problem in automated container terminals, which is more practical than the single objective model. The model considers three objectives [i.e., Straddle Carriers (SCs) traveling time, SC
waiting time and finishing time of high-priority container-transferring jobs], and their weighted sum is investigated as the representative example. The presented model is formulated as a pickup and delivery problem with time windows in the form of binary integer programming. An exact algorithm based on
Branch-and-Bound with Column Generation (BBCG) is employed for solving the multiobjective ASCS problem. Based on the map of an actual fully automated container terminal, simulation results are compared with the single-objective scheduling to demonstrate the effectiveness and flexibility of the presented multiobjective model, as well as the efficacy of the BBCG algorithm for autonomous SC scheduling.
Note to Practitioners—Effective operation of straddle carriers is very important for container terminal managers to increase the productivity and reduce the operational cost of container transportation
at automated terminals. This study develops a multiobjective model and an exact algorithm for the task allocation of container transportation using autonomous straddle carriers. Based on different optimization requirements, the optimal schedule and cost obtained by the presented multiobjective model and the exact algorithm can help the terminal operators to evaluate the performance of the operation of straddle carriers in terms of container transportation. The study can also provide an effective and flexible operational scheme for terminal managers.
