Abstract

This study aims to identify the non-value-adding activities during vehicle stowage operations in automobile terminals and propose a connected automated vehicle (CAV) loading system, a self-driving-car-loading system. Furthermore, the productivity of the CAV loading system is compared with the current loading system. A simulation model of an actual loading system was developed using the software FlexSim. The simulation results showed that the walking time of workers, operation time of shuttle vans, and waiting time occupied a large part of the cycle time in the current operation system. The proposed CAV loading system has eliminated these inefficiencies, and increased productivity by 26.78%. This is the first study to (1) present a self-driving-car-loading system in a simulated automobile terminal of a real-world size, and (2) propose a CAV loading system. Results provide useful insights for the integration of self-driving technology into future automobile port operations.

连接和自动车辆装载系统，用于改善人类驾驶车辆在滚装/滚装港口操作中的操作效率低下

本研究旨在识别汽车码头车辆积载作业中的非增值活动，并提出一种连接自动车辆(CAV)装载系统，即自动驾驶汽车装载系统。此外，还将CAV加载系统的生产率与现有加载系统进行了比较。利用FlexSim软件建立了实际加载系统的仿真模型。仿真结果表明，在当前的运行系统中，工人的步行时间、穿梭车的运行时间和等待时间占据了很大一部分周期时间。提出的CAV装载系统消除了这些低效率，并将生产率提高了26.78%。这是第一个(1)在现实世界规模的模拟汽车终端中展示自动驾驶汽车装载系统的研究，(2)提出CAV装载系统。研究结果为将自动驾驶技术整合到未来的汽车港口运营中提供了有用的见解。

期刊介绍： Transportation Planning and Technology places considerable emphasis on the interface between transportation planning and technology, economics, land use planning and policy. The Editor welcomes submissions covering, but not limited to, topics such as: • transport demand • land use forecasting • economic evaluation and its relationship to policy in both developed and developing countries • conventional and possibly unconventional future systems technology • urban and interurban transport terminals and interchanges • environmental aspects associated with transport (particularly those relating to climate change resilience and adaptation). The journal also welcomes technical papers of a more narrow focus as well as in-depth state-of-the-art papers. State-of-the-art papers should address transport topics that have a strong empirical base and contain explanatory research results that fit well with the core aims and scope of the journal.
