配一位可轉移助手(3D1H)和三台卡車搭配兩位可轉移助手(3D2H),模型旨在通過將卡
車與可轉移助手合作來平衡工作負荷並提高送貨效率。研究結果證明使用助手來輔助
司機和卡車的優勢,並成功解決了各種情境下的工作負荷平衡問題該應用何種模型。
在測試不同服務區域、長工時工作點比例和卡車及助手數量後,提供了適當的

This study focused on addressing the issue of working hour overload in the logistics
industry during peak periods, such as national holidays or shopping seasons. The proposed models, two drivers with one single helper model (2D1H), three drivers with one helper (3D1H)and three drivers with two helpers (3D2H), aimed to balance the workload and enhance the delivery efficiency by assigning trucks to collaborate with transferable helpers. The study demonstrated the advantages of using helpers to support drivers and trucks and successfully solved the issue of workload balance in every scenario.The study also offered appropriate routing models for different service areas, proportions of long-working-time nodes, and numbers of trucks and helpers. Adjusting the departure and arrival times was identified as an important factor in eliminating idle time and significantly enhancing delivery efficiency. The study implemented Google’s OR-tools and the Hill Climbing Algorithm to optimize the delivery efficiency, balance the workload and obtain feasible solutions for the proposed models of Multiple Transferable Driver Helper Dispatching Problem with Workload Balance (MTDHWB).The findings showed that the determination of which model to use depended on the intended purpose of the logistics or delivery company. The proposed models were optimal choices for balancing workload, and the selection of the appropriate model depended on the service area, proportion of long-working-time nodes, and number of trucks and helpers. Both 2D1H and 3D2H are the most suitable and excellent, while the 3D1H model may be a suitable option when the density is not very high, around 10%. However, further testing is required to obtain more insights on the use of helpers and fleets to support delivery service effectively, efficiently, and equivalently. Overall, this study contributes to the development of efficient and effective logistics and delivery systems.
