Evaluation of a Team-Based Collection and Delivery Operation

The rise in the volume of e-commerce is adding increasing pressure on logistics parcel delivery. To improve efficiency their operations, industry Japan exploring team-based collection and delivery (TCD), whereby sales driver (SD) hands out parcels to field crews (FC), who subsequently deliver them door. However, TCD still understudied. This study proposes a method for optimizing route evaluates ongoing operation. problem focuses minimizing task completion time using parameters derived through surveys actual operations. Comparison between seven different methods show that newly proposed fuzzy c-means clustering with genetic algorithm outperforms rest, rapidly computing sufficiently accurate results. Results suggest optimal reduces total by up 18.7%. amount saved varies considerably area number delivered. Additional constraints improving safety, cost-benefit FCs, impact environmental cost are also considered. helps spread workload travel FCs more evenly, thus further reducing time.
