Optimizing delivery efficiency through vehicle modifications: a comparative analysis of standard and side-door trucks in capacitated vehicle routing with time windows

This research explores how vehicle modifications, specifically adding side doors to trucks, impact delivery efficiency in the Capacitated Vehicle Routing Problem with Time Windows (CVRPTW). By using a simulation-based approach, the study compares standard trucks with modified trucks across a case involving 15 customers, one depot, and a fleet of 5 trucks. The findings show that side doors significantly reduce service times per pallet, leading to shorter route times and improved operational efficiency. A cost-benefit analysis confirms the economic feasibility of these modifications by calculating a payback period. This research offers valuable insights into enhancing delivery operations through vehicle modifications.
