Optimization of the COVID-19 Vaccine Distribution Route Using the Vehicle Routing Problem with Time Windows Model and Capacity Constraint

At this time the effectiveness of COVID-19 vaccines has been proven, and it is crucial to carry out complete vaccination population. Therefore, imperative optimize vaccine distribution fleets. This paper discusses optimization routes for Pfizer in Portugal terms transportation time, total costs, CO2 emissions. To end, Vehicle Routing Problem with Time Windows (VRPTW) model a vehicle capacity restriction was used. The VRPTW tested two scenarios. first scenario allowed driver work overtime (585 min). second considered that works 8 h (480 results are presented compare justify proposed method large significance placed safety concerns, economic savings, environmental protection, energy consumption. aims contribute healthcare system by optimizing minimizing process’s carbon footprint.
