EcoFleet Logistics has enlisted you, a logistics optimization expert, to develop a strategy that minimizes

the total travel time for their EV fleet between the depot and the retail stores. This task is crucial

charging stations at various locations have charging rates that degrade over time due to technological

limitations of both the battery and the station. This degradation can be calculated using the formula
