Vehicle Routing Problem with Time Windows | OR-Tools

Aug 12, 2021· The code creates a dimension for the travel time of the vehicles, similar to the dimensions for travel distance or demands in previous examples. Dimensions keep track of quantities that accumulate over a vehicle's route. In the code above, time_dimension.CumulVar(index) is the cumulative travel time when a vehicle arrives at the location with the given index.
