link to learn how to do: "to load station set".
If you have more stations than limits of logvrp or limits of user (optional)
The limit of station is 500.
You can read “Dividing
Stations Into Groups Geographically” for more than 500 stations.
2. Create common pick-up/delivery points from stations (optional)

- To: The delivery station should be selected, i.e. if a personnel
should be delivered to workplace, it should be personnel's workplace address. In
other words, it is the destination station for the passenger to be transported.
- Load amount: How many passengers will be transported.

- When "Computation" Tab is selected, under "Constraint" Tab, "Max Number of Routes"
can be set.
- At the end of Optimization "up to maximum number of routes" routes will be created.
- Max Route Duration:
- When "Computation" Tab is selected, under "Constraint" Tab, "Max Route Duration"
can be set. (d:h:m)
- At the end of the optimization, the duration of a route will no more than the specified
time.
- If you don't want to enter any information, "0:0:0" must be determined.

can be set.
- At the end of the optimization, bir rotada en fazla o kadar noktaya uğranacak şekilde
sonuçlar çıkacaktır.
- Max Distance Per Route:
- When "Computation" Tab is selected, under "Constraint" Tab, "Max Distance Per Route"
can be set.
