Exercise 8: Finding best routes to service paired orders
In this exercise, your goal is to find the best routes for a fleet of vans to
transport people who would otherwise not have access to transportation
from their homes to different hospitals for medical appointments. You will
accomplish this by solving a vehicle routing problem (VRP) analysis using
order pairs, which relate and sequence two orders (stops) so that the vans
will pick up riders and take them to their proper destinations. Using other
features of the VRP analysis layer, you'll also make sure that additional
requirements are met. For instance, you will enter a max transit time for
order pairs so that riders don't spend too much time in transit. You'll use time windows on orders so that riders
are not late for their appointments. Some riders require wheelchairs; you'll use specialties to match those
riders with vans that have wheelchair lifts. Once the routes are determined, you will generate turn-by-turn
directions of the resulting routes, which can be electronically distributed or printed and given to the drivers.
