Fig. 9(a) shows the travel’s itinerary that should be traversed by
the Delivery Driver. The travel’s planned route is represented by a
blue line, which starts at A, passing through the points B, C and
D, and ending at point E. In the point A, it must be picked up three
loads (codes ‘1’, ‘2’ and ‘3’). These loads must be delivered at the
points B, C and E, respectively. In the point B the load with code
‘1’ should be delivered and the loads ‘4’ and ‘5’ picked up to later
be delivered at the points D and E. In the point C, the delivery of
load ‘2’ is done, and the load ‘6’ is picked up to be delivered at point
E. In the point D, only the load ‘4’ has to be delivered. Finally, at the
point E, the loads ‘3’, ‘5’ and ‘6’ are delivered.
