with VRP using one 25 cubic yard truck serving all residential locations on a
particular collection day in the 10-hour collection time frame. Once the time
frame limit was reached, the number of residential locations serviced was
determined and then removed from the data-set.
The model was then run again for the remaining residential locations on
that particular collection day. This process was repeated until all locations for
each collection day were serviced, thus providing the total number of 25 cubic
yards trucks needed to service each collection day in the required time frame.
Output from the VRP model for all scenarios includes: driving directions, time
collection begins and ends, total collection time (hours:minutes), total distance
traveled (miles), and number of trips to the transfer station.
Driving directions could greatly benefit solid waste collection companies
by providing drivers with an optimal route serving residential locations that
could reduce miles traveled and fuel consumption.
