| Tiivistelmä: | The Capacitated Vehicle Routing Problem on Trees /CVRPT/ consists of determining vehicle collection routes starting and ending at the depot so that: the weight associated with any given vertex is collected by exactly one vehicle; the sum of all weights collected by a vehicle does not exceed its capacity; a linear combination of the number of vehicles and of the total distances travelled by these vehicles are minimized. A good lower bound for the problem was derived by generalizing the Martello and Toth bin packing bound. A linear upper bounding procedure that generally produces solution values within 5 p.c. of the optimum was also developed. |
