We consider the train delivery problem which is a generalization of the bin packing problem and is equivalent to a one dimensional version of the vehicle routing problem with unsplittable demands. The train delivery problem is strongly NP-Hard and does not admit an approximation ratio

This paper addresses the problem of finding the minimum number of vehicles required to visit a set of nodes subject to time window constraints. A secondary objective is to minimize the total distance traveled. Each node requires a predetermined amount of service in the form of pickups and deliveries.

(1993) Dual bin packing with items of … Two are based on bin packing structures generated by the capac-ity or time window constraints. The other is derived from the associated graph created by pairs of customers having incompatible demands or time windows. A guided local search algorithm for the VRPTW was introduced by Kilby et al. (1998). In guided local search, the objective function is augmented with a penalty term reﬂecting

One-Dimensional Bin Packing IIMA. the bin packing problem can be formulated as a minimum ﬂow between vertex 0 and vertex c with constraints enforcing that the number of edges of a given length used by the ﬂow must be greater than or equal to the number of items of the corresponding size. variables x ij are associated with the edges (i;j). x c0 denotes the ﬂow variable corresponding to the number of bins used. we will, approximation algorithms for distance constrained vehicle routing problems viswanath nagarajan⁄ r. raviy abstract we study the distance constrained vehicle routing …); routing instance, there is a corresponding bin-packing instance.3 thus we can say that vrp-this di cult combinatorial problem- conceptually lies at the intersection of these two well-studied problems:, the train delivery problem - vehicle routing meets bin packing aparna das yclaire mathieu shay mozes abstract we consider the train delivery problem which is a generalization of the bin packing.
