This paper describes strip sequencing models for large scale traveling salesman problems arising in flexible manufacturing operations in two or three discre...
BibTeX referenceA New Branching Strategy for Time Constrained Routing Problems with Application to Backhauling
In this paper we explore a new branching strategy for branch-and-bound approaches based on column generation for the vehicle routing problems with time wind...
