Solving the Capacitated Arc Routing Problem with Time Windows using Column Generation

Johnson, Ellis L.; Wøhlk, Sanne - Ehrvervøkonomisk Institut, Institut for Økonomi - 2009

In this paper we consider the Capacitated Arc Routing Problem with Time windows. We suggest two algorithms for solving the problem to optimality and a heuristic for obtaining high quality solutions. To our knowledge this is the first paper to consider optimal solution of that problem.

Managing multi‐item common vendor inventory system with random demands

Kumar, Sameer; Chandra, Charu - In: International Journal of Physical Distribution & … 32 (2002) 3, pp. 188-202

This paper deals with developing new heuristic ordering rules for managing multi‐item, single vendor inventory systems with random demands. The inventory position for each item is continuously reviewed, and an order is placed when the projected stockout cost for all items exceeds a certain...
