Note: Optimal base-stock policy for the inventory system with periodic review, backorders and sequential lead times
Johansen, Søren Glud; Thorstenson, Anders - Ehrvervøkonomisk Institut, Institut for Økonomi - 2005
We show that well-known textbook formulae for determining the optimal base stock of the inventory system with continuous review and constant lead time can easily be extended to the case with periodic review and stochastic, sequential lead times. The provided performance measures and conditions...

A comparison between the order and the volume fill rates for a base-stock inventory control system under a compound renewal demand process
Larsen, Christian; Thorstenson, Anders - Ehrvervøkonomisk Institut, Institut for Økonomi - 2006
The order fill rate is less commonly used than the volume fill rate (most often just denoted fill rate) as a … total quantities, the order fill rate should be the preferred measure.

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.
