A new type of model for multi-item capacitated dynamic lotsizing and scheduling
Drexl, Andreas; Haase, Knut - 1992
Three types of multi-item capacitated dynamic lotsizing and scheduling models are well established until now: The … capacitated lotsizing problem, the discrete lotsizing and scheduling problem as well as the continuous setup lotsizing problem. An … lotsizing and scheduling problem. This model type is well suited for incorporating some of the extensions relevant with respect …

Optimization guided lower and upper bounds for the resource investment problem
Drexl, Andreas; Kimms, Alf - 1998
The resource investment problem deals with the issue of providing resources to a project such that a given deadline can be met. The objective is to make the resources available in the cheapest possible way. For each resource, expenses depend on the maximum amount required during the course of...

Sales force deployment by mathematical programming
Haase, Knut - 1999
The sales force deployment problem is considered which arises in many selling organizations. As a solution a novel mixed-integer formulation is introduced which is specifically characterized by an infinite number of variables. A column generation approach is proposed to obtain upper and lower...

Network decomposition-based lower and upper bounds for the discrete time-cost tradeoff problem
Akkan, Can; Drexl, Andreas; Kimms, Alf - 2000
In project management, the project duration can often be compressed by accelerating some of its activities at an additional expense. This is the so-called time-cost tradeoff problem which has been extensively studied in the past. However, the discrete version of the problem which is of great...

Lower bounds for the capacitated facility location problem based on column generation
Klose, Andreas; Drexl, Andreas - 2001
The Capacitated Facility Location Problem (CFLP) is a well-known combinatorial optimization problem with applications in distribution and production planning. A variety of lower bounds based on Lagrangean relaxation and subgradient optimization has been proposed for this problem. However, in...

Duty-period-based network model for airline crew rescheduling
Nissen, Rüdiger; Haase, Knut - 2004
Airline rescheduling is a relatively new field in airline Operations Research but increasing amounts of traffic will make disturbances to the original schedule more frequent and more severe, and thus the need to address the various problems arising from this situation with systematic,...
