In this paper we consider the problem of allocating scarce resources in a divisionalized company; the resources are made available by the headquarters and requested by profit centers (PCs). This problem was observed at a large german insurance company (LAGIC). Currently, the resources are...

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,...

The "Capacitated lot sizing problem with setup carry-over" is based ort the well known "Capacitated lot sizing problem" and incorporates the possibility of preserving a setup-state from a period to the following. Sox and Gao [2] decompose their formulation of the first one (GCLP1) by Lagrangian...

This paper surveys a large variety of mathematical models and up-to-date solution techniques developed for solving a general flight gate scheduling problem that deals with assigning different aircraft activities (arrival, departure and intermediate parking) to distinct aircraft stands or gates....

This paper addresses the robust spanning tree problem with interval data, i.e. the case of classical minimum spanning tree problem when edge weights are not fixed but take their values from some intervals associated with edges. The problem consists in finding a spanning tree that minimizes...

Manpower still is one of the most expansive resources, in spite of increasing automation. While employee scheduling and rostering has been the topic of extensive research over the past decades, usually it is assumed that the demand for staff is either given or can be obtained without difficulty....

Effectiveness in the use of the work force is often the crucial advantage in a company's long-term success over its competitors, especially in technology driven and highly competitive branches as the one considered in this article. While employee scheduling and rostering has been the topic of...

Wir betrachten sog. Transferable-Put-Rights (TPRs), die im Rahmen eines Aktienrückkaufs per Tender-Offer den Aktionären gewährt werden können und als das spiegelbildliche Äquivalent zu den in Deutschland traditionell bei Kapitalerhöhungen ausgegebenen Bezugsrechten anzusehen sind....

This paper addresses the airport flight gate assignment problem with multiple objectives. The objectives are to maximize the total flight gate preferences, to minimize the number of towing activities and to minimize the absolute deviation of the new gate assignment from a so-called reference...
