Reducing the 0-1 knapsack problem with a single continuous variable to the standard 0-1 knapsack problem

Büther, Marcel; Briskorn, Dirk - 2007

The 0-1 knapsack problem with a single continuous variable (KPC) is a natural extension of the binary knapsack problem (KP), where the capacity is not any longer fixed but can be extended which is expressed by a continuous variable. This variable might be unbounded or restricted by a lower or...

Pricing the multiple-choice nested knapsack problem

Drexl, Andreas; Jørnsten, Kurt - 2007

The multiple-choice nested knapsack problem (MCKP) is a generalization of the ordinary knapsack problem, where the set of items is partitioned into classes. The binary choice of selecting an item is replaced by taking exactly one item out of each class of items. Due to the fact that the MCKP is...

Project scheduling with discrete time-resource and resource-resource tradeoffs

Sprecher, Arno; Hartmann, Sönke; Drexl, Andreas - 1994

We consider an extension of the classical resource-constrained project scheduling problem (RCPSP), which covers discrete resource-resource and time-resource tradeoffs. As a result a project scheduler is permitted to identify several alternatives or modes of accomplishment for each activity of...

Optimal industrial classification with heteroskedasticity correction: An application to the Swedish industrial classification system

Chipman, John Somerset; Winker, Peter - 1994

Aggregation may be harmful but cannot always be avoided in the analysis of complex econometric models. It should be carried out intelligently by choosing ein aggregative model optimally for modes of aggregation speeified in advance, i.e. minimizing the bias introduced by aggregation and...

Optimal industrial classification: [an application to the German industrial classification system]

Chipman, John Somerset; Winker, Peter - 1994

A widely used method in the analysis of complex econometric models is to replace the "true model" by an aggregative one in which the variables are grouped and replaced by sums or weighted averages of the variables in each group. The analysis of the problem of choosing an aggregative model...

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...

Rosing, K.E.; ReVelle, C.S. - 1997

In 1997 two papers_new applying the metaheuristics Tabu Search (TS) and Heuristic Concentration (HC) tothe p-median problem were published in consecutive volumes of the European Journal of OperationalResearch. Here we apply the method of HC some of the data sets which were used for...

Communication and punishment in voluntary contribution experiments

Bochet, Olivier; Page, Talbot; Putterman, Louis - 2005

: communication, and punishment (allowing subjects to engage in costly reductions of one another’s earnings after learning of their … contribution decisions). We find that communication increases contributions more than punishment, and, taking into account the cost … of punishment, only communication significantly increases subjects’ earnings and thus efficiency. We study three forms of …
