Distortions in a multi-level co-financing system: the case of the agri-environmental programme of Saxony-Anhalt

Kirschke, Dieter; Häger, Astrid; Jechlitschka, Kurt; … - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 56 (2007) 7, pp. 297-304

In this paper we analyse the impact of the EU multi-level co-financing system on regional policy-making and priority setting taking the case of the agri-environmental programme of Saxony-Anhalt. The implications of several co-financing scenarios are analysed and compared to respective lump-sum...

Optimierung unter Unsicherheit mit Hilfe stochastischer Simulation und Genetischer Algorithmen - dargestellt anhand der Optimierung des Produktionsprogramms eines Brandenburger Marktfruchtbetriebes -

Mußhoff, Oliver; Hirschauer, Norbert - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 53 (2004) 7, pp. 264-279

Optimization has been recognized as a powerful tool in teaching and research for a long time. In spite of its well known problem solving capacity, some methodological obstacles have persisted over the years. The main problem is that stochastic variables and their correlations cannot be...

Interaktive Programmierungsansätze für die Gestaltung von Agrar- und Umweltprogrammen

Kirschke, Dieter; Jechlitschka, Kurt - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 52 (2003) 4, pp. 211-217

Planning agricultural and environmental programmes has become a complex task. In this paper we show how interactive programming can help to solve such complex policy decision-making problems. The basic linear programming model is implemented with Excel. We show, for a hypothetical agricultural...

Beurteilung von Agrarumweltprogrammen: Eine einzelbetriebliche Analyse in Baden-Württemberg und Nordbrandenburg

Baudoux, Patrick - In: Agrarwirtschaft: Zeitschrift für Betriebswirtschaft, … 50 (2001) 4, pp. 249-261

Under the condition of significant changes in the framework of EU Agricultural Policy Agro-Environmental Programmes are evaluated in this paper. The MEKA-Programme of Baden-Württemberg and the KULAP-Programme of Brandenburg, both measures under the EU-Regulation VO (EWG) 2078/92 of 1992, are...

Effects of national energy policies on carbon dioxide emissions in a European internal electricity market: Results from a simulation model of the European power systems

Hoster, Frank - 1997

This article considers the economic and environmental (in terms of CO2) effects of national energy policies in a European Single Market for electricity. It was found that the combined CO2/Energy-tax proposed by the European Commission would be able to stabilise the current volume of...

A comparison of logic and mixed-integer programming solvers for batch sequencing with sequence-dependent setups

Jordan, Carsten; Drexl, Andreas - 1993

A batch sequencing model with sequence-dependent setup-times and -costs is used to compare modelling and solving with two different general solvers. "Conceptual models" are implemented in the constraint propagation / logic programming language CHARME and solved with the PROLOG inference engine....

Academic course scheduling under workload and changeover constraints

Drexl, Andreas; Juretzka, Jan; Salewski, Frank - 1993

Two phases can be distinguished in academic course scheduling: In phase one lectures have to be assigned to professors, whereas in phase two the lectures have to be scheduled. Here we assume that the lectures are already assigned to professors, i.e. the first phase has been done. For the second...

A note on "hierarchical models for multi-project planning and scheduling"

Hartmann, Sönke; Sprecher, Arno - 1993

We consider the multi-mode resource-constrained project scheduling problem. The focus is on an algorithm which is … supposed to find a makespan optimal solution. This algorithm has been presented in a recent paper by Speranza and Vercellis …. The correctness of the algorithm is examined. Moreover, two counterexamples in which the algorithm does not lead to an …

Demand shuffle - a novel method for multi-level proportional lot sizing and scheduling

Kimms, Alf - 1994

This contribution acquaints the reader with a model for multi-level single-machine proportional lot sizing and scheduling problems (PLSPs) that appear in the scope of short-term production planning. It is one of the first papers that deals with dynamic capacitated multi-level lot sizing and...
