Abstract
A mixed integer linear programming model to support strategic decision making is presented, in order to find the optimal processing structure for a slaughter byproduct business. In an integrated approach environmental objectives (such as odour emission, water pollution and energy consumption), market outlets, quality requirements (both for product and process), costs of processing, transportation, environmental measures and governmental restrictions are modelled to find the optimal investment strategy for future ways of processing slaughter by-products. Emphasis has not been put on development of new models or techniques. The value of this contribution is how to find new cost-effective logistical solutions within a framework of environmental restrictions, quality and technological opportunities.
Zusammenfassung
In diesem Beitrag wird ein gemischt ganzzahlig lineares Optimierungsmodell vorgestellt, um eine bestmögliche Verarbeitung und Vermarktung von Nebenprodukten der Schlachtung zu ermöglichen. In einem integrierten Modell werden umweltpolitische Aspekte (wie Geruchsemission, Wasserverunreinigung und Energieverbrauch), Absatzmöglichkeiten, Qualitätsaspekte (dies gilt sowohl für die Endprodukte als auch für den Herstellungsprozeß), Kosten, Infrastruktur, umweltpolitische Auflagen und gesetzliche Vorschriften berücksichtigt, um optimale zukunftstragende Investitionen für die Verarbeitung von Nebenprodukten der Schlachtung zu finden. Der Schwerpunkt lag dabei nicht in der Entwicklung von neuen Modellen oder Methoden, sondern im Erkennen von neuen kostengünstigen logistischen Lösungen in einem Zusammenspiel von Umweltauflagen, Qualität und technologischen Chancen.
