The increase of resource (energy and material) efficiency by eliminating unnecessary consumption represents the logical continuation from lean manufacturing to lean and green manufacturing. However, economic efficiency remains the primary decision criterion for the implementation of corresponding strategies. This paper presents a simulation based approach for monetary assessment of lean and green manufacturing systems considering non-monetary green limits. Inclusion of material and energy consumption as well as resulting greenhouse gas emissions enables planners to predict the overall economic performance of a factory. Furthermore, product variant specific footprints of material and energy demands as well as resulting emissions support in-depth analysis of value streams in manufacturing.

Neben den klassischen Zielgrößen Kosten, Zeit und Qualität sind Unternehmen zunehmend mit Forderungen nach Ressourceneffizienz (Energie, Material) und Verringerung von CO2-Emissionen konfrontiert. In aller Regel stellt die Wirtschaftlichkeit jedoch weiterhin das entscheidende Kriterium bei der Einführung „grüner“ Maßnahmen dar. Der Fachbeitrag beschreibt eine Methodik zur Planung und Bewertung von Maßnahmen zur wirtschaftlichen Gestaltung von Produktionssystemen unter Berücksichtigung „grüner“ Grenzwerte.   Resource efficiency and reduction of carbon dioxide emissions gain increasing importance for manufacturing companies alongside the common target dimensions cost, time and quality. Nevertheless, economic efficiency remains the primary decision criterion for the implementation of „green“ strategies. This approach presents a methodology for planning and assessment of strategies for the economic configuration of manufacturing systems with regard to „green“ limits.
