Anwendung monetärer und nicht-monetärer Entscheidungsinstrumente am Beispiel von Investitionsentscheidungen der MAN Nutzfahrzeuge AG

Bergheim, Kirtan, Gerbaulet, Clemens, Graßhoff, Nico, Kittlaus, Barnabas, Klapper, Helge, Plischtil, Max, Rehm, Franziska, Scheel, Ramona, Kirsch, Arne 11 October 2011 (has links) (PDF)
In der vorliegenden Arbeit wird der Beschaffungsprozess der MAN Nutzfahrzeuge AG analysiert. Zu diesem Zweck werden drei verschiedene Methoden angewendet. Das Ziel besteht darin herauszufinden, inwieweit die Berücksichtigung ökologischer Aspekte den Entscheidungsprozess beeinflusst, sodass nachhaltige Beschaffung eine sinnvolle Option bieten kann. Dazu werden verschiedene Beschaffungsalternativen unter Verwendung der Ansätze zur Lebenszykluskostenrechnung, Ökobilanzierung und Hemmnisanalyse verglichen. Ziel ist es, Empfehlungen für zukünftige Investitionsentscheidungen abzuleiten. Die vorliegende Ausarbeitung zeigt, dass die Ausweitung der Investitionsbetrachtung auf den gesamten Lebenszyklus weit über konventionelle Ansätze hinaus gehen.

Application of a GIS Multi-Criteria Decision Analysis for the Identification of Intrinsic Suitable Sites in Costa Rica for the Application of Managed Aquifer Recharge (MAR) through Spreading Methods.

Bonilla Valverde, José Pablo, Blank , Clemens, Roidt, Mario, Schneider, Lisa, Catalin, Stefan 27 March 2017 (has links) (PDF)
Costa Rica’s annual mean precipitation is above 3300 mm, but this precipitation is not evenly distributed in time or space, producing clear differentiated wet and dry seasons in most of the country. Droughts are also common phenomena which greatly affect the availability of water resources. Managed aquifer recharge (MAR) schemes are being taken into consideration to enhance the underground water storage capacity of the country. The present study constitutes the first assessment for the identification of suitable sites for the implementation of MAR technology spreading methods (SM) in Costa Rica. The suitable sites are identified by means of a geographic information system multi-criteria decision analysis (GIS-MCDA) based on four criteria: hydrogeological aptitude, terrain slope, top soil texture and drainage network density. Four steps are performed in order to identify these sites: problem definition, screening for suitable areas, suitability mapping, and sensitivity analysis. The suitability map was divided in two zones after the screening: suitable and unsuitable, the first zone was further divided in five classes according to the weighted linear combination (WLC) ranking. The results indicate that 61% of the country is suitable for conducting SM. This map is a tool for future implementation of MAR techniques in the country.
