Ziel dieser Magisterarbeit ist es, ein Programm zu entwickeln, welches die mittels DEA generierte Effizienzhuelle fuer eine gegebene Datenmenge in einem 3D Diagramm inklusive der schwach effizienten Abschnitte darstellen kann. Geometrisch gesehen wird eine konvexe Huelle ueber alle beobachteten DMUs gespannt. Fuer den zweidimensionalen (2D) Fall, also den Fall eines Inputs und eines Outputs, gibt es viele Darstellungsmoeglichkeiten, fuer die mittels DEA konstruierte Effizienzhuelle. Um diese Uberlegungen graphisch darstellen zu koennen, werden in einem Diagramm die Effizienzhuelle und die ineffizienten DMUs dargestellt. Im dreidimensionalen (3D) Fall, also im Fall eines Inputfaktors und zweier Outputfaktoren oder zweier Inputfaktoren und eines Outputfaktors, besteht die Effizienzhuelle aus einer konvexen 3D Flaeche, einem sogenannten Produktionsgebirge. Die Grundidee der DEA (Data Envelopment Analysis) ist es, die Input- und Outputfaktoren der jeweiligen DMUs (Decision making unit) so zu gewichten, dass die Produktivitaet der jeweils betrachteten DMUs maximiert wird und in Relation zur Produktivitaet aller anderen DMUs gesetzt wird.
