=== Produktion von Spielwaren aus Rohstoffen über Zwischenprodukte === | |||
Ein Spielwarenhersteller produziert aus drei Rohstoffen \(R_1, R_2, R_3\) zunächst die beiden Zwischenprodukte \(Z_1, Z_2\), aus denen anschließend die drei Endprodukte \(E_1, E_2, E_3\) gefertigt werden. | |||
Die Pfeile im Gozintographen geben an, wie viele Tonnen eines Materials zur Produktion von 1 Tonne des entstehenden Produkts benötigt werden. | |||
Beispiel: Für die Herstellung von 1 Tonne \(Z_1\) werden 3 Tonnen \(R_1\) und 4 Tonnen \(R_2\) benötigt. | |||

Die Matrix zeigt, wie viele Tonnen der Rohstoffe \(R_1, R_2, R_3\) jeweils zur Herstellung von 1 Tonne der Endprodukte \(E_1, E_2, E_3\) notwendig sind. | |||
Beispielsweise bedeutet die erste Spalte: | |||
Für 1 Tonne \(E_1\) werden benötigt: | |||
* 7 Tonnen \(R_1\) | |||
* 10 Tonnen \(R_2\) | |||
* 3 Tonnen \(R_3\) | |||
Dies ergibt sich daraus, dass die Zwischenprodukte Z1 und Z2 selbst wiederum aus Rohstoffen bestehen. | |||
