<h2>Produktionsprozess eines Spielwarenherstellers</h2> | |||
<p>Ein Spielwarenhersteller stellt in einem zweistufigen Produktionsprozess aus drei Rohstoffen R1, R2, R3 drei Endprodukte E1, E2, E3 her. Dabei werden zunächst Zwischenprodukte Z1, Z2 hergestellt, welche dann weiter zur Herstellung der Endprodukte verarbeitet werden.</p> | |||

<h3>Materialbedarfsmatrix</h3> | |||
<p>Die Materialbedarfsmatrix RZ (Rohstoffe zu Zwischenprodukten) ist gegeben durch:</p> | |||
<p> | |||
RZ = | |||
\(\begin{pmatrix} | |||
3 & 2 \\ | |||
4 & 1 \\ | |||
0 & 2 | |||
\end{pmatrix}\) | |||
</p> | |||
<p>Die Materialbedarfsmatrix ZE (Zwischenprodukte zu Endprodukten) ist gegeben durch:</p> | |||
<p> | |||
ZE = | |||
\(\begin{pmatrix} | |||
2 & 1 & 0 \\ | |||
1 & 2 & 3 | |||
\end{pmatrix}\) | |||
</p> | |||
<h3>Gesamtmaterialbedarf</h3> | |||
<p>Der Gesamtmaterialbedarf RE (Rohstoffe zu Endprodukten) ergibt sich aus der Matrixmultiplikation:</p> | |||
<p> | |||
RE = RZ × ZE = | |||
\(\begin{pmatrix} | |||
3 & 2 \\ | |||
4 & 1 \\ | |||
0 & 2 | |||
\end{pmatrix} | |||
× | |||
\begin{pmatrix} | |||
2 & 1 & 0 \\ | |||
1 & 2 & 3 | |||
\end{pmatrix} | |||
= | |||
\begin{pmatrix} | |||
8 & 7 & 6 \\ | |||
9 & 6 & 3 \\ | |||
2 & 4 & 6 | |||
\end{pmatrix}\) | |||
</p> | |||
<p><strong>Interpretation:</strong> Die Matrix RE zeigt den Gesamtbedarf an Rohstoffen für die Herstellung einer Tonne jedes Endprodukts. Beispielsweise werden für eine Tonne E1 insgesamt 8 Tonnen R1, 9 Tonnen R2 und 2 Tonnen R3 benötigt.</p> | |||
