We assume that One end item needs 2 units L, 1 unit C and 3 units K. One unit L needs 2 units B and 3 units J. One unit C needs 2 units G and 2 units B. One unit K needs 4 units H and 2 units B. Two orders of 40 units and 60 units will be sent at the week 8 and 9. The manager knows that 15 units of B are scheduled to arrive at the

beginning of week 4. Only the component B should be ordered by lot and the lot size is 30. Use tables to make MRPs for end products and components.

\begin{tabular}{|c|c|c|} \hline Item & Lead time & Amount on hand \\ \hline End item & 1 & \\ \hline L & 2 & 10 \\ \hline C & 3 & 15 \\ \hline K & 3 & 20 \\ \hline B & 2 & 30 \\ \hline J & 3 & 30 \\ \hlineG & 3 & 5 \\ \hlineH & 2 & \\ \hline \end{tabular}
