The demand for subassembly S is 150 units in week 7. Each unit of S requires 1 unit of T and 1 unit of U. Each unit of T requires 1 unit of V, 2 units of W, and 2 units of X. Finally, each unit of U requires 1 unit of Y and 3 units of Z. One firm manufactures all items. It takes 2 weeks to make S, 1 week to make T, 2 weeks to make U, 2 weeks to make V, 3 weeks to make W, 1 week to make X, 2 weeks to make Y, and 1 week to make Z.
Suppose that in addition to 150 units of S, there is also a demand for 30 units of U, which is a component of S. The 30 units of U are needed for maintenance purposes. These units are needed in week 6. Modify the net material requirements plan to reflect this change.
