K The demand for subassembly S is 130 units in week 7. Each unit of S requires 1 unit of T and 2 units of U. Each unit of T requires 2 units of V, 1 unit of W, and 1 unit 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. Click the icon to view the product structure and the time-phased product structure. Click the icon to view the on-hand inventory. Suppose that in addition to 130 units of S, there is also a demand for 20 units of U, which is a component of S. The 20 units of U are needed for maintenance purposes. These units are needed in week 6. Additionally, a new order has been received for 80 units of S due in week 8. Modify the net material requirements plan to reflect these changes.
