The demand for subassembly S is

90

units in week 7. Each unit of S requires

1

unit

of T and

2

units

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

90

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. Additionally, a new order has been received for

90

units of S due in week 8. Modify the net material requirements plan to reflect these changes.
