The demand for subassembly S is 100 units in week 7. Each unit of S requires

2

units

of T and

2

units

of U. Each unit of T requires

2

units

of V,

1

unit

of W, and

2

units

of X. Finally, each unit of U requires

2

units

of Y and

3

units of Z. One firm manufactures all items. It takes 2 weeks to make S,

2

weeks

to make T, 2 weeks to make U,

1

week

to make V,
