Prepare a master schedule like that shown in Figure given this information: The forecast for each week of an eight- week schedule is 50 units. The MPS rule is to schedule production if the projected on- hand inventory would be negative without it. Customer orders (committed) are as follows:

Week Customer Orders

1 .........52

2 .........35

3 .........20

4 .........12

Use a production lot size of 75 units and no beginning inventory.
