Prepare a master schedule given this information: It is now the end of week 1; customer orders are 25 for week 2, 16 for week 3, 11 for
week 4, 8 for week 5, and 3 for week 6. Use the MPS rule of ordering production when projected on-hand inventory would be
negative without production. Suppose that there were 64 pumps in inventory at the beginning of week 1. A production lot size of 70
pumps is used. (Leave no cells blank - be certain to enter "0" wherever required.)

A production lot size of 70 pumps is used. (Leave no cells blank - be certain to enter "0" wherever required.)
Prepare a master schedule given this information: The forecast for each week of an eight-week schedule is 60
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:

Use a production lot size of 73 units and no beginning inventory. (In the ATP row, enter a value of 0 (zero) In any
perlods where ATP should not be calculated. Leave no cells blank - be certain to enter "0" wherever required.)
