An end item’s demand
- Develop an MPS for this end item.
- The marketing department has received five orders for this item in the following sequence:
Order 1 is for 20 units to be delivered in period 1.
Order 2 is for 75 units to be delivered in period 4.
Order 3 is for 90 units to be delivered in period 6.
Order 4 is for 75 units to be delivered in period 7.
Order 5 is for 90 units to be delivered in period 10.
Assuming that the prospective MPS you developed in part (a) does not change, which orders would you be able to accept based on the available to promise (ATP)?
