) The following data have been prepared for master production scheduling purposes in IKEA Australia:
End product A: Beginning inventory of 60, Period forecast of 10, Lot size of 30, and 30 hours in lot size.
End product B: Beginning inventory of 20, Period forecast of 5, Lot size of 20, and 20 hours in lot size.
End product C: Beginning inventory of 30, Period forecast of 15, Lot size of 50, and 50 hours in lot size.
Capacity: 38 hours/ week
(i) Prepare the master production schedule for these items during the next four periods using the Ethan Allen master production scheduling method.
(ii) Suppose that the master production schedule is frozen for the next three periods. What specific impact would the policy have on the IKEA's performance?
