The master production schedule calls for gross requirements of 110 units of A in week 6 and 130 units in week 8, and for 70 units of B in week 5 and 160 in week 7. a) L4L J (1) K 260 500 2 1 Max 500 Ignore the line in the inventory records marked "Lot size" and assume the lot-sizing rule is L4L for all items (including H).
