  3. Ch. 11 – 3 a. r = dm = 20(5) = 100 Since , both inventory position and inventory on hand equal 100. b. r = dm = 20(15) = 300 Since , both inventory position and inventory on hand equal 300.

  4. c. r = dm = 20(25) = 500 Inventory position reorder point = 500. One order of Q* = 400 is outstanding. The on-hand inventory reorder point is 500 - 400 = 100. d. r = dm = 20(45) = 900 Inventory position reorder point = 900. Two orders of Q* = 400 are outstanding. The on-hand inventory reorder point is 900 - 2(400) = 100.

  5. Ch. 11 – 7 Where is the revised order quantity for the new carrying charge . Thus

  6. Ch. 11 – 17 EOQ Model Total Cost Planned Shortage Model

  7. Total Cost • Cost Reduction with Backorders allowed • $848.53 - 791.25 = $57.28 (6.75%) • Both constraints are satisfied: • 1. S / Q = 39.56 / 303.32 = 0.13 • Only 13% of units will be backordered. • Length of backorder period = S / d = 39.56 / (800/250) • = 12.4 days
