200 Q* = Economic Order Quantity D = Annual Demand (in this case 15,000 units) S = Fixed cost per setup (in this case $100) H = Holding or Carrying cost ($75) Step 1: calculate 2*D (Annual Demand)*S(Setup Cost) 2*15,000*100 = 300,000 Step 2: Divide 2*D (Annual Demand)*S(Setup Cost)/H 300,000/75 = 40,000 Step 3: Take square root of 40,000 Square root of 40,000 = 200.

8 Therefore, 1 week (lead time for part Y) + 6 weeks (lead time for part Z) + 1 week (assembly time for product X) = 8 weeks cumulative lead time.
