Pharmacy keeps track of pills sold. Day 8: 49, day 9: 52, day 10: 48. What is MAD
coëfficiënt: 2 estimate for day 8: 50. What is MAD after 3 days? You have to use the
trend-adjusted exponential smoothing.

Bullwhip effect implies that demand variations are magnified downstream through
supply chain.

The weekly output of a fabrication process is shown below, together with data for
labour and material inputs. Standard selling price is $125 per unit. Overhead is
charged weakly at the rate of $1,500 plus .5 times direct labor cost. Assume a 40-hour
week and an hourly wage of $16. Material cost is $10 per foot.
What is the average multifactor productivity?

The owner of Darkest Tans Unlimited in a local mall is forecasting this month’s
(October) demand for the new tanning booth based on the historical data below.
What is this month’s forecast using exponential smoothing with alpha = 0,2, if
august’s forecast was 145?
Month Number of Visits
April 100
May 140
June 110
July 150
August 120
September 160
𝐹𝑡 = 𝐹𝑡−1 + α(𝐴𝑡−1 − 𝐹𝑡−1)
September = 145 + 0,2(120-145) = 140
October = 140 + 0,2(160-140) = 144
What is not important when looking at a time-based strategy?
● Flexibility
● Cost minimization
● Reducing complaints solution time
“Products fifty per cent over budget but introduced on time have been found to generate
higher profit levels than products brought to market within the budget but six months late”
What is a non-operating intermediary?
● Bonded warehouse
● Freighted forwarder
● UPS
● None
