Question
A dry cleaner uses exponential smoothing to forecast equipment usage at its main plant. August usage was forecasted to be 70 percent of capacity; actual usage was 74 percent of capacity. A smoothing constant of .4 is used.
A. prepare a forecast for Septemeber (round your final answer to 2 decimal places.)
Forecast for September _______ percent of capacity
B. Assuming actual September usage of 78 percent, prepare a forecast for October usage. (Round your answer to 2 decimal places.)
Forecast for October ______ percent of capacity.
Explanation / Answer
Let the capacity be 100
August forecast = 70% of 100 = 70
actual usage for August = 74
alpha (smoothing constant) = 0.4
forecast for september = actuals *alpha +(1-alpha)* forecast
74*0.4+(1-0.4)*70
= 29.6+42 = 71.6
B. Actual september usage = 78
forecast for october = actuals *alpha +(1-alpha)* forecast
= 78*0.4+(1-0.4)*71.6
=31.2+42.96 = 74.16
