Answer:
a) This month = 342
b) Next month = 308
c) This month using simple exponential smoothing = 352.
Explanation:
a) Data and Calculations:
Month Demand 3-month Moving
Average
3 months ago 390
2 months ago 340
1 month ago 295
This month 342
b)
Month Demand 3-month Moving
Average
3 months ago 390
2 months ago 340
1 month ago 295
This month 290
Next month 308
c) Simple exponential smoothing
Forecast for three months ago = 440
Smoothing constant = 0.20
Forecast for this month = 440 * (1- 0.20) = 352
d) For the simple exponential smoothing, the most recent period's forecast is multiplied by (one minus the smoothing factor).
