Question/Description 

Question: Given the weekly demand data, what are the exponential smoothing forecasts for periods 2-05 using a=0.10?
Week
Demand
0.1
1
860
2
730
3
690
4
610
5
Note: Calculation along with the formula is required for each period's forecast. Students who give answers without calculation will be given low marks/no marks.
::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
Solution:

Exponential Smoothing Model
Ft = Ft-1 + a (At-1 - Ft-1)
Where
Ft = Forecast value for the coming time period
Ft-1 = Forecast value in 1 past time period
At-1 = Actual occurrence in the 1 past time period
a = Alpha smoothing constant
