Question: Given the weekly demand data, what are the exponential smoothing forecasts for periods 2-05 using a=0.10?

Week Demand 0.1
1 980
2 825
3 760
4 650
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.

2. hmmm. So who is gona start the discussion.

week demand 0.10
1 980 980
2 825 980
3 760 964.5
4 650 944.05
5 914.645

4. hmmmzzz. good discussion

4 650 944.05

Ft = Ft-1 + a (At-1 – Ft-1)
F2= 980+0.1(980-980) = 980
F3= 980+0.1(825-980) = 964.5
F4= 964.5+0.1(760-964.5) = 944.05
F5= 944.05+0.1(650-944.05) = 914.645
