A store has the following demand figures for the last four years:
Year Demand 1 100 2 150 3 98 4 112
What is the exponential smoothing forecast for year 5? Use alpha = 0.3 and a forecast for year 2 of 100.
Computation of Exponential smoothing forecast for Year 5:
F(3) = 0.3*Actual(2) + (1-0.3)*F(2)
= 0.3*150 + 0.7*100
= 115
F(4) = 0.3*98 + 0.7*115
= 109.9
F(5) = 0.3*112 + 0.7*109.9
= 110.53
So, Exponential smoothing forecast for Year 5 is 110.53
