Suppose a four period weighted average is being used to forecast demand. Weights for the periods are:
wt-4 = 0.1
wt-3 = 0.2
wt-2 = 0.35
wt-1 = 0.35
Demand observed in the previous four periods was:
At-4 = 15890
At-3 = 14970
At-2 = 14478
At-1 = 14628
What will be the demand forecast for period t? (Keep one decimal place in your answer).
Demand forecast for period t
= Wt-1 x at-1 + Wt-2 x At-2 + Wt-3 x At-3 + Wt-4 x At-4
= 0.35 x 14628 + 0.35 x 14478 + 0.2 x 14970 + 0.1 x 15890
= 5119.80 + 5067.3 + 2994 + 1589
= 14770.1
