Answer:
The forecast will be 397....
Step-by-step explanation:
We have given:
Weights for the periods are.
wt-4 = 0.1,
wt-3 = 0.2,
wt-2 = 0.3
and wt-1 = 0.4
Demand observed in the previous four periods was as follows:
At-4 = 380,
At-3 = 410,
At-2 = 390,
At-1 = 400
The demand forecast will be:
= 0.1*380+0.2*410+0.3*390+0.4*400
= 38+82+117+160
= 397
Thus the forecast will be 397....
