Answer #1
Answer: Alpha= 0.30
Explanation:
Absolute deviation= |Forecast - Sales|
MAD= mean absolute deviation= sum of absolute deviation/no. of periods
the formula to be used in Exponential smoothing is
Ft+1= alpha*At + (1-alpha) Ft
At means Actual demand of t'th month, if you want to find out the Forecast through exponential smoothing= forecast of 3rd month = alpha*actual demand of 2nd month+(1-alpha) *forecast demand of 2nd month
remember forecast of 1st month is actual demand of 1st month
