Assignment 1 The following table contains the demand from the last 10 months: AL DAN AR De 1 a. Calculate the single exponential smoothing forecast for these data using an a of 30 and an initial forecast (F.) of 31. b. Calculate the exponential smoothing with trend forecast for these data using an a of 30, a 8 of 30, an initial trend forecast (T.) of 1, and an initial exponentially smoothed forecast (F.) of 30 C. Calculate the mean absolute deviation (MAD) for each forecast. Which is best? Exponential Absolute Absolute Month Demand smoothing deviation T F FIT, deviation 31 31.00 1.00 30.00 31.00 1 2 34 3 33 4 35 5 37 6 36 7 38 8 40 9 40 10 41 MAD Based upon the MAD of each forecast, the exponential smoothing with trend is the better forecasting model
