Expоnentiаl smооthing is а weighted-moving-аverage forecasting technique that uses a weight, α, such that 0 ≤ α ≤ 1. When forecasters use exponential smoothing, the new forecast in period t is calculated using the moving average from last period’s (t-1) forecast and a percentage of the error from the last period’s forecast. New forecast = Last period’s forecast + weight x (Last period’s demand – Last period’s forecast) Ft = Ft-1 + α(At-1 – Ft-1) A wallet manufacturer needs to forecast demand in week 5. The wallet demand is shown in Table 2. Table 2. Wallet demand Week Demand 1 908 2 905 3 897 4 891 Using Table 2, α = 0.5, and a week 3 forecast of 913, calculate the exponential smoothing forecast for week 4 and enter the correct whole number: ___________. [43a] Next, calculate the exponential smoothing forecast for week 5 and enter the correct whole number: ___________. [43b]
Mаny services аnd prоducts experience seаsоnal fluctuatiоns. Adjusting uniform demand by a seasonal index ratio can help forecasters to replicate typical fluctuations. By following the seasonal forecasting steps below, you can create a seasonal forecast. Steps 1 and 2 have already been calculated in Table 3. Complete steps 3, 4, and 5 by filling in the last three columns of Table 3. Seasonal forecasting steps Calculate each seasonal average for the time horizon. Calculate the overall average for the time horizons. Calculate each seasonal index ratio by dividing the seasonal average (#1) by the overall average (#2) for each season. Estimate next horizon’s total demand. Divide next horizon’s total demand by the number of seasons per horizon (uniform demand). Calculate the seasonal forecast by multiplying uniform demand (#4) by the seasonal index (#3) for each season. For a creamery, fill in the last three columns of Table 3 if the estimate for ice cream cakes in the next horizon (Year 3) is 640 ice cream cakes.
