Exponential smoothing is a weighted-moving-average forecasting technique that uses a weight, a, such that 0 a 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+ a(At-1- Ft-1) = A backpack manufacturer needs to forecast demand in week 5. The backpack demand is shown in Table 3. Table 3. Backpack demand Week 1 2 3 4 Demand 1403 1391 1360 1454 a) Using Table 3, a = 0.5, and a week 3 forecast of 1400, calculate the exponential smoothing forecast for week 4 and enter the correct whole number: b) Next, calculate the exponential smoothing forecast for week 5 and enter the correct whole number:
