Exercise 3:- Exponential Smoothing Suppose that, the previous forecast was 98 units, the actual demand was 100 units, and a = 10. The new forecast would be computed as follows: Ft Then, if the actual demand turns out to be 102, the next forecast would be: Ft = Fw,(4) W, (4) w..(4) where w, weight for period t, w, weight for period t 1, etc. 4, the actual value for period 1, 4, the actual value for period t 1, etc
