Exponential smoothing uses both past forecasts and past demand data to generate a new forecast by assigning more weight to recent data and less weight to older data. This helps to capture any changes or trends in the data over time. The other models listed (naive, moving average, weighted moving average, and trend projection) only use past demand data to generate a new forecast.
