Consider the following actual and forecast demand levels for Big
Mac hamburgers at a local McDonald's restaurant:
Day Monday Tuesday Wednesday Thursday Friday Actual Demand 88.00 75.00 70.00 52.00 Forecast Demand 88.00 88.00 84.10 79.87 The forecast for Monday was derived by observing Monday's demand level and setting Monday's forecast level equal to this demand level. Subsequent forecasts were derived by using exponential smoothing with a smoothing constant of 0.30. Using this exponential smoothing method, the forecast for Big Mac...

A large Portland manufacturer wants to forecast demand for a piece of pollution-control equipment. A review of past sales (At), as shown below, indicates that an increasing trend is present. Smoothing constants are assigned the values of a = 0.20 and ß = 0.4. The firm assumes the initial forecast for month 1 (F1) was 9.00 units and the trend over that period T1 was 2.00 units. Using trend-adjusted exponential smoothing, Forecasts (Ft), Trend (Tt), and Forecasts Including Trend (FIT+)...
