A large Portland manufacturer wants to forecast demand for a piece of pollution-control equipment. A review of past sales (A,), 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 T, was 2.00 units. Using trend-adjusted exponential smoothing, Forecasts (Fr), Trend (T), and Forecasts Including Trend (FIT) for months 1 through 4 have already been developed and are provided below. Continue with the process and determine Fr, T, and FIT, for months 5 and 6 (round your responses to two decimal places): Month Actual Demand (t) (A₂) Forecast (F₂) Trend (T₂) Forecast Including Trend (FIT) 1 10.0 9.00 2.00 11.00 2 18.0 10.80 1.92 12.72 3 24.0 13.78 2.34 16.12 4 20.0 17.70 2.97 20.67 5 22.0 15.26 6 22.0 16.61 7 32.0 8 26.0 9 38.0 10
