After plotting demand for four periods, an emergency room manager has concluded that a trend adjusted exponential smoothing model is appropriate to predict future demand. The initial estimate of trend is based on the net change of 30 for the three periods from 1 to 4, for an average of + 10 units. Use α = .5 and β = .4, and TAF of 250 for period 5. Obtain forecasts for periods 6 through10.
