The uses of a certain material (kilograms) are shown in following table: a) Develop a 3-quarter weighted moving average forecasting model in which the material used in the most recent quarter is given a weight of 1.5 and the material used in the other 2 quarters is each given a weight of 0.7 . b) Develop an exponential smoothing forecasting model in which the smoothing constant for forecast is equal to 0.4 and the material used in Q1 / Y1 period is assumed to be 240 kilograms. c) Which of the developed forecasting model is considered to be more accurate?
