03 Nov Use the ‘Tractor Unit Sales’ ‘World’ data for 2012
Use the ‘Tractor Unit Sales’ ‘World’ data for 2012, 2013 and 2014 and calculate forecasts for next 3 years (2015, 2016, 2017) using exponential smoothing with trend adjustments method.You can find the formulas on powerpoint page 37. Note: 2012-2014 data will be considered the actual values and you will calculate forecasts for 2015-2017 using those actuals. You will calculate Ft, Tt and FIT each as a column. FIT column will be the SUM of Ft and Tt in each row. Use α=0.4 and B=0.2. Assume the first period’s sales (Ft) to be 2500 Units and the first period’s trend (Tt) to be 100. Then Calculate MAD for your FIT forecast.
