Table 1: Quarterly demand information over past four years.
You were assigned to conduct this supplier selection exercise. In order to carry out this
exercise, you managed to collect quite a lot of data. You first managed to collect the
demand history, on a quarterly basis, over the past four years. The demand data is shown
in Table 1. Based on the observation of the demand, you decided to use a static time series
model to estimate the level, trend and seasonality
