2.3 Decomposition
Following are the prediction results using the Decomposition method
as shown in Figure. 3.

Figure 3. Decomposition Output.
Figure. 3. shows the output of the predicted central oxygen supply
using the Decomposition method. Descriptively, the central oxygen
supply is seasonal, seen from the black line that shows the actual
data, the red line shows the estimated value, while the blue line shows
the predicted results. With an error value of MAD = 1.0523, MSD =
1.8326, and MAPE = 25.68.
