Simulated Annealing Based Hybrid Forecast for Improving Daily Municipal Solid Waste Generation Prediction

Table 2

Comparison of three models and SA based hybrid forecast. Forecast efficiency degrading means the average degradation of the neighboring week in RMSE.

Predictability (RMSE, 2nd week average)	93.31	103.96	91.21	87.65
Predictability (RMSE, 3rd week average)	99.41	111.69	93.79	90.16
Predictability (RMSE, 4th week average)	113.61	114.46	104.30	96.55
Predictability (RMSE, 5th week average)	103.16	132.74	108.72	99.23
Forecast efficiency degrading (RMSE)	10.06	9.99	5.10	4.75
