Table 1. Model’s result using Rolling Horizon for April 2011. Extremes Ratio (%) CPU time (s) 3 Periods 73.3 9545 4 Periods 72.1 10327 CLC’s schedule 69.4 w/ Excel-worksheet
Table 2. Model’s result using Rolling Horizon for May 2011. Extremes Ratio (%) CPU time (s) 3 Periods 71.0 15110 4 Periods 70.6 1898
It is observed that dividing the April month in 3 periods has better results, both on extremes ratio and CPU time. On the other hand, for the month of May, although the extremes ratio is slightly higher for the division in 3 periods, the CPU time of the division in 4 periods is approximately 8 times lower.
