This should confirm that the optimum find is the maxi- mum of the region studied and its surroundings and suggests that it is likely that larger values of the objective function may not be obtained even outside the range of study. This process of opti- mization shows very positive results increasing the Stab-LSR flow around 17.55%, which is a significant improvement in production. The results obtained in the optimization process are shown in Table 10. Download 244.37 Kb. Do'stlaringiz bilan baham: |
