Illustrative Example: Production Line with 10 Workstations
!
Simulation model for a production line with 10 workstations.
-
The minimum value for the average cycle time selected as the first best solution (first incumbent solution) (I-1), is identified from the initial experimental design and corresponded to a value of 176.36 minutes for the Random design, 173.02 minutes for the Mersenne Twister Design, 172.06 minutes for the Clustering Design, 170.59 minutes for the LCG Design, and 170.06 minutes for the D-Optimal.
-
In this example, the best solution when the algorithm stopped corresponded to a system time of 167.39 minutes for the Random Design, 165.41 minutes for the Mersenne Twister Design, 166.36 minutes for the Clustering Design, 165.17 minutes for the LCG Design, and 167.02 minutes for the D-Optimal.
-
When a comparison between the initial incumbent solution (I-1) with the final one (I-9) was performed, the result was that the system time decreased in 8.97 minutes for the Random Design, 7.61 minutes for the Mersenne Twister Design, 5.70 minutes for the Clustering Design, 5.42 minutes for the LCG Design, and 3.04 minutes for the D-Optimal. This represents a reduction of 5.1, 4.4, 3.3, 3.2, 1.8%, respectively, in the system time per unit in the simulated production system.
