This section adapts large-sized problem instances from the FJSP literature. Data set 4 consists of ten instances adapted from those proposed by Brandimarte [6], which involve 10, 15, and 20 jobs, 55 - 240 operations, and 4 - 15 machines. Data set 5 refers to the modified version of the 21 instances designed by Chambers … See more We use three simple procedures to compute lower bounds and then use the best of the three to infer on the quality of the heuristic solutions. The procedures are based on the three … See more Kumar et al. [20] modified the benchmark instances proposed by Bilge and Ulusoy [5] by considering that each operation can be done in one of three alternative machines. The original 82 instances were … See more The problem instances in this data set were proposed in [13] and have been used in all reported works on the FJSPT, except that of Kumar et al. [20]. These instances use the ten job sets … See more Data sets 1 and 2 are both adapted from the instances proposed by Bilge and Ulusoy’s [5] for the JSPT.
