RESUMO

This work deals with the single machine scheduling problem with earliness and tar- diness penalties. Sequence dependent setup times and distinct due windows are con- sidered. To solve this problem, a three-phase heuristic approach was developed. The rst phase is based on GRASP and Variable Neighborhood Descent to generate an initial solution; the second phase is based on a Tabu Search for solution rening, and nally Path Relinking is used as a mechanism of post-optimization as a third pha- se. For each job sequence generated by the heuristic, an optimal timing algorithm is used to determine the completion time for each job in the job sequence. Computatio- nal experiments carried out show that previous algorithms found in related literature have been improved, regarding the quality of the nal solution and the average gap.
