Single machine scheduling in make to order environments: A systematic review

The single machine scheduling problems are still present in industry 4.0. The scheduling depends on several factors, variables, and specificity of each production environment, and make to order settings are in this context. As a typical environment in several companies, there are still methods to be developed and applied to solve production scheduling problems. This paper investigates by a systematic literature review (SLR) which approaches are used to resolve and validate methods for solving production sequencing problems on single machine in make to order environments. This study investigated the limitations classified in 13.89% Specific operations, 19.44% Scale, and 8.33% Processing time. And identified gains in 61.11% of the publications, which the main were reduction of setup time and computational. From this paper it is concluded that there is a gap of research with real applications of sequencing methods in make to order environments. Further studies can be directed to the study of scheduling in single machine in these environments, with low processing times and efficiency within acceptable standards.
