Sequencing and scheduling in disassembly shops: a review of problem formulations and solution approaches

End-of-life product recovery is mandatory for some industries and presents opportunities and challenges for (re-)manufacturers. Disassembly planning models can help decision-makers save costs and make processes more sustainable. In a disassembly facility dealing with various product types and utilizing specialized workstations with different equipment, multiple decisions arise regarding the priority of jobs and the time-wise allocation of tasks to resources. This work presents an overview of the literature on sequencing and scheduling decisions in the disassembly shop. Since the models under review do not uniformly classify within the existing taxonomy of disassembly problems, the term disassembly shop floor scheduling (DSFS) is used. In total, 58 research articles are identified and classified systematically by searching and analyzing the literature. After discussing the different problem formulations and solution approaches, the review outlines important directions for further research, including job shop-type disassembly and the consistent use of benchmark instances for DSFS.
