Abstract

The increasing world population and amount of consumption cause increased waste. Recycling valuable materials in waste is also important for environmental awareness and cost. On the other hand, processes such as recycling, reprocessing, disassembly, etc. of end-of-life products are reverse supply chain activities and the re-marketing of used products is realized through these activities. The first stage of recycling, disassembly, can be defined as the process of completely or partially separating products into the parts that constitute them. Optimizing the disassembly line's efficiency directly impacts the process's overall performance. However, variations in the characteristics and the quantity of end-of-life products, along with fluctuations in supply and demand, necessitate task reallocation and adjustments to the cycle time. Therefore, in such instances, it becomes necessary to the rebalancing of the disassembly line. Hence, the study emphasizes the necessity of addressing the reverse supply chain and rebalancing of disassembly lines in an integrated manner, discussing the challenges faced due to the complex nature of this integration. The applicability and effectiveness of integer programming and constraint programming methods in overcoming these challenges are examined. It highlights the significant advantages of constraint programming's flexibility and the precision of integer programming in overcoming the challenges encountered. These findings contribute to the literature on reverse supply chain management and rebalancing of disassembly line, offering new directions for future research.
