Capacitated Multi-Period Multi-Product Disassembly Scheduling with Parts Commonality and Partial Disassembly

In a green supply chain, preventing the disposal of used products and reusing them will help to protect the environment. The most important step in the closed-loop supply chain is the disassembly and recovery of used products and their reuse in producing new products. In this paper, we propose a new mixed-integer programming model to consider a multi-period multi-product disassembly scheduling problem based on parts commonality and partial disassembly. Considering partial disassembly is the main contribution of this paper. When the disassembly is partial, the parts with no demand will not disassemble; so, a lot of time and cost will be saved. The proposed model is solved using CPLEX Solver, and sensitivity analysis is deployed to validate the model and determine the proposed model's practical results. Numerical experiments shows that the CPLEX solver has a good efficiency for solving the developed model in small and medium dimensions.
