Disassembly modeling and planning are meaningful for the reuse and recycling of obsolete and discarded products. However, the existing disassembly methods pay little or no attention to impact of resources constraints for disassembly problem. According to the characteristics of lot sizing disassembly optimization problem with multiresource constraints, a mathematical model was established to solve disassembly optimization problems with multi-resource capacity constraints. The model aims at maximizing the profit of disassembly. The CPLEX software is used to solve the model. In order to approve the effectiveness of the proposed model, several randomly generated problem instances are used, the experimental results approved the effectiveness of the proposed model for the lot sizing disassembly optimization problem.
