Abstract:

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.

摘要： 拆卸建模和规划对废旧产品的回收和再利用具有重要意义,目前的拆卸方法很少关注多资源约束对拆卸问题的影响。根据批量拆卸优化问题的特点,建立了多资源约束下以拆卸获得收益最大为优化目标的批量拆卸优化问题的数学模型,采用CPLEX软件对多资源约束下批量拆卸优化问题进行求解。为了验证该模型在求解此类批量拆卸优化问题的有效性,采用多组随机算例的仿真实验对其验证,结果表明该模型求解此类问题有效。
