Recovery Option-Based Hybrid Combinatorial Remanufacturing Strategy for PCB-Based Products
For printed circuit board(PCB)-based products where the components rely on PCB for electrical interconnection,hybrid combinatorial remanufacturing strategies are proposed based on the quality statuses and recovery options of recycled products,aiming to minimize remanufacturing costs by optimizing individual decisions and component utilization.To quickly generate and solve the optimization models,the disposal costs are accurately measured by logical operations of binary codes.Moreover,extensive numerical experiments are conducted to examine the applicability and effectiveness of the models and algorithms proposed.It is found that products with high material costs and low operating costs are suitable for hybrid combinatorial remanufacturing,which is consistent with the reality of consumer electronic products,where the factory-refurbished version is scheduled to go on sale as routine.The Inter-SKU combination proposed can be expected to reduce the cost by over 10%and 30%than the Inner-SKU combination and no combination,respectively,where the reuse of high-value chips contributes to the cost reduction.The remanufacturing strategies and algorithms proposed in this paper are helpful for manufacturers to achieve lean remanufacturing,improve the efficient use of resources,and promote the realization of China's"dual carbon"goal.
