Optimal configuration of remanufacturing supply network with return quality decision
研究了制造商在多个再制造设施下，如何同时决定设施运营、退货质量门槛、退货量和需求分配，以最大化系统利润，并分析了退货量、成本、质量与需求不确定性等因素的影响。
This research studies the configuration problem of a remanufacturing production network together with the decision for return quality thresholds, in which, the manufacturer has multiple remanufacturing facilities to satisfy different market demands. Quality of returns is stochastic, while demand for remanufactured products is either stochastic or deterministic. The problem we considered is to determine facilities to operate, minimum quality to accept into each operating facility, return quantity and demand allocation simultaneously so that the system’s profit is maximised. The problem is formulated as a mixed integer non-linear programming model. Through the use of a numerical example, the impact of quantity of returns, total spending, quality uncertainty, demand uncertainty and transportation cost on the remanufacturing system is analysed.
