Modeling for the operation of closed-loop supply chain with remanufacturing

The operation process for a class of closed-loop supply chain system with remanufacturing is considered. In this system, the manufacturer is in charge of reclaiming and re-disposal of the returned products. The remanufacturing costs like operation costs for disassembling collected product and refurbishing disassembled part, and disposal costs of disassembled part are all uncertain. Based on the early research results, an operation model is constructed to maximize the total profits by optimally deciding the number of purchased parts from external suppliers, the quantity of parts to be processed at each remanufacturing facilities. A numerical example is designed, and the results shown that the model is both solution-robust and model-robust.
