Closed-loop supply chain switching model with outsourcing selection and its robust control

A type of closed-loop supply chain switching models with outsourcing selection were proposed,which were consisted of remanufacturing self-recall and outsourcing subsystems as well as a cost-based switching signal vector.To inhibit operation fluctuation caused by inventory switching processes in the supply chain systems and bullwhip effect induced by uncertain parameters and external demand,the control law of the closed-loop supply chain switching system was presented by using robust control theory and method.The operation process of closed-loop supply chain switching system was analyzed.Moreover,computation of the control law and a system simulation were performed.Results verified the effectiveness of the control law.
