Robust Control strategy for an Uncertain Dual-Channel Closed-Loop Supply Chain with Process Innovation for Remanufacturing

The inventory and total cost control strategy are the core issue in all supply chains. When a chain includes parameter uncertainty, dual-channel process innovation for remanufacturing (PIR), system is complex so that its stability can’t be guaranteed easily. Therefore, how to manage uncertain closed-loop (CLSC) with PIR big challenge. CLSC studied this article. First of all, mathematical model established based on current operation cost. Secondly, converted an multi-model according different initial cases which then described set switching subsystem discrete Takagi-Sugeno(T-S) fuzzy model. Thirdly, robust H ∞ approach introduced restrain bullwhip effect deal impacts caused by uncertainty. Meanwhile, also obtained method. At last, three simulation tests conducted illustrate effectiveness strategy.
