A green supply chain model for time quadratic inventory dependent demand and partially backlogging with Weibull deterioration under the finite horizon

摘要

This paper presents a detail solution of re-manufacturing of a product in a supply chain model. It is a non-traditional model considering time-dependent quadratic demand, Weibull deterioration, shortages, partial backlogging and re-manufacturing of inventory. This paper mainly focuses on remanufacturing and hence an attempt towards reducing the environmental hazard. The process of remanufacturing is completed within one cycle of replenishment. Trade credit between supplier and retailer also had been discussed. Two cases one of a centralized and the other of decentralization for a finite planning horizon in a supply chain model are discussed. An algorithm has been derived for solving a problem in both the cases. Some managerial insights are talked about on the basis of sensitivity analysis on the parameters considered.
