The proposed study addresses a supplier-retailer inventory problem by considering the detrimental impacts of deterioration. The inventory produced by the supplier undergo a machine-shift and hence, produces non-conforming items. The retailer uses the preservation technology to deal with deteriorating items ingeniously where the demand is price-sensitive at the buyer’s end. Two models are developed through different means viz. Integrated and Bi-level approach and compared so to impart some constructive organizational insights. Sensitivity analysis was done over a numerical example to validate strength of the developed models.
