Low carbon sustainable inventory model with screening and rework process under preservation technology investment Available to Purchase

Nowadays, supply chain management having challenges in the form of emission reduction, imperfect production, and deteriorating products. Therefore, this study develops a manufacturer-retailer supply chain for deteriorating products with the inflation’s effect when imperfect items are formed. When the production ends, the manufacturer begins screening to categorize the perfect and defective items. After the screening, faulty items were sent for rework. The “cap-and-trade” policy is adopted to mitigate the emission. Preservation and green technology reduce the deterioration rate and carbon emission, respectively. An algorithm is used to solve the proposed model. This study furnishes the numerical illustration to obtain the optimal strategies for green technology investment, cycle time, and preservation technology investment. To highlight the most significant results, an extensive sensitivity assessment is performed over the input parameters. The result of this model shows that the rework process mitigates the emission and minimizes the total cost compared to all defective products being scrapped.
