Title: Sustainable Inventory modelling with Defect management and Conservation practices

Abstract:

Production of defectives in a manufacturing process is an inevitable process. The defective items have a thriving business in current world. The concept of conserving and recycling defective items has now become a recent trend for various industries as it aids in controlling detrimental environmental impacts caused by untreated defectives/waste. With such inducements, a vendor-buyer inventory strategy is formulated for a faulty production system considering carbon-emissions and defect management. The manufacturing process is governed by the vendor in which a fraction of defective items is produced. These items are screened out at vendor’s end only through a careful inspection and it is made sure that only good quality lot is delivered to the buyer. The inspection process classifies defectives into three categories, viz. repairable, reusable and recyclable depending upon their condition. Such an approach aids in fetching revenue and helps in waste reduction thereby contributing towards a green environment. The vendor also considers carbon-emission costs due to transportation and defect management as a step towards sustainability. An integrated model is developed and the total profit is maximized by jointly optimizing the number of shipments, order quantity and backordering quantity. Numerical analysis and sensitivity analysis is performed to establish the validity and robustness of the developed study.
