At present, augmentation of carbon gases in atmosphere has become a major concern. Regulatory bodies in many countries have focused on reduction of carbon emissions. Several countries follow carbon tax and carbon cap trade policy to control emission of carbon gases. This study has been carried out to obtain joint inventory policies for a supply chain involving a manufacturer and a whole-seller. Moreover, the manufacturer invests in green technology to reduce units of carbon gases. Products are considered deteriorating in nature. Manufacturer delivers product by adopting a lot-for lot policy to meet the whole-seller?s demand. The manufacturer offers the whole-seller flexible payment options including advance payment with discounted product price and delayed payment with increment in product price. Optimal policies for both individuals and the supply chain are discussed with aim to maximize total profit. The model is worked out and results are compared for four cases: (i) advance payment with green technology investments (ii) advance payment without green technology investments (iii) delayed payment with green technology investments (iv) delayed payment without green technology investments. A solution procedure has been proposed and explained through a numerical example. Study is concluded with managerial insights.

“…Sahoo et al [30] investigated about the policies of inventory for selling-price dependent demand under the condition of partially backlogging. Various authors e.g., Malik et al [31], Dari Sani [32], Shah et al [33] and Shah Naik [34] formulated inventory model for deteriorating items. Our research derives an inventory system for deteriorating medicinal products under the impact of inflation where demand depends on the price of a product.…”

This paper introduces an inventory system for declining medicinal products under the effect of ination with price-sensitive demand. Usually, pharmaceutical inventory systems assume the deteriorating rate as constant, which is insignificant and illogical because healthcare products medicines and drugs deteriorate significantly. Thus, the deteriorating rate of medicinal products is supposed to be time-dependent and to follow three-parameter Weibull distribution. The lack of commodities is permitted with the rate of partial backlogging. This research work develops a model to optimize the total average cost of the items by calculating the ordering quantity and the optimum time intervals. Finally, through a numerical example, with sensitivity analysis, we demonstrate the effect of different parameters.

“…Demand plays an important role in inventory management, the study of inventory systems can not be anticipated without addressing demand rates. Due to various facts of fluctuating demand in different situations, the inventory systems have been developed by considering demand depending on: price and stock dependent ( [11], [12], [13], [14]), quadratic form ( [15]), simply constant demand ( [16]), etc.…”

At the manufacturing plant or while the products are being transferred from one supply layer to another, there is a considerable possibility of receiving damaged or faulty items mixed in with non-defective commodities. This research focuses on the non-defective and defective products that are shipped to retailers by their suppliers. The retailer reworks faulty items to make them non-defective, and the retailer receives a discount on the cost of purchasing defective items. The presented inventory system addresses the uncertainty in inventory costs and also considers the deterioration of items with prioritized maximum product life. In this study, our aim is to minimize the total inventory cost when demand rate as a function of quality and power pattern of time under crisp and generalized triangular neutrosophic environments.Based on the payment deal, interest charges are imposed only when the payment delay has passed a particular allowable time limit. The neutrosophic number, which provides three different types of membership functions representing truth, hesitation, and falseness, is used in the inventory model to handle the cost pattern's uncertainty. A particle swarm optimization approach is used to analyze the proposed inventory model, and the results are validated using a numerical example and sensitivity analysis for various parameters.
