AB This paper studies a sustainable inventory model for items whose demand rate is the product of a time-dependent function and a price-dependent function. The inventory system allows shortages during the productmanagement period. Carbon emissions from transportation and storage are included in the model. Theconsideration of a demand rate that combines the effects of a price-algebraic function and a time-powerfunction, with full backlogging and environmental constraints, is a novel and more realistic hypothesis andit should be studied. To determine the optimal inventory policy for this system can help to improve theefficiency and sustainability practices in inventory control. The objective is to determine a sustainable inventorypolicy that maximizes the average profit per unit time. We include the following significant components in theobjective function: the average revenue, the ordering cost, the purchasing cost, the shipping cost, the holdingcost, the shortage cost, and the carbon emissions costs in transportation and storage. To find the solution tothis sustainable inventory problem, four scenarios are analyzed and, for each scenario, the optimal inventorypolicy is obtained. This policy determines the lot size, the optimal selling price, the maximum shortage, and themaximum profit per unit time. Some numerical examples are presented to illustrate the proposed methodologyfor determining the optimal policy of this sustainable inventory problem. We examine the effects on the bestinventory policy when some parameters of the system are changed. Useful managerial insights derived fromthese results are proposed.
