An economic order quantity model with backordering and increasing demand under two-level trade credit in circular economy

In today’s competitive market, however, the seller frequently offers the customer a grace period in which to settle the product’s account. Trade credit can be used by both the supplier and the buyer to increase the desires of their clients. In this paper, we developed sthe quadratic increasing demand function of time and allowed to delay payment under two levels of trade credit with the circular economy. We analyze the two-level trade credit on a seller’s optimum decision-making EOQ model with permissible Shortages. The aim of the inventory system is to define the EOQ model with a circular economy by using the Lagrangian method to find optimal profit.
