The inventory model under supplier's partial trade credit policy in a supply chain system

A lot of researchers explore the inventory EOQ model under the assumption that the supplier would offer the retailer full trade credit but not partial trade credit. In practice, the supplier's partial trade credit policy is frequently adopted in business transactions. This paper incorporates a real payment mode in which the retailers could still gradually settle the partial payment in the inventory EOQ model under the supplier's partial trade credit. Some theorems for the optimal cycle time are also proposed.
