Dynamic Program Modeling for a Retail System under Trade Credit

چکیده
Dynamic programming has been used to solve numerous complex problems in business and engineering. This study applies dynamic programming to a retail decision-making problem related to trade credit. A price, shelf-space, and time-dependent demand function is introduced to model the finite time horizon inventory. Trade credit was considered in the model because suppliers commonly provide retailers with credit periods. Consequently, the retailer is not required to pay for goods immediately upon receipt, and can instead earn interest on the retail price of the goods between the time the goods are sold and the end of the credit period. The objective of this paper is to determine the periodic retail price, shelf-space quantity, and ordering quantity that maximize total profit. The numerical examples explain the procedures of the solution approach and show that dynamic decision making is superior to fixed decision making regarding profit maximization.

Mathematical Modeling for an Integrated Inventory System with Two-level Trade Credit and Random Defectiveness in Transport
Modern business environment focuses on improving the operational efficiency of supplier, retailer and customers through integrating their inventory. Although a smoothly running integrated inventory system is ideal, the reality is to deal with imperfectness in transportation. In actual production environments, inventory items are not perfect and defectiveness occurs in random process. In this p...

In this paper we develop an economic order quantity model to investigate the optimal replenishment policies for instantaneous deteriorating items under inflation and trade credit. Demand rate is a linear function of selling price and decreases negative exponentially with time over a finite planning horizon. Shortages are allowed and partially backlogged. Under these conditions, we model the ret...

In practice, the supplier often offers the retailers a trade credit period M and the retailer in turn provides a trade credit period N to her/his customer to stimulate sales and reduce inventory. From the retailer’s perspective, granting trade credit not only increases sales and revenue but also increases opportunity cost (i.e., the capital opportunity loss during credit period) and defau...
