Determination of optimal pricing, shipment and payment policies for an integrated supplier-buyer deteriorating inventory model in buoyant market with two-level trade credit
Summary: In this paper, an integrated supplier-buyer inventory model is studied when the units in inventory are subject to deterioration at a constant rate, the market demand is quadratic and sensitive to retailer price and the supplier offers a trade credit. The trade credit policy under assumption is ``two-part'' strategy viz. ``net credit'', that is, retailer has a choice between cash discount and trade credit. ``Net credit'' means that, if the buyer pays within time period \(M_{1}\), then the buyer receives a cash discount, otherwise, the full account must be settled before time period \(M_{2}\) where \(M_{2} > M_{1} \geq 0\). The goal is to determine the optimal pricing, ordering, shipping and payment policy to maximise the joint profit per unit time. An algorithm is given to obtain an optimal solution. A numerical example is given to validate the proposed model and to arrive at managerial insights.
