The stochastic uncapacitated lot-sizing problems with incremental quantity discount have been studied in this paper. First, a multistage stochastic mixed integer model is established by the scenario analysis approach and an equivalent reformulation is obtained through proper relaxation under the decreasing unit order price assumption. The proposed reformulation allows us to extend the productio...

Determining an order quantity when quantity discounts are available is a major interest of material managers. A supplier offering quantity discounts is a common strategy to entice the buyers to purchase more. In this paper, EOQ models with incremental discounts and either full or partial backordering are developed for the first time. Numerical examples illustrate the proposed models and solutio...

Quantity discount pricing is a common practice used by business-to-business and business-toconsumer companies. A key characteristic of quantity discount pricing is that the marginal price declines with higher purchase quantities. In this paper, we propose a choice-based conjoint model for estimating consumer-level willingness-to-pay (WTP) for varying quantities of a product and for designing op...

In this paper, a single-vendor, single-buyer supply chain for fixed lifetime product is considered. We propose models to analyze the benefit of coordinating supply chain through quantity discount strategy. Under the proposed strategy, the buyer is requested to alter his current order size such that the vendor can benefit from lower costs, and quantity discount is offered by the vendor to compen...

This paper develops a model for illustrating how to use quantity discount policy to achieve supply chain coordination. A supplier–buyer system selling one type of product with multi-period and probabilistic customer demand is considered. We first show that if both the buyer and supplier can find a coordination mechanism to make joint decisions, the joint profit in this situation is more than th...

Faical – maybe we should just focus this paper purely on the WTP estimates and the issue of the whether quantity discount strategies would be a warranted marketing strategy. So review the organic WTP studies and quantity discount literature – my guess is that no one has evaluated the issue of quantity discounts in organic food marketing. This will be the contribution of our study. No need to me...

In this paper we study the coordination of the two-echelon supply chain using credit and quantity discount options. We determine the retail price, order quantity for the buyer, and the setup frequency, credit period for the supplier in four different scenarios (with or without coordination and with or without credit option). And we suggest a policy that incorporates both quantity discount and c...

Previous ordering cost reduction vendor–buyer inventory models with backorder price discount usually assumed that the buyer must pay to the vendor for the ordered items as soon as the items are received, the received quantity is same as the ordered quantity and the transportation cost is independent of the shipment lot-size. In practice, however, the vendor is willing to offer the buyer a certa...

The ordering model between single supplier and multi-retailers under the circumstance of non-cooperation supply chain is discussed in this paper, an improved linear price discount strategy is also provided. This strategy considers two situations of incremental discount and decremental discount at the same time. Moreover, Stackelberg game model of both parties’ order on supply and demand is give...
