We consider in this paper an Economic Order Quantity (EOQ) problem involving a single supplier that offers quantity discounts and allows retailers to delay payments. The retailers are tempted to form coalitions in order to minimize their costs. We propose a solution approach that generates stable coalition structures for the retailers taking into account the delay in payments and the discount q...

We consider the joint acquisition and pricing problem where the retailer sells multiple products with uncertain demands and the suppliers provide all unit quantity discounts. The problem is to determine the optimal acquisition quantities and selling prices so as to maximize the retailer’s expected profit, subject to a budget constraint. This is the first extension to consider supplier discounts...

This paper develops a powerful retailer inventory model under trade credit and quantity discounts in which the retailer’s order is calculated for each setup shipped equal lots over multiple deliveries. Furthermore, condition that must make partial payments cash given number of sub-shipments, with remaining balance paid time expires after depleted. integrated supply chain has not yet been discus...

This work presents the definition and solution of an optimization model using techniques based on the Particle Swarm Optimization (PSO) algorithm or the Particle Swarm Optimization and Genetic Algorithms. The model corresponds to the Joint Replenishment Problem in a system operating with quantity discounts. Results are shown in problems, where their size makes it difficult or impossible to esta...

We consider a two-period model with two sellers and one buyer in which the efficient outcome calls for the buyer to purchase one unit from each seller in each period. We show that when the buyer’s valuations between periods are linked by switching costs and at least one seller is financially constrained, there exist plausible conditions under which exclusion arises as the unique equilibrium out...
