Traditionally, supplier selection should simultaneously take into account numerous heterogeneous criteria, and then is a tedious task for the purchasing decision makers. It becomes especially complicated when quantity discounts are considered at the same time. Under such manner, most studies often formulate such a problem as a Multi-Objective Linear Programming (MOLP) problem, and then scale it...

In the supply-chain literature, an increasing body of work studies how suppliers can use incentive schemes such as quantity discounts to influence buyers’ ordering behaviour, thus reducing the supplier’s (and the total supply chain’s) costs. Various functional forms for such incentive schemes have been proposed, but a critical assumption always made is that the supplier has full information abo...

Consider a distribution system consisting of a set of retailers facing a single-period price-dependent demand of a single product. By taking advantage of the risk-pooling effect and the quantity/volume discount provided by suppliers or thirdparty carriers, the retailers may place joint orders and keep inventory at central warehouses before demand realization, and allocate inventory among themse...

Background: Determining the optimum shipment quantity in a traditional production system is competitive business dimension, and developing reliable policy decisive for long-term objectives. Currently, significant research this domain has mainly focused on lot sizing perfect without considering imperfections processes logistics. It been well established that real inventory acts as an imperfectio...

Supply chains are often in an environment where the demand is affected by the retailer’s sales effort and the supplier has no accurate information about the retailer’s cost. In this situation, the retailer’s action of distorting his cost information could damage the efficiency of the supply chain. In order to reduce the resulted impairment, the problem of how to coordinate the retailer’s action...

The use of price to influence a buyer’s purchasing behavior and thus improve supply chain coordination has received considerable attention. The vendor and buyer are independent economic entities, each maximizing its own profit. We consider the case of a buyer with fixed annual demand, independent of cost. The vendor’s objective is to set a price schedule that encourages the buyer to raise its o...

In this research, an integrated supplier-buyer inventory system is studied when market demand is price-sensitive trapezoidal and units in inventory are subject to deterioration at a constant rate. The buyer has an option to choose between discount in unit price and delay in settling the account against the purchases made offered by the supplier. This type of trade credit is termed as ‘net credi...

the existing works considering the flow-based discount factor in the hub and spoke problems, assume that increasing the amount of flow passing through each edge of network continuously decreases the unit flow transportation cost. although a higher volume of flow allows for using wider links and consequently cheaper transportation, but the unit of flow enjoys more discounts, quite like replacing...

This article studies the classical reorder quantity, order point (Q, r) continuous review stochastic inventory model with Poisson arrivals and a fixed lead time. This model has been extensively studied in the literature and its use in practice is widespread. This work extends previous research in this area by providing efficient algorithms for the computation of the optimal (Q∗, r∗) values when...

The high adoption of smart mobile devices among consumers is an opportunity for ecommerce retailers to increase their sales by recommending consumers with real time, personalized coupons which take into account the specific contextual situation of the consumer [5]. While context-aware recommender systems (CARS) have been widely analyzed [1,2] personalized pricing or discount optimization in rec...
