The conflict between the manufacturer and the retailer except the double marginalization is an important issue in order to coordinate the dual-channel supply chain. In the general case of the non-linear stochastic demand which also is affected by the sales effort of the retailer, this paper designs a new buy-back contract to coordinate the dual-channel supply chain. On the base of developing th...

In this paper, we study return policy and supply chain coordination in a channel of one supplier and one retailer. The paper assumes that unsold merchandise should been refunded to the supplier by the retailer. The retailer knows the cost of reverse logistics operations but the supplier has to estimate it. The contract menu under asymmetric reverse logistics cost information between supply chai...

We study the effects of credit risk in a supply chain where one retailer deals with competing risky suppliers who may default during their production lead-times. The suppliers, who compete for business with the retailer by establishing wholesale prices, are leaders in a Stackelberg game with the retailer. The retailer, facing uncertain future demand, chooses order quantities while weighing the ...

The process of extracting knowledge from data involves the discovery of patterns of interest which may be implicit, for instance, in speciÞc clusters of data points. In the context of Internet retailing, Þnding clusters of typical consumer types is among the most important uses of data mining techniques. Cluster-based market segmentation models, grounded on surveys of customer opinion, can give...

We first describe how to “fuzzify” the estimated binary columns to create a [0,1]-valued column. Werefer to this [0,1] -valued column as the soft segmentation column of the noisy spectrogram column.Similarly to the collection of soft segmentation columns as the soft segmentation image, or simply asthe soft segmentation. The band-dependent posterior probability that the hard segmentation columnv...

Consider a two-level inventory system consisting of one supplier and one retailer. The retailer faces a Poisson demand with a known rate and applies base stock (one-for-one ordering) policy. That is, his inventory position is set to a pre-determined level, so the demand pattern is transferred exactly to the supplier. The supplier has an inventory system and a service unit with exponentially dis...

This paper considers a single-item, two-echelon, continuous-review inventory model. A number of retailers have their stock replenished from a central warehouse. The warehouse in turn replenishes stock from an external supplier. The demand processes on the retailers are independent Poisson. Demand not met at a retailer is lost. The order quantity from each retailer on the warehouse and from the ...

The use of VMI at Wal-Mart on a large scale has attracted a great deal of attention in the industrial world. In a VMI program, the supplier assumes control of the inventory management for one or more retailers (Fry, 2002). The supplier monitors the inventory level at the retailers and makes the decisions related to the quantities of replenishment and the timing of shipments to the retailers. It...
