Retailers have long recognized that some categories aremore important than others in consumers’ store choice decisions. The overall profitability of a store requires careful categorylevel merchandising decisions to draw the most desirable consumers into the store. However, the traditional accounting measure of category profits offers imperfect helpmaking these decisions since it does not take i...

in this paper, a system of gig/l/k queue is considered. the optimal system's capacity (k), when the system is optimized with respect to the benefit of the entire system (social optimization) and when the criterion for optimality is individual gains (individual optimization), is determined and compared. in social optimization, the system capacity is obtained through maximization of the syst...

This article deals with supply chain systems in which lateral transshipments are allowed. For a system with two retailers facing stochastic demand, we relax the assumption of negligible fixed transshipment costs, thus, extending existing results for the single-item case and introducing a new model with multiple items. The goal is to determine optimal transshipment and replenishment policies, su...

Taxes levied on retail sales are a ubiquitous form of taxation, both in the US and abroad. While considerable study has examined the economic effects of such sales taxes vis-a-vis consumer demand, surprisingly little attention has been focused on the effects up the supply chain. In this paper, we consider a parsimonious model of retail products sold in a variety of consumer markets (each of whi...

In this research we use previously seen data and weekly forecasts of sales and customers, to predict the amount of workforce required in a retail store. The data set contains a difficulty, the target values for observations are latent. We do however have aggregated target values and know that these targets are a sum of the latent values. We assume retailers are cost minimizing agents and approa...

In this paper, a supply chain model between manufacturing firm and group of retailers has been developed. Manufacturing produces simultaneously both perfect imperfect items which are separated by screening process. Then the transferred to retailers’ showroom/warehouse located in different places part repaired rework Retailers receive products from manufacturer with paying partial pre-payment en...

The joint replenishment problem has been extensively studied and the strategy adopted by a large variety of retailers in recent years. However, under minimum order quantity other constraints does not receive sufficient attention. This paper analyzes retailing supply chain involving supplier that provides discount schedules limits quantity. include requirements for each item as to total quantity...

This paper develops a single wholesaler and multi retailers mixture inventory distribution model for a single item involving controllable lead-time with backorder and lost sales. The retailers purchase their items from the wholesaler in lots at some intervals throughout the year to meet the customers’ demand. Not to loose the demands, the retailers offer a price discount to the customers on the...

Supply chain performance measures include both profit and risk. In this study, we examine the effect of retailers’ minimum profit share concerns on supply chain system performance through laboratory experimental and analytical modeling approaches. In the experiment, each retailer’s minimum profit share, which partially reflects her self-serving fairness concern, is measured with a parameter def...

This study considers the pricing and inventory decisions for retailer selling in multiple markets with strategic customers. The impact of customer behavior on pooling is examined. equilibrium decisions, which customers tend to purchase early, are subsequently characterized pooled/non-pooled systems. Our results highlight role each market. Compared myopic customers, prone reduce its retailer’s o...
