Using a newsvendor model for demand planning of NFL replica jerseys
… a single period. The approach taken utilizes the newsvendor model to determine the optimal stocking levels of replica jerseys given an expected demand forecast. Two modeling approaches were compared, the traditional newsvendor problem and a newsvendor model with risk pooling. The traditional …

Newsvendor Analysis of Supply Chains: Issues of Product Design and Channel Conflicts
… as the study of supply chain management within a newsvendor framework. We first study a price-setting newsvendor's product design problem within the context of a centralized supply chain. We find that as a general rule, the newsvendor should lower quality facing demand uncertainty. In contrast, …

Clusterización y aplicación del método Newsvendor para optimizar los perfiles de sobreventa en vuelos single leg
… de políticas óptimas a través de un modelo tipo Newsvendor bajo supuestos de demanda con distribución empírica acumulada de no-shows, y la operacionalización de dichas políticas en producción mediante un clasificador basado en XGBoost. Los vuelos son segmentados en tres perfiles de demanda, Alta, …

Data-driven revenue management
In this thesis, we consider the classical newsvendor model and various important extensions. We do not assume that the demand distribution is known, rather the only information available is a set of independent samples drawn from the demand distribution. In particular, the variants of the model we …

Coordination and competition in resource-constrained channels
… a profit. We prove this for the one-supplier/one-newsvendor supply channel as well as the many-supplier/one-newsvendor channel configuration (with each supplier selling a unique product). We analyze how this set of wholesale prices changes as we change the channel's capacity constraint. We also …

Information and decentralization in inventory, supply chain, and transportation systems
… single-period inventory control problem: the "newsvendor problem." We first analyze the newsvendor problem when the demand distribution is only partially specified by some moments and shape parameters. We determine order quantities that are robust, in the sense that they minimize the …

Discrete Choice-based Equilibrium Modeling of Supply Chain Network with Conflicting Objectives and Demand Uncertainty
… supply chain network equilibrium model and the newsvendor model are generalized and relaxed in order to obtain more general solutions and methods. First, this PhD thesis adopts Sheffi’s equilibrium condition assumption rather than Wardrop’s network equilibrium condition assumption. Discrete …

Determining optimal inventory levels for items nearing the end of a production run
… no following period's demand. In this thesis, a newsvendor inventory optimization model which considers salvage value and initial inventory level along with two alternative (s, S) model formulations are tailored to fit items nearing the end of a production run. One of the (s, S) inventory models …

Initial purchase of short-term life cycle products with uncertain demand
… errors and life cycle management, and the newsvendor problem was applied to the data sample to determine the optimal purchase which was then compared to Targus' purchases. It was found that Targus has a tendency to under-purchase items for the initial purchase and does not establish …

A Seasonal Shelf Space Reorder Model Decision Support System
<p>The traditional newsvendor model results in a decision to reorder an item whenever the expected profit from the reorder is positive. Candidates for reorder include all items selling more quickly than had been anticipated during preseason forecasts and ordering. Retailers must also decide how to …

Integrated supply chain models and analysis
… location-inventory problem in a multi-retailer newsvendor setting with both decentralized and centralized decision making. The third part of the dissertation explores the coordination between operations management and marketing through an integration of marketing strategies and the inventory …

Essays on Inventory Management and Object Allocation
… objects to agents. In the second, we study a newsvendor model where the inventory manager has access to two experts that provide advice, and examine how and when an optimal algorithm can be efficiently computed. In the third, we study classical single-resource capacity allocation problem and …

Supply Chain Design With Cross Sales, Product Design, and Price -Setting Competitive Newsvendors
… retailer, which is modeled as a price-setting newsvendor. A multiplicative demand function incorporating a random factor &egr; is assumed. Results indicate the following: if &egr; is uniformly distributed on [0, x], then the equilibrium design does not depend on the variance of &egr;; if &egr; …

Stochastic Programming Approaches to Multi-product Inventory Management Problems with Substitution
… retailer. Our second problem is a multi-product newsvendor problem with customer-driven demand substitution. We completely characterize the optimal order policy when the demand is known and reformulate this nonconvex problem as a binary quadratic program. When the demand is stochastic, we …

Optimization of CPG budgets in Retailer-led marketing programs
… Considering uncertainty in redemption, the Newsvendor model was also explored to review the possibility of over-allocation to improve budget utilization and increase reach. The preliminary analysis findings offer promising results and provide a setting for further research.

Benefits of postponement for fashion products with forecast updates
… production process is modelled as a two stage newsvendor problem and the forecast update path follows an additive martingale. An optimal solution and a myopic solution are proposed to solve this problem. Numerical results indicate that the benefit of postponement decreases with the overage cost …

Coordinating the multi-retailer, single supplier procurement processes for a seasonal product with supply contracts
… In traditional supply contracts, retailers use a newsvendor approach to maximize their profits, while the supplier's profits increase linearly as a function of the number of units supplied to retailers. Initially, retailers assume risk in the supply chain because they are facing an unknown demand, …

The Markov chain Monte Carlo approach to importance sampling in stochastic programming
… experiments in which we solve variants of the Newsvendor problem. Our results show that even a simple implementation of our framework produces highly accurate estimates of the optimal solution and optimal cost for stochastic programming models, especially those with increased variance, …

Supply chain coordination and influenza vaccination
… chain has characteristics that resemble the Newsvendor problem, but possesses several characteristics that distinguish it from many other supply chains. Differences include a nonlinear value of sales (caused by the nonlinear health benefits of vaccination that are due to infection dynamics) …
