Information and decentralization in inventory, supply chain, and transportation systems
… single-item, 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 …

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 …

Integrated supply chain models and analysis
… reports on three integrated supply chain problems that incorporate several key components of modern supply chains, including location, transportation, inventory, and customer selection. The first part of the dissertation investigates a multi-product, three-stage distribution system with …

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 …

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 …

The Markov chain Monte Carlo approach to importance sampling in stochastic programming
… programming models are large-scale optimization problems that are used to facilitate decision-making under uncertainty. Optimization algorithms for such problems need to evaluate the expected future costs of current decisions, often referred to as the recourse function. In practice, this …

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) …

New applications in Revenue Management
… we first present a two-part tariff pricing problem faced by a satellite data provider. We estimate unobserved data with parametric density functions in order to generate instances of the problem. We propose a mixed integer programming formulation for pricing. As the problem is hard to solve, …

Stochastic Programming Approaches to Multi-product Inventory Management Problems with Substitution
… impact of substitution on inventory management problems by theoretically analyzing mathematical models and developing efficient solution approaches. To that end, we address four problems. In the first problem, we study different pricing strategies and the role of substitution for new and …

Three Essays on Data-driven Revenue Management and Pricing
… and pricing. In Chapter 2 we study the problem when a firm sets prices for products based on the transaction data, i.e., which product past customers chose from an assortment and what were the historical prices that they observed. Our approach does not impose a model on the distribution …

Analysis of the Benefits of Resource Flexibility, Considering Different Flexibility Structures
… demand only. We formulate this decision problem as a two-stage stochastic programming problem with recourse, and characterize the structural properties of the firm's optimal resource investment strategy when resource flexibility and pricing flexibility are considered in the investment …

Design and Performance Prediction for Supply Chain Systems with Graphical Structures
… optimal solution, which is similar to the newsvendor problem. Finally, in a numeral test, we find that the assembly decomposition is very effective but computationally expensive and thus only good for small-scale systems; the distribution decomposition performs as effective as the optimal …

Four Essays on Inventory and Supply Chain Management
