  摘要：Most previous studies on reliable facility location design assume that disruptions at different locations are independent. In this paper, we present a model that allows disruptions to be correlated with an uncertain joint distribution, and we apply distributionally robust optimization to minimize the expected cost under the worst-case distribution with given marginal disruption probabilities. The worst-case distribution has a practical interpretation with disruption propagation, and its sparse...
• Newsvendor Selling to Loss-Averse Consumers with Stochastic Reference Points AI翻译

  摘要：We study a newsvendor who sells a perishable asset over repeated periods to consumers with a given consumption valuation for the product. The market size in each period is random, following a stationary distribution. Consumers are loss averse with stochastic reference points that represent their beliefs about possible price and product availability. Given the distribution of reference points, they choose purchase plans to maximize their expected total utility, including gain-loss utility, befo...
• Capacity Investment in Renewable Energy Technology with Supply Intermittency: Data Granularity Matters! AI翻译

  摘要：We study an organization's one-time capacity investment in a renewable energy-producing technology with supply intermittency and net metering compensation. The renewable technology can be coupled with conventional technologies to form a capacity portfolio that is used to meet stochastic demand for energy. The technologies have different initial investments and operating costs, and the operating costs follow different stochastic processes. We show how to reduce this problem to a single-period d...
• Sales Force Behavior, Pricing Information, and Pricing Decisions AI翻译

  摘要：This paper focuses on salespeople behavior in business-to-business transactions. The paper investigates how salespeople use the information provided to them to set prices; of particular interest is how salespeople use price recommendations from a decision support tool. The investigation builds reduced-form models and tests them on a data set obtained by a grocery products distributor. The analysis shows that salespeople's decisions are explained well by a two-stage decision model whereby sales...
• Dynamic Assortment Customization with Limited Inventories AI翻译

  摘要：We consider a retailer with limited inventory of identically priced, substitutable products. The retailer faces a market with multiple segments of customers that are heterogeneous with respect to their product preferences. Customers arrive sequentially, and the firm decides which subset of products to offer to each arriving customer depending on the customer's preferences, the inventory levels, and the remaining time in the season. We show that it is optimal to limit the choice set of some cus...
• The Price of Nonabandonment: HIV in Resource-Limited Settings AI翻译

  摘要：The global fight against HIV/AIDS is hindered by a lack of drugs in the developing world. When patients in these countries initiate treatment, they typically remain on it until death; thus, policy makers and physicians follow nonabandonment policies. However, treated patients develop resistance to treatment, so in many cases untreated patients might benefit more from the drugs. In this paper we quantify the opportunity cost associated with restricting attention to nonabandonment policies. For ...
• Parametric Forecasting and Stochastic Programming Models for Call-Center Workforce Scheduling AI翻译

  摘要：We develop and test an integrated forecasting and stochastic programming approach to workforce management in call centers. We first demonstrate that parametric forecasts, discretized using Gaussian quadrature, can be used to drive stochastic programs whose results are stable with relatively small numbers of scenarios. We then extend our approach to include forecast updates and two-stage stochastic programs with recourse and provide a general modeling framework for which recent, related models ...
• Combating Strategic Counterfeiters in Licit and Illicit Supply Chains AI翻译

  摘要：Counterfeit goods are becoming more sophisticated, from shoes to infant milk powder to aircraft parts, creating problems for consumers, firms, and governments. By comparing two types of counterfeiters-deceptive, so infiltrating a licit (but complicit) distributor, or nondeceptive in an illicit channel-we provide insights into the impact of anticounterfeiting strategies on a brand-name company, a counterfeiter, and consumers. Our analysis highlights that the effectiveness of these strategies de...
• Incentive Contracts in Serial Stochastic Projects AI翻译
  作者：Chen, Tony; Klastorin, Ted; Wagner, Michael R.
  作者单位：University of Washington; University of Washington Seattle
  摘要：In this paper we propose an incentive payment contract for stochastic projects defined by a series of stages or tasks that are outsourced to independent subcontractors. Projects defined by sequentially completed independent stages are common in new product development and other high-risk projects. Our goal is to maximize the client's expected discounted profit. Our proposed contract reflects the convex time-cost trade-off that is well known in the project scheduling literature. We show that th...
• Demand Estimation from Censored Observations with Inventory Record Inaccuracy AI翻译
  作者：Mersereau, Adam J.
  作者单位：University of North Carolina; University of North Carolina Chapel Hill
  摘要：A retailer cannot sell more than it has in stock; therefore, its sales observations are a censored representation of the underlying demand process. When a retailer forecasts demand based on past sales observations, it requires an estimation approach that accounts for this censoring. Several authors have analyzed inventory management with demand learning in environments with censored observations, but the authors assume that inventory levels are known and hence that stockouts are observed. Howe...
