  摘要：Malaria is a major health concern for many developing countries. Designing strategies for efficient distribution of malaria medications, such as Artemesinin Combination Therapies, is a key challenge in resource constrained countries. This paper develops a solution methodology that integrates strategic-level and tactical-level models to better manage pharmaceutical distribution through a three-tier centralized health system, which is common to sub-Saharan African countries. At the strategic lev...

• Starting Prices in Liquidation Auctions for IT Equipment: Evidence from Field Experiments AI翻译

  摘要：It is widely accepted that the information technology (IT) industry has high clockspeed. This very phenomenon has led to IT OEMs finding themselves selling new generation models only to be left holding returned merchandise from older generations. Similarly, customers who migrate to newer generations of products experience uncertainty about how to dispose of older but functional IT equipment. Online liquidation markets have emerged to address these needs by finding ways to resell this equipment...
• Electric Vehicle Virtual Power Plant Dilemma: Grid Balancing Versus Customer Mobility AI翻译
  作者：Kahlen, Micha T.; Ketter, Wolfgang; van Dalen, Jan

  摘要：Virtual power plants (VPP) play a crucial role in balancing the electricity smart grid. VPPs aggregate energy from decentralized sources, for example, biogas, solar panels, or hydropower, to generate and consume electricity on demand. We study the management of electric vehicle (EV) fleets organized in VPPs as a way to address the challenges posed by the inflexible energy supply of renewable sources. In particular, we analyze the potential of parked EVs to absorb electricity from the grid, and...
• Dynamic Pricing through Data Sampling AI翻译

  摘要：We study a dynamic pricing problem, where a firm offers a product to be sold over a fixed time horizon. The firm has a given initial inventory level, but there is uncertainty about the demand for the product in each time period. The objective of the firm is to determine a dynamic pricing strategy that maximizes revenue throughout the entire selling season. We develop a tractable optimization model that directly uses demand data, therefore creating a practical decision tool. We show computation...
• Dose-Optimal Vaccine Allocation over Multiple Populations AI翻译

  摘要：Vaccination is an effective way to prevent an epidemic. It results in immunity for the vaccinated individuals, but it also reduces the infection pressure for unvaccinated people. Thus people may actually escape infection without being vaccinated: the so-called herd effect. We analytically study the relation between the herd effect and the vaccination fraction for the seminal SIR compartmental model, which consists of a set of differential equations describing the time course of an epidemic. We...
• Data Science Applications in Indian Agriculture AI翻译

  摘要：Agricultural supply chains in the developing world face the daunting task of feeding a growing population in the coming decades. Along with the provision of food, sustaining livelihoods, enhancing nutrition and the ability to cope with rapid changes in the environment and marketplaces are equally important to millions of small farmers. Data science can help in many ways. In this article, we outline the beginnings of data science applications in Indian agriculture. We cover various initiatives ...
• Research in Operations Management and Information Systems Interface AI翻译

  摘要：Owing to its multidisciplinary nature, the operations management (OM) and information systems (IS) interface distinguishes itself from the individually focused perspective of both fields. The number and depth of contributions in this department can help both disciplines advance to better address important theoretical and practical challenges of the business world. In this paper, we study the characteristics of problems at the interface between OM and IS, and review past work that has been inst...
• The Perils of Sharing Information in a Trade Association under a Strategic Wholesale Price AI翻译
  作者：Shamir, Noam; Shin, Hyoduk
  作者单位：Tel Aviv University; University of California System; University of California San Diego
  摘要：We study the incentives of a group of retailers, organized as a trade association and sourcing the product from a single manufacturer, to exchange private forecast information. We compare two widely used policies by the trade association in practice: exclusionary information exchange and non-exclusionary information exchange. Under the exclusionary policy, only retailers who contribute their private information are exposed to the pool of shared information, whereas under the non-exclusionary p...
• Product Recall Decisions in Medical Device Supply Chains: A Big Data Analytic Approach to Evaluating Judgment Bias AI翻译

  摘要：This study investigates judgment bias (under-reaction or over-reaction) in product recall decisions by firms when they respond to adverse event reports generated by users of their products. We develop an integrative theoretical framework for identifying the sources of judgment bias in product recall decisions. We analyze user-generated reports (big and unstructured data) on adverse events related to medical devices, using a combination of econometric and predictive analytic methods. We find th...
