  摘要：Recent estimates suggest that more than 40 million people worldwide are in situations of modern slavery and other forms of labor exploitation. UN Sustainable Development Goal 8.7 addresses this problem and urges stakeholders to take effective measures to end all forms of labor exploitation by 2030. Labor exploitation is often a direct consequence of forced migration, and humanitarian operations have a key role to play in tackling this issue worldwide. Academic research can facilitate this by p...
• Is it Time to Include Post-Transplant Survival in Heart Transplantation Allocation Rules? AI翻译
  作者：Hasankhani, Farhad; Khademi, Amin

  摘要：Identifying an efficient and fair allocation of limited donated hearts to patients on the waiting list is one of the top priorities in heart transplantation management. The recent heart allocation rule by the United Network for Organ Sharing (UNOS) has emphasized medical urgency to address the heart transplant crisis by further dividing the previous sickest patient group into three subgroups. However, there is a significant debate on optimality and fairness of this policy because although it c...
• Decisions Under the Illusion of Objectivity: Digital Embeddedness and B2B Purchasing AI翻译

  摘要：Research suggests that increased reliance on digital sources (e.g., blogs, social media, online forums) exhibited by the emerging millennial workforce may affect procurement decisions. These arguments contend with studies which indicate that organizational buyers rely on decision shortcuts (e.g., brand, loyalty, and peer opinions) to mitigate risk or to simplify purchase decisions. One can argue that buyers gain more information from digital sources, which may attenuate the role of these short...
• The Knowledge Value Chain: An Operational Perspective AI翻译

  摘要：The successful launch of an innovative product or service is driven by an unexplored market opportunity or a technological breakthrough. Oftentimes, however, firms lack the necessary resource capabilities to exploit new market opportunities; alternately, markets may not exist for firms to successfully profit from technological breakthroughs. In other words, firms suffer from performance gaps between their market opportunities and their resource capabilities. In this study, we organize the grow...
• Elicitation of Preference among Multiple Criteria in Food Distribution by Food Banks AI翻译

  摘要：The United Nations Sustainable Development Goals provide a road map for countries to achieve peace and prosperity. In this study, we address two of these sustainable development goals: achieving food security and reducing inequalities. Food banks are nonprofit organizations that collect and distribute food donations to food-insecure populations in their service regions. Food banks consider three criteria while distributing the donated food: equity, effectiveness, and efficiency. The equity cri...
• Robust Bilevel Resource Recovery Planning AI翻译

  摘要：In this study, we consider a resource recovery planning problem under a public-private partnership. The local authority's problem is to determine the waste sorting scheme, and also a cost-sharing budget, to minimize her expected payout, subject to a requirement of economic feasibility of the private operator. Given the budget and sorting scheme, the private operator's problem is to site and operate resource recovery facilities, and his goal is to maximize his expected total profits. A salient ...
• Supply Chain Carbon Footprinting and Climate Change Disclosures of Global Firms AI翻译
  作者：Blanco, Christian C.

  摘要：The content of climate change disclosures of large, global companies evolved from 2007 to 2016. Within that window, the same set of firms started measuring and disclosing their supply chain carbon emissions. Does carbon footprinting influence the nature and content of a firm's disclosure on the climate change risks that are expected to affect its business? We explore this question using more than 10,925 climate change disclosures collected by the CDP (formerly the Carbon Disclosure Project) fr...
• Simple Mechanisms for Sequential Capacity Allocations AI翻译

  摘要：We consider a sequential capacity allocation problem of a firm to its retail branches that sell the firm's product. The orders of the retail branches to the headquarters arrive sequentially, and each allocation decision has to be made before the next order arrives. The objective of the headquarters is to maximize the overall firm profit, that is, the total profit of all the retail branches. Each retail branch makes ordering decision independently by using private information about its local ma...
• Effect of Live Chat on Traffic-to-Sales Conversion: Evidence from an Online Marketplace AI翻译

  摘要：Over the years, online retailers have increasingly embraced live chat to improve customer service and facilitate transactions. We examine how online sellers' use of live chat influences their online traffic conversion into sales. Like brick-and-mortar stores, a fundamental task for online stores is to convert traffic into purchases, an important problem in retail service operations management. We argue that live chat can increase online sales conversion by performing the functions of informing...
• A Discussion of Non-Gaussian Price Processes for Energy and Commodity Operations AI翻译
  作者：Gambaro, Anna Maria; Secomandi, Nicola

  摘要：Energy sources and commodities exhibit high price risk. This risk is thus an important feature of operational models of the value chains for these goods. These models typically employ Gaussian-based representations of the evolution of this uncertainty. This approach facilitates the optimization of operational policies but is at odds with empirical facts about energy and commodity prices, which are better captured by non-Gaussian processes. We discuss this alternative modeling strategy, focusin...
