摘要：In recent years, mobile communication technologies and online sharing platforms have made collaborative consumption among consumers a major trend in the economy. Consumers buy many products but end up not fully utilizing them. A product owner's self-use values can differ over time, and in a period of low self-use value, the owner may rent out her product in a product-sharing market. This study develops an analytical framework to study how consumer-to-consumer product sharing affects the distri...

摘要：Evaluating and quantifying human suffering in humanitarian operations offers an innovative and potentially powerful way to assess the performance of humanitarian logistics (HL) and help build optimization models. Previous studies have suggested deprivation cost as a metric and have estimated deprivation cost functions for water using willingness-to-pay. Our study proposes deprivation levels, defined as the degree of human suffering caused by lack of access to a good or service, and estimates d...

摘要：We study the funds allocation problem for a resource-constrained non-profit organization (NPO) that implements social development projects for public good. In addition to raising funds from donors who contribute prior to project implementation (traditional donors), the NPO uses a novel approach, which we term as the ex-post funding approach, to also raise funds from donors who contribute based on the results delivered by the NPO (ex-post donors). In this approach, the NPO uses its initial fund...

摘要：We consider a multi-stage inventory system with stochastic demand and processing capacity constraints at each stage, for both finite-horizon and infinite-horizon, discounted-cost settings. For a class of such systems characterized by having the smallest capacity at the most downstream stage and system utilization above a certain threshold, we identify the structure of the optimal policy, which represents a novel variation of the order-up-to policy. We find the explicit functional form of the o...

摘要：We study buyer-determined procurement auctions where both price and non-price characteristics of bidders matter for being awarded a contract. Although, in scoring auctions bidders perfectly know how price and non-price attributes determine the awarding of the contract, this remains uncertain in buyer-determined auctions where the buyer is free to choose once all bids have been submitted. We analyze the impact of information bidders have with respect to the buyer's awarding decision. As we show...

摘要：In developing countries, governments, non- governmental organizations, and social entrepreneurs are disseminating agricultural information to farmers to improve their welfare. However, instead of having direct access to the information, farmers usually acquire information from local social networks, and, thus, they may have very different information channels. We establish a general framework that accommodates highly asymmetric information structures to study farmers' information management an...

摘要：We consider a firm's sourcing problem from one reliable supplier and one unreliable supplier in two price-setting scenarios. In the committed pricing scenario, the firm makes the pricing decision before the supply uncertainty is resolved. In the responsive pricing scenario, the firm ' s pricing decision is made after the supply uncertainty is resolved. For the committed pricing scenario, we develop a condition on supply uncertainty that guarantees the unimodality of the firm's objective functi...

摘要：The current literature on the coordination of operations and finance does not differentiate long- and short-term debts and therefore is silent on how firms' debt maturity structure affects their short-run financial and operational decisions. Through a dynamic inventory model that explicitly captures a firm's periodic decisions on inventory replenishment quantity, the amount of dividends net of capital subscriptions, and the amount of short-term debt, we demonstrate that under coordinated short...

摘要：In this study, we examine the hospital's ability to admit patients from its emergency department. From a medical perspective, the number of patients being admitted should depend solely on the patients' clinical conditions. Using a large-scale econometric study that includes detailed operational and clinical data on all cardiac patient encounters from a set of 128 hospitals over a period of four years, we show that this is not the case. In particular, we find that independent of their medical c...
