摘要：In practice, lead time demand (LTD) can be skewed, multi-modal or highly variable, and these factors compromise the validity of typical approaches used for setting safety stock levels. Motivated by encountering this problem at our industry partner, we develop an approach for setting safety stock levels using the bootstrap, a widely used statistical procedure. Existing bootstrap approaches for inventory management either operate directly on observed LTD or assume deterministic lead times, permi...

摘要：This work addresses the issue of intelligent robot-human-coordinated parts-to-picker order fulfillment carried out in a human-friendly manner. One unique feature of the proposed approach involves integrating a real-time data-driven stochastic-dynamic model with a fatigue accumulation function. The optimal solutions help achieve coordination between human pickers and robots, such that robots can agilely adapt to the coordinated pickers' efficiency and fatigue conditions. Specifically, the propo...

摘要：The COVID-19 pandemic presented the world to a novel class of problems highlighting distinctive features that rendered standard academic research and participatory processes less effective in properly informing public health interventions in a timely way. The urgency and rapidity of the emergency required tight integration of novel and high-quality simulation modeling with public health policy implementation. By introducing flexibility and agility into standard participatory processes, we alig...

摘要：Much interest exists in physicians' ability and willingness to adapt their practice styles, as research demonstrates that many physicians practice in ways that are not aligned with the best available scientific evidence. We exploit migration patterns of primary care physicians in Massachusetts over a span of 8 years by tracking physician migrations to practice sites comprised of new peers who shared actual physical working space. We examined whether a patient's likelihood of receiving an inapp...

摘要：This paper provides evidence that the formation of global supply chain partnerships leads to an increased usage of cross-border financing. The findings are detected in all three major financing markets-equities, syndicated loans, and public debt. Difference-in-differences tests allow us to draw a causal interpretation of our main findings, which also holds in several robustness tests. Our findings suggest that increased cross-border financing reflects greater ability to access global financial...

摘要：Online retailers employ various kinds of social and marketing information cues to influence consumers' product interest and purchases. This study focuses on the effects of two types of information cues, product popularity and time restriction on product promotions, on consumers' product approach behavior. It takes a unique perspective by examining how such effects change as consumers' shopping goals become more concrete. The results of a field experiment and a laboratory experiment show that p...

摘要：Online peer-to-peer (P2P) lending has emerged as an innovative financial technology (FinTech) platform that renders financial services that are potentially more inclusive and affordable than those offered by traditional financial institutions. A similar purpose is served by cryptocurrency markets, where transaction costs are reduced and financial accessibility is improved based on disruptive technologies such as blockchain and distributed ledgers. Despite these developments, however, in the op...

摘要：In many settings, consumer surplus directly impacts a firm or organization's objective, and the profit-only objective becomes inadequate. Our paper is the first to consider the dual objective of profit and consumer surplus in multi-product pricing under the multinomial logit demand, where the prices are continuously set. We define a firm's marginal consumer surplus as its marginal contribution to the expected customer utility transformed into monetary unit. Although the profit is concave in th...

摘要：A retailer places orders periodically for items that are shipped by a wholesaler. Items that are not sold perish randomly and independently of one another, with the perish probability depending on the age class. We consider a first-in-first-out policy for depleting items. We model this problem as a Markov decision process with stochastic demand, unit holding, outdating and ordering costs, plus unit penalty costs for lost sales. We prove convexity for the penultimate period and show convexity m...

摘要：Many firms are adopting an everything or anything as a service-XaaS-model to sell goods and value-added services. Buyers for such goods are heterogeneous both in the number of units they desire and the valuations for each unit. Suppliers designing such revenue models can offer either a usage-based per-unit fee or an access-based per-period fee, often combining them both as a nonlinear two-part tariff plan that imposes both types of fees on all buyers or let buyers self-select from a menu of pe...
