摘要：Problem definition: We study a nurse staffing problem under random nurse demand and absenteeism. Although the demand uncertainty is exogenous, the absenteeism uncertainty is decision-dependent, that is, the number of nurses who show up for work partially depends on the nurse staffing level. For quality of care, hospitals develop float pools of hospital units and train nurses to be able to work in multiple units (termed cross-training) in response to potential nurse shortages. Methodology/resul...

摘要：Problem definition: In this paper, we present a reinforcement learning (RL)based framework for optimizing long-term discounted reward problems with large combinatorial action space and state dependent constraints. These characteristics are common to many operations management problems, for example, network inventory replenishment, where managers have to deal with uncertain demand, lost sales, and capacity constraints that results in more complex feasible action spaces. Our proposed programmabl...

摘要：Problem definition: We study a feature-based pricing problem with demand censoring in an offline, data-driven setting. In this problem, a firm is endowed with a finite amount of inventory and faces a random demand that is dependent on the offered price and the features (from products, customers, or both). Any unsatisfied demand that exceeds the inventory level is lost and unobservable. The firm does not know the demand function but has access to an offline data set consisting of quadruplets of...

摘要：Problem definition: We study the impact of an airline's route-level decisions on the efficiency and resilience of its operations. Methodology/results: Our study uses a proprietary passenger-level data set provided by Southwest Airlines and takes advantage of a regulatory change, the Wright Amendment repeal. The Wright Amendment restricted nonstop service between Dallas Love Field Airport (DAL) and most major destinations. Its repeal led to significant changes in Southwest's service offerings a...

摘要：Problem definition: This paper investigates how a crowdfunding campaign's voluntary disclosure of sensitive cost information affects its funding performance on Kickstarter-a mainstream, primarily reward-based crowdfunding platform. Instead of enhancing a campaign's marketing traits, project budget as a novel information-provision tool reminds the crowd of the behind-the-scenes operations for developing and executing a project. This resembles the radical practice of cost transparency recently o...

摘要：Problem definition: In this paper, we compare laissez-faire and mandatory authorization policy regimes for third-party remanufacturing. Under a laissez-faire policy, an independent remanufacturer (IR) chooses whether to get the original equipment manufacturer (OEM) authorization. Under a mandatory authorization policy, the IR is required to get OEM authorization and to pay the OEM a fee for every item remanufactured. Motivated by China's regulatory journey that first mandated authorized remanu...

摘要：Problem definition: The asymmetric pull-to-center effect for newsvendors is a robust finding in operations, and understanding why newsvendors make suboptimal decisions is key for identifying ways to improve decision-making quality in this critical task. Although prior studies have indicated that experience does not substantially mitigate the pull-to-center effect, the experience levels achieved in those previous studies are limited in comparison with the experience level that a near-continuous...

摘要：Problem definition: Motivated by carbon emissions trading schemes (ETSs), Treasury auctions, procurement auctions, and wholesale electricity markets, which all involve the auctioning of homogeneous multiple units, we consider the problem of learning how to bid in repeated multiunit pay-as-bid (PAB) auctions. In each of these auctions, a large number of (identical) items are to be allocated to the largest submitted bids, where the price of each of the winning bids is equal to the bid itself. In...

摘要：Problem definition: The improper disposal of electronic and electrical goods at the end of their useful lives (i.e., e-waste) can have adverse effects on the environment and human health. The increased awareness of the negative consequences of e-waste has prompted many regulators to enact recycling standards that promote the proper disposal and recycling of e-waste. A large body of research has used analytical models to explore how recycling standards affect firms that make electronic and elec...

摘要：Problem definition : The clean energy transition is an important component of the net zero transformation, which aims at averting potentially disastrous climate change related to excessive global warming by practically eliminating new global greenhouse gas emissions within 2050. The resulting move toward decarbonized energy systems is projected to encompass massive investments in assets that employ technologies with low environmental impact, some of which are innovative or yet unproven or even...
