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...

摘要：Problem definition: In response to the increased use of telehealth to replace traditional office visits with a physician, several U.S. states have recently adopted telehealth pay-parity policies. Such policies state that payers must reimburse healthcare providers for telehealth services at the same rate that would apply if those services had been provided in a traditional office setting. But health policy researchers have pointed out that telehealth may not be as effective as a traditional off...

摘要：Problem definition: In this paper, we investigate how line-sitting and express lines affect customers' satisfaction and fairness perception about queues. In line-sitting, customers skip the wait by hiring others to stand in line on their behalf. In express lines, customers skip the wait by purchasing priority. Because both schemes disrupt the first-infirst-out (FIFO) rule, they may be perceived to be unfair and lead to customer dissatisfaction. Methodology/results: In three experiments, we fin...

摘要：Problem definition: This paper studies the joint estimation of the consumer arrival rate and choice model parameters when no-purchasers (customers who considered the product but did not purchase) are not observable. Estimating this unconstrained demand even with the simplest discrete-choice model such as the multinomial logit (MNL) becomes challenging as we do not know the fraction that have chosen the outside option (i.e., not purchased). Methods have been proposed to use market share to pin ...

摘要：Problem definition: Limited resources in the judicial system can lead to costly delays, stunted economic development, and even failure to deliver justice. Using the Supreme Court of India as an exemplar for such resource-constrained settings, we apply ideas from service operations to study delay. Specifically, court dynamics constitute a casemanagement queue, whereby each case may experience multiple service encounters spread across time, but all are necessarily with the same server. Our goal ...

摘要：Problem definition: Prototyping and testing are an integral part of almost any new product development process, helping firms navigate the inherent uncertainties of creating new products. Recent developments in rapid prototyping, including technologies that enable cheaper low-fidelity tests, have opened up the possibilities for firms in reconfiguring their product development processes. Firms can, by choosing the level of evaluation fidelity, alter the traditional cost-quality trade-offs inher...

摘要：Problem definition: This paper examines the impact of retail store closures on omnichannel sales and consumer shopping behavior in the context of the coronavirus disease 2019 pandemic. To explain the likelihood of store closure, we develop a novel instrumental variable motivated by varying geopolitical responses across the United States to the pandemic. Methodology/results: Using data from a luxury fashion retailer, we find that when a store is closed, the volume of online orders originating f...

摘要：Problem definition: This work aims to examine the role of emergency department (ED) operational status related to congestion in fast-track (FT) routing decisions and the subsequent effects on patient outcomes. Methodology/results: In this paper, we utilize a two-year data set from two hospital EDs in Alberta, Canada, and adopt an instrumental variable approach to examine the effects of FT routing decisions on patient outcomes. Based on the empirical findings, we utilize a data-calibrated simul...
