摘要：Despite the prevalence of multiproduct firms in many industries, the supply chain contracting literature has predominantly focused on problems where an upstream player offers only one product. This paper studies multiproduct contract design for competing manufacturers each with several products to sell via a common retailer. We consider two contracting schemes under multinomial logit demand (MNL): individual contracting, in which the manufacturers set a wholesale price for each of their produc...

摘要：One of the greatest challenges of the COVID-19 pandemic has been the way evolving regulation, information, and sentiment have driven waves of the disease. Traditional epidemiology models, such as the SIR model, are not equipped to handle these behavioral-based changes. We propose a novel multiwave susceptible-infected-recovered (SIR) model, which can detect and model the waves of the disease. We bring together the SIR model's compartmental structure with a change-point detection martingale pro...

摘要：The tariff rate quota (TRQ) is a widely utilized market access instrument in global agricultural trade that allows a predetermined quantity of a product to be imported at a lower tariff rate than the usual rate. This study examines the design and administration of TRQ systems from an operations management perspective and analyzes their impact on market access, fill rates, and revenue for policymakers. We investigate the two most common TRQ administration methods, namely, licensing and first-co...

摘要：We develop a general framework for selecting a small pool of candidate solutions to maximize the chances that one will be optimal for a combinatorial optimization problem, under a linear and additive random payoff function. We formulate this problem using a two-stage distributionally robust model, with a mixed 0-1 semidefinite program. This approach allows us to exploit the diversification effect inherent in the problem to address how different candidate solutions can be selected to improve th...

摘要：The aging population and increasing chronic disease load are rapidly changing the face of primary care delivery, with mid-level (e.g., nurse) practitioners providing growing proportion of patient care. Potential differences in the quality of care offered by physicians and nurse practitioners may affect patient preferences, thus leading to patient choice behavior. This paper focuses on the problem of appointment scheduling for physician-nurse teams in the presence of patient choice and no-shows...

摘要：We consider a general class of price-based network revenue management problems that a firm aims to maximize revenue from multiple products produced with multiple types of resources endowed with limited inventory over a finite selling season. A salient feature of our problem is that the firm does not know the underlying demand function that maps prices to demand rate, which must be learned from sales data. It is well known that for almost all classes of demand functions, such as linear, exponen...

摘要：The proliferation of social networking platforms like Facebook, Twitter, Instagram, and TikTok has greatly facilitated social interactions among individuals, and thus their product consumption has become more visible to their peers. This enhanced visibility influences consumers' purchase decisions of luxury products because it affects social value derived from conspicuous consumption of these products. In this paper, we develop an analytical model to study the impact of such social technologie...

摘要：We study the value of information in a supply chain where the manufacturer introduces a direct-selling channel to encroach in the retailer's market. Based on different information structures regarding the direct-selling cost for the manufacturer, we analyze three models: incomplete information model, asymmetric information model, and full information model. By comparing the firms' profits in these models, we derive the value of the manufacturer's information acquisition and the value of sharin...

摘要：The global economic disruption brought by COVID-19 crisis can set a stage for the prevalence of financial statement frauds, which jeopardize the efficient functioning of capital markets. In this paper, we propose a nuanced method to detect frauds by tracking granular changes in disclosures over time. Specifically, we first align paragraphs between consecutive disclosures by their similarities. This alignment can be solved as an optimization-based matching problem. Then we identify three types ...

摘要：The coronavirus disease 2019 (COVID-19) pandemic has disrupted normal operating procedures at transplant centers. With the possibility that COVID-19 infection carries an overall 4% mortality rate and potentially a 24% mortality rate among the immunocompromised transplant recipients, many transplant centers considered the possibility of slowing down and even potentially pausing all transplants. Many proposals regarding the need for pausing organ transplants exist; however, much remains unknown....
