摘要：To maintain future supplier competition, manufacturers may support financially distressed suppliers by sourcing from them, even if they are less efficient than competitors, and by procuring larger quantities from them at higher prices. We analyze these strategies in a model in which a manufacturer decides for one of two available suppliers, supplier bankruptcy risk is endogenous, and financial distress can lead to internal or external reorganization. Following bankruptcy, the remaining supplie...

摘要：The extant research on supply chain information sharing under wholesale pricing often assumes a model where the manufacturer can unilaterally set any wholesale price, and the retailer decides retail quantity or price while taking the wholesale price as given. Whereas this model may actually reflect the relative market power in some situations, its implementation misses out on certain win-win opportunities that could arise from information sharing. We propose a new wholesale pricing mechanism t...

摘要：As peer-to-peer sharing platforms emerge in the downstream market, upstream product manufacturers may build their exclusive sharing platform, seeking benefits from the sharing market. To study the profit and welfare implications of the emergence of sharing economy and manufacturer's platform-building strategy, we employ a vertically differentiated duopoly setting and consider three scenarios: no-sharing benchmark, a single third-party platform emerged, and manufacturer-built platform co-existi...

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...
