摘要：We consider the pricing/lead-time menu design problem for a monopoly service in which time-sensitive customers have demand on multiple occasions. Customers differ in their demand rates and marginal values (per use). We assume that customers queue for a finite-capacity service under a general pricing structure. Customers choose a plan from the menu to maximize their expected utility. We compare two models: one in which the demand rate is the private information of the customers, and another in ...

摘要：We study dynamic matching in an infinite-horizon stochastic market. Although all agents are potentially compatible with each other, some are hard to match and others are easy to match. Agents prefer to be matched as soon as possible, and matches are formed either bilaterally or indirectly through chains. We adopt an asymptotic approach and compute tight bounds on the limit of waiting time of agents under myopic policies that differ in matching technology and prioritization. We find that when h...

摘要：We consider a periodic-review inventory system of two products with positive replenishment lead times, assuming that downward substitution is allowed and that replenishment is capped. We aim to characterize the structures of the optimal policies for product replenishment and substitution that minimize the expected total discounted cost over a finite horizon. With a Markovian decision programming formulation and an appropriate relaxation of constraints on the substitution quantity, we show that...

摘要：We study network models where flows cannot be split or merged when passing through certain nodes (i.e., for such nodes, each incoming arc flow must be matched to an outgoing arc flow of identical value). This requirement, which we call no-split no-merge (NSNM), appears in railroad applications in which train compositions can only be modified at yards where necessary equipment is available. This combinatorial requirement is crucial when formulating problems occurring in the unit train business....

摘要：Current healthcare reforms advocate significantly to improve the coordination of services around a patient-centric model. With most patient care delivered through outpatient services, the need to coordinate scheduling between different services in a hospital or colocated clinics becomes central to successful reform. Currently, outpatient services require independent appointment decisions, and the coordination is left to the patient. This approach causes several inefficiencies, including an inc...

摘要：Antimicrobial resistance is a significant public health threat. In the United States alone, two million people are infected, and 23,000 die each year from antibiotic-resistant bacterial infections. In many cases, infections are resistant to all but a few remaining drugs. We examine the case in which a single drug remains and solve for the optimal treatment policy for a susceptible-infected-susceptible infectious disease model, incorporating the effects of drug resistance. The problem is formul...

摘要：A fundamental problem faced by firms is that of product line design: given a set of candidate products that may be offered to a collection of customers, what subset of those products should be offered to maximize the profit that is realized when customers make purchases according to their preferences? In this paper, we consider the product line design problem when customers choose according to a first-choice rule and present a new mixed-integer optimization formulation of the problem. We theor...

摘要：Consumers often do not have complete information about the choices they face and, therefore, have to spend time and effort acquiring information. Because information acquisition is costly, consumers trade off the value of better information against its cost and make their final product choices based on imperfect information. We model this decision using the rational inattention approach and describe the rationally inattentive consumer's choice behavior when the consumer faces alternatives with...

摘要：Public health security-achieved by effectively preventing, detecting, and responding to events that affect public health such as bioterrorism, disasters, and naturally occurring disease outbreaks-is a key aspect of national security. However, effective public health preparedness depends on answering largely unanswerable questions. For example: What is the chance of a bioterror attack in the United States in the next five years? What is the chance of an anthrax attack? What might be the locatio...

摘要：We study the dynamic mechanism design problem of a seller who repeatedly auctions independent items over a discrete time horizon to buyers who face a cumulative budget constraint. A driving motivation behind our model is the emergence of real-time bidding markets for online display advertising in which such budgets are prevalent. We assume the seller has a strong form of limited commitment: she commits to the rules of the current auction but cannot commit to those of future auctions. We show t...
