摘要：We consider a discrete-time infinite-horizon inventory system with non-stationary demand, full backlogging, and deterministic replenishment lead time. Demand arrives according to a probability distribution conditional on the state of the world that undergoes Markovian transitions over time. But the actual state of the world can only be imperfectly estimated based on past demand data. We model the inventory replenishment problem for this system as a Markov decision process (MDP) with an uncount...

摘要：We study volunteer management at a charity storehouse operated by a large faith-based organization. The storehouse runs entirely on volunteer efforts. We investigate the role of volunteer experience and storehouse congestion in the preparation of orders using a multi-method approach. First, we conduct a field study to explore these relationships and collect data at the level of volunteers' teams. These teams can pair volunteers with either different levels of experience (mixed pairing) or equa...

摘要：We investigate the impact of behavioral ordering on profits under competition. Specifically, we use controlled laboratory experiments to evaluate the differences in profits between a behavioral competitor (where a human places orders), and a management science-driven competitor (where orders are placed according to one of several plausible policies based on existing literature and managerial practice). Unlike the full-information game-theoretic models that assume rational decision-makers, thes...

摘要：We study mechanisms to manage group purchasing among a set of buyers of a given product with a concave purchase cost function. The buyers are cost-sensitive and willing to buy a range of product quantities at different prices. We investigate two types of mechanisms that can be used by a group purchasing organization (GPO): (a) ordering mechanisms where the buyers, without divulging private information, choose their order quantities and pay for them according to a given cost-sharing rule or a f...

摘要：Customer cancellations and no-shows have an important impact on the performance of an airline's revenue management system. In this study, we study airline network revenue management problems with customer cancellations and no-shows, considering two types of demand models: independent-demand and choice-based-demand models. In independent-demand models, the booking request rates for different products are independent of the assortment of products offered by the airline (exogenous), whereas in ch...

摘要：We consider the inventory decision of a retailer facing strategic customers. We develop a behavioral theory that accounts for reference dependence, which makes predictions on how the presence of strategic customers leverages retailer behavior. Specifically, the reference-dependent retailer shall decrease her order quantity when there are more strategic customers in the population. As such, the conventional pull-to-center bias for newsvendor is generalized, since the presence of strategic custo...

摘要：Russell Ackoff's iconoclastic journey through the scholarly world illustrates just how far ahead of his time he was, and how much we all still owe him. His influence was so fundamental that today we accept his once-controversial ideas as taken for granted realities. Every time you try to grasp the complexities of an interdependent system, try to understand the root causes of problems that appear on the surface or try to connect the dots, you are drawing on the groundwork laid by Russ. It would...

摘要：Digital platforms can use application programming interfaces (APIs) to support third-party development of new apps and achieve growth at an unprecedented scale. However, there is also a dilemma between original new development and copycatting by third-party suppliers. Motivated by this tension, we examined how APIs provided by digital platforms may influence two types of third-party new app development: original apps and app copycatting. We also investigated how these influences are dependent ...

摘要：Increasingly, donors that subsidize socially-desirable products in the developing world are shifting from distributing through non-commercial to commercial channels, ceding control of the product price to for-profit intermediaries. This study advises a donor as to how the donor's loss of price control and the level of consumer awareness-defined as the fraction of the consumer population that is informed of the product's benefits-influence the donor's optimal subsidy and utility: First, in shif...

摘要：Empirical studies of service systems have shown that workers exhibit different service rates depending on their assigned workload. In contrast, staffing models typically assume a constant service rate. To address this issue, we model two commonly observed behavioral effects, speedup and slowdown, in a general way that allows us to study their joint impact on service staffing. We fit our behavioral model to a hospital dataset and show that both effects are present across a variety of department...
