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：Our research focuses on the storage decision in a semi-automated storage system, where the inventory is stored on mobile storage pods. In a typical system, each storage pod carries a mixture of items, and the inventory of each item is spread over multiple storage pods. These pods are transported by robotic drives to stationary stations on the boundary of the storage zone where associates conduct pick or stow operations. The storage decision is to decide to which storage location within the sto...

摘要：Assembly systems, in which various components are sourced from multiple suppliers and assembled into the final product, which is sold to external customers, are found in a variety of industries. In many practical settings, the assembler possesses incomplete information regarding the marginal cost of each supplier. This lack of complete information poses a challenge for the assembler in designing contract mechanisms. In this study, we investigate the assembler's contract design problem by propo...

摘要：It is well-recognized that pre-positioning assets in advance of a natural disaster is important for supporting timely relief provision after a disaster occurs. In addition to preparing for imminent disaster events, humanitarian relief organizations also maintain such asset allocations over time to support future responses to recurrent events such as wildfires or winter storms. This study is motivated by the authors' work with one such relief organization, the American Red Cross in Colorado and...

摘要：This paper studies bargaining in two-sided supply chain networks where manufacturers on the demand side purchase an input from suppliers on the supply side. The manufacturers may have heterogeneous valuations on the input sold by the suppliers. In such a supply chain network, a manufacturer and a supplier must have a business relationship or link to bargain and trade with each other. However, a firm on one side of the supply chain network might not have a business relationship with every firm ...

摘要：Firms in advanced economies are increasingly outsourcing software and technology development as well as other knowledge work to a worldwide supply base. Standard economic and learning models predict that focal firms should outsource either all or none of a particular activity unless extra resources are required during cyclical demand peaks or access is needed to some tightly appropriable intellectual property. However, recent evidence shows that, even when these exceptions do not apply, many f...

摘要：As the severity and frequency of supply chain disruptions increases due to globalization and outsourcing, companies are faced with the challenge of managing correlated disruption risks. However, correctly estimating supplier correlations is difficult and relying on incorrect estimates can be costly. Motivated by these challenges, we consider models for managing disruption risks when suppliers are ambiguously correlated. Our models are based on profit-oriented correlation structures that only r...

摘要：Product launch and pricing decisions in the pharmaceutical industry across different countries are complex. Although introducing a newly developed drug to every country is beneficial to patients worldwide, doing so may have adverse implications for drug developers, such as the emergence of parallel imports. We study a pharmaceutical firm that already introduced a pioneering drug in its home country, where the product is protected by patent rules. The firm decides whether to launch in a second ...

摘要：Researchers have proposed the use of unmanned aerial vehicles (UAVs) in humanitarian relief to search for victims in disaster-affected areas. Once UAVs must search through the entire affected area to find victims, the path-planning operation becomes equivalent to an area coverage problem. In this study, we propose an innovative method for solving such problem based on a Partially Observable Markov Decision Process (POMDP), which considers the observations made from UAVs. The formulation of the...
