摘要：The combination of insufficient funds and limited information regarding the demand in regions of desperate need presents a great challenge to many humanitarian organizations. This study examines how a humanitarian organization can minimize the expected shortage in delivering relief aid to regions of need, either though surface or air transportation, in the presence of demand uncertainty with a budget constraint. The study makes four contributions. First, we show that when there is reserved sup...

摘要：Enabled by the advances in information technology (IT), many supply chain partners have adopted the practice of vendor-managed inventory (VMI) to improve operations efficiency. While the IT investment for VMI implementation can be significant, the benefits of VMI to different supply chain members are not obvious based on anecdotal evidences and empirical studies. This paper studies the effects of VMI on a supply chain consisting of one manufacturer and one retailer to shed light on when an IT ...

摘要：Breast cancer, the leading cause of cancer death for women, can be detected at earlier stages through mammography screening. Therefore, most developed countries implemented population-based mammography screening programs. However, cost of mammography and limited resources in terms of number of trained personnel and diagnostic machines prevent mammography screening to be adopted by many other countries. In fact, even in resource-rich countries, there is a growing concern about cost of mammograp...

摘要：Cloud services have grown rapidly in recent years as a new form of service, but there exists scant research on the competition and service offering strategies of cloud service providers. We study these strategic choices by considering a setting where an incumbent cloud service provider may offer two service classes (premium and standard) and an entrant provider may offer the standard service. We analyze two competitive strategies the incumbent provider: (a) deterring competitor entry, and (b) ...

摘要：The emerging click-based pricing models for Internet advertising provide the firm with two possible decision processes to manage an advertising campaign, namely, spending-based and traffic-based. The spending-based process starts with the spending budget and determines the traffic accordingly, whereas the traffic-based process starts with a target level of traffic and determines the spending budget accordingly. We consider a duopoly where two electronic retailing firmsthat compete for customer...

摘要：In this study, we propose a stylized Cournot competition model under asymmetric market information and study the formation of producers' informational coalitions. We offer guidance towards how the information service operations can improve the producers' welfare. Our results shed interesting light on farmer producer organizations (FPOs) in their efforts to link farmers in developing economies by integrating market information. To be specific, by focusing on Nash equilibria wherein producers ma...

摘要：Mechanical Turk (MTurk), an online labor market run by Amazon, provides a web platform for conducting behavioral experiments; the site offers immediate and inexpensive access to a large subject pool. In this study, we review recent research about using MTurk for behavioral experiments and test the validity of using MTurk for experiments in behavioral operations management. We recruited subjects from MTurk to replicate the inventory management experiment from Bolton and Katok (), as well as the...

摘要：We investigate how recycling can be a strategic source of supply in the presence of a changing supply market. This research is inspired by the metal cutting tools industry, where challenges regarding a key raw material present an opportunity for the manufacturers to create an alternative supply source by recycling. In this study, there is a virgin material market that supplies two manufacturers differentiated in their recycling ability. The problem is formulated as a game, where the manufactur...

摘要：In hospitals, Step Down Units (SDUs) provide an intermediate level of care between the Intensive Care Units (ICUs) and the general medical-surgical wards. Because SDUs are less richly staffed than ICUs, they are less costly to operate; however, they also are unable to provide the level of care required by the sickest patients. There is an ongoing debate in the medical community as to whether and how SDUs should be used. On one hand, an SDU alleviates ICU congestion by providing a safe environm...

摘要：We study the impact of customer information portability on market competition in customer-centric, technology-intensive service industries. By allowing customer information to be transferrable among service providers, portability in theory may help reduce switching costs and promote competition. Yet the actual consequences are unclear. To investigate this issue, we focus on the global wireless industry, and examine the impact of mobile number portability (MNP) policy. We construct a duopoly mo...
