摘要：In many scenarios, a fixed capacity is shared flexibly between multiple products. To manage such multiproduct systems, firms need to make two sets of decisions. The first one requires setting an inventory target for each product, and the second requires dynamically allocating the scarce capacity among the products. It is not known how to make these decisions optimally. In this paper, we propose easily implementable policies that have both theoretical and practical appeal. We first suggest simp...

摘要：Under current regulations, red blood cell (RBC) units can be transfused to patients up to 42 days after donation. However, recent studies suggest an association between the age of transfused RBCs and adverse clinical outcomes for their recipients. Therefore, there is an interest in inventory management policies that could reduce the age of transfused RBCs without compromising their availability. In this work, we study the performance of a practical family of threshold-based allocation policies...

摘要：This paper studies how retailers can effectively deliver online and offline information to omnichannel consumers who strategically choose whether to gather information online or offline and whether to buy products online or offline. Information resolves two types of uncertainty: product value uncertainty (i.e., consumers realize valuations when they inspect the product in store, but may end up returning the product when they purchase online) and availability uncertainty (i.e., store visits are...

摘要：An important challenge faced by hotels is how to set their premium room price differential over their standard rooms and how to manage the upsell process. Standby upgrades, where the customer is only charged if the upgrade is available at the time of arrival, is one technique that has become increasingly popular in practice for monetizing the premium room inventory that may otherwise go unused. We develop a model of premium room and standby upgrade pricing under an uncertain market size and ex...

摘要：Fluid teams are commonly used by a variety of organizations to performsimilar and repetitive yet highly critical and knowledge-intensive tasks. Such teams operate for a limited time, after which they dissolve and some of their members may work together again as part of another team. Using a granular data set of 6,206 cardiac surgeries from a private hospital in Europe over seven years, our study offers a new and detailed account of how team familiarity (i.e., shared work experience) influences...

摘要：The bullwhip effect is a phenomenon commonly observed in supply chains. It describes how demand variance amplifies from a downstream site to an upstream site due to demand information distortion. Two different bullwhip effect measures have been used in the literature. Theorists analyze the bullwhip effect based on the information flow (i.e., order and demand information), whereas most empiricists measure it according to the material flow (i.e., shipment and sales data). It is unclear how much ...

摘要：This paper, motivated by a collaboration with a healthcare service provider, focuses on stochastic open-shop service networks with two objectives: more traditional macrolevel measures (such as minimizing total system time or minimizing total number of tardy customers) and the atypical microlevel measure of reducing the incidents of excessively long waits at any workstation within the process. While work-conserving policies are optimal for macrolevel measures, scheduling policies with strategic...

摘要：We study leader-based collective bargaining (LCB), under which a leading buyer (leader) and a following buyer (follower) form an alliance to jointly purchase a common component from a supplier. Although the leader and the follower cooperate in their component purchase, they compete in selling their end products. We first analyze the most common and simple form of LCB, equal price LCB, under which the follower pays to the leader the same wholesale price that the leader obtains from his negotiat...

摘要：Motivated by a collaborative study with one of the most comprehensive ocular imaging programs in the United States, we investigate the underlying three-way trade-off among operational, clinical, and financial considerations in physicians' decisions about ordering imaging tests. Laboratory tests may be processed in parallel and thus have a limited effect on patients' waiting times; imaging tests, by contrast, require patient presence and thus directly influence patients'waiting times. We use a ...

摘要：We study supply function competition among conventional power generators with different levels of flexibility and the impact of intermittent renewable power generation on the competition. Inflexible generators commit production before uncertainties are realized, whereas flexible generators can adjust their production after uncertainties are realized. Both types of generators compete in an electricity market by submitting supply functions to a system operator, who solves a two-stage stochastic ...
