摘要：We combine insights from information processing theory (IPT), supply chain resilience literature, and collaboration with a leading supply chain planning technology provider to study the effects of excess inventory (a buffering tactic) and usage of supply chain planning systems (SCPSs) (a bridging technology) on supply chain resilience. Utilizing the exogenous disruptions caused by the COVID-19 pandemic as the setting for quasi-natural experiments, we compare profit impact and time-to-recover a...

摘要：In reusable resources like vehicle sharing, city parking, and hotel services, resource units are used by consecutive customers for a stochastic usage time and are made available for future customers upon return. We model such reusable resources as Erlang loss systems, where customers who find all units occupied are blocked. Customers are rational decision-makers, and their willingness to join the system depends on factors such as price, time limits, service value, and resource availability. Wh...

摘要：Prior to the Internet, many industries catering to mass audiences, particularly entertainment industries, tended to have very skewed sales distributions with most sales volume accruing to a small share of products (titles) generally known by terms such as blockbusters. The long tail hypothesis claims that increased Internet usage will weaken the dominance of blockbusters in these industries, so that the large number of obscure products, in aggregate, will become an important, perhaps primary, ...

摘要：This paper investigates how a manufacturer's internal sourcing capability and government regulation influence the supplier's distribution strategy and the manufacturer's sourcing and capability investment decisions. We consider a supply chain consisting of a supplier that produces a critical component, an independent manufacturer that also has the capability to produce the component in-house, and a dependent manufacturer without such capability. We first consider a scenario in which the suppli...

摘要：Queue-based rules for allocating scarce goods are widely utilized in booking systems due to their perceived efficiency. However, empirical investigations into the externalities and opportunity costs of queuing in multitasking scenarios are limited. This paper reports on two laboratory experiments that compare a queue-based rule with a lottery-based rule by quantifying their respective efficiency losses. Our findings indicate that while the queue-based rule demonstrates superior allocative effi...

摘要：When a competitor enters a market, incumbent retail stores often adjust their product variety to avoid sales loss. However, no empirical evidence has been provided in the literature to justify the value of such product variety adjustments after a rival's entry. One difficulty is that the change in consumer demand due to rival's entry and changes in product variety simultaneously affect incumbents' sales. When changes in sales at incumbent stores are observed after rivals' entries, it is unclea...

摘要：The attended home healthcare (AHH) industry is experiencing rapid growth due to the rising demand from an aging population and the potential benefits of alleviating pressures on traditional healthcare resources. However, ensuring timely one-on-one AHH services for homebound patients remains a challenge because of cascading delays arising from uncertainties in travel and service times. To address this issue in last-mile homecare delivery, we develop a systematic cascading delay mitigation strat...

摘要：The proliferation of fake news, more recently multimodal fake news, poses a significant threat to individuals, organizations, and society. While online social media platforms have employed automated methods to combat fake news, they face two notable challenges: the scarcity of labeled data and the diversity of news domains. To enhance the effectiveness and efficiency of online platforms in mitigating the spread of fake news, this study proposes MT-GPD (multimodal deep transfer learning with ga...

摘要：We study the design of a novel, flexible revenue-sharing contract between a platform and an app developer (or other digital content provider) when the parties hold heterogeneous beliefs with regard to the future income. The current contracts adopted by platforms in reality invoke a policy of two or three commission levels based on historical revenue data. We design a contract in which the commission is a continuous function of the revenue generated by the app or other digital content within th...

摘要：In this article, we investigate the problem of sequencing data requests for linear devices, such as magnetic tapes, to minimize response time in cold-storage solutions for archival data. Tapes are the technology of choice for long-term storage due to their reliability, low costs, security, and significant energy savings. However, physical limitations on tape pose challenges to policy implementation, which must be scalable on low-power hardware. We provide a theoretical and numerical analysis o...
