摘要：Facilitated by information technology and online platforms, group service has emerged in many service systems, such as one-to-many tour guide service, one-to-many tutoring courses and one-to-many medical diagnosis. We consider a service provider offering both group service and individual service and model it as a single-server queue in which customers with heterogeneous waiting costs make both joining/balking and group/individual service decisions. We solve the private provider's service assor...

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：For patients diagnosed with a chronic condition, appropriately timing treatment is critically important. Many conditions, such as age-related macular degeneration (AMD), have a maximum safe treatment interval (MSTI) in which treatment is required to prevent disease progression. We introduce a Markov decision process (MDP) with an ordinal action space as a way to quickly and safely identify the MSTI for an individual patient. The MDP's ordinal action space allows users to update the expected ou...

摘要：Recent attention to labor trafficking as an underaddressed part of human trafficking has added urgency to the need to improve corporate supply chain actions and policies. Through a cross-case analysis of data from the agricultural sector in the United States, this paper seeks to understand labor trafficking operations through a socio-technic systems theory lens and contributes to prior literature on labor trafficking in three important ways. First, we utilize a cross-case approach to explore l...

摘要：This study examines the impact of a replenishment recommendation system on inventory management in convenience stores. We collaborate with a convenience store chain to implement the system in some locations while leaving others unchanged. We find that the introduction of the system increases reorder points and reduces order size, leading to a 2.9% improvement in service levels without requiring additional inventory and without negatively affecting sales or revenue. Additionally, it reduces man...

摘要：Consider a public healthcare system consisting of a hospital, a mobile clinic (MC), and a population of potential patients. The government is concerned about the system's healthcare spending and the population's health outcomes. It decides the frequency and capacity of the MC service to maximize the social welfare that consists of two terms: the system's long-run average healthcare cost and the population's average quality-adjusted life year (QALY). We characterize the population's natural dis...

摘要：Online reviews play an important role in explaining product demand. Our study extends the literature by assessing how arousal (the intensity of the emotion), an important dimension of emotion, and valence (the positiveness of the emotion) can affect product demand across different customer groups. Specifically, regarding product demand from new customers, consumers infer service quality from expressed valence and arousal from other consumers' reviews. Regarding product demand from returning cu...

摘要：We investigate how volume flexibility, defined by a sourcing cost premium beyond a base capacity, at a local responsive supplier impacts the decision to reshore supply. The buyer also has access to a remote supplier that is cheaper with no restrictions on volume flexibility. We show that with unit lead time difference between both suppliers, the optimal dual sourcing policy is a modified dual base-stock policy with three base-stock levels S 1 f, S 2 f, and S s. The replenishment orders are gen...

摘要：Motivated by the emerging mixed autonomous paradigm in cobotic order picking operations, we investigate the optimal information design to navigate human workers (HWs) who cooperate with autonomous mobile robots (AMRs) within an intralogistics system. We incorporate asymmetric information between AMRs and HWs in a routing game where connected AMRs are informed of the congestion state while HWs rely on information provided by the system. The system designs a communication policy aiming to naviga...

摘要：We explore retail supply chains in emerging markets in which a manufacturer can reach consumers by selling its product through very small independent stores (nanostores) and/or through a supermarket. Nanostores offer consumers the advantage of proximity, but supermarkets offer the advantage of bulk buying. We explore the competition between the supermarket and nanostores and examine the manufacturer's role in shaping the retail market structure for its product through wholesale price contracts...
