摘要：We consider a supply chain where multiple suppliers and a manufacturer contribute to the assembly of a product (through providing components or labor). The product fails if any of its components (or elements of work) fails, but finding the faulty component can be prohibitively difficult. We study group warranty contracts for the manufacturer to induce suppliers to improve their quality levels. When information is symmetric and the manufacturer can contract on his own quality level, we show tha...

摘要：Firms use social media as a great marketing tool and a convenient platform to deliver customer service. However, due to its public and social nature, social media tends to amplify a brand's successes as well as failures. Reluctant to subject their customer service to public scrutiny, firms are increasingly turning to private messaging on their social media channels for customer service conversations, which amounts to a reincarnation of traditional customer service in the social media era. None...

摘要：This article studies an appointment scheduling problem where a service provider dynamically receives appointment requests from a random number of customers. By leveraging the randomness of the number of potential customers, we develop a nonsequential appointment scheduling policy as an alternative to the conventional first-come-first-served (FCFS) policy. This allows for more flexibility in managing appointment scheduling. To calculate the optimal policy, we develop a branch-and-bound algorith...

摘要：Cloud Kitchens are delivery-only facilities that house multiple restaurants. Food-delivery platforms operate such kitchens to exploit two advantages: (a) Location advantage, arising due to a cloud-kitchen's central location-this enables lower delivery times to customers. (b) Consolidation advantage, which accrues when multiple restaurants choose to co-locate at the cloud kitchen-this enables the platform to use a common pool of delivery drivers, thereby reducing costs. However, a cloud-kitchen...

摘要：Past research in operations management and marketing on inventory levels and product variety has predominantly focused on their effects on brand performance indicators, such as sales and market share while overlooking the influence on consumers' perceptions of brands. Brand perceptions, encompassing reputation, quality, credibility, and emotional associations, go beyond typical revenue metrics and offer foresight into a brand's future performance. Hence, understanding the effects of inventory ...

摘要：In biopharmaceutical manufacturing, fermentation processes play a critical role in productivity and profit. A fermentation process uses living cells with complex biological mechanisms, leading to high variability in the process outputs, namely, the protein and impurity levels. By building on the biological mechanisms of protein and impurity growth, we introduce a stochastic model to characterize the accumulation of the protein and impurity levels in the fermentation process. However, a common ...

摘要：Live streaming has emerged as an innovative means for content providers (broadcasters) to monetize their content in real time under pay-what-you-want pricing. In a typical live stream, consumers (viewers) watch the content and decide whether and how much to tip the broadcaster in the form of virtual gifts that have been purchased with real money. Unlike offline contexts where payment is often nontransparent, both payment activities and sender identities are transparent or publicly observable i...

摘要：In the dynamic e-commerce environment, social commerce has emerged as a revolutionary force, transforming how consumers interact and transact online. This paper investigates the differences in customers' search and purchase patterns between a prominent online retailer's burgeoning social commerce channel, the WeChat mini-program, and its native mobile app. We analyze the customers' entire journey through a sequential search model that encapsulates decisions from channel selection to product se...

摘要：Once autonomous vehicles (AVs) are deployed for ride-hailing platforms, human drivers will compete with AVs until AV costs decrease enough to eliminate human drivers entirely. We examine a ride-hailing platform's strategy to recruit human drivers while operating a private AV fleet. Using a game-theoretic model, we analyze how the platform sets the human-driver wage and the size of its AV fleet. We show that setting a higher wage can surprisingly lead to less human-driver participation. Moreove...

摘要：In a globalized economy, companies face a range of challenges and opportunities related to relocating production activities to a new country. Relocation can yield significant cost savings and other benefits, but there are also risks including potential damage to the brand image. Thus, firms need to carefully evaluate when to relocate and when to stop production in a particular location. We formulate an optimal control model and derive analytical as well as numerical results to provide insights...
