  摘要：We study mechanisms that encourage manufacturers of health products to build production and distribution capacity. This is important for low- and middle-income country (LMIC) markets where ability to pay is lower and demand risks are greater. Development finance institutions and philanthropies are beginning to utilize new instruments to incentivize manufacturers to build production/distribution capacity for LMIC markets. The goal of this paper is to understand the effectiveness of such mechani...

  摘要：This work addresses the practical anesthesiologist scheduling (AS) problem motivated by the needs of an academic anesthesiology department. The AS problem requires the department to plan and deploy providers to adequately meet clinical demand and institutional protocols of various clinical units over a planning horizon of up to several weeks. A data-driven two-step AS framework is developed by exploiting the historical demand data of anesthesia cases. The first step is a shift design which obt...
• Evaluating the ending-9 pricing strategy along the online shopping funnel AI翻译

  摘要：Ending-9 prices are extremely popular among retailers, leveraging consumers' perception biases. However, despite the popularity of this pricing strategy, understanding of its impact on online retailers is still limited. This is particularly true given the complexity of online retail where consumers need to traverse a shopping funnel, consisting of decisions with shopping cart and purchases. This study aims to answer the following three questions: First, do consumers hold a perception bias towa...
• Managing the security of information systems with partially observable vulnerability AI翻译

  摘要：We consider the security maintenance of information systems where the extent of vulnerability is partially observable. However, the exact extent of the vulnerability can be observed by paying an inspection fee. In each period, the decision-maker needs to take one of three decisions: (i) do nothing, (ii) inspect and implement (fix the vulnerability) if needed, and (iii) directly implement. We prove that the optimal policy follows a threshold structure. For each value of k (the known vulnerabili...
• Provision of helpful review videos: Effects of video characteristics on perceived helpfulness AI翻译

  摘要：With the rapid growth and popularity of YouTube, an increasing number of consumers rely on online product review videos to obtain product-related information. As the provision of online review videos grows and consumers increasingly rely on them for their purchase decisions, understanding factors that contribute to the perceived helpfulness of video reviews becomes critical for video review management. This paper examines how various visual and vocal characteristics of online review videos are...
• Voice-based AI in call center customer service: A natural field experiment AI翻译

  摘要：Voice-based artificial intelligence (AI) systems have been recently deployed to replace traditional interactive voice response (IVR) systems in call center customer service. However, there is little evidence that sheds light on how the implementation of AI systems impacts customer behavior, as well as AI systems' effects on call center customer service performance. By leveraging the proprietary data obtained from a natural field experiment in a large telecommunication company, we examine how t...
• Mixed-model assembly lines with variable takt and open stations AI翻译

  摘要：Industry trends such as product customization, radical innovation, and local production accelerate the adoption of mixed-model assembly lines (MMALs) that can cope with a widening gap between model processing times and true build to order capabilitiy. The existing high work content deviations on such assembly lines stress production planning, especially the assembly line sequencing. Most manufacturers set the launching rate for all assembly line products to a fixed launching rate resulting in ...
• A survey of stochastic inventory models with fixed costs: Optimality of (s, S) and (s, S)-type policies-Continuous-time case AI翻译

  摘要：Fixed costs of ordering items or setting up a production process arise in many real-life scenarios. In their presence, the most widely used ordering policy in the stochastic inventory literature is the (s,S) policy. Optimality of (s,S) policies and (s,S)-type policies have been examined for various inventory models, including those with the inventory level being reviewed in every period or continuously, finite and infinite horizons, discounted-cost and average-cost criteria, backlogging and lo...
• Supply chain short-term financing for responsible production at small and medium-sized enterprises AI翻译

  摘要：Companies have increasingly used supply chain financing instead of bank financing when engaging with financially constrained suppliers. We investigate the effectiveness of different financing mechanisms at supporting supply chain responsibility. We consider a decentralized supply chain where a buyer sources from a financially constrained supplier who borrows from either a bank or the buyer to finance his production. The buyer audits the supplier for responsibility compliance and will refuse to...

  摘要：Our paper is motivated by a manufacturer that sells a seasonal product through multiple retailers competing on an online marketplace, such as the Amazon marketplace. Demand and selling price uncertainty are key features of the online marketplace. Sourcing choices are differentiated by cost and available lead times-delaying shortens the lead time which is more expensive but yields more accurate information about future selling price and demand. Thus, ahead of the season, each retailer faces a c...
