  摘要：Using a large sample of supplier-firm relationships, we develop new measures to operationalize the industrial and geographical concentrations of firms' upstream industries. The developed measures show an upstream industry might be competitive and contain many suppliers (low industrial concentration) and yet be concentrated in a few countries (high geopolitical concentration) or a small geographical area (high geographical concentration), thus leaving the downstream firm vulnerable to geographi...

  摘要：Managerial responses, which represent firms' public replies to online reviews, are commonly employed in customer communications. Using a dataset collected from a leading mobile game app platform in China, this research examines the effect of managerial responses on the review updates of customers who receive them, that is, the direct effect of managerial responses. Platform users can update their reviews, and complete records of review updates are observable, which allows us to utilize variati...

  摘要：The embeddedness of digital platforms in firms to improve industrial accident prevention performance remains a challenge for safety management. A pressing question exists regarding appropriate pathways to improve firm accident prevention performance by leveraging digital platforms. Prior research focuses on individual and organizational factors to prevent industrial accidents while ignoring information technology (IT) from a holistic perspective. Following a socio-technical lens, this study fi...

  摘要：A firm often has multiple sourcing options for its product. Some suppliers may have longer lead times but offer lower prices, whereas reliable suppliers with quick-response capabilities may have higher prices. Purchasing from a cheaper, less reliable supplier can help a firm lower its inventory cost but will expose itself to potential risks. This paper analyzes a supply chain in which a manufacturer can source from a cheaper, less reliable supplier with a long lead time and/or a reliable quick...
• Learning to Balance the Performance and Deterioration of Aging Systems Through Derating AI翻译
  作者：Wang, Jue
  作者单位：Queens University - Canada
  摘要：A common strategy of extending the lifetime of an aging system is to reduce its workload below the normal operating level, a practice known as derating. While derating can slow the deterioration process, it often comes at the expense of reduced performance. Thus, derating involves a trade-off between performance and deterioration. Central to the optimal derating strategy is the relationship between deterioration and workload, also referred to as the pd-relationship. In practice, however, this ...
• On the Valuation and Monetization Roles of the Rolling Intrinsic Policy for Merchant Commodity Storage AI翻译
  作者：Secomandi, Nicola
  作者单位：Rice University
  摘要：Merchants use the rolling intrinsic policy to value commodity storage assets and monetize the values they attribute to these assets. A recent study ascribes to informational inconsistency two discrepancies between its partial monetization findings and the known excellent valuation performance of this method: (i) the rolling intrinsic policy can perform worse than the intrinsic policy and (ii) it appears to be far from optimal. This paper contends that this claim generally confounds information...

  摘要：Prolonged emergency department (ED) length of stay (LOS) is associated with detrimental effects on patient care quality and outcomes. There is evidence that certain groups of patients experience longer LOS based on their gender or race, especially with regard to the part of LOS that is attributable to waiting to be seen by a clinician. This work tackles the patient prioritization and placement aspects of ED operations with the goal of improving throughput and wait time in a fair, equitable way...

  摘要：In the last decade and recently, a wide range of industries and organizations have been subject to IT-related security threats and cybersecurity breaches of varying degrees of severity at an alarming rate. A common practice adopted by organizations to ensure system and network security is to conduct regular audits and assessments. This paper takes on an organizational strategy perspective to analytically model the cost impact of random breaches in various types of networks subject to different...
• Why and How Seru Production Systems Are Responsive and Efficient in Volatile Markets AI翻译

  摘要：Seru production systems have demonstrated excellent rapid response capabilities in both stable and uncertain environments. This study reveals that when compared to the Toyota Production System, the seru production method improves rapid response capabilities by 20% and 50% in stable and uncertain environments, respectively. The underlying reasons for this improvement were unclear, so this became a focus of this paper. Static and dynamic Just-In-Time Organization Systems are used to investigate ...

  摘要：When a platform has limited inventory, it is important to have a variety of products available for each customer while managing the remaining stock. To maximize revenue over the long term, the assortment policy needs to take into account the complex purchasing behavior of customers whose arrival orders and preferences may be unknown. We propose a data-driven approach for dynamic assortment planning that utilizes historical customer arrivals and transaction data. To address the challenge of onl...
