  摘要：In business markets, sales from customers are often jointly determined by multiple roles, yet firms struggle to quantify individual contribution of each role and the synergies among them. This study applies a value-partitioning approach to separate the sales contributions of customer-focused outside (OS) representatives (reps) and operations-focused inside (IS) reps, and their synergistic effects. It leverages variations in OS-IS combinations to generate individual-level value-added metrics, a...
• Lead Time Prediction for Inventory Optimization With Machine Learning AI翻译

  摘要：Modern decision-support applications build on planning parameters such as lead time, price, yield, etc., which are maintained as master data. The accuracy of master data significantly influences the viability of such applications. However, the maintenance of master data is considered a tedious and error-prone task. In this study, we explore the effectiveness of machine learning techniques to improve the accuracy of plan lead times. We apply both unsupervised and supervised learning methods for...
• Quality, Necessity, or Accessibility? Impact of Dockless Bike Sharing on Ineffective Use of Medical Resources AI翻译

  摘要：In recent years, patients have increasing autonomy in medical decision-making. With great autonomy in selecting medical institutions, patients with low-risk diseases may opt for treatment in prestigious hospitals, which limits the access of patients with high-risk diseases to these hospitals. Moreover, due to limited medical knowledge and a fear of uncertainty regarding diseases, patients with greater medical autonomy may request various unnecessary medical tests to alleviate their health-rela...

  摘要：Dynamic treatment regimes improve health outcomes by tailoring each treatment to a patient's evolving condition, but they also allow providers to learn and game the system over time. How should insurers pay? We study this new class of reimbursement problems, where the provider can privately learn and manipulate the progression of the patient's condition. (i) We characterize the optimal payment policy: it internalizes two intertemporal effects of each treatment, and rewards provider honesty wit...
• Impact of Dynamic Operations Complexity on Performance: The Role of National Culture AI翻译

  摘要：We build on the national culture, complex adaptive systems, and operations complexity literature to develop hypotheses about the moderating role of national culture on the negative relationship between dynamic operations culture and operational complexity. Monthly performance data were collected from 179 plants in a multinational corporation's global plant network that spans all national culture clusters. We use random effects time series modeling to incorporate the transitory nature of this r...
• Impacts of Strategic Consumers and Direct Channel on Supply Chain Contracting AI翻译

  摘要：We examine the impacts of strategic consumers and direct channel on the manufacturer's choice between static and dynamic contracts. We consider two scenarios: One in which the manufacturer sells through a single retailer, and the other in which it sells through two different retailers sequentially. In each scenario, the retailer(s) sets the retail prices, which the manufacturer's direct channel matches, while consumers may time their purchases. We derive the subgame perfect Nash equilibrium. W...
• Measuring Consistency in Service Delivery: Examining the Effect of Process Standardization on Hospital Performance AI翻译

  摘要：Healthcare services provided to patients with similar medical conditions are known to vary. Standardization of healthcare delivery is a relatively new, yet hotly debated approach to address clinical variations. Previous research on process standardization in health service delivery has focused on measuring adherence to established protocols available only for a limited set of medical conditions. We create an alternate construct that quantifies process standardization measured in terms of consi...
• The Value of Flexibility in Robust Supply Chain Network Design AI翻译

  摘要：A supply chain network design problem (SCNDP) involves making long-term, irreversible strategic decisions whose cost efficiency depends on effectively leveraging flexibility and demand information. After analyzing the interaction of these factors, we propose five distinct policies for addressing the SCNDP. Starting with a localized production model where demand is satisfied locally, the study extends to scenarios where production capacity at one location serves other nodes (Policy II). Further...
• Enterprise Social Media Platform Design and Knowledge Worker Productivity AI翻译

  摘要：Companies often use enterprise social media platforms (ESMPs) to promote help among knowledge workers and to improve their productivity. However, many ESMP implementations have had mixed success due to employee reluctance to engage with the platform (e.g. by requesting and giving help). Prominent ESMPs have added varying design features to promote help, but the effectiveness of individual design features remains unclear. Our paper studies this using a laboratory experiment that consists of two...
• Equitable Workload Allocation in Vehicle Routing Problem With Heterogeneous Drivers AI翻译

  摘要：In the private logistics service sector, considerations of fairness among service agents are relatively new but are gaining importance due to public and governmental pressures to improve equity in workload allocation among internal stakeholders, such as the service personnel. Fairness becomes more complex in settings with a heterogeneous workforce due to inherent worker differences. In this study, we present an equitable workload allocation model for the vehicle routing problem with heterogene...
