  摘要：In community health programs implemented in underserved areas, community healthcare workers (CHWs) prevent, diagnose, and treat the most common diseases. To ensure continuous in-service training of CHWs, some countries have mentored highly skilled CHWs to become supervisors. Designing a network in such a context implies determining the number of CHWs and supervisors, as well as the routing of the supervisors. This can be defined as a location-routing covering problem (LRCP), a variant of the l...
• Integrated Scheduling and Capacity Planning with Considerations for Patients' Length-of-Stays AI翻译

  摘要：Despite the fact that hospital care is often delivered in successive stages, current healthcare scheduling and capacity planning methods usually treat different hospital units in isolation. To address such a shortcoming, we introduce the first Markov decision process model for scheduling surgical patients on a daily basis, explicitly taking into account patient length-of-stay in hospital after surgeries and inpatient census. By way of a simple and yet innovative variable transformation, we rev...
• A Network-Based Formulation for Scheduling Clinical Rotations AI翻译

  摘要：We investigate the scheduling practices of a medical school that must assign a cohort of students to a series of clinical rotations, while respecting both operational and quality-of-service requirements. Students become available to start clerkship progressively throughout the year and can complete rotations at hospitals in different geographic regions. Each hospital may offer a subset of the clinical rotations, with different start dates, capacities, and cost rates. We propose a novel network...
• Dynamic Monitoring and Control of Irreversible Chronic Diseases with Application to Glaucoma AI翻译

  摘要：To manage chronic disease patients effectively, clinicians must know (i) how to monitor each patient (i.e., when to schedule the next visit and which tests to take), and (ii) how to control the disease (i.e., what levels of controllable risk factors will sufficiently slow progression). Our research addresses these questions simultaneously and provides the optimal solution to a novel linear quadratic Gaussian state space model. For the objective of minimizing the relative change in state over t...
• First-Price Split-Award Auctions in Procurement Markets with Economies of Scale: An Experimental Study AI翻译

  摘要：We experimentally study first-price split-award auction formats as they can be found in procurement markets where suppliers have economies of scale. Our analysis includes sequential and combinatorial auctions, which allow for bids on the package of two shares and single shares. We derive equilibrium predictions as hypotheses for bidder behavior in our laboratory experiments. These equilibrium predictions help explain important patterns in our experimental results. The combinatorial first-price...
• Risk Pooling, Supply Chain Hierarchy, and Analysts' Forecasts AI翻译

  摘要：We investigate whether a firm's risk pooling affects its analysts' forecasts, specifically in terms of forecast accuracy and their use of public vs. private information, and how risk pooling interacts with a firm's position in the supply chain to affect analysts' forecasts. We use a social network analysis method to operationalize risk pooling and supply chain hierarchy, and find that risk pooling significantly reduces analysts' forecast errors and increases (decreases) their use of public (pr...

• Analyzing the Proposed Reconfiguration of Accident-and-Emergency Facilities in England AI翻译

  摘要：The Keogh Report of 2013 proposed a major reconfiguration of the accident and emergency (A&E) system under National Health Service (NHS) England to improve service. The proposed reconfiguration includes centralized facilities with multiple specialties as well as small local minor-injury facilities. We use stylized queuing models to analyze cost and service implications of the proposed reconfiguration. We find that increasing numbers of specialty patients that require admission to hospital make...

  摘要：Motivated by the ever-growing complexity of projects and the consistent trend of outsourcing of individual tasks or components, we study the contract-design problem faced by a firm (or organization) for executing a project consisting of multiple tasks, each of which is performed by an individual contractor whose efforts (work-rates) are not observable. While the contractors incur costs continuously during the course of their tasks, the firm realizes its reward or revenue only when the entire p...

  摘要：There is extensive academic research examining why firms adopt environmental management practices (EMPs), reflecting an increasing focus on firm environmental activity in research and practice. However, there is little understanding of why firms vary within and across industries in the number of EMPs they adopt (EMP adoption). In this study, we seek to identify the sources of variation and quantify the relative importance of each source. Using Hierarchical Linear Modeling (HLM) and a 12-year p...
