  摘要：Patients admitted to a hospital's intensive care unit (ICU) often endure prolonged boarding within the ICU following receipt of care, unnecessarily occupying a critical care bed, and thereby delaying admission for other incoming patients due to bed shortage. Using patient-level data over two years at two major academic medical centers, we estimate the impact of ICU and ward occupancy levels on ICU length of stay (LOS), and test whether simultaneous surge occupancy in both areas impacts overall...

  摘要：Based on the resource-based view (RBV) and the transaction cost economics (TCE) theories, we study the impact of IT capability on the performance of port supply chain using an IT-enabled transaction cost frontier model where the IT capability is modeled as a unique production input and as an endogenous transaction attribute as well. By examining the optimal levels of IT capability for different port systems from the viewpoint of production cost and transaction cost, we find theoretical evidenc...
• Increasing Supply Chain Robustness through Process Flexibility and Inventory AI翻译

  摘要：We study a hybrid strategy that uses both process flexibility and finished goods inventory for supply chain risk mitigation. The interplay between process flexibility and inventory is modeled as a two-stage robust optimization problem. In the first stage, the firm allocates inventory before disruption happens; in the second stage, after a disruption happens, the firm determines production quantities at each plant to minimize demand loss. Our robust optimization model can be solved efficiently ...

  摘要：In recent years, many urban areas have established healthcare coalitions (HCCs) composed of autonomous (and often competing) hospitals, with the goal of improving emergency preparedness and response. We study the role of such coalitions in the specific context of response to multiple-casualty incidents in an urban setting, where on-scene responders must determine how to send casualties to medical facilities. A key function in incident response is multi-agency coordination. When this coordinati...

• Utilizing Public Betas and Free Trials to Launch a Software Product AI翻译

  摘要：Many software product firms release a public beta prior to launching its product. Public betas are adopted by innovator consumers and firms use free feedback from these consumers to improve the quality of the product. While trying out the public beta, innovators also learn their product preferences accurately. In addition, opinions expressed by the innovators about the software on public forums like blogs, etc., can introduce a perception bias about the product's quality among the imitator con...
• Introduction to the Special Issue on Perspectives onBig Data AI翻译

  摘要：Big data has the potential of offering valuable insights into the way organizations function, and it is changing theway organizations make decisions. Nine invited essays provide a wide range of perspectives on the role of big data in customer-driven supply chains, healthcare operations, retail operations, demand planning and manufacturing, environmental and social issues, humanitarian operations, agriculture supply chains, and service operations. Decision makers should have clean, valid, and r...
• Retailer Information Sharing with Supplier Encroachment AI翻译

  摘要：This study investigates a retailer's incentive for sharing private demand information with a supplier who may encroach the retail channel by imposing a fixed entry cost. Although conventional wisdom suggests that a retailer should withhold her private demand observations to maintain an information advantage over the supplier, we obtain a different conclusion by demonstrating that the retailer may prefer to voluntarily share the demand information in anticipation of supplier encroachment. The i...
• The Impact of Consumer Fairness Seeking on Distribution Channel Selection: Direct Selling vs. Agent Selling AI翻译

  摘要：Consumers seek for not only base functionalities of products they buy but also fairness in transactions. In this work, we investigate how such fairness-seeking behavior affects a manufacturer's distribution channel structure selection. Specifically, the manufacturer can sell the product directly to consumers (named direct selling) or via a middleman retailer (named agent selling). The manufacturer then decides which distribution channel to adopt with an aim to maximize his profit. Under a news...
• A Game Between a Terrorist and a Passive Defender AI翻译

  摘要：In the last two decades, terrorism has become a major issue around the world. We analyze a continuous conflict between a terrorist (Terrorist) and a passive defender (Defender). Defender is passive because her actions can influence only the costs (damages) when Terrorist attacks. We focus on high-trajectory fire attacks and passive responses to them in the conflict between Israel and the various terrorist groups in the Gaza Strip in accordance with scientific principles. We first consider thre...
