  摘要：We study how to admit and schedule heterogeneous patients by using simple, interpretable, yet effective policies when capacity is scarce, no-show behavior is patient- and time-dependent, service duration and reward are deterministic but patient-dependent, and overtime is costly. Our work is motivated by the aforementioned operational challenges that typically face adopters of new technologies in the healthcare sector. We anchor our study on a partnership with the proton therapy center of Massa...
• The impact of order fulfillment information disclosure on consequences of deceptive counterfeits AI翻译
  作者：Peinkofer, Simone T.; Jin, Yao Henry

  摘要：Online retailers have exposed their consumers to an increase of deceptive counterfeit products provided by third-party marketplace sellers. Although leading online retailers commonly seek to enhance service transparency to consumers by providing fulfillment service information, such as inventory ownership (i.e., sold by) and order fulfillment (i.e., shipped by), their impact remains poorly understood, particularly in the context of when consumers receive deceptive counterfeit products. Drawing...
• Managing medical equipment capacity with early spread of infection in a region AI翻译
  作者：Jain, Apurva; Rayal, Swapnil
  作者单位：University of Washington; University of Washington Seattle
  摘要：We develop a model for a regional decision-maker to analyze the requirement of medical equipment capacity in the early stages of a spread of infections. We use the model to propose and evaluate ways to manage limited equipment capacity. Early-stage infection growth is captured by a stochastic differential equation (SDE) and is part of a two-period community spread and shutdown model. We use the running-maximum process of a geometric Brownian motion to develop a performance metric, probability ...
• Process modularity, supply chain responsiveness, and moderators: The Medecins Sans Frontieres response to the Covid-19 pandemic AI翻译

  摘要：The unprecedented scale of the Covid-19 pandemic has been a challenge for health supply chains around the world. Many international humanitarian organizations have had to ensure the continuity of their already complex development programs, while addressing their supply chain disruptions linked to the pandemic. Process modularity has frequently been advocated as a strategy to mitigate such disruptions, although empirical evidence regarding its impact on supply chain responsiveness and what mode...
• Evaluation Timing with Dynamic Information: Optimization and Heuristic AI翻译

  摘要：Product evaluation is an essential business process, and digital innovation has made it possible for companies to immediately process available information. We develop a model where a company continuously assesses information that follows a doubly stochastic Poisson process with a mean-reverting and stochastic intensity. Accordingly, the company faces a two-dimensional optimal stopping problem in which the company continues to evaluate the product if and only if the product reputation and info...
• Growing user base in the early stage of sharing economy platforms: An integration of competitive repertoire and institutional legitimacy theories AI翻译

  摘要：Sharing economy platforms are pressed to rapidly grow user bases at the early stage by aggressively targeting potential users through competitive actions. Due to the volatile nature of the sharing economy and its disruption to industry norms, these platforms encounter legitimacy challenges that impede user base growth. This paper integrates competitive repertoire and institutional legitimacy theories to develop a research model that explains early-stage user base development in the sharing eco...
• Improving drinking water access and equity in rural Sub-Saharan Africa AI翻译

  摘要：In 2021, access to clean drinking water was still a luxury for millions of people worldwide. Building new water projects, such as handpumps and small piped systems, is the primary operational response by many nongovernmental organizations (NGOs) to bring people their first access to clean water in rural areas of developing countries. Based on knowledge gained from our collaboration with a local NGO and an international NGO and field research in Ethiopia, our research studies where to build new...
• The impact of information on transportation systems with strategic customers AI翻译
  作者：Logothetis, Dimitrios; Economou, Antonis
  作者单位：National & Kapodistrian University of Athens; National & Kapodistrian University of Athens
  摘要：Nowadays, a transportation station has the possibility to provide its potential passengers with information regarding the arrival times of the successively arriving facilities, the congestion in the station and the space availability of future facilities. Such information influences the behavior of the passengers who think strategically and consequently the throughput and the welfare that are generated by the system. In the present work, we consider a general model of a transportation station ...
• Manufacturer encroachment with an e-commerce division AI翻译
  作者：Shi, Siyu; Wang, Chenyu; Cheng, T. C. Edwin; Liu, Shuai
  作者单位：Hong Kong Polytechnic University; Xi'an Jiaotong University
  摘要：Traditionally, manufacturer encroachment is investigated under an integrated organizational structure where online business decisions are made at the whole firm level. However, with the establishment of a specific e-commerce division, the manufacturer has the flexibility to delegate the decision-making of the online business to its e-commerce division to maximize the online revenue under a decentralized structure. We study manufacturer encroachment in a supply chain, where a manufacturer sells...
• Rare is beautiful? Rareness, technology value, and the moderating role of search domain and knowledge maturity AI翻译

  摘要：What makes a technology valuable? Characterizing the value as the degree of impact on subsequent technology development and focusing on the rareness as a composite measure of novelty and conventionality representing the relative position of a technology in a technology space, we advance a theory on the relationship between the rareness and value of a technology as well as the moderating role of search basis in shaping the relationship. We build our theory exploiting the fundamental trade-off b...
