Evaluation of reopening strategies for educational institutions during COVID-19 through agent based simulation

Scientific Reports · 2021 · 35 citations

Many educational institutions have partially or fully closed all operations to cope with the challenges of the ongoing COVID-19 pandemic. In this paper, we explore strategies that such institutions can adopt to conduct safe reopening and resume operations during the pandemic. The research is motivated by the University of Illinois at Urbana-Champaign's (UIUC's) SHIELD program, which is a set of policies and strategies, including rapid saliva-based COVID-19 screening, for ensuring safety of stude…

The Rapid Deployment of a 3D Printed “Latticed” Nasopharyngeal Swab for COVID-19 Testing Made Using Digital Light Synthesis

medRxiv · 2020-05-27 · 16 citations

ABSTRACT The novel coronavirus disease (COVID-19) has caused a pandemic that has disrupted supply chains globally. This black swan event is challenging industries from all sectors of the economy including those industries directly needed to produce items that safeguard us from the disease itself, especially personal protection equipment (N95 masks, face shields) and much needed consumables associated with testing and vaccine delivery (swabs, vials and viral transfer medium). Digital manufacturin…

Manufacturing & Service Operations Management · 2022-08-12 · 9 citations

Problem definition: We investigate variations of the bullwhip effect across foreign subsidiaries and explore how it is affected by various features of foreign subsidiaries. Academic/practical relevance: During the era of global supply chain restructuring, researchers and executives of multinational firms should understand variations of the foreign subsidiary’s bullwhip effect, given that its reduction is a key strategy for coordinating supply chains. Methodology: Our work is based on a balanced…

Sourcing for online marketplaces with demand and price uncertainty

Production and Operations Management · 2023-06-08 · 7 citations

Our paper is motivated by a manufacturer that sells a seasonal product through multiple retailers competing on an online marketplace, such as the Amazon marketplace. Demand and selling price uncertainty are key features of the online marketplace. Sourcing choices are differentiated by cost and available lead times—delaying shortens the lead time which is more expensive but yields more accurate information about future selling price and demand. Thus, ahead of the season, each retailer faces a con…

Detecting and mitigating simultaneous waves of COVID-19 infections

Scientific Reports · 2022-10-06 · 6 citations

The sudden spread of COVID-19 infections in a region can catch its healthcare system by surprise. Can one anticipate such a spread and allow healthcare administrators to prepare for a surge a priori? We posit that the answer lies in distinguishing between two types of waves in epidemic dynamics. The first kind resembles a spatio-temporal diffusion pattern. Its gradual spread allows administrators to marshal resources to combat the epidemic. The second kind is caused by super-spreader events, whi…
