Supply Chain Resiliency and the Need for Stress Tests<\/span><\/h3>\n

As hospitalizations decrease and vaccinations increase, some see the end of the COVID-19 pandemic somewhere on the horizon. With that, many of us in the data science community are analyzing \u201clessons learned\u201d from the pandemic to better prepare and more efficiently and effectively respond to the next disaster. At the center of this discussion must be how to fix our supply chains to prevent disruptions where possible and to identify \u2013 before a disaster occurs \u2013 where vulnerabilities exist.<\/span><\/p>\n

Bio<\/span><\/h4>\n

David Simchi-Levi is a Professor of Engineering Systems at MIT and serves as the head of the MIT Data Science Lab. He is considered one of the premier thought leaders in supply chain management and business analytics. His Ph.D. students have accepted faculty positions in leading academic institutes including U. of California Berkeley, Carnegie Mellon U., Columbia U., Duke U., Georgia Tech, Harvard U., U. of Illinois Urbana-Champaign, U. of Michigan, Purdue U. and Virginia Tech.\u00a0<\/span><\/p>\n

Professor Simchi-Levi is the current Editor-in-Chief of Management Science<\/em>, one of the two flagship journals of INFORMS.

Racial and Ethnic Disparities in Access to Behavioral Health Services Among Medicaid Enrollees during the COVID Pandemic: Did Telehealth Level the Playing Field?
<\/span><\/h3>\n

The COVID-19 pandemic has created unprecedented challenges for people with behavior health (BH) conditions and may widen the existing disparities in access to and receiving of BH services. This study, conducted by Binh Nguyen, Qinli Ma, Eric Bailly, Anthony LoSasso, and Winnie Chi assessed racial disparities in access and utilization of BH services and the changes during the pandemic among Medicaid population.<\/span><\/p>\n

Bio<\/span><\/h4>\n

Anthony Lo Sasso is Professor and Driehaus Fellow in the Economics Department at DePaul University in Chicago. His research spans several dimensions of health and labor economics, health policy, and health services and outcomes research. He is keenly interested in how government policies affect private sector decisions. After receiving an Agency for Healthcare Research and Quality (AHRQ) 5-year Independent Scientist Award entitled \u201cWorkplace Health Benefits and Employee Health,\u201d his research explored the impact of the State Children\u2019s Health Insurance Program on insurance among children and the extent to which public coverage may have \u201ccrowded out\u201d private coverage of children; how community rating provisions in state health insurance markets affect health insurance coverage; and how the availability of safety net health care services affects the willingness of firms to offer health insurance and the willingness of employees to take-up health insurance when it is offered.<\/span><\/p>\n

An area of particular interest for Lo Sasso is the effects of health insurance benefit design on health care utilization and health outcomes. This work includes an AHRQ-funded research grant to study so-called narrow network insurance plans; a National Institute of Mental Health (NIMH) funded study to examine the impact of an expansion of mental health benefits on cost and quality of care at a large manufacturing firm; and ongoing work examining the effects of high deductible health insurance on health care use. Additionally, he served as co-investigator on an NIH-funded study examining the effects of corporate wellness programs on use of preventive services and health outcomes.<\/span><\/p>\n

Until recently (2012-2019), Lo Sasso served as the Executive Director of the American Society of Health Economists (ASHEcon). With training in labor and health economics and extensive experience studying the effects of insurance in both the private and public sectors, he is a nationally recognized leader in the field.

Using Data Science, Machine Learning and Decision Analytics in Transplant Policies\u00a0<\/strong><\/h4>\n

This presentation includes examples of several yearlong efforts in the use of operations engineering approaches to improving transplant policies in the areas of kidney and liver allocation, distribution and reducing kidney discards. This work involved real-life data analysis using classical and newer statistical and machine learning tools. It also involved developing optimization models and simulation. Finally, one of the projects influenced liver and subsequently kidney allocation policy changes for equitable distribution of deceased donor kidneys and livers. Time permitting results will also be discussed based on a second related project on reducing kidney discards in the national allocation system.<\/p>\n

Safely Seating Fans, Using Combinatorial Optimization<\/h3>\n

During the COVID-19 pandemic in 2020, venue managers realized that they were going to have to figure out how to safely seat fans in stadiums, arenas, and theaters. While it is relatively simple to produce a heuristic seating plan that keeps groups who live together (i.e. immediate families or roommates) separated by some distance, such plans are likely not optimal in terms of maximizing attendance, revenue, or other quantities of interest.\u00a0 Using combinatorial optimization, the presenter, along with a colleague and former student, developed a model for use at the University of Notre Dame.\u00a0 It was later commercialized and used by others, including professional sports teams. The Software as a Service (SaaS) offering uses an R Shiny front-end with an open-source solver, and is based in an Amazon Web Services (AWS) Elastic Cloud Compute (EC2) instance.<\/p>\n

Operations Research Applications for Hospital Capacity Planning and Management during COVID-19 Pandemic, and Lessons for the Post-Pandemic Period<\/strong>
<\/span><\/h3>\n

Rapid deployment of Operations Research (OR) techniques played a key role during the earlier phases of the COVID-19 pandemic for capacity management and capacity reservation decisions at hospitals. Analytical modeling and analytical thinking proved critical in predicting hospital census of COVID positive patients. Lessons learned that are applicable for the post-pandemic period include the challenge of developing models with incomplete and unknown information, and the tradeoff between simpler yet accurately parameterized models vs. complex models with questionable parametric values. Another lesson learnt is the unique contribution OR folks can bring to an analytics-heavy multidisciplinary team comprised of epidemiologists, biostatisticians, and healthcare practitioners.<\/p>\n

Network Effects on Online Retail-based Platforms<\/strong><\/em><\/h3>\n

Online retail-based platforms such as Alibaba and Google Shopping are partnership networks that use the Internet to bring retailers and customers together. One of the benefits of the online platforms is network effects, in which customers can purchase from multiple retailers, giving rise to a unique network. This study explores how online platforms and retailers benefit from network effects. The implications are for the managers of online platforms who decide strategies for recruiting, managing, promoting retailers in the network.<\/p>\n

Scrap Reduction using Mixed Integer Linear Programming<\/em><\/strong><\/h3>\n

Nobelus supplies its clients with laminate films for printing and packaging applications. They cut big film rolls into different sizes as ordered by customers. This project upgrades its manual pattern planning operation to an automatic, algorithmic, OR-based one. We create a 2D cutting stock model and a column generation algorithm to minimize scrapped material. With waste being reduced by 50%, Nobelus can increase its profit margin, reduce order lead time, respond to demand uncertainty quickly, lower its environmental impact, and sustain its growth during the covid-19 pandemic. The solution can be scaled and applicable to paper, wood, packaging, and other manufacturing industries.<\/p>\n
