  • From the Editors' Desk
    From the Editors’ Desk: FALL 2015 Xiaopeng Li, University of South Florida, [email protected], Sandra Eksioglu, Clemson University, [email protected] Kevin N Crook, BNSF, [email protected], Xuesong Zhou, Arizona State University, [email protected] Railroads play an important role in countries around the world. Railroads are efficient, safe, and environmentally friendly. Despite their many advantages, like any industry, railroads face many challenges – e.g., competition from other railroads, competition from other transportation modes, technological advances, increased customer expectations, increased shareholder expectations, governmental regulations, and a general drive for continual improvement. The Railroad Application Section (RAS) of INFORMS brings industry experts, academic researchers, and OR/Analytics practitioners together to find creative solutions to meet the challenges facing the railroad industry. The RAS meetings at the INFORMS annual meeting play an important role in meeting RAS’s objectives. The RAS meetings will include: 13 sessions planned to shared findings and insights on a variety of topics the Problem-Solving Competition presentations of the three finalists (from the 37 submissions) the Student Paper Competition finalists’ presentations a roundtable discussion about railroad operations efficiency and recovery. Thank you to all those who have helped with this year’s conference. We encourage all of you to consider taking an active role in RAS next year by running for office, chairing a session, presenting in a session, helping with the problem competition, or helping with the student paper compe- tition, etc. RAS is only as good as we make it. We want to congratulate Clark Cheng for being awarded the 2015 RAS Distinguished Member award for his continued contributions to RAS.

  • Report of the Activities of the Center for Applied Optimization (CAO) for the Period: Fall 2012- End of Fall 2017
    Report of the Activities of the Center for Applied Optimization (CAO) for the period: Fall 2012- end of Fall 2017 Director: Panos M. Pardalos http://www.ise.ufl.edu/cao/ http://www.ise.ufl.edu/pardalos/ 1. Overview The Center for Applied Optimization at the University of Florida is an interdisciplinary center which encourages joint research and applied projects among faculty from engineering, medicine, mathematics and business. It also encourages increased awareness of the rapidly growing field of optimization through publications, conferences, joint research and student exchange. It was founded in September 1992. During the last five years, we have collaborated with other university centers, institutes, and large projects. We are part of a larger PRISMA-P (Precision and Intelligent Systems in Medicine) project, funded by NIH, since its inception from 2013. We are part of a newly funded NSF IUCRC (Industry and University Cooperative Research Center) program at the University of Florida: Center for Big Learning, whose goal is to push further the research, tech transfer and application of deep learning technologies. We have been collaborating with the UF Informatics Institute since 2016. We co- organized the Conference on Computational Biomedicine for the past three years (CBM 2016, CBM 2017 & CBM 2018). We are collaborating with the UF Brain Institute & the UF Genetics Institute P.M. Pardalos is a permanent member of DIMACS. Next year, we are co-organizing an International Computational Challenge on vehicle routing problems (funded by NSF). The Center promotes collaboration with researchers at other universities through visitors and student exchange. The Center has an international reputation as reflected by invitations to deliver invited lectures, participate in international award committees (Kyoto Prize Committee, MacArthur award committee), and co-organize international conferences.

  • Travelling in a COVID World - T2RL’S Outlook
    Travelling in a COVID World - T2RL’s Outlook April 2021 2 INTRODUCTION This is the fourth edition of T2RL’s analysis of the market recovery for the airline industry during and after the COVID-19 pandemic. T2RL will update this document on a quarterly basis as new information and developments become apparent. T2RL’s View The world is a very different place today than it was this time last year, and even more dramatically different from 2019. It is also now apparent that some of the changes seen in the past year are here to stay for quite some time. The rollout of viable vaccines against COVID-19 has progressed in some markets since the start of the year, with most developed countries set to follow a steady path to vaccinating the majority of their populations by the start of 2022. For other markets, the timeline is a lot longer with countries like Cambodia, Fiji and Laos not expected to vaccinate at least 60% of their populations before 2025.1 This is unfortunately where the divide in the travel market will be. International travel and tourism are critical for many countries as a principal contributor to overall GDP. To balance the economic threat with the threat to the health of the local population without the need for lengthy quarantine periods, smart/digital vaccination certificates will be essential. As defined by the World Health Organisation (WHO), ‘the concept of digital vaccination certificates or “smart vaccination certificates” (SVCs) is proposed to provide a mechanism whereby an individual can present documentation that claims they have received a vaccine and this claim can be cryptographically verified by an interested party’’.2 1 The Economist Intelligence Unit, AAPA 2https://cdn.who.int/media/docs/default-source/documents/interim-guidance svc_20210319_final.pdf?sfvrsn=b95db77d_11&download=true Travelling in a COVID World: April 2021 © 2021 T2RL | Contains confidential information proprietary to T2RL | www.t2rl.com All rights reserved | Reproduction or redistribution in any form without the prior permission of T2RL is prohibited.
