An article co-authored by Professors Okan Arslan, Ola Jabali and Gilbert Laporte received an honourable mention in the awarding of the Best Paper of the Year Award by the international association INFORMS Transportation Science and Logistics (TSL).
Our faculty article ranked close second among the 26 submissions received this year at the INFORMS annual meeting for the Transportation Science and Logistics category.
This study, titled Exact Solution of the Evasive Flow Capturing Problem presents an innovative solution to a complex problem of intercepting illegal vehicles in a transportation network. It was first published in November 2018 in the journal Operations Research, which is part of the Financial Times list (FT50) of the 50 scientific journals with the most impact in the business sector.
INFORMS is the world’s largest association of operations research and analytics professionals and students. It has 12,500 members in 90 countries.
Okan Arslan is an Assistant Professor of operations research in the Department of Decision Sciences at HEC Montréal. He received his PhD in industrial engineering at Bilkent University. His field of expertise is design and management of networks. His research centres on investigating the impacts of disruptive technologies in transportation and logistics for businesses, households and governments.
Ola Jabali is an Assistant Professor in the operations research and discrete optimization group of DEIB (Dipartimento di Elettronica, Informazione e Bioingegneria) at Politecnico di Milano. She is also an Affiliated Professor in the Department of Logistics and Operations Management at HEC Montréal. She is a collaborating member of the Interuniversity Research Centre on Enterprise Networks, Logistics and Transportation (CIRRELT). In 2016 she won the prestigious Rita Levi Montalcini fellowship by the Italian Ministry of Education, University and Research. In 2015 she received the “Nouveau chercheur” prize at HEC Montréal. Her research focuses on optimizing goods transportation, in particular problems related to pollution, uncertainty, fleet composition, and customer service.
Gilbert Laporte is a Full Professor of operations research at HEC Montréal and Canada Research Chair in Distribution Management. He is the former editor-in-chief of Transportation Science, Computers & Operations Research and INFOR. He is a member of the Royal Society of Canada, from which he received the Innis-Gérin Medal in 2007. In 2009 he received the Robert M. Herman Lifetime Achievement Award in Transportation Science from the Transportation Science and Logistics Society of INFORMS, and in 2014 he was awarded the INFORMS Lifetime Achievement in Location Analysis.
In a transportation network, the regulatory authority locates law enforcement facilities to intercept unlawful vehicles, whereas these vehicles may deviate from their route up to a certain tolerance factor to avoid being intercepted. Taking this uncooperative behaviour into account, the objective of the “evasive flow capturing problem” is to determine the location of the law enforcement facilities. The problem has applications in transportation, revenue management, and security management. In “Exact Solution of the Evasive Flow Capturing Problem,” Arslan, Jabali, and Laporte develop a bilevel model and reformulate it using polyhedral theory to accelerate the solution process and to expand the size of the solvable instances of this highly complex problem.
