November 6, 2019
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.

The subject of the Article in Brief
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.
