  Some Applications of Benders Decomposition to Facility Location and Network Design Problems

  Department of Industrial Engineering and Management Sciences (IEMS)

  11:00 AM CEE Conference Rm A230, Technological Institute

  EVENT DETAILS

  Talk abstract: Benders decomposition is a mathematical decomposition technique designed to solve large-scale linear and mixed-integer programs. Since its introduction in 1962, the approach has been successfully applied to a wide variety of problems arising in supply chain management, transportation, telecommunications, and energy management. Despite its success, however, it has long been overshadowed by dual decomposition methods such as Lagrangian relaxation and Dantzig-Wolfe decomposition. Over the last two decades, one has witnessed a renewed interest in Benders decomposition with the introduction of several novel ideas to improve performance. The purpose of this talk is to give an overview of the main acceleration techniques by focusing on two families of problems where Benders decomposition has proven especially effective: facility location problems and network design problems. After briefly explaining the general methodology and practical enhancements, we will present examples of successful applications to set covering problems and fixed-charge network design problems. In each case, we will focus on strategies for generating strong cuts efficiently, including the application of unified cut generation frameworks and the use of normalization constraints in the dual subproblem.

  Bio: Jean-François Cordeau obtained his Ph.D. in Applied Mathematics at École Polytechnique de Montréal in 1999. He is a professor of Operations Management at HEC Montréal, where he also holds the Chair in Logistics and Transportation. He has authored or co-authored more than 175 scientific articles in combinatorial optimization and mathematical programming, focusing primarily on vehicle routing and logistics network design. He has also supervised more than 75 M.Sc. and Ph.D. students. Dr. Cordeau is an Area Editor of Transportation Science and a member of the Editorial Board of Computers & Operations Research. He has worked as a consultant for several Canadian and European organizations in the private and public sectors. He is currently one of the scientific directors of IVADO Labs. He received the Canadian Operational Research Society (CORS) Award of Merit in 2016 and the Pierre-Laurin Award for Research Excellence at HEC Montréal in 2018. In 2023, he and ten of his colleagues won the CORS Practice Prize for their work on maritime vessel routing.

  Fall Seminar 2024: Adoption of AI in the Travel Industry Featuring Sergey Shebalov

  Master of Science in Machine Learning and Data Science (MLDS)

  3:30 PM Krebs Classroom, Henry Crown Sports Pavilion

  EVENT DETAILS

  Join us for an insightful seminar featuring Sergey Shebalov about the resurgence of Artificial Intelligence. We will delve into real-world use cases, the challenges and opportunities in AI adoption, and the impact of AI on the travel industry.

  Lecture Summary: Artificial Intelligence is experiencing resurrection over the last several years. The number of use cases already implemented in practice and the amount of investment allocated to development and adoption of this technology indicates that this time it's here to stay. While several challenges still remain and some new ones are anticipated the path towards Al becoming as common as computer, smartphone or internet is clear. We will discuss this journey on the example of the travel industry. We'll consider several main applications of Al that already provided significant benefits, a typical process these applications go through from an idea to a full-scale adoption, and the skills required to support that process from the new generation of leaders, scientists, engineers and practitioners.

  Sergey Shebalov is a VP of Data Science and Head of Research at Sabre. He leads the Sabre Labs team responsible for development and implementation of complex Al decision support systems. Sergey holds PhD in mathematics from University of Illinois and has two decades of experience in the travel industry IT. His area of expertise is intelligent retailing,

  resource optimization and adoption of Al in practice.

  Location: Krebs Classroom, McCormick Education Center, 2311 Campus Dr
