Advanced Methods in Operations Research for Logistics and Transportation

In the context of decision-making processes, we use Operations Research methods to understand, predict and optimize the behavior of real-life systems through mathematical models. Operations Research techniques are designed to tackle problems with practical meaning, which are typically very complex. These models and methods have been applied in numerous contexts such as defining public and private policies, and planning processes for government and industry with an exceptionally broad spectrum.

General Objectives
  • To promote scientific collaboration in research lines that focus on advanced methods in Operations Research
  • To present state-of-the-art methodologies and problems within the context of Logistics and Transportation.
Specifics Objectives
  • To present concrete applications in Logistics and Transportation where advanced optimization and machine learning techniques are applied.
  • To stablish potential future lines of research.
  • To communicate recent research projects of the participants and the invited speakers.
  • To introduce state-of-the-art solution methods for various optimization and prediction problems in Logistics and Transportation.
Value proposal

In the context of decision-making processes, we use Operations Research methods to understand, predict and optimize the behavior of real-life systems through mathematical models. Operations Research techniques are designed to tackle problems with practical meaning, which are typically very complex. These models and methods have been applied in numerous contexts such as defining public and private policies, and planning processes for government and industry with an exceptionally broad spectrum.

Nowadays, in the era of information and data, the development of technological tools that support the decision-making process gains vital importance, which in turn, reaffirms the value of studying Operations Research methods. The area of Logistics and Transportation systems is a special case where the technological growth is evident in the last two decades. There, predicting patterns and optimizing decisions plays a major role in the overall operations. Moreover, this area has been a particular source of study for researchers and practitioners in Operations Research. The problems encountered usually represent a high-value decision but also, they possess an intrinsic mathematical structure that provoke a detailed scientific study.

Having in mind today’s global requirements in the development of algorithms and efficient solution methods to problems that appear in the contexts of Logistics and Transportation we have elaborated an initiative to promote the better understanding of cutting-edge technology and the scientific collaboration for the design and creation of new models and methods in Operations Research.

Method

There will be four short courses or modules in recent topics of Operations Research. Each module consists of 6 hours of lecture and will be taught by a different expert. There will be time for questions and comments from the participants. We will also offer a 6 hours hands-on workshop on specialized optimization software.

There will be parallel sessions for short talks and poster presentations from the research projects of the participants.

All the modules and workshop will be in English. The presentations from the participants must be either in English or in Spanish with the slides in English.

Addressed to

The school is targeted to all the members of the academic community and practitioners who are interested in advanced topics in Operations Research. We expect the focus of participants to be graduate students from the areas of mathematics, industrial engineering and computer science. It is important the interested applicant has some knowledge of Operations Research methods.

Academic Content

  • Models and Decomposition Methods for Large-Scale Network Optimization (Prof. Ivan Contreras)

    Abstract:
    Network optimization problems lie at the hearth of network design planning in transportation and telecommunications systems. This series of talks focus on a challenging class of problems referred to as general network design, which offers a unified view of integrated facility location, and network design. Their main difficulty stems from the inherent interrelation between two levels of the decision process. The first level considers design decisions such as the selection of nodes to locate facilities and the activation of links to connect nodes. The second level considers tactical decisions such as the assignment of nodes to facilities and the routing of flows through the network. We present an overview of some of the most prominent mathematical programming formulations that have been used in combination with decomposition methods to develop state-of-the-art exact solution algorithms capable of solving large-scale instances of three important classes of problems involving both linear and nonlinear cost functions: hub network design, multi-level facility location, and multi-commodity network design. We highlight the connections between Lagrangean relaxation, Dantzig-Wolfe decomposition, Benders decomposition, and related primal relaxations in the context of such problems. We also point out to several algorithmic refinements that have been used to accelerate the convergence of such decomposition methods. Practical implementation guidelines to improve their overall performance are discussed.

    Constraint Programming for Optimisation (Prof. Louis-Martin Rousseau)

    Abstract:
    In these series of sessions, we will present the key concepts of Constraint Programming (CP) and illustrate how it can be applied to classic and combinatorial problems, such as the Traveling Salesman Problem and Vehicle Routing Problem as well as some real-life challenges, which arise in supply chain logistics. We will illustrate the efficiency of CP in context of personnel scheduling model, and discuss some realistic cases study from the Canadian industry. Finally, we will give an intuitive introduction to Column Generation and illustrate how CP can be used a pricing strategy.
