Exact Methods for Solving k-Delete Recoverable Robust 0-1 Problems Under Budgeted Uncertainty
Yasmine Beck, Christina Büsing, Ivana Ljubić
We study the k-delete recoverable robust 0-1 problem in which a decision-maker solves a combinatorial optimization problem subject to objective uncertainty. The model follows a two…
Modeling Network Congestion under Demand Uncertainty Using Wardrop Principles
Yasmine Beck, Francesca Giancola, Ivana Ljubić +1
Motivated by the need for reliable traffic management under fluctuating travel demand, we study the problem of determining the worst-case congestion in a multi-commodity traffic ne…
An efficient branch-and-cut algorithm for the multiple probabilistic covering location problem
Yan-Ru Wang, Wei-Kun Chen, Ivana Ljubić
In this paper, we consider the multiple probabilistic covering location problem (MPCLP), which attempts to open a fixed number of facilities to maximize the total covered customer…
Bilevel optimization with sustainability perspective: A survey on applications
Giulia Caselli, Manuel Iori, Ivana Ljubić
Bilevel optimization, a well-established field for modeling hierarchical decision-making problems, has recently intersected with sustainability studies and practices, resulting in…
Benders decomposition for congested partial set covering location with uncertain demand
Alice Calamita, Ivana Ljubić, Laura Palagi
In this paper, we introduce a mixed integer quadratic formulation for the congested variant of the partial set covering location problem, which involves determining a subset of fac…
Operational Research: Methods and Applications
Fotios Petropoulos, Gilbert Laporte, Emel Aktas +79
Throughout its history, Operational Research has evolved to include a variety of methods, models and algorithms that have been applied to a diverse and wide range of contexts. This…
A Brief Introduction to Robust Bilevel Optimization
Yasmine Beck, Ivana Ljubić, Martin Schmidt
Bilevel optimization is a powerful tool for modeling hierarchical decision making processes. However, the resulting problems are challenging to solve - both in theory and practice.…
