Bilevel optimization based on iterative approximation of multiple mappings
(Journal of Heuristics, 2020)
A large number of application problems involve two levels of optimization, where one optimization task is nested inside the other. These problems are known as bilevel optimization problems and have been studied by both ...
Alternate solution approaches for competitive hub location problems
(European Journal of Operational Research, 2020-08-08)
In this paper, we study the hub location problem of an entrant airline that tries to maximize its share in a market with already existing competing players. The problem is modeled as a non-linear integer program, which is ...
Competitive hub location problems: model and solution approaches
(Elsevier, 2021-03-07)
In this paper, we study the hub location problem of an airline that wants to set up its hub and spoke network, in order to maximize its market share in a competitive market. The market share is maximized under the assumption ...
