Capacitated multi-period maximal covering location problem with server uncertainty
(European Journal of Operational Research, 2020-08-07)
We study the problem of assigning doctors to existing, non-operational Primary Health Centers (PHCs). We do this in the presence of clear guidelines on the maximum population that can be served by any PHC, and uncertainties ...
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 ...
An integrated bottom-up optimization to investigate the role of BECCS in transitioning towards a net-zero energy system: a case study from Gujarat, India
(Elsevier, 2022-06-15)
Bringing down energy system emissions to zero is a key step to restrict the global temperature rise to “well below 2 °C”. Recent studies have extensively discussed the integration of bioenergy with carbon capture and storage ...
Capacitated multiple allocation hub location problems under the risk of interdiction: model formulations and solution approaches
(Springer Nature, 2023-08-31)
Hub-and-spoke networks play a critical role in reducing cost and enhancing service levels in various infrastructural sectors since hubs act as the consolidation and transshipment points of the flows. The failure of hubs ...
Multiple allocation hub location with service level constraints for two shipment classes
(Elsevier, 2023-02-07)
In this paper, we study a hub network design problem arising in the context of a third-party logistics (3PL) service provider, which acts as an intermediary between shippers and carriers. A 3PL service provider usually ...
The capacitated r-hub interdiction problem with congestion: Models and solution approaches
(Elsevier, 2024-03-27)
We study the r-hub interdiction problem under the case of possible congestion. Hub interdiction problems are modeled as attacker-defender problems to identify a set of r critical hubs from a set of p hubs, which when ...
