Facility location with hierarchical facility costs
ACM Transactions on Algorithms, 2006We introduce a facility location problem with submodular facility cost functions, and give an O (log n ) approximation algorithm for it. Then we focus on a special case of submodular costs, called hierarchical facility costs, and give a (4.237 + ϵ)-approximation algorithm using local search ...

Maximum coverage capacitated facility location problem with range constrained drones
Transportation Research Part C: Emerging Technologies, 2019Given a set of demand and potential facility locations and a set of fully available charged drones, an agency seeks to locate a pre-specified number of capacitated facilities and assign drones to the located facilities to serve the demands.

Online Facility Location with Mobile Facilities
Proceedings of the 30th on Symposium on Parallelism in Algorithms and Architectures, 2018We examine the Online Facility Location Problem in an augmented version, where the online algorithm is allowed to adapt the position of the facilities for costs proportional to the distance by which the position is changed. In this setting, it is possible to construct online algorithms which deal with the lower bound instances of Online Facility ...

Facility location games with optional preference
Theoretical Computer Science, 2020In this paper, we study the optional preference model of the facility location game problem with two heterogeneous facilities on a line. The preference of each agent is one of the two facilities or both facilities, and the cost of each agent is a ...

In the Universal Facility Location problem we are given a set of demand points and a set of facilities. The goal is to assign the demands to facilities in such a way that the sum of service and facility costs is minimized. The service cost is proportional to the distance each unit of demand has to travel to its assigned facility, whereas the facility ...

Approximate mechanism design for distributed facility location
Algorithmic Game Theory, 2020We consider the distributed facility location problem, in which there is a set of agents positioned on the real line, who are also partitioned into multiple symmetric districts.

Including deprivation costs in facility location models for humanitarian relief logistics
Socio-Economic Planning Sciences, 2019Humanitarian assistance is meant to save lives and alleviate human suffering during and in the aftermath of man-made and natural disasters. To prevent and strengthen preparedness for the occurrence of such situations, having available relief supplies in ...
