Continuous approximation formulas for location problems
Networks, 2022 AbstractThe majority of research in the continuous approximation paradigm has emphasized routing problems, such as the travelling salesman problem and the vehicle routing problem. This article instead focuses on continuous approximation formulas for problems involving location, specifically the ‐medians, ‐dispersion, and generalized minimum spanning ...

A new local search for continuous location problems [PDF]
European Journal of Operational Research, 2014 This paper presents a new local search approach for solving continuous location problems. The main idea is to exploit the relation between the continuous model and its discrete counterpart. A local search is first conducted in the continuous space until a local optimum is reached. It then switches to a discrete space that represents a discretisation of

Locally differentially private continuous location sharing with randomized response
International Journal of Distributed Sensor Networks, 2019 With the growing popularity of fifth-generation-enabled Internet of Things devices with localization capabilities, as well as on-building fifth-generation mobile network, location privacy has been giving rise to more frequent and extensive privacy ...

Improved starting solutions for the planar p-median problem [PDF]
Yugoslav Journal of Operations Research, 2021 In this paper we present two new approaches for finding good starting solutions to the planar p-median problem. Both methods rely on a discrete approximation of the continuous model that restricts the facility locations to the given set of demand points.

Continuous Facility Location on Graphs [PDF]
Mathematical Programming, 2020 AbstractWe study a continuous facility location problem on undirected graphs where all edges have unit length and where the facilities may be positioned on the vertices as well as on interior points of the edges. The goal is to cover the entire graph with a minimum number of facilities with covering range $$\delta >0$$

Single Facility Goal Location Problems with Symmetric and Asymmetric Penalty Functions [PDF]
Control and Optimization in Applied Mathematics, 2019 Location theory is an interstice field of optimization and operations research. In the classic location models, the goal is finding the location of one or more facilities such that some criteria such as transportation cost, the sum of distances passed by
