Continuous location of dimensional structures [PDF]
European Journal of Operational Research, 2004 In classical location problems, we have to find one or several points for placing new facilities such that they optimize one or several possibly constrained objective functions. Usually the functions depend on the interactions among demand points and new facilities.

Mathematical Models and Nonlinear Optimization in Continuous Maximum Coverage Location Problem
Computation, 2022 This paper considers the maximum coverage location problem (MCLP) in a continuous formulation. It is assumed that the coverage domain and the family of geometric objects of arbitrary shape are specified.

Conditional facility location problems with continuous demand and a polygonal barrier [PDF]
, 2022 We consider facility location problems where n facilities are present in a convex polygon in the rectilinear plane, over which continuous and uniform demand is distributed and within which a convex polygonal barrier is located (removing all demand and ...

Continuous location privacy protection mechanism based on differential privacy
Tongxin xuebao, 2021 Aiming at the problem of users’ location privacy leakage caused by continuously using LBS, a road privacy level (RPL) algorithm was proposed based on road topological network, which divided the privacy level of the road sections around the sensitive ...

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 Privacy-Preserving Continuous Location Monitoring System for Location-Based Services
International Journal of Distributed Sensor Networks, 2015 To protect users’ private locations in location-based services, various location anonymization techniques have been proposed. The most commonly used technique is spatial cloaking, which organizes users’ exact locations into cloaked regions (CRs).
