The continuous grey pattern problem
A new location problem is formulated and solved. It is the continuous version of the...
Mixed planar and network single-facility location problems
We consider the problem of optimally locating a single facility anywhere in a network...
Sequential location of two facilities: comparing random to optimal location of the first facility
We investigate sequential location of two facilities. One strategy is to locate the...
Maximizing the minimum cover probability by emergency facilities
In this paper we propose a stochastic model for the location of emergency facilities....
New local searches for solving the multi-source Weber problem
This paper presents three new heuristic approaches for the solution of the...
The wisdom of voters: evaluating the Weber objective in the plane at the Condorcet solution
We investigate the quality of Condorcet solutions when compared to a central decision...
New heuristic algorithms for solving the planar p-median problem
In this paper we propose effective heuristics for the solution of the planar p...
The Quintile Share Ratio in location analysis
The inequality measure ‘Quintile Share Ratio’ (QSR or sometimes S80/S20)...
Location of a distribution center for a perishable product
A model that combines an inventory and location decision is presented, analyzed and...
Voronoi diagrams with overlapping regions
Voronoi diagrams are a tessellation of the plane based on a given set of points...
Enhancing the performance of hybrid genetic algorithms by differential improvement
A differential improvement modification to Hybrid Genetic Algorithms is proposed. The...
A new heuristic for solving the p‐median problem in the plane
This paper presents a new local search for solving the continuous p‐median...
The Weber Location Problem: The Threshold Objective
A new objective for the Weber location problem is proposed. The weights of the Weber...
A note on equity across groups in facility location
An equity model between groups of demand points is proposed. The set of demand points...
Normalizing variables with too‐frequent values using a Kolmogorov–Smirnov test: A practical approach
Many quantitative applications in business operations, environmental engineering, and...
On the unboundedness of facility layout problems
Facility layout problems involve the location of facilities in a planar arrangement...
Cooperative cover location problems: The planar case
A cooperative-covering family of location problems is proposed in this paper. Each...
A stochastic gradual cover location problem
Covering models assume that a point is covered if it is within a certain distance from...
A new formulation for the conditional p-median and p-center problems
In this paper we discuss the conditional p -median and p -center problems on a...
Location and allocation of service units on a congested network
We consider the problem of locating facilities and allocating servers on a congested...
The route expropriation problem
This paper considers the problem of selecting obnoxious routes (e.g., routes used to...
On the convergence of the generalized Weiszfeld algorithm
In this paper we consider Weber-like location problems. The objective function is a...
Single facility location and relocation problem with time dependent weights and discrete planning horizon
In this paper a single facility location problem with multiple relocation...
