The fuzzy p-median problem

International Journal of Technology, Policy and Management, 2004
In many location models, the strong crisp assumptions, like known demands and distances, are not realistic in most cases. The fuzzy p-median problem relaxes this hypothesis giving to the decision maker a necessary degree of freedom to solve real-world problems.

A new heuristic approach for the P-median problem

Journal of the Operational Research Society, 1997
Summary: The Euclidean \(p\)-median problem is concerned with the decision of the locations for public service centres. Existing methods for the planar Euclidean \(p\)-median problems are capable of efficiently solving problems of relatively small scale. This paper proposes two new heuristic algorithms aiming at problems of large scale.

A swarm intelligence approach for the p-median problem

International Journal of Metaheuristics, 2016
p-median problem is a well-known facility location problem which aims at locating p number of facilities over n demand points in such a way that the sum of distances from all the demand points to their respective closest facilities is minimised. In this paper, we have proposed an artificial bee colony ABC algorithm-based approach for solving this NP ...

New Genetic Algorithm for the p-Median Problem

2014
The p-median problem is a well-known combinatorial optimization problem with several possible formulations and many practical applications in areas such as operational research and planning. It has been also used as a testbed for heuristic and metaheuristic optimization algorithms. This work proposes a new genetic algorithm for the p-median problem and
