Solving nonconvex planar location problems by nite dominating sets
(Springer, 2000-10)
It is well-known that some of the classical location problems with polyhedral gauges can be solved in polynomial time by nding a fi nite dominating set, i.e. a finite set of candidates guaranteed to contain at least one ...

Locating a semi-obnoxious covering facility with repelling polygonal regions
(ELSEVIER SCIENCE BV, 2013-11-01)
A facility is to be located in the Euclidean plane to serve certain sites by covering them closely. Simultaneously, a set of polygonal areas must be protected from the negative effects from that facility. The problem is ...

Revisiting several problems and algorithms in continuous location with lp norms
(Springer, 2014-07)
This paper addresses the general continuous single facility location problems in finite dimension spaces under possibly different ℓp norms in the demand points. We analyze the difficulty of this family of problems and ...

On minimax-regret Huff location models
(Elsevier, 2011-01)
We address the following single-facility location problem: a firm is entering into a market by locating one facility in a region of the plane. The demand captured from each user by the facility will be proportional to the ...

Weber problems with alternative transportation systems
(ELSEVIER SCIENCE BV, 1997-02-16)
In this paper we address a planar p-facility location problem where, together with a metric induced by a gauge, there exists a series of rapid transit lines, which can be used as alternative transportation system to reduce ...

Continuous location problems and Big Triangle Small Triangle: constructing better bounds
(Springer, 2009-11)
The Big Triangle Small Triangle method has shown to be a powerful global optimization procedure to address continuous location problems. In the paper published in J. Global Optim. (37:305–319, 2007), Drezner proposes a ...

Continuous location under the effect of ‘refraction’
(Springer, 2016-03-08)
In this paper we address the problem of locating a new facility on a d-dimensional space when the distance measure (- or polyhedral-norms) is different at each one of the sides of a given hyperplane. We relate this problem ...
