Center location problems on tree graphs with subtree-shaped customers
(Elsevier, 2008-08-06)
We consider the p-center problem on tree graphs where the customers are modeled as continua subtrees. We address unweighted and weighted models as well as distances with and without addends. We prove that a relatively ...

A generalized model of equality measures in network location problems
(Elsevier, 2008-03)
In this paper, the concept of the ordered weighted averaging operator is applied to define a model which unifies and generalizes several inequality measures. For a location x, the value of the new objective function is the ...
