Dynamically second-preferred p-center problem
(Elsevier, 2023)
This paper deals with the Dynamically Second-preferred p-center Problem (DSpP). In this problem, cus- tomers’ preferences and subsets of sites that each customer is willing to accept as service centers are taken into ...

Segmentation of scanning-transmission electron microscopy images using the ordered median problem
(Elsevier, 2022-01-15)
This paper presents new models for segmentation of 2D and 3D Scanning-Transmission Electron Micro- scope images based on the ordered median function. The main advantage of using this function is its good adaptability to ...

On the exponential cardinality of FDS for the ordered p-median problem
(Elsevier, 2005)
We study finite dominating sets (FDS) for the ordered median problem. This kind of problems allows to deal simultaneously with a large number of models. We show that there is no valid polynomial size FDS for the general ...

A unified approach to network location problems
(John Wiley and Sons, 1999)
In this paper we introduce a new type of single facility location problems on networks which includes as special cases most of the classical criteria in the literature. Structural results as well as a finite dominating set ...

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 ...

A fresh view on the Discrete Ordered Median Problem based on partial monotonicity
(Elsevier, 2020-04-14)
This paper presents new results for the Discrete Ordered Median Problem (DOMP). It exploits properties of k-sum optimization to derive specific formulations for the monotone DOMP (MDOMP), that arises when the λ weights are ...
