Optimal Positioning of a Mobile Service Unit on a Line
(Springer, 2002-03-01)
In this paper we address the problem of locating a mobile response unit when demand is distributed according to a random variable on a line. Properties are proven which reduce the problem to locating a non-mobile facility, ...

Network flow based approaches for the pipelines routing problem in naval design
(Elsevier, 2022)
In this paper we propose a general methodology for the optimal automatic routing of spatial pipelines motivated by a recent collaboration with Ghenova, a leading Naval Engineering company. We provide a minimum cost ...
Article
A combinatorial optimization approach to scenario filtering in portfolio selection
(Elsevier, 2022-02-05)
Recent studies stressed the fact that covariance matrices computed from empirical financial time series appear to contain a high amount of noise. This makes the classical Markowitz Mean–Variance Optimization model unable ...

Production-inventory games: A new class of totally balanced combinatorial optimization games
(Elsevier, 2009)
In this paper we introduce a new class of cooperative games that arise from production-inventory problems. Several agents have to cover their demand over a finite time horizon and shortages are allowed. Each agent has its ...

On location-allocation problems for dimensional facilities
(Springer, 2019)
This paper deals with a bilevel approach of the location-allocation problem with dimensional facilities. We present a general model that allows us to consider very general shapes of domains for the dimensional facilities ...

Multi-criteria minimum cost spanning tree games
(Elsevier, 2004)
The minimum cost spanning tree game (mcst-game) is a well-known model within operations research games that has been widely studied in the literature. In this paper we introduce the multi-criteria version of the mcst-game ...

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 management tool for indicator-supported systems: A public health service application
(ELSEVIER SCIENCE BV, 1992-01-01)
We develop a decision-making methodology for hierarchical structures. It provides different decision makers with decision-oriented information based on obtained satisfaction levels. This is specially convenient for public ...
