A discretization result for some optimization problems in framework spaces with polyhedral obstacles and the Manhattan metric [Article]
In this work we consider the shortest path problem and the single facility Weber location problem in any real space of finite dimension where there exist different types of polyhedral obstacles or forbidden regions. These ...
Railway traffic disturbance management by means of control strategies applied to operations in the transit system [Article]
(WIT Press, 2018)
Railway systems in metropolitan areas support a high density of daily traffic that is exposed to different types of disturbances in the service. An interesting topic in the literature is to obtain action protocols in the ...
A market regulation bilevel problem: a case study of the Mexican petrochemical industry [Article]
In this paper, a bilevel programming model is proposed to study a problem of market regulation through government intervention. One of the main characteristics of the problem herein analyzed is that the government ...
Mathematical programming formulations for the efficient solution of the k-sum approval voting problem [Article]
In this paper we address the problem of electing a committee among a set of m candidates and on the basis of the preferences of a set of n voters. We consider the approval voting method in which each voter can approve as ...
Inferring efficient weights from pairwise comparison matrices [Article]
Several multi-criteria-decision-making methodologies assume the existence of weights associated with the different criteria, reflecting their relative importance.One of the most popular ways to infer such weights is the ...
