A branch-and-cut algorithm for the multidepot rural postman problem
(2018-03)
Article
Accés obertThis paper considers the Multidepot Rural Postman Problem, an extension of the classical Rural Postman Problem in which there are several depots instead of only one. The aim is to construct a minimum cost set of routes ... -
A consensus model for Delphi processes with linguistic terms and its application to chronic pain in neonates definition
(2015-10)
Article
Accés obertThis paper proposes a new model of consensus based on linguistic terms to be implemented in Delphi processes. The model of consensus involves qualitative reasoning techniques and is based on the concept of entropy. The ... -
A cutting-plane approach for large-scale capacitated multi-period facility location using a specialized interior-point method
(2016-09-19)
Article
Accés obertWe propose a cutting-plane approach (namely, Benders decomposition) for a class of capacitated multi-period facility location problems. The novelty of this approach lies on the use of a specialized interior-point method ... -

A data-driven learning method for constitutive modeling: application to vascular hyperelastic soft tissues
(Multidisciplinary Digital Publishing Institute (MDPI), 2020-05-01)
Article
Accés obertWe address the problem of machine learning of constitutive laws when large experimental deviations are present. This is particularly important in soft living tissue modeling, for instance, where large patient-dependent ... -
A finite point method for three-dimensional compressible flow
(2007-09)
Report de recerca
Accés obert -
A heuristic method for a congested capacitated transit assignment model with strategies
(2017-12)
Article
Accés obertThis paper addresses the problem of solving the congested transit assignment problem with strict capacities. The model under consideration is the extension made by Cominetti and Correa (2001), for which the only solution ... -
A Kalman filter approach for exploiting bluetooth traffic data when estimating time-dependent OD matrices
(2013-05-17)
Article
Accés obertTime-dependent origin–destination (OD) matrices are essential input for dynamic traffic models such as microscopic and mesoscopic traffic simulators. Dynamic traffic models also support real-time traffic management decisions, ... -
A Kalman filter approach for the estimation of time dependent OD matrices exploiting bluetooth traffic data collection
(2012)
Text en actes de congrés
Accés obertTime-Dependent Origin-Destination (OD) matrices are a key input to Dynamic Traffic Models, microscopic and mesoscopic traffic simulators are relevant examples of such models, traditionally used to assist in the design and ... -
A Kalman-filter approach for dynamic OD estimation in corridors based on bluetooth and wifi data collection
(2010-07)
Text en actes de congrés
Accés obertFrom the point of view of the information supplied by an ATIS to the motorists entering a freeway of one of the most relevant is the Forecasted Travel Time, that is the expected travel time that they will experience when ... -
A linear optimization based method for data privacy in statistical tabular data
(2017-06-15)
Article
Accés obertNational Statistical Agencies routinely disseminate large amount of data. Prior to dissemination these data have to be protected to avoid releasing confidential information. Controlled tabular adjustment (CTA) is one of ... -
A mathematical programming approach for different scenarios of bilateral bartering
(Institut d'Estadística de Catalunya, 2015-06)
Article
Accés obertThe analysis of markets with indivisible goods and fixed exogenous prices has played an important role in economic models, especially in relation to wage rigidity and unemployment. This paper provides a novel mathematical ... -
A measure of perceived performance to assess resource allocation
(Springer, 2016-08-01)
Article
Accés obertPerformance measurement is a key issue when a company is designing new strategies to improve resource allocation. This paper offers a new methodology inspired by classic importance-performance analysis (IPA) that provides ... -
A method of multiobjective decision making using a vector value function
(Institut d'Estadística de Catalunya, 1994)
Article
Accés obertA decision situation with partial information on preferences by means of a vector value function is assumed. The concept of minimum value dispersion solution as a reference point joined with a pseudodistance function from ... -
A methodology for constructing fuzzy rule based classification systems
(Universitat Politècnica de Catalunya. Secció de Matemàtiques i Informàtica, 2000)
Article
Accés obertIn this paper, a methodology to obtain a set of fuzzy rules for classification systems is presented. The system is represented in a layered fuzzy network, in which the links from input to hidden nodes represents the ... -

A model for the simultaneous selection of bus lines and frequency setting problems in the expansion of public transit systems
(Elsevier, 2020-03-02)
Article
Accés obertWhen expanding an existing public transport system a common practice consists of defining a set of candidate new lines andfrom them, choose those that will revert into a greater increase of the system’s performance while ... -
