A multi-objective and multi-criteria approach for district metered area design: water operation and quality analysis
2019
Water distribution network (WDN) operation may be improved by district metered area (DMA) design [1]. A first step to create DMAs uses graph theory and non-supervised learning, where physical features of the WDN, such as node coordinates, elevation and demand, are used for clustering purposes [2]. A second step is related to the necessary isolation of the clustered elements. For isolation purposes, it is important to determine the DMA entrances and, consequently, the needed cut-off valves. Closure of pipes and definition of DMA entrances can be set as an optimization problem with the costs associated to the valves, which are linked to pipe diameters, as a primary objective. However, placeme…
MULTICRITERIA ANALYSIS – INSTRUMENT FOR AN ACCURATE ANALYSIS OF THE IMPACT OF THE SERVICE SECTOR ON THE ECONOMY
2013
The current paper represents an attempt to introduce multicriteria analysis as an efficient instrument to prove that the development of services in Romania has a major impact on all aspects of our economy and represents the right path to pursue in terms of economic growth, on a medium and long term basis.The paper presents a general approach to multicriteria analysis as a means to successfully reveal the impact of the service sector on the economy of Romania. Several advantages as well as limits are presented, along with a brief presentation of the concept of composite synergy of services, corollary of the multicriteria analysis.
Multicriteria Decision Aiding for Planning Renewable Power Production at Moroccan Airports
2022
This study is about multicriteria decision aiding (MCDA) for the green airports program of the Moroccan Airport Authority ONDA. The goal of the program is to develop significant amounts of renewable power at airports. In particular, ONDA wants to select airports at which large solar and wind power parks should be built. Multiple criteria, including economy, technical feasibility, and environmental concerns, must be considered simultaneously. In this study, we apply Stochastic Multicriteria Acceptability Analysis (SMAA) for ranking the candidates to be developed into green airports. The analysis is conducted in phases with different sets of criteria. This study is the first application of MC…
Valutazione multicriteriale del saggio di capitalizzazione per la revisione del catasto degli immobili urbani - Capitalization rate multidimensional …
2013
The new revision of the land register is intended to give each real estate unit an assessed value which approximates the market value. The provided approach has statistical nature. However, in the absence of a well-established market, the coming reform requires the use of the indirect estimation procedure.This paper proposes a method for estimating the capitalization rate that could usefully be applied in mass appraisal. The proposed model for the evaluation of the capitalization rate is intended as an alternative to traditional inferential processes that apply in real estate market. It can be used even in market segments that are not enough active and does not require the use of technical …
Structural Design of Frames Able to Prevent Element Buckling
2012
Two formulations of a special multicriterion optimal design problem devoted to elastic perfectly plastic steel frame structures subjected to different combinations of static and dynamic loads are presented. In particular, two minimum volume design problem formulations are proposed: in the first one the structure is designed so as to be able to elastically behave for the assigned fixed loads, to elastically shakedown for serviceability seismic load conditions and to prevent the instantaneous collapse for suitably chosen combinations of fixed and ultimate seismic loadings; in the second one the structure must also satisfy further appropriate constraints related to element buckling. The action…
Psychological variables and temporomandibular disorders: distress, coping, and personality.
2004
Abstract Objective This study analyzes the psychological variables of distress, personality, and coping that are related to the diagnosis based on the Research Diagnostic Criteria for temporomandibular disorder. Study design An age and sex-matched controlled study conducted with a convenience sample (n = 89) in a tertiary care facility. Results The MANCOVA between the muscular (n = 47), articular (n = 42), and control groups (n = 100) showed that the muscular group differed from the control group, obtaining higher levels of distress, anxiety, and depression, and minor use of positive reinterpretation and humor as coping strategies; the articular group also showed higher distress, less posit…
The challenge of using the rheumatoid arthritis diagnostic criteria in clinical practice.
2015
The new 2010 ACR/EULAR (American College of Rheumatology/European League Against Rheumatism) criteria of Rheumatoid Arthritis recently published, have been released to classify and identify patients with early RA who could benefit from early therapy. They recommend anti-citrullinated protein antibody (ACPA) testing as an alternative criterion to Rheumatoid Factor (RF) and ACPA that were introduced together with the other classic criteria in a scoring system. We previously criticized these new criteria because of unavailable specificity and sensibility in the first paper, and the use of ACPA as dichotomous criterion (presence/absent) and alternatives to rheumatoid factor. Our previous work p…
ESE. Estudios sobre educación
2011
Título, resumen y palabras clave también en inglés Resumen basado en el de la publicación Incluye como anexo el cuestionario Se presenta la validación de un cuestionario de evaluación de los métodos de enseñanza y evaluación que utilizan los profesores universitarios en su materia y qué habilidades docentes manejan. Se pretende valorar en qué medida los métodos de enseñanza y evaluación usados inciden en el modo de abordar el aprendizaje de los estudiantes. Se parte de la teoría vigente, que establece dos modelos, uno centrado en la enseñanza y otro en el aprendizaje, para elaborar dos de las tres escalas del instrumento de medida. La tercera se elaboró a partir de la teoría sobre las habil…
A comparative analysis of the sustainability of rice cultivation technologies using the analytic network process
2010
Sustainability of local farming systems and technologies is a very important issue that faces notorious measurement difficulties. Multi-criteria methods may help researchers to solve empirical problems in the construction of composite sustainability indicators and in ranking agricultural technologies according to their sustainability. This paper shows how a multi-criteria decision-making technique, the Analytic Network Process (ANP), can be fruitfully employed to this end. Contrary to simpler and hierarchical goal-criteria-alternative approaches, in ANP all the elements in the network can be related in any possible way, which means that a network can incorporate feedback and interdependent …
La selección de las noticias en el entorno de un centro de documentación de información de actualidad
2002
In information retrieval systems operation, lack of adequate selection criteria originates information overload and has negative consequences in relevance judgments. In the context of a news reference service, three leveis in the selection process are proposed. The first one relates to the type of sources covered by the system, the second set of criteria determines which publications are included in the process of document analysis. The last one applies to the selection of individual documents based on their informative content. La falta de criterios idóneos de selección puede provocar un grave problema de saturación informativa, lo que repercute negativamente en la búsqueda posterior de in…
