    Tennis performance is influenced by various factors, among which physical performance factors play an important role. The aim of the study was an analysis of possibilities of the use of Saaty’s method for assessing the level of performance prerequisites and comparing the results obtained using equal weights and various weights. The research on Czech female players (U12; n = 211) was based on the results of the TENDIAG1 test battery (9 items) and the results were processed by FuzzME software and relevant statistical methods (correlation coefficient r, Student´s t-test, effect size index d). The results of Saaty's method show that the most important athletic performance criteria for tennis coaches are the leg reaction time and the running speed, while the least important are endurance and strength. The evaluation using various criteria weights offers a finer scale for assessing athletes’ performance prerequisites despite the proven high degree of association between the results obtained with equal and various weights and the insignificant difference of mean values. The results have shown possibilities for the use of a fuzzy approach in sports practice and motivate further research towards broadening the structure or the number of evaluation criteria.Tennis performance is influenced by various factors, among which physical performance factors play an important role.

    Agri-food building performance evaluation by an integration of different measurement techniques: Case study of a bakery in south Italy

    Abstract The performance of a building plays a key role in its sustainability, since a building cannot be sustainable if the needs of its users are not satisfied. In fact, the priority of a sustainable building is to meet the user requirements in an adequate manner, while limiting its environmental impact. The aim of this study is to supply a suitable Building Performance Evaluation method (BPE) to technicians, facility managers and designers, in order to improve the quality of management, design and construction by providing more sustainable agri-food buildings. In this study, in order to measure building performance with respect to user requirements, the simultaneous application of three different measurement techniques was proposed: a User survey by means of a questionnaire; an analysis of building documents and a walkthrough analysis by experts; and instrumental measurements and a direct survey of building characteristics. The proposed BPE method was based on a fuzzy weighted average at three levels. The fuzzy method proved to be particularly suitable for describing the vagueness of users when answering the questionnaire, for translating the document analysis, or considering the instrumental measurements for performance measures. The proposed method was applied to a typical agri-food building in southern Italy. This application demonstrated the correctness of the setting, its ease of application, and its ability to manage real cases. The method allowed for the evaluation of building performance by taking advantage of the positive characteristics of each measurement technique: the users' and occupants' perception, the knowledge and critical sense of expert technicians, and the accuracy and objectivity of instrumental measures. The results of the model were represented by mean fuzzy membership functions, which preserved the "vagueness" of the initial performance attributes. To obtain more synthetic values, a normalization procedure was applied to obtain a value performance judgment, expressed by a number in the range of 0 and 1 (where 0 is the worst and 1 is the best). The general performance of functional areas and the differences in performance in the same functional area were compared using this operation. The results of the case study demonstrated the reliability of the proposed method; in particular, it can determine the state of the building's functionality, drawing attention to weak points that should be monitored to prevent potential faults. The method proposed is a key element intended to help develop agri-food buildings that are effective and efficient and perform as expected and it contributes to improve the general quality of agri-food buildings

    A Survey of Fuzzy Systems Software: Taxonomy, Current Research Trends, and Prospects

    Fuzzy systems have been used widely thanks to their ability to successfully solve a wide range of problems in different application fields. However, their replication and application require a high level of knowledge and experience. Furthermore, few researchers publish the software and/or source code associated with their proposals, which is a major obstacle to scientific progress in other disciplines and in industry. In recent years, most fuzzy system software has been developed in order to facilitate the use of fuzzy systems. Some software is commercially distributed, but most software is available as free and open-source software, reducing such obstacles and providing many advantages: quicker detection of errors, innovative applications, faster adoption of fuzzy systems, etc. In this paper, we present an overview of freely available and open-source fuzzy systems software in order to provide a well-established framework that helps researchers to find existing proposals easily and to develop well-founded future work. To accomplish this, we propose a two-level taxonomy, and we describe the main contributions related to each field. Moreover, we provide a snapshot of the status of the publications in this field according to the ISI Web of Knowledge. Finally, some considerations regarding recent trends and potential research directions are presentedThis work was supported in part by the Spanish Ministry of Economy and Competitiveness under Grants TIN2014-56633-C3-3-R and TIN2014-57251-P, the Andalusian Government under Grants P10-TIC-6858 and P11-TIC-7765, and the GENIL program of the CEI BioTIC GRANADA under Grant PYR-2014-2S

    Modelado complejo de información lingüística en problemas de toma de decisión en grupo bajo incertidumbre

    El modelado de información lingüística en problemas de Toma de Decisión en Grupo (TDG) con incertidumbre y sus Procesos de Alcance de Consenso (PAC), se ha convertido en una línea de investigación de gran importancia dentro del ámbito de la toma de decisión. La mayoría de propuestas enfocadas al modelado lingüístico, se basan en el enfoque lingüístico difuso y emplean expresiones lingüísticas cercanas a la forma de pensar de los seres humanos para modelar la incertidumbre inherente en los problemas de decisión. Sin embargo, muchas de estas propuestas presentan limitaciones en términos de interpretación y/o precisión. En esta tesis doctoral, se ha propuesto un nuevo marco metodológico para el modelado y tratamiento de incertidumbre para problemas de TDG y PAC mediante expresiones lingüísticas complejas que permite modelar las opiniones de los expertos en este tipo de problemas.The modelling of linguistic information in Group Decision Making (GDM) problems with uncertainty and its Consensus Reaching Processes (CRPs) has become a very important research line in the field of decision making. Most of the proposals focused on linguistic modelling are based on the fuzzy linguistic approach and use linguistic expressions close to the way human beings’ thinking to model the uncertainty inherent in decision problems. However, many of these proposals have limitations in terms of interpretation and/or accuracy. In this doctoral thesis, a new methodological framework has been proposed for the modelling and treatment of uncertainty for GDM and CRPs problems by means of complex linguistic expressions that allow modelling the experts’ opinions in this type of problems.Tesis Univ.
