La Táctica deportiva y la toma de decisiones

Este libro recoge las conferencias de las IV Jornadas de la Cátedra de Deporte y Educación Física de la UdG y I Seminario Internacional de táctica y técnica deportiva, dedicadas a "la táctica deportiva y la toma de decisiones ". En el planteamiento de este libro el lector encontrará, fundamentalmente, ideas y reflexiones alrededor del proceso de la toma de decisiones en los deportes colectivos. Desde nuestro punto de vista, este tema es especialmente trascendente en la comunidad científica deportiva en los últimos años. Desde la publicación del estudio de F. Mahlo (1969) sobre el acto táctico en el juego, el interés por comprender y descifrar los mecanismos subyacentes de la toma de decisiones en el deporte ha aumentado año tras año y en la actualidad es un tema de gran calado científico y práctico. Nuestro deseo es que el lector pueda encontrar en estas páginas, elementos de reflexión teórica y contenidos de estudios científicos interesantes; y esto tiene que ayudar, a todos aquellos que estamos preocupados por la investigación y el entrenamiento deportivo a mejorar el comportamiento táctico de nuestros deportistas

Searching for consensus in ahp-group decision making. A bayesian perspective

This paper sets out to identify the initial positions of the different decision makers who intervene in a group decision making process with a reduced number of actors, and to establish possible consensus paths between these actors. As a methodological support, it employs one of the most widely-known multicriteria decision techniques, namely, the Analytic Hierarchy Process (AHP). Assuming that the judgements elicited by the decision makers follow the so-called multiplicative model (Crawford and Williams, 1985; Altuzarra et al., 1997; Laininen and Hämäläinen, 2003) with log-normal errors and unknown variance, a Bayesian approach is used in the estimation of the relative priorities of the alternatives being compared. These priorities, estimated by way of the median of the posterior distribution and normalised in a distributive manner (priorities add up to one), are a clear example of compositional data that will be used in the search for consensus between the actors involved in the resolution of the problem through the use of Multidimensional Scaling tools

Group preference structures in AHP–group decision making

This paper presents a procedure that allows us to determine the preference structures (PS) associated to each of the different groups of actors that can be identified in a group decision making problem with a large number of individuals. To that end, it makes use of the Analytic Hierarchy Process (AHP) (Saaty, 1980) as the technique to solve discrete multicriteria decision making problems. This technique permits the resolution of multicriteria, multienvironment and multiactor problems in which subjective aspects and uncertainty have been incorporated into the model, constructing ratio scales corresponding to the priorities relative to the elements being compared, normalised in a distributive manner (wi = 1). On the basis of the individuals’ priorities we identify different clusters for the decision makers and, for each of these, the associated preference structure using, to that end, tools analogous to those of Multidimensional Scaling. The resulting PS will be employed to extract knowledge for the subsequent negotiation processes and, should it be necessary, to determine the relative importance of the alternatives being compared using anyone of the existing procedures
