The purpose was to analyse the income variation of the 13 top clubs of Deloitte Football Money League Report (2019) as well as the variation of the perceived value of their squad, obtained from the website www.transfermarkt.es during 9 seasons. Friedman's two-way analysis by ranges of selected samples and Wilcoxon W tests were used to measure the evolution and relation among the clubs’ income and perceived value of players. The income of clubs was deflected according to inflation (CPI: 2016) and market value was adjusted to a 20 players squad. Market value and income have a significant positive variation from one year to the next (p = .000). We found differences between both variables only in the last 2 years on the period analysed (2011-2019). Market value has suffered an increase higher than expected. This fact should make football managers reflect on how to control constant inflation in the transfer market.

The aim of this paper is to analyse different interactions of the variables (age, position, or quality of the team and the league) and the crowdsourcing Transfermarkt values of male players in the top European leagues. All players (n = 2259) in the five most highly valued European leagues&mdash, Spain, England, Italy, France, and Germany&mdash, from the 2017/2018 season were included in this study. Data were retrieved from the open-source football database (Transfermarkt). The present economic value (VPRESENT) and maximum economic value (VMAX) of all players with professional contracts were registered. Regression analysis evidenced a significant influence of the level of the team, the birth month, the league, the playing position and the age of the player on mean and maximum economic value (p &lt, 0.05). This analysis confirms that the players participating in the UEFA Champions League, Premier League teams, playing as attacking midfielders, and born in the first quarter of the year are the most economically valued in terms of both current value (R2 of 0.33) and maximal value (R2 of 0.36). Therefore, international football entities must take into account the financial balance between competitions&mdash, and not only at the domestic level, as the attractiveness and balance of European competitions may be directly affected.

El proceso de suministro directo a la línea de ensamble de componentes, sub-ensambles y sistemas ha sido y continúa siendo uno de los grandes retos logísticos de industrias altamente competitivas como la automotriz, la aeroespacial y la electrónica. La dificultad deriva del interés de las empresas por sincronizar efectivamente la entrega de los suministros con el programa de producción. Con el fin de medir la sincronización del proceso de suministro, se detectó que el binomio tiempo-costo ofrece una buena representación del nivel de sincronía que existe entre las exigencias del ensamblador y su proceso de producción, y las del proveedor y su capacidad de respuesta. De este modo, el factor de Confiabilidad, midió el nivel de garantía de no-disrupción en la sincronía del proceso. Así, con el propósito de establecer una solución al reto del análisis de la confiabilidad, este proyecto de investigación se centró en el desarrollo de un modelo dinámico del sistema de abastecimiento Justo en Secuencia tomando como base el caso de una empresa líder a nivel mundial en la prestación de servicios logísticos a la industria automotriz. Dada la alta estandarización de los procesos en empresas de ensamble, los resultados de la presente investigación son generalizables a otras industrias dentro del mismo sector, como la aeroespacial y la electrónica principalmente.
