      Este artículo propone el diseño y desarrollo de un planificador para la red de telescopios GLORIA. Esta red, cuyo principal objetivo es acercar los ciudadanos a la astronomía, está formada por 18 telescopios ubicados en cuatro continentes. Parte de la gestión de esta red se lleva a cabo por el planificador, que se encarga de recibir peticiones de observación de usuarios de usuarios y enviárselas a uno de los telescopios de la red. Para esto, necesita un algoritmo que decida el mejor telescopio, evitando ofrecer una petición a un telescopio que finalmente no pueda ejecutarla. Este artículo presenta dos algoritmos de decisión: el primero se basa únicamente en la predicción meteorológica, y el segundo emplea lógica difusa e información de cada telescopio. Ambos algoritmos fueron implantados en la red GLORIA. Los resultados obtenidos, así como una comparativa del rendimiento de ambos se presenta en este artículo. Así mismo, se detalla la arquitectura del planificador basada en una estructura híbrida distribuida-centralizada.

      This paper proposes the design and development of a telescope network scheduler for the GLORIA telescope network. This telescope network, which main objective is helping users to get involved in astronomy research, is composed by 18 heterogeneous telescopes located in different countries. These telescopes are managed by the scheduler to execute the observations requested by the users. A key module of this scheduler is the telescope decision algorithm which objective is to avoid serving an observation to a telescope that cannot execute it. This paper proposes two different algorithms: the first one is based on weather forecast, and the other one is based on fuzzy logic. Both algorithms were deployed and used into the GLORIA network, an analysis of the results and a performance comparative between both algorithm are shown in this paper. As well, the scheduler architecture based on a hybrid distributed-centralised schema is detailed.
