Physical Agents and RFID for the implementation of the Shop Floor Control on a Distribution Centre.

[ES] En la última década, la aplicación de la tecnología de sistemas multiagente para el control en planta ha generado gran expectación por parte de profesionales e investigadores. El uso de esta tecnología, por la propia definición de los agentes como: sistemas reactivos (capaces de responder ante cambios en el entorno), proactivos (generando iniciativas dirigidas a alcanzar sus objetivos), autónomos y con capacidades sociales (la toma de decisiones está consensuada), ha propiciado la aparición de gran cantidad de iniciativas. Lamentablemente, la mayoría de estas iniciativas se reducen únicamente a definiciones de agentes, declaración de intenciones o simulaciones, o bien constituyen propuestas demasiado ambiciosas, lo que ha impedido que la industria adopte este tipo de soluciones. Este artículo presenta una aproximación para la implementación de los agentes encargados del control en planta, conocidos como agentes físicos u holones, sobre una plataforma experimental que representa las instalaciones de un centro de distribución automatizado. Se ha tomado como punto de partida el concepto de holón, pero se ha adaptado de manera que la toma de decisiones tenga lugar en el controlador industrial. El trabajo se ha centrado en alcanzar una toma de decisiones en planta inteligente. Se definen dos tipos de agentes y se ha modelado, mediante redes de Petri, la forma en la que interaccionan estos agentes en la toma de decisiones que surgen en el funcionamiento de una planta inteligente. Finalmente los modelos se han implementado sobre autómatas programables.[EN] The application of the multi-agent systems technology for shop-floor control has generated great expectations among professionals and researchers in the last decade. The use of this technology conveys, by the definition of the agents, reactive systems (able to respond to changes), proactive systems (their behavior is oriented towards the achievement of predefined objectives), autonomy, and social skills (consensual decision making), causing the emergence of many initiatives. Unfortunately, most references on this field are mainly concerned with: the definition of agents, statements of intent, simulations or rather ambitious proposals; which prevents industry from adopting this technology.This paper presents an approach to implement the agents in charge of the shop floor control, known as physical agents or holons, on a test bench that represent the installations of an automated distributed center. The concept of holon has been adapted to keep the decision making in the industrial controller. The work is focused on reach an intelligent decision making at the shop floor. For what, two kind of agents have been defined, and the decision makings at shop floor have been modelled by means of Petri Nets. Finally, models have been implemented over programmable logic controllers.Este trabajo ha sido desarrollado con el respaldo del Ministerio Español de Economía y Competitividad mediante la ayuda de referencia DPI2012-35227 al proyecto de título: “Sipail: Seguimiento Integral en Producción, Automatización Industrial y Logística”.De Las Morenas, J.; García, A.; Martínez, F.; García Ansola, P.
