RESUMENEn un mundo altamente dinámico, debido a los cambios tecnológicos, económicos, políticos y sociales en el entorno, se ha reconocido que los sistemas productivos desempeña un papel fundamental en la competitividad de una organización. En esta investigación se plantea la integración del pensamiento esbelto en la gestión de un sistema de producción mediante la técnica de simulación de eventos discretos empleando redes de Petri como metodología de apoyo en el proceso de toma de decisiones. La toma de decisiones en un sistema productivo esbelto es un proceso complejo, esto debido a sus características estáticas (estructurales), dinámicas (operacionales) y los desperdicios que se presentan. En el trabajo se diseñan un conjunto de estructuras que representan distintas fases en un proceso productivo de neumáticos y se demuestra que un modelo empleando la metodología de redes de Petri ayuda a tener una eficaz y eficiente toma de decisiones para la eliminación de desperdicios, esto gracias a las propiedades para modelar eventos discretos y analizar el comportamiento dinámico del sistema. Finalmente la fase de simulación permite analizar un conjunto de parámetros a través de un indicador sistémico OEE (Eficiencia General de los Equipos), y demostrar que la implementación en conjunto de métodos, técnicas y herramientas esbeltas genera sinergia en el sistema.Palabras clave: Sistema de producción, producción esbelta, redes de Petri, simulación de eventos discretos, eficiencia general de los equipos. ABSTRACT In a highly dynamic world, due to technological, economic, political and social changes in the environment, it has been recognized that the production systems play a critical role in the competitiveness of an organization. In this research the authors propose the integration of lean thinking in managing a production system using the technique of discrete event simulation using Petri nets as the support methodology in the process of decision making. Decision making in a lean production system is a complex process because it has static (structural) and dynamic (operational) characteristics and a set of waste presented in it.This paper presents the design of a set of structures that represent different stages in a production process of tires and that is it possible to prove that the design of a model, using the methodology of Petri nets, helps to have an effective and efficient decision making for waste disposal, this thanks to the properties of such nets to model discrete events and analyse the dynamic behaviour of the system. Finally the simulation allows analysing a set of parameters through a systemic indicator OEE (Overall Equipment Efficiency) and demonstrate that the implementation of methods, techniques and tools proposed in the lean production theory generate synergy in the system.
