Simulación por medio de eventos discretos para una línea flexible de cabezas de motor. by Andrade Gutiérrez, Edgar Steff

“…La utilización de la manufactura virtual es una gran herramienta para modelar y analizar la logística de producción de sistemas complejos como altamente aleatorizados, complicados y discretos, los cuales pueden ser difíciles de estudiar de la manera tradicional. Se introduce en este trabajo la optimización de una línea flexible de cabezas de motor donde se modelan y se analizan los sistemas lógicos de producción, eficiencia de trabajo, estadística de capacidad de producción de manera efectiva y utilización mediante el software Plant Simulation; esta plataforma trabaja por medio de la simulación de eventos discretos siendo posible representar cada variable que constituye la línea y por medio de esta manera ofrecer una guía para la optimización de la logística de producción y toma de decisiones científicas. …”
