Simulation and scheduling of AGV based robotic assembly systems

Abstract

The paper presents a general discrete event simulation model developed in Siemens Plant Simulation software that controls AGVs in robotic assembly systems. All product assembly operations are inputs as graphs (trees). A methodology has been created that schedules the assembly operations on each workstation and schedules AGVs so that the overall manufacturing time is to be as short as possible. The system can control AGVs in real-time, handle arbitrary number and type of products and is prepared for stochastic events.
