Simulation of tandem and Re-Entrant manufacturing lines

Abstract

Modeling manufacturing systems is a necessary tool in the process of finding a way to analyze and improve design. Increasingly complex systems are now being modeled, and two such systems are the focus of this report. The Tandem and Re-Entrant systems allow for multiple part types to be sent through a single line of processing machines. The parts have different priorities which determine the order in which they are produced. The Re-Entrant system is unique because it produces a single part that is processed through the same machine line multiple times. As the part travels through the processing line, it loops back to the beginning at the end of every run as a higher priority part. These simulations were tested for their validity by running with different input parameters to see how the system reacted. These programs can be used in the future with more complex systems and the knowledge gained from the results of these simulations can be applied to improving these systems and maximizing their efficiency.
