Abstract

In an integrated Manufacturing Facility, consisting of various individual manufacturing cells, an automated material handling system (AMHS) - such as an Automated Guided Vehicle System (AGVS) - servicing each of cells plays a major role. In order to understand, and choose, the correct type of AGV system, simulation techniques can be used very effectively. In this paper, two different AGV Control Systems have been analyzed with computer simulation models. These animated graphic models also include details of all the individual process steps from the Wafer Sort operation through the Test processes of an IC Manufacturing Facility at Intel. The simulation model is used to analyze the behavior of the AGVS, as measured by the average AGV utilizations, AGV congestion levels, average AGV response times, as well as process characteristics such as Throughput Time through the line, Work in Process levels and overall product throughput through the line. The model has been used to recommend the proper AGV control logic, as well as the number of vehicles required.
