To assemble a variety of products, a multi single assembly line,mixed model assembly line or a flexible assembly system (FAS) may be used. Past studies were concerned with the modeling, investigation and comparison of single and mixed model assembly systems, where the main transportation system was a continuous conveyor. According to new market demands, it is required to consider FAS, utilizing AGVs as the main automatic transportation system. In this research,traditional and flexible assembly systems are reviewed and compared.To compare these system criteria, such as stability to demand changes and balance of station workloads, the efficiency of material handling and the whole assembly system are considered. The assembly of two kinds of motorcycle is used as a sample case study. The result shows that a stable system (with little variation in terms of number of stations) having good performance measure values, is achieved when a flexible assembly system is employed.
