The choice of which material feeding system apply to feed an assembly line, covers a main role in increasing the process efficiency. This choice must be weighted, considering both the industry intrinsic features and the productive environment under consideration. This thesis makes an overview about High-Mix and Low-Volume productive environments, which, being characterized by a great number of product variants, have to deal with many different components feeding the assembly lines. Especially in this productive environment, the practice of delivering the components to the assembly station is of critical importance in order to avoid the excessive increase in border of line (BOL) storage space and avoid useless activities for the operators.
