Assembly lines

Mass production systems are usually organized in assembly lines. The assemblies pass by on a conveyor, or if they are heavy, hung from an overhead monorail.

In a factory for a complex product, rather than one assembly line, there may be many auxiliary assembly lines feeding sub-assemblies (i.e. car engines or seats) to a backbone "main" assembly line. A diagram of a typical mass-production factory looks more like the skeleton of a fish than a single line.
