This page is only about the advantages / disadvantages of assembly line assembly compared to ...
* [[fixed station assembly]] and perhaps also
* [[parts streaming assembly]]

This page is not about specific types of [[assembly line assembly]] <br>
like covered here: [[Assembly lines in gem-gum factories]]

== Speed ==

The needed-motion-length per part-placed is more
* near to the scale of the input parts rather than
* near to the output parts.

This is because
* there is no need to travel far inside (and back out of) the [[build chamber]] for every single addition of an input part<br> This gives a gain in less-distance-needed-to-be-traveled on the order of the the [[branching factor]] B.
* More compact buildability due to spezialisation leading to further shortened travelshorter

== Specialization ==

Special purpose built assembly robotics can be faster and/or smaller than general purpose assembly robotics.

* less extra moves: no need for operations like tool-head changes
* more compact robotics: functionality can be [[semi hardcoding|semi hardcoded]] by cams&followers shims and wedged.

== Relation to [[part streaming assembly]] ==

Unlike assembly line assembly part streaming assembly ...
* needs a lot of space for streaming parts along the moving manipulators
* can be more general purpose programmable but not as much as [[fixed station assembly]] without losing its benefits (some planning ahead needed)

Like assembly line assembly part streaming assembly ...
* can give increased assembly speed (but not as much it seems – TODO to quantify)
* has the travel-distances-per-part-placed more near the input scale than the output scale

{{todo|Think about wether there are any cases where combining [[assembly line assembly]] and [[part streaming assembly]] makes dense??}}
