There is hardly any detailed knowledge available on how to manage the design process of a packaging line. A packaging line is a sequence of a lot of different machinery with a multitude of parameters. Within the machinery there are buffers. Normally so-called V-curves are being used to set the speed over the line. The design of the packaging has a very strong correlation with the performance of packaging line, but this is unknown or neglected in practice. These design processes can be optimised in many ways.
