One of the rarest commodities is space. This applies in particular to warehouses with a traditional setup. Order picking from fixed racks continually creates empty spaces and means workers have to cover relatively large distances.

With order collection the goods are collected for further use, usually distribution. Plastic crates can be used for this. This collection bin then rotates between goods storage and the packaging department.

During a production process, semi-manufactured products are often produced. Semi-manufactured products often cover the same logistical route, within the company, but also outside.
