Packing and Shipping Cardboard Tubes
Spiralpack - Manipulados de Papel, S.A. is one of the main Iberian peninsula players in the production of standard and high performance cardboard tubes. This company attended at 101st European Study Groups with Industry (ESGI) to address the following questions concerning their packing and shipping processes: Given an order for a certain tube specification, possibly with a grouping request, what is the maximum number of tubes that can be packed inside a given container (usually the truck space) and how should they be positioned? Given several pallets of tubes, what is the most efficient way to arrange them in a container? In this work we show an industrial mathematics approach to these challenges, as well as some insight on the software developed to help Spiralpack addressing those questions.
