Nowadays production companies are in a difficult situation since batch sizes are decreasing, the number of product variants is growing, and the demand is difficult to forecast. New technologies enable to design more complex production systems capable of handling these challenges, but these “Industry 4.0 solutions” are often very expensive and hard to implement. In Bosch Power Tool Ltd. (Hungary), a flexible manufacturing concept was implemented, which enables to produce efficiently even with batch size one, requires much less space from the shop floor, prevents disruptions in production, and last but not least realized in from a relatively small budget. The concept introduced in this paper can be used as a best practice for manufacturing companies facing similar challenges.
