Autonomous transportation systems represent a significant use case for the implementation of industry 4.0. The transparency of logistics parameters, especially the replenishment time, can be increased and controlled efficiently compared to conventional material supply based on milkrun concepts. This article describes a systematic approach to ensure the process capability of the replenishment time for logistics processes based on autonomous transportation systems applying a six sigma approach. The case study has been performed in a real production environment in the automotive supplier industry.
