The paper gives an introduction into the field of factory planning with the specific task of the evaluation of the logistics costs for an existing system with the help of VDI-4405 and the usage of Process Mining. The actual challenges in intralogistics are shown and is explained how in a traditional manner a material flow analysis can be performed. Based on these foundations a new concept for the incorporation of Process Mining into an existing material flow analysis workflow has been elaborated with the help of an industry 4.0 data driven monitoring concept. In a case study the planning efforts for an interview and type representative material flow modelling is then compared with the efforts needed to fulfil the same task with the help of Process Mining.
