The automatic identification of workpieces is a compulsory step towards the Digital Twin and for a consistent life cycle file of products. Because different technologies exist, companies often face the challenge to find the right solution which meets their requirements. Especially the high level of prominence of some technologies lead to premature decisions without a profound selection process. This in turn might lead to sub-optimal solutions in the end. In order to support especially industrial companies in this process, a selection algorithm for Auto-ID technologies was developed as part of an industrial project at the department Factory Planning and Factory Management of TU Chemnitz. The selection process has been implemented in a Microsoft Excel-based tool.
