Industrie 4.0: Using Cyber-physical Systems for Value-stream Based Production Evaluation

This paper introduces a comprehensive method to examine and evaluate a production system using the information of the digital representations. By including order-specific information, such as the product price and production costs, a value stream based evaluation of each production stage can be generated and visualized with very little effort. The proposed modelling technique for machines, storages and transportation systems enables the application of this concept for highly automated production systems as well as shop fabrication. A modified method of the comprehensive value stream evaluation is applied for a use case, showing the general procedure and advantages.
