Determination of the overall equipment effectiveness for assembly systems on the base of product data

To enable traceability of faulty products it is necessary that product data, including the important parameters of the manufacturing process, be stored for the long-term. This product-related process and quality data usually amounts to very large quantities while at the same time it is only rarely used. Furthermore, for an increasingly large number of production systems designed for mass production, the Overall Equipment Effectiveness (OEE) is being applied as a standard for measuring their productivity. By incorporating the factors availability, quality rate and performance rate, the OEE represents a better measure for the efficiency of a production facility than just the availability. This paper deals with a new approach for a process-accompanying determination of the OEE for assembly systems based on the usage of in-process acquired product data. Thus, this approach is especially suitable for production systems that require complete traceability for the produced goods.
