METHOD AND SYSTEM FOR ENHANCING TRACEABILITY IN A PRODUCTION LINE BY CREATING A TIME-BASED FINGERPRINT

摘要

The present invention relates to and a system for linking item parameters of items processed in a production line comprising a plurality of measuring devices configured to measure item parameters. The method comprises retrieving a time series of time stamps for each measuring device indicative of when an item passed the respective measuring device. Each time stamp is associated with a measured item parameter value. A set of time differences are determined between consecutive time stamps for each of the time series of time stamps. Each time difference is associated with a time stamp. Correlating subsets of time differences associated with at least two measuring devices. When the subsets of time differences match, associating the corresponding time stamps from the matching subsets of time differences with each other. The associated time stamps are stored in a data storage device.
