Logger

  • 2 types: summarized logger, time logger

    • for each logger, there is the possebility, to log the summarized kpi over the complete production time or every x seconds (time intervall)

      • the results of the time intervalls, where saved in an extra sub folder

  • for each type, each instance is logged and also an average of the instances is calculated

important: Only tasks with the logging type: “logging” are considered

the kpi’s are based on:

  • A Hierarchical structure of key performance indicators for operation management and continuous improvement in production systems

    • Ningxuan Kang,Cong Zhao,Jingshan Li &John A. Horst, 2016
