Performance forecasts as feedback for schedule generation

Reactive Scheduling in Real Time Production Control

“…Performance trend forecasts, based on a regular sampling of statistics, are also considered as essential feedback information for schedule re-optimisation, and, thus, improving the schedule execution stability. This kind of feedback information is used in [86] for dynamic job-shop scheduling, and in [174] for PS in intelligent manufacturing systems. Real-time feedback based monitoring can solely perform a reliable comparison and evaluation of the scheduled and executed processes, analysis of the problem situation encountered (i.e., a deviation from the planned course of processes), and diagnosis based on a descriptive (behavioural) model of the current system state [146].…”
