Created Dec 05, 2020 by Simon Barner@barnerMaintainer

Reconfiguration: Prediction metamodel

Failure probabilities: pred: ExT ->[0;1]

  • T = {1, …n} is a finite discrete set of time steps
  • Used to compute likelihood of each failure scenario

Implementation idea (in org.fortiss.af3.reconfiguration)

  • Annotation
    • RUL (Remaining Useful Live): ExecutionUnit ->double
    • Using the annotation in the formalization
      • Alternative 1: use ratio considered time step / RUL ("percentage of RUL used).
      • Alternative 2: convert considered time step to “real” failure probability (e.g. in Weibull distribution that is scaled with estimated RUL)
  • As two org.fortiss.af3.exploration.model.BackendSetting<T> (test depends on #4063 (closed))
    • number of future time steps considered
    • length of a time step (in real-time)
