Description

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:
  • Add as part of reconfiguration specific ExplorationSpecification (probably in branch of org.fortiss.af3.exploration -> to be clarified with AD)
    • number of future time steps considered
    • length of a time step (in real-time)
  • Annotation in org.fortiss.af3.reconfiguration
    • RUL: ExecutionUnit -> double
    • 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)
