downtime of one failure within a storm cycle

⚠ Contributed draft — proposed through this site, not yet reviewed by a human. Not part of the published database.

The downtime caused by a single failure — failure k of type j on turbine i in storm cycle s — split into the part that falls inside the storm and the part that falls inside the catch-up period after it, each term restricted to its own period. Equation (4-20) in Great Expectations, which the aggregated downtime models sum over.
