Reliability Characteristics of a Non-repairable System

The reliability characteristics of a non-repairable system include:

• Transient/Time-dependent Indices:

◦ Reliability, R(t).

◦ Unreliability, F(t).

◦ Individual state probabilities, PI(t).

◦ Time-specific failure frequency, v(t).

◦ Frequency of visits to a particular state at time t, vI(t).

◦ Time-specific capacity/reward, C(t) (see Expected Capacity or Reward).

• Steady-state and Asymptotic Indices:

◦ Expected time spent in a particular state before reaching a failed (absorbing) state.

◦ MTTFF (Mean Time To First Failure) or MTTF (Mean Time to Failure).
