Solution Reliability Evaluation Of Engineering Systems By Roy Billinton And Link

The primary work you are referring to is the seminal book "

The methodology developed by Roy Billinton and R.N. Allan provides a systematic approach to quantifying the reliability of complex engineering systems. Unlike basic "pass/fail" testing, their approach uses probabilistic methods to predict system performance over time. Their framework is the industry standard for power systems, telecommunications, and pipeline networks, allowing engineers to balance cost against the risk of failure.

Not more generators – just a faster, redundant switch. and pipeline networks

Billinton emphasizes that a solution is only as reliable as its weakest assumption. For the standby system: The primary work you are referring to is
