By modeling these phases mathematically, the authors provided a framework for predicting when maintenance should occur and how long components would last.
Do you have enough capacity this instant ? For a power plant: Are there enough working generators to meet current demand? For a data center: Is there enough UPS battery to ride through a 5-second voltage sag? By modeling these phases mathematically
This involves building a mathematical model (usually an event tree or fault tree ) that maps how component failures combine to cause system failure. For a simple system, this is a series/parallel reduction. For a complex one, it requires Minimal Cut Set theory. it requires Minimal Cut Set theory.
