According to one embodiment, an availability analysis tool includes executable code that is operable to calculate an availability value for a system having a number of operational units. The executable code may receive one or more reliability metrics for each operational unit and designate one or more reliability metrics for at least spare unit associated with the operational unit to be similar to the one or more reliability metrics. An availability value for the system may be calculated according to the reliability metrics of the operational unit and its associated at least one hot or cold spare unit. The executable code may then output this calculated availability value to the user interface. |
