Allocation action | The way in which availability is allocated. Choices are: • Specify Goal — When selected, the desired availability for the system or subsystem is entered. Availability, allocated becomes available so that you can enter the goal for the parent assembly. • Perform Allocation — When selected, availability is allocated equally for all subsystems. This choice is invalid for the top-most assembly. |
Availability, allocated | The availability goal for the parent assembly, which is generally the top-most assembly (system). |
MTTR specified | MTTF values are obtained for the subsystem from the MTTR column in the System Tree Items table. Only specified MTTR values are used to compute failure rate allocations. |
