Event Tree Results Window
The Event Tree Results window displays a table with calculation results for the branches (event sequences) in the active event tree. All columns are display-only. Before a result is calculated, number signs (#.#) are shown. After a result is calculated, values are shown. For more information, see Calculating Event Tree Results.
The following table provides column descriptions. All calculated results are shown as probability values. Results are updated each time the event tree is calculated.
Column
Description
Branch Number
The number of the branch in which the logic for the event sequence, consequence, and results are shown.
Branch
The unique identifier assigned to the branch. While an identifier is assigned to the branch when it is inserted, you can change it to any unique value. The format for the assigned identifier is specified by Event Tree Branch Identifier, which appears under Identifiers in the System file properties. For more information, see Identifiers System File Properties.
Sequence
The sequence of events in the branch using the event codes as shown in the Event Tree Columns table.
Consequence
The consequence of the sequence. For consequences to show, you must have assigned them to branches on the Consequences pages in Properties windows. For more information, see Branch Properties.
Frequency
The frequency calculated for the branch.
Unavailability
The unavailability calculated for the branch.
Unreliability
The unreliability calculated for the branch.
Availability
The availability calculated for the branch.
Reliability
The reliability calculated for the branch.
