If the fault tree model contains a time series, DPL provides an additional output option of a Time Series Percentiles graph which displays a set of percentiles (10th, 50th and 90th, by default) of the top node over time. To generate a time series percentiles graph, DPL calculates the value of the top node of the fault tree over a specified set of time periods and determines the selected percentiles of the value in each time period. If the fault tree is incorporated into a decision model with uncertainty, the percentiles will often be different. However, if the fault tree is not embedded in a decision model or is embedded in a decision model with no uncertainty, then the percentiles in each time period are the same and are equal to the calculated value of the node.
