Estimate Data in the Future

You might want to estimate the number of events that will have occurred or the amount of non-event data (e.g., cost) that has been incurred at some point in the future. This estimation assumes that you do not plan to make any additional changes in your Asset or work process.

Steps

Access a Reliability Growth Analysis for which you want to estimate data in future.
In the left pane, select the Cumulative <Measurement> Plot tab.

The Cumulative <Measurement> Plot appears in the workspace.

Note: You can also estimate data in future via the Mean Time Between <Measurement> Plot, and <Measurement> Rate Plot tabs.
In the upper-right corner of the workspace, select Analysis Task, and then select Extrapolate.

The Segment Extrapolation window appears.

Note: If you have not yet extrapolated the analysis, the No Extrapolation option is selected.
If you want to estimate data by specific date, select Date, and then enter or select the date on which you want to know how many failures will have occurred.

Note: You can extrapolate by date only if your analysis data contains dates. If the analysis does not contain dates, the Date option will not appear, and you will not be able to extrapolate based on dates.

-or-

If you want to estimate data by specific time, select Time, and then specify the number of time units at which you want to know how many failures will have occurred.

Note: The date or time that you specify must be greater than the default date or time, which is the analysis end date or time.
Select OK.

The Cumulative <Measurement> Plot workspace appears, displaying the Cumulative <Measurement> plot with several lines added based on the extrapolation specification.
