Function Wizard - Data Sources

Associated Data Sources

In Synthesis Workbooks in Weibull++/ALTA, RGA and BlockSim, you have the option to associate multiple data sources that can be used for any function that obtains data or results from an existing analysis. (To obtain results from a DOE analysis in Weibull++/ALTA, see DOE Analysis Report.)

When you create this type of function, you will have the option to use an index to specify which of the currently assigned default data sources will be used. For example, if you want to compare the reliability values calculated from two different analyses, you can use =RELIABILITY(Default1,1000) to get the result from the first default data source, and =RELIABILITY(Default2,1000) to get the result from the second default data source.

Although you will be prompted to associate the first data source when you create the report, you can add or change associated data sources for an existing report at any time.

Associating Data Sources

For Synthesis Workbooks, the Information panel (located on the right side of the window) shows which analyses are currently assigned as default data sources. To have the panel always display, click the pushpin icon into the vertical position.

To add or remove analyses, choose Home > Report > Associate Data Sources or click the icon in the Information panel.

The following picture shows the windows for Weibull++. Similar functionality is available in ALTA, RGA and BlockSim.

Note that:

Linking Multiple Data Sources with Different Time Units

In BlockSim, function results that are time-based (e.g., downtime, time to event, etc.) will be returned in terms of the System Base Unit (SBU) for the repository. However, in Weibull++/ALTA or RGA, each function result is returned in the units used by its data source. If you wish to compare the results from multiple data sources that use different time units, there are two possible scenarios:

Tip: If you want to keep the original analysis unchanged, you could create a copy of the data sheet, then convert the duplicate data sheet to use the new units.
