Using Growth Data Folios

Weibull++’s growth data folio supports traditional reliability growth analysis, repairable systems analysis and reliability growth projections. The data type you select determines the type of analysis you can perform.

The basic steps for using a growth data folio are:

1. Add growth data folio

   Right-click the Growth Data folder in the current project explorer and choose Add Growth Data.

   

   In the setup window, select the desired data type. (See Reliability Growth Data Types.) Then click Next to set the units for values (hours, cycles, etc.) and other preferences. (See Creating a Growth Data Folio.)

   

2. Enter data

   Enter the data and use the control panel to specify the growth model and analysis settings. (See Growth Data Folio Control Panel for descriptions of all available settings.)

   

3. Analyze data

   Click the Calculate icon on the control panel.

   

   The Analysis Summary area displays the parameters of the growth model. Click the Detailed Summary icon to view more information.

   

4. View plots

   Click the Plot icon on the control panel to open the plot sheet. (See QCP Calculations and Plots for Traditional RGA.)

   

   To show the confidence bounds, right-click the plot, choose Show Confidence Bounds, and then set the desired type of bounds and confidence level.

   

5. Calculate metrics

   Click the QCP icon on the control panel to open the Quick Calculation Pad. (See QCP Calculations and Plots for Traditional RGA.)

   

   The following example shows the instantaneous MTBF with the lower one-sided 90% confidence bound.
