Reliability Metrics and Plots
Quick Calculation Pad for Important Reliability Metrics at the Click of a Button
The Quick Calculation Pad (QCP) provides a quick, easy and accurate way for you to obtain results for the most frequently asked reliability questions. This includes:
- Reliability or Probability of Failure
- Failure Rate
- Warranty Time for a given reliability
- B(X) Life
- Mean Life calculations (MTTF/MTBF)
The utility also returns the conditional reliability or probability of failure given the starting age.
Plots and Graphics to Showcase Your Analyses
Weibull++ continues to offer unparalleled plotting capabilities to demonstrate your analyses visually. You can generate graphs of Probability (e.g. Weibull plots), Reliability vs. Time plots, Unreliability vs. Time plots, pdf plots, Failure Rate vs. Time plots, Contour plots and 3-Dimensional Likelihood Function surface plots with the click of a button. In addition, Version 7 now includes histogram, pie and timeline charts to display failures/suspensions data. The Plot Setup allows you to configure the appearance of plot output and the software also provides a Chart Wizard to create your own custom charts. All plot graphics are metafiles that can be pasted or inserted into other reports and presentations.
Multiple Plot Sheets
The Multiple Plot Sheet makes it easy to compare analyses by automatically plotting the results for multiple data sets together in the same plot.
Side-by-Side Plots Utility
The Side-by-Side Plots utility allows you to view (and print) multiple plots for a given data set side-by-side. For example, you may want to show the Probability, Reliability, pdf and Failure Rate plots for a given analysis together in the same window. Alternatively, you may wish to compare the Probability or pdf plots for a given data set when analyzed with different distributions. Simply select the combination that meets your analysis/reporting needs.
RS Draw to Edit and Annotate Plot Graphics
You can use RS Draw, ReliaSoft’s integrated metafile graphics editor, to edit and annotate the plots generated by Weibull++. This utility allows you to insert text, highlight a point or line, mark the coordinates of a point, and much more!
Confidence Bounds for Parameters and Results
Weibull++ provides confidence bounds for all of the standard life data analysis parameters and results and also for many of the results from related analyses (such as warranty forecasts, recurrent event data analyses, etc.). In addition to the Fisher Matrix, Likelihood Ratio and Beta Binomial methods, Bayesian confidence bounds have been added in Version 7. You can choose whether bounds will be displayed and also specify the confidence level and type of bounds.
