Warranty Data
Analysis
- Enhanced in Version 7!
Weibull++’s popular Warranty Analysis module allows you to enter
sales and returns data to perform life data analysis and to generate
warranty forecasts. Extensively enhanced in Version 7, this utility now
provides:
- Choice of Data Entry Form: 1)
"Nevada" format with quantity shipped and quantity returned per
period 2) "Times-to-Failure" format with exact times-to-failure for
returned units or 3) "Dates of Failure" format with exact
manufacturing and return dates.
- Integrated Handling of
Non-Homogeneous Populations: You can define and analyze data from
different design iterations simultaneously and perform forecasts based
on mixed sales data.
- Option to Consider Warranty Length
in Forecasts: Specifying the warranty length allows the analysis to
take into account the possibility that failure data were not collected
beyond the warranty period and/or to exclude predicted failures that
fall outside the warranty period.
- Graphical Plots: You can generate a
variety of graphical plots to illustrate your warranty analysis and
forecasts, including Reliability vs. Time, Unreliability vs. Time,
pdf, Failure Rate vs. Time, Contour, Failures/Suspensions and Expected
Failures vs. Period.
- Detect Abnormalities: The
utility provides built-in analysis and control charts to monitor and
detect abnormal sales and/or return months.

Degradation
Data Analysis
- Enhanced in Version 7!
The Degradation Analysis module allows you to extrapolate the failure
times of a product based on its performance (degradation) over a period
of time. In addition to the Linear, Exponential, Power and Logarithmic
models, the Gompertz and Lloyd-Lipow models are now available for
degradation analysis in Version 7. It is easy to generate a Degradation
vs. Time plot for the analysis and to transfer the extrapolated failure
times to a standard folio for life data analysis.

Reliability Block Diagrams to Analyze Failure
Modes
- New in Version 7!
The Competing Failure Modes option has been a very popular feature among
Weibull++ users. The Reliability Block Diagram (RBD) feature that has
been added to Version 7 provides a huge leap forward in both flexibility
and analytical power. Now there is no limit to the number of failure
modes that you can consider and each mode can be analyzed individually
with the appropriate lifetime distribution. In addition, you can use the
flexible RBD interface (patterned after the intuitive BlockSim diagram
utility) to describe the reliability-wise relationships among the modes
(i.e. series, parallel, k-out-of-n) and thereby model the failure
behavior more accurately and realistically.
Using the exact algebraic reliability equation for the configuration
that you've defined, Weibull++ provides common reliability results and
plots at the click of a button. You can even consider the uncertainty of
the fitted parameters of each data set to calculate confidence bounds on
the overall reliability metrics!
