Weibull++ Product Features
![]()
Weibull++
is the industry standard in life data analysis (Weibull analysis)
for thousands of companies worldwide. The software performs life
data analysis utilizing multiple lifetime distributions (including
all forms of the Weibull distribution), with a clear and concise
interface geared toward reliability engineering. The software
provides a complete array of data analysis, plotting and reporting
tools for standard life data analysis (Weibull analysis) with
integrated support for a variety of related analyses.
All the options you need for life data analysis (Weibull analysis)
- All Types of Data: Weibull++ supports Complete, Right Censored (Suspended), Left Censored, Interval Censored and Free-Form data, entered individually or in groups. A specialized interface to analyze event log data is also available.
- All Major Lifetime Distributions: The software supports data analysis with the 1, 2 and 3 parameter Weibull, Mixed Weibull, 1 and 2 parameter Exponential, Lognormal, Normal, Generalized Gamma, Gamma, Logistic, Loglogistic, Gumbel and Weibull-Bayesian lifetime distributions. The Distribution Wizard automatically performs goodness-of-fit tests to help you select the most appropriate model for each data set.
Results at the click of a button and unparalleled plots and graphics
- Parameter Estimation and Calculated Results: Weibull++ supports both Rank Regression and Maximum Likelihood Estimation (MLE) for parameter estimation. Integrated utilities quickly return calculated results (such as reliability given time and BX life) based on the data analysis and your inputs. Confidence bounds are available for all parameters and calculated results.
- Plots and Automated Reports: The software automatically generates a complete array of reliability plots, with customizable settings. Plots are metafile graphics that can be annotated and used in your reports and presentations. Automated report generation is also available.
A complete array of related analyses
- Warranty Analysis: Perform life data analysis and make warranty projections based on sales and returns data, entered in a Nevada, Times-to-Failure or Dates of Failure format.
- Reliability Block Diagram: Use Reliability Block Diagrams (RBDs) that are integrated with calculated data folios to analyze competing failure modes and perform other system analyses.
- Recurrent Event Data Analysis: Use parametric or non-parametric methods to analyze events that are dependent and not identically distributed (such as repairable system data) and/or to model the number of occurrences of an event over time.
- Degradation Analysis: Use the Linear, Exponential, Power, Logarithmic, Gompertz or Lloyd-Lipow models to extrapolate the failure times of a product based on its performance (degradation) over a period of time.
- Non-Parametric Life Data Analysis: Use Kaplan-Meier, Simple Actuarial or Standard Actuarial techniques for non-parametric life data analysis.
- SimuMatic: Automatically perform large quantities of analyses on simulated data sets in order to investigate various reliability questions, including confidence bounds, testing scenarios, etc.
- Design of Reliability Tests: Determine the appropriate sample size, test duration or other variables for reliability demonstration tests.
Additional tools and wizards
- Weibull++ provides many additional tools and wizards designed to streamline, enhance and supplement your analyses. These include spreadsheets for custom analyses, statistical comparison wizards, equation solvers, and much more!
