ReliaSoft Weibull++

ReliaSoft’s Weibull++ software tool is the industry standard for life data analysis worldwide. The software utilises multiple lifetime distributions (including all forms of the Weibull distribution), with a clear and concise interface designed specifically for reliability engineering.

Overview

Weibull++ software helps you understand and communicate how a product will perform over time, including the ability to:

  • Compare suppliers or designs based on reliability.
  • Demonstrate that an item meets specified reliability.
  • Make predictions about performance during the useful life (or warranty) period.
  • Use plots and other reports to effectively communicate performance estimates to management.

Weibull++ is the most comprehensive toolset available for reliability life data analysis, calculated results, plots and reporting, with support for all data types and all commonly used product lifetime distributions. This includes the Weibull model and the mixed Weibull model as well as the Exponential, Lognormal, Normal, Generalized Gamma, Gamma, Logistic, Loglogistic, Gumbel and Weibull-Bayesian models.The software also contains multiple tools for related reliability analyses, such as warranty data analysis, degradation data analysis, non-parametric data analysis and recurrent events data analysis.

With the Weibull++ 7 Developer Edition, you can also integrate the entire Weibull++ interface or selected calculation and plotting engines from the Weibull++ software into your own custom designed applications.

Life Data Analysis Options

All Types of Data
Weibull++ supports Complete, Right Censored (Suspended), Left Censored, Interval Censored and Free-Form data, entered individually or in groups. A specialised 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.

Outputs

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.

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 and equation solvers.

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 Events 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.
