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. Built by reliability engineers for reliability engineers, this package continues to raise the bar for statistical analysis software for reliability applications.

Software Features

Weibull++ provides the most comprehensive toolset available for reliability life data analysis, calculated results, plots and reporting. The software supports all data types and all commonly used product lifetime distributions (including the Weibull model and the mixed Weibull model as well as the Exponential, Lognormal, Normal, Generalized Gamma, Gamma, Logistic, Loglogistic, Gumbel, Bayesian-Weibull and Competing Failure Modes).

The software is also packed with tools for related reliability analyses, such as warranty data analysis, degradation data analysis, non-parametric data analysis, recurrent event data analysis and reliability test design.

Synthesis Integration

With integration into the Synthesis Platform, analyses are now stored in a centralized database that supports simultaneous access by multiple users and shares relevant reliability information between Synthesis-enabled software tools. For enterprise-level repositories, both Microsoft SQL Server® and Oracle® are supported.

Available Training

ReliaSoft offers a three-day training course that specifically addresses the subject of reliability life data analysis (Weibull analysis) and related techniques. By combining a solid theoretical foundation with practical application examples and hands-on software training, this course will give you the knowledge and skills you will need to successfully apply these important reliability analysis techniques.

Application Examples

The Weibull++ software provides an extensive array of tools to help you understand and communicate how a product will perform over time. Some of the many useful applications include 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.
