FEATURES & BENEFITS Fully featured Weibull plots Life data analysis Reliability growth curves and planning Duane/Crow-AMSAA methodology Optimal replacement Test planning calculator Barringer process reliability Weibull statistics calculator Warranty cost analysis Best fit distribution Confidence intervals
Versatile toolset. Relex Weibull incorporates extra features to supplement the standard Weibull analytics. Some handy functions include a general statistical calculator, an optimal replacement wizard, and a test planning calculator. The Barringer process reliability function takes you step-by-step through the data collection process necessary for computing and improving the reliability of your process.

Weibull plots. Weibull results are presented in standard Weibull plot outputs. You can plot all data points for several data sets on one graph, along with the associated estimated distribution curves. You can optionally add in confidence intervals and the characteristic parameters of the resulting distributions.

Weibull techniques enable you to examine any type of failure data you have collected. You can use Weibull tools to effectively analyze all types of system life data, including mechanical, chemical, electronic, material, and even human failure data. You can then use your real-world field data to predict trends and analyze your system reliability. Relex ® Weibull provides full Weibull analysis capabilities in a powerful statistical tool wrapped in a friendly and flexible user interface. Relex Weibull has a broad range of applications and can be applied to any industry or process with ease. It moves the complexity of the statistical methodology into a powerful behind-the-scenes engine, allowing you to more accurately and efficiently analyze your life data.

Data distribution analysis. Once data has been collected, you can use Relex Weibull’s built-in distribution analyzer to determine which statistical distribution best fits your data. Relex Weibull supports the popular Weibull distribution, as well as a wide range of additional distributions such as Exponential, Normal, Lognormal, Gumbel, Rayleigh, and WeiBayes, to ensure that your analysis is as accurate as possible. You can select your distribution type or allow Relex to optimally determine it for you.

Reliability growth. One of the most significant features included in Relex Weibull is the ability to assess and evaluate statistics for reliability growth planning. Relex Weibull reliability growth features supports the widely accepted Duane/Crow-AMSAA methodology for performing reliability growth analyses. The Duane/Crow-AMSAA model can be used to track critical parameter rates such as warranty cost, outages, fires, and accidents.

The Relex Architect platform. Relex Weibull includes all the advanced features of Relex Architect’s robust, proven framework. A rich user interface is coupled with innovative features such as the invaluable Project Navigator for centralized Project control, the Relex Bar for customized one-click operations, the Task List for quick access to commonly used tasks, and data filtering for ultimate user control of data views. Comprehensive reporting capabilities include easy-to-use Report and Graph Wizards for complete user customization of output reports and graphs. Relex’s Import/Export Wizard enables you to transfer your Project data to and from Relex in a variety of popular formats, including Microsoft Excel ® and Access ® . Additionally, Relex Architect modules are built on a common database, for optimal product integration and data sharing capabilities.

Built for the enterprise. Relex’s Enterprise Edition supports the high performance, scalable needs of large user bases. Features such as support for Microsoft SQL Server ® and Oracle ® databases, permission based security, user and group roles, front end web interfaces, Relex Dashboard for a high-level overview of system metrics, audit trails for tracking data modifications, and customizable data connectors insure that Relex meets the needs of full scale, enterprise-wide teams.

Complete capabilities. Relex Weibull goes beyond analyzing data sets, augmenting these fundamental activities with a broad range of product-enhancing functions. The built-in test planning calculator offers the ability to do test planning based on parameters you define. The general Weibull statistics calculator provides a wide range of useful statistical functions that can expand your Weibull studies or can be used as a powerful, stand-alone statistical function calculator. The optimal replacement feature enables you to perform replacement analyses on your system. Relex Weibull also provides a Barringer process reliability analysis function for analyzing processes that have considerable opportunities for improvements. Relex Weibull augments its analysis capabilities by supporting the most commonly used parameter estimation methods including Benard, binomial, mean, Hazen, maximum likelihood (MLE), and modified maximum likelihood (MMLE). Additionally, Relex Weibull supports several methods for computing confidence intervals including modified Fisher matrix, likelihood ratio, binomial, and Monte Carlo (pivotal).
