ALTA: Accelerated Life Testing Data Analysis Software Tool

Accelerated life tests... quantifiable resultsTM

Version 10 is now available. See what's new or download a free demo today!

Click to see a picture of the software interface...ReliaSoft's ALTA software provides an intuitive and user-friendly way to utilize tremendously complex and powerful mathematical models for quantitative accelerated life testing data analysis.

Quantitative accelerated life testing techniques in conjunction with powerful QALT data analysis methodologies give design and reliability engineers the power to significantly reduce test times, which can provide faster time to market, lower product development costs, lower warranty costs and other benefits!

Software Features

ALTA provides a comprehensive toolset for accelerated test planning and quantitative accelerated life testing data analysis, plots and reporting. The software tool is available in two versions and both provide a complete array of utilities for designing accelerated life tests, evaluating the fit of the model, calculating reliability metrics, generating plots and performing related statistical analyses.

ALTA Standard provides life-stress relationship models to analyze accelerated life test data with 1 or 2 constant stresses.

ALTA PRO offers advanced capabilities for analyzing accelerated life test data with up to 8 simultaneous stress types where stress is constant or varies with time!

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 addresses the subject of quantitative accelerated life testing data analysis (ALT analysis, QALT 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 useful methodologies to meet the specific challenges you face.

Applications and Benefits

Some of the potential applications and benefits for using quantitative accelerated life testing data analysis techniques and ReliaSoft's ALTA software tool include the ability to:

  • Understand and quantify the effects of stress (or other factors) on product life.
  • Design accelerated tests that will be the most effective to achieve desired objectives.
  • Significantly reduce the test time required to obtain reliability metrics for a product, which can result in faster time-to-market, lower product development costs and improved designs.
