Quick Tour of Weibull++

Weibull++ offers the most comprehensive toolset available for reliability life data analysis, with support for all life data types and all commonly used product lifetime distributions.

Accelerated Life Testing (ALTA) and Accelerated Life Testing PRO (ALTA PRO) utilize powerful life-stress relationship models to design and analyze data from accelerated life tests.

Reliability Growth (RGA) supports all of the major reliability growth models and can analyze data from both developmental testing and fielded repairable systems. It also includes a comprehensive toolset for advanced reliability growth projections, planning and management.

These applications are also packed with tools for related reliability analysis such as degradation data analysis, stress-strength comparison, reliability test design and design of experiments (DOE). In addition, Weibull++ also supports warranty data analysis, non-parametric data analysis and recurrent event data analysis.

For life data and life-stress data analysis, you can use this application to answer a wide variety of questions such as:

• How many units do you need to test? How much test time? At which stress levels?

• Will the product meet the reliability requirement?

• What is the influence of different failure modes? How does accelerated stress affect life?

• Which design (or supplier) will be more cost-effective over time?

• How many units are likely to be returned under warranty?

• Is there an emerging reliability problem in the field? With a particular supplier? In a particular region?

• When will a crack, wear, etc. degrade to the point of failure?

• What is the typical time to repair? How effective are the repairs?

For growth data analysis, you can use this application to answer a wide variety of questions, such as:

• Will the product meet the MTBF goal? How much test time is required?

• How does the product perform across different test phases? At which phase will the product meet the reliability requirement? What is the initial MTBF?

• How do the test data compare to the reliability growth test plan?

• What failure modes should be fixed and when?

• What is the optimum growth maintenance strategy? When is the best time to schedule maintenance/overhauls?
