Introduction to Weibull++

ReliaSoft Weibull++ by HBM Prenscia is the industry standard in life data analysis (Weibull analysis) for thousands of companies worldwide. Accelerated Life Testing (ALTA) provides an intuitive and user-friendly way to utilize tremendously complex and powerful mathematical models for quantitative accelerated life testing data analysis. Reliability Growth (RGA) is a powerful software tool that allows you to apply reliability growth models to analyze data from both developmental testing and fielded repairable systems. In the development stage, the software allows you to quantify the reliability growth achieved with each successive design prototype and also provides advanced methods for reliability growth projections, planning and management. For systems operating in the field, RGA allows you to calculate optimum overhaul times and other results without the detailed data sets that normally would be required for repairable system analysis.

This application is part of the suite of ReliaSoft desktop applications, which offers intelligent integration between reliability program activities and tools, while simultaneously facilitating effective information sharing and cooperation between engineering teams of any size. For information about features that are shared by all (or most) of the ReliaSoft desktop applications, see the Databases and Projects, Desktop Application Interfaces and ReliaSoft Common Tools chapters.

Other ReliaSoft software by HBM Prenscia includes: BlockSim, Lambda Predict, XFMEA, RCM++, MPC, SEP web portal and XFRACAS.
