Warranty Data Analysis
Weibull++’s popular Warranty Analysis module allows you to enter sales and returns data to perform life data analysis and to generate warranty forecasts. Extensively enhanced in Version 7, this utility now provides:
- Choice of Data Entry Form:
- "Nevada" format with quantity shipped and quantity returned per period
- "Times-to-Failure" format with exact times-to-failure for returned units
- "Dates of Failure" format with exact manufacturing and return dates
- Integrated Handling of Non-Homogeneous Populations: You can define and analyze data from different design iterations simultaneously and perform forecasts based on mixed sales data.
- Option to Consider Warranty Length in Forecasts: Specifying the warranty length allows the analysis to take into account the possibility that failure data were not collected beyond the warranty period and/or to exclude predicted failures that fall outside the warranty period.
- Graphical Plots: You can generate a variety of graphical plots to illustrate your warranty analysis and forecasts, including Reliability vs. Time, Unreliability vs. Time, pdf, Failure Rate vs. Time, Contour, Failures/Suspensions and Expected Failures vs. Period.
- Detect Abnormalities: The utility provides built-in analysis and control charts to monitor and detect abnormal sales and/or return months.
Degradation Data Analysis
The Degradation Analysis module allows you to extrapolate the failure times of a product based on its performance (degradation) over a period of time. In addition to the Linear, Exponential, Power and Logarithmic models, the Gompertz and Lloyd-Lipow models are now available for degradation analysis in Version 7. It is easy to generate a Degradation vs. Time plot for the analysis and to transfer the extrapolated failure times to a standard folio for life data analysis.
Event Log Interface
New in Version 7, Weibull++ now provides a specialized folio designed specifically to capture data in an event log format (commonly used in the Machine Tools and other industries). This data entry sheet captures the type of event, the date/time when the event occurred and the date/time when the system was restored to operation. The software then converts this information to time-to-failure and time-to-repair data that can be analyzed with life data analysis techniques. The folio provides a number of options to tailor the analysis to fit your particular requirements, including the ability to define shift patterns, consider unique system IDs, perform the analysis at the system, subsystem, assembly or component level, etc. You can also export the results to BlockSim for system reliability, maintainability and availability analyses.
