Analyzing Reliability for Non-Repairable Systems

 

See how to:

• Determine product life (Life Distribution) for situations with or without multiple failure causes
• Analyze time-to-event data to determine the lifespan of a product.
• Determine when a certain percentage of a product will fail or what percentage will fail by a certain time (or other measure of use)
• Examine Life Distribution 
  • Interpret Sample Output and Event Plots
  • Compare Nonparametric, Lognormal, Weibull, Loglogistic, Frechet, Normal, SEV and Logistic distributions
  • Interpret Parametric statistics and Covariate Metrics
  • Evaluate AICc and BIC
  • Use JMP Pro Profilers (Distribution , Quantile, Hazard and Density Profilers) to help analyze reliability properties
• Use Accelerated Life Tests on test units at accelerant conditions and then extrapolate back to a standard condition
• Analyze impact of degradation for substances that change potency or increase impurities over time
• Perform Destructive Degradation Analysis for situations where identifying the Critical to Quality metric requires destruction of the test sample
• Perform Stability Studies for new products
