This is a versatile, powerful and user friendly reliability analysis software package. The software consists of two modules; a life data analysis module and a maintenance optimization module. Data is easily entered with the specialized data entry grid which allows up to 2 billion data points.   All graphics can be customized with easy to use dialog tabs. When your analysis is complete, use the report writer to create custom output in a format compatible with major word-processors.

Life Data Analysis

This module is capable of estimating the distribution parameters for the

  • Weibull distribution,
  • normal distribution,
  • lognormal distribution, and
  • exponential distribution

The parameters of each distribution can be estimated using a variety of techniques, including

  • maximum likelihood (MLE),
  • probability plotting,
  • hazard plotting, and
  • moment matching

Some of the powerful features of this module are Bayesian estimation, zero-failure test planning, confidence limits for estimated parameters, confidence limits for reliability, confidence limits for percentiles, support for the 3-parameter Weibull distribution, including confidence limits for the location parameter, support for complete data, singly censored data, multiply censored data, and grouped data, graphical and statistical goodness-of-fit tests.

Another great feature of this module is the estimation screen. Use the estimated parameters to compute confidence limits for the time to fail and reliability; no more interpreting from graphs without enough resolution!

Maintenance Optimization

The maintenance optimization module contains three algorithms for the optimization of maintenance actions. The optimization of preventive maintenance, the optimization of inspection schedules, and the optimization of predictive maintenance. Optimum schedules are based on the cost of maintenance and time to fail data.
