Realistic Distributions from Field Data
The most realistic component / equipment failure rates are obtained by analyzing field failures or run to fail tests.
BQR offers three levels of analysis:
- Analysis of failure and maintenance logs of many components / equipment, calculation of rate and additional distribution parameters (beta for Weibull, sigma for Log-Normal…), accounting for effects of maintenance events on the component operational age
- Calculator for constant failure rate and confidence level of many components where the data is saved in a library and can be used together with additional component failure rate sources to calculate system failure rate
- Free calculator for constant failure rate and confidence level of a single component
