Weibull++ SimuMatic

Weibull++ SimuMatic generates multiple data sets using Monte Carlo simulation. (See Weibull++ Monte Carlo Utility for information about how each data set is generated.) It then analyzes each data set individually (e.g., to find the reliability at a specified time) and the group of data sets as a whole (e.g., to find the average reliability at a specified time across the data sets).

To access Weibull++ SimuMatic, choose Insert > Tools > Weibull++ SimuMatic.

The setup window will appear. Follow the steps outlined below to generate and analyze the simulated data sets.

Note: Assuming that all the generated data sets have calculated parameters, the software will calculate the demonstrated life by taking each data set and solving for the time at which a product with that data set's distribution would have the specified reliability. It will then order these time values to find the time value that corresponds to the specified confidence level. For example, if you enter 85 for the target reliability and 90 for the confidence level, the software will, for each data set, solve for the time at which a product with that data set's distribution would have a reliability of 85%. It would then order the calculated time values and locate the value in the 10th percentile, which is reported as the 90% lower one-sided confidence bound for the demonstrated time.
