## What is Reliability Analysis?

Weibull 2-parameter reliability analysis. The application takes as input the results of a reliability testing campaign (failures & usage metrics e.g. hours, Km, etc) and calculates the Weibull distribution parameters which fit the failures. This produces the model for reliability calculation versus time. The methodology used is Linear Rank Regression. Currently the application doesn't consider suspensions during testing. This will be accommodated in future release.
