'''Stress-Strength Analysis with Parameter Uncertainty'''
#REDIRECT [[Stress-Strength_Analysis_in_Design_for_Reliability]]
 
Assume we are going to use stress-strength analysis to estimate the reliability of a component used in a vehicle. The stress is the usage milage distribution and the strength is the failure mile distribution of the component. The warranty is 1 year and 15,000 miles, which is earlier. The milage distribution per year is given the table below.

Please estimate the reliability of the component within the warranty period (1 year/15,000 miles).
 
 
'''Solution'''
 
First, we need to estimate the stress and strength distribution using the above data. The estimated stress distribution is given in the figure below.

The estimated strength distribution is given as:
