Application of Weibull and KM Analysis to Determine Failure and Survival Rates in Automobile Industry using R

This project focuses on the automobile vehicle, automotive component failure detection based on failure modes using Weibull analysis and other survival analysis techniques.

Detailed attention is paid to three areas:

• Overall failure rates are described statistically first, and data cleaning and definitions of ‘failed’ data within spell period are made.

• Kaplan-Meier life curves and Nelson Allen Curve are used to compare the failure mode reliability over time and explore factor related to the vehicle failure.

• Weibull regressions, with three parameters, are applied to fit real-world reliability data from different test conditions to analyze the vehicle failure.

In addition to the above for automotive components failure rate has been plotted (separate plots for sample components) to identify the trend of failure for one year's dataset.
