time lapse analysis

Consideration of vehicles with high mileage per unit time to forecast future upward mobility themes.

Reduction of warranty costs

U

Method for early identification of vehicle components that cause high warranty costs.

1

Applicable to all components whose wear depends on the operating time with respect to mileage.

Challenge

A premium car manufacturer wants its future Warranty cases early and reliably.
So far, no consideration of so-called frequent drivers, i.e. vehicles with a high mileage in a short time, to predict future parts requirements and warranty cases.

Solution

Identification of frequent drivers by using the Entropy difference from information theory.
Separation of vehicles under warranty into frequent and normal drivers.
With this separation, top rising topics can be identified via rank differences.
