Assessment of car engineering servicing quality based on failure information

摘要

The article deals with the problem of assessing car engineering servicing quality, the relevance of which increases due to the increase in the level of motorization, risk of road accidents and environmental pollution. The existing methods of assessing car engineering servicing quality are considered. A new indicator for assessing engineering servicing quality is proposed, which is equal to the ratio of failure probability increments before and after engineering servicing. An example of calculation of the proposed indicator for a group of 867 Honda CR-V cars is presented.
