Abstract
This paper analyses the criticality of a technical system using the criticality analysis of system parts from the point of view of possible failure effects. Failure analyses, performed throughout a technical system lifecycle, are generally conducted as to determine and isolate failure causes as well as to define prevention measures and subsequent interventions. The term failure analysis involves a procedure for determining some of the following: 1) failures due to degradation of lubricant; 2) failures due to incorrect lubrication; 3) failures due to poor quality of lubricant; 4) mechanism of failure development; 5) failures due to construction error; 6) causes, types and effects of failures. One of the optimal methods of failure analysis is the FTA-Fault Tree Analysis.
