Analysis and evaluation of the influence of the bus braking subsystem damages on origination of dangers in a sociotechnical system

Operation and maintenance factors and the destructive processes of the technical object elements cause unfavourable changes in the values of the significant functional features, leading to a damage. A damage has been defined as exceeding admissible boundary values of these features. In this paper it has been attempted to identify the kinds and effects of the damages to a selected bus subsystem. Based on the analysis of the diagnostic data, the reasons of origination of the primary and secondary damages as well as their percentage in all the damages to the selected bus subsystems are classified.
