Probabilistic-entropy approach to ensure the operational reliability of the seaport berth elec-trical contact bollards

Abstract

Reliability analysis of the gradual failure of high current contacts connecting the con-veying units with the seaport power supply electrical network is largely based on deterministic ideas about their degradation. The use the seaport contact electrical equipment indicates the limitations and inaccuracies of such an approach. The long-term studies show that the high marine humidity, turbulent air moisture with aggressive chemical compounds play a substantial role in the wear and tear of electric contacts of seaport berth electrical bollards. The impact of these factors leads to the occasional wear of electric contacts. Thus, we need adequate mathematical apparatus of probability theory and random processes for the reliable results.
