Summary

Studující se podrobně seznámí s obsahem pojmů provozuschopnost, bezporuchovost, spolehlivost, životnost a se způsoby zjišťování bezporuchovosti, spolehlivosti, životnosti atp. Naučí se zjišťovat ukazatelé spolehlivosti R(t), F(t), f(t), lambda (t) a vynášet je jako funkce do grafů. Seznámí se se zkouškami spolehlivosti. Seznámí se s druhy poruch a jejich klasifikací. Budou se zabývat bezporuchovostí soustav a metodami jejího zvyšování (zálohování apod.). Dále se posluchači seznámí se systémy moderní údržby a metodami údržby (údržba podle reálného stavu technických prostředků, proaktivní údržba, korektivní a následná údržba).
